Hey everyone! I'm trying to pull more from my FreeNAS Box to maximize performance. My development box which also hosts my FreeNAS install is running 2 Xeons, 144GB Ram, 256GB NVME L2arc, 3*3TB Z1 My client device is a 2014 MacBook Pro retina 15 inch with DGPU. It has 2 thunderbolt 2 ports and 2 usb3.0 gen 1 ports. Since Thunderbolt 2 gear is wicked expensive, I was thinking of using the USB ports for networking, and with the advent of 802.3BZ adding support for 5Gb/s and 2.5Gb/s being able to hit 5gbit on my laptop. My thinking is I could connect the server via SFP+ to the crs305 (a 4 port SFP+, 1 gigabit rj45 switch ), use an RJ45->SFP+ converter to connect to my current cat6A cabling, then terminate at the laptop with a 5G Ethernet to USB3.0 adaptor. I was wondering if anyone was aware if the CRS 30X (in my case I'm looking at the 305) supports the 802.3bz specification for 5G and 2.5G. Otherwise, if the adaptor supports auto negotiation with the usb to ethernet adaptor, do I have to care about the switch supporting it? Would it essentially just see the other device as a slow 10G device? More than happy to provide clarification, other data Felix CLC

Our business recently got a 25/25 fiber connection through Spectrum Enterprise. Since we've gotten it, we've noticed, particularly when there is a little traffic on the network, the speeds will fluctuate substantially. Is this normal? With fiber being dedicated, I would have assumed that it was much less susceptible to speed drops from network load. We have about 15 people working in our office, all of which have file syncing enabled via OneDrive for business. Outside of that, it is really just email and other normal web browsing. I want to verify if this is a network or ISP issue because they claim we are "Over-utilizing" the circuit.

About a week ago I had my ISP come out to install fiber lines for gigabit internet. They ran the lines fine no problem (however they are still above ground in my backyard and have yet to be buried, said someone should be out in around 14 days to bury). It has been below freezing point past few days but no "severe weather", some light rain here and there.First day of having it installed and setup it ran completely fine no problems, at this point I had no router, just the one installed by ISP on my wall, so I was directly plugging into that, no wi-fi or anything. I purchased a xr500 Netgear pro gaming router after a day to set up all my home connections, internet seemed completely fine and stable for about a day. Late that night after purchasing my xr500 the alarm light went completely red and service was gone (on the wall "router", not the xr500), after calling my ISP and having them come out and take a look, according to them the connector from the line outside to inside the house was bad and they had to replace.They told me light signal coming to and from the house was fine but signal inside house was bad, which seemed to be resolved after the connector switch. Internet went back up and I had a planned gaming event with a lot of friends to attend to so I went to rush back into it. At this point I immediately realized discord was being extremely robotic for me and I was getting severe packet loss in discord. I spent around 2-3 hours on Tech support line with Netgear, seeing as if I plugged directly into wall modem everything seemed fine. Tech support told me my router might have remembered a bad data connection due to fiber line being messed up temporarily, performed multiple factory resets and tweaked some settings and didn't help even slightly. Had to get off the phone with tech support due to gaming event and just played plugged into wall modem. I noticed some roboting issues in discord at this point, just nowhere near as severe as if I was plugged into xr500.Finally I decided to return the xr500 for a new one to eliminate the chances of that specific model being messed up, and it didn't help at ALL, roboting issue still there severely, some webpages take forever to load, service seems spotty. I've been running pingplotter the past day or two trying to pinpoint whats going on, I had severe packet loss running to discord servers, twitter, and even google. However I decided to run a longer length pingplotter while plugged directly into wall modem, can post screenshots.Any advice and or suggestions would be great.Also if there's any IP's I need to hide on the pingplotter screenshot that would be nice to know, don't wanna accidentally give away sensitive information.

My ISP offered me fiber internet to the house, Everything was fine until I wanted to use the LAN ports on the back of the modem router switch access point combo they gave me. It didn't work. W/ a bit of research I found out the router is so broken only wifi works ( the DHCP server only works on wifi and doesn't work on LAN ) and I am tired of trying to fix it, because many people have reported the same problem. Either way, I was planning on buying this Mikrotik Router: https://mikrotik.com/product/rb4011igs_5hacq2hnd_in . My questions are: 1. Is the SFP+ port an input that I can use for the fiber that comes from my isp? 2. My isp gives me 1 fiber terminated w/ an SC connector. If Q1 is true, is there a way to convert the SC fiber to an sfp+ fiber, and, if so, with what equipment would that be done(product names and types for adapters?)? 3. If Q1 is false, recommend me some good fiber modems that accept an sc fiber input, if you know any. Thank you in advance.

Hello! I mean... Hodor.... Sooooo, I recently got hooked up to some delicious, delicious giggitybit fiber to the house, yay! But; like so many others, I too, am looking for a way to use my own equipment instead of the notoriously unreliable, security flawed, packet inspecting excuse for a gateway... I found have so far been able to successfully eliminate the AT&T gateway (Arris NVG589) from the network and substitute it with my own (Netgear Nighthawk X10 R9000) and both internet and TV have been up for about two days meow. However... The Uverse digital phone does not work and I need help understanding how VOIP works... I am still waiting for my number to get ported over and I was assigned a temporary phone number until that happens in a few days and I am hoping to find a working solution before then. I am able to get a dial tone when the phone is plugged in via RJ11 into the NVG589 but I am not sure how AT&T authenticates that VOIP connection. The IP gets authenticated through the ONT when it sees a connection to the NVG589's WAN MAC address and once the connection has been authenticated and as long as that connection is not disconnected, it remains authenticated. But I am thinking this is most likely not that case for the phone... Can someone please help me understand the VOIP authentication/handshake process? I believe AT&T uses SIP protocol. Lastly, because the Nighthawk is cloning the NVG's WAN MAC address and it would defeat the whole purpose of the previously mentioned concerns leading to why I am trying to do this bypass in the first place, I can't have the NVG in front of my Nighthawk and I want to avoid any packets besides home phone passing through it (The NVG589); what would happen if I isolated the NVG with Dot1Q behind the Nighthawk's NAT? Could it get VOIP to work or will it break something? If not, can someone please help me find a solution? Thanks

Hey. So I'm getting a new fiber connection next month and want to upgrade my network while I'm at it. Unfortunately the ISP is AT&T. I fought with them in store and on phone, but they don't allow you to use your own modem. You must use their modem/router combo. I've read online you might be able to force it into a bridge mode although it isn't supported. I don't trust their device at all, but should I put up and use it as is and just connect it to my switch, or should I try to bypass it and hook a ubiquity router between the modem and my network? Below is a map of my network.

I have been looking into connecting two windows computers directly together via 10gig fiber. For this I was looking to use a sfp+ nic for each computer and a Multimode LC sfp+ module for each nic. Is there any special configuration that needs to be done so the computers would be able to access files on each other? As a note this is purely a thought I had and as such you don't have to worry about drive speed limitations or if there is a better way to complete the task.

I'm getting a new apartment and am looking for internet. The two plans that I'm looking at are either the 120 down and 20 up cable plan that is offered in my area. Or the 50 down 10 up FTTN (fiber) network in my area. I was told that with fiber I get some sort of dedicated line so that during peak hours is not interrupted. Can someone give me some advice?

This expansion card is surprisingly cheap, wonder what the latency would be like gaming over it to a remote rig. https://www.amazon.com/10Gtek-E10G42BTDA-Ethernet-Converged-X520-DA2/dp/B01DCZCA3O/ref=sr_1_2_sspa?s=electronics&ie=UTF8&qid=1532225828&sr=1-2-spons&keywords=10g+network+card&psc=1

Got about €300 to spend, need wifi for two floors and i have a cable between the floors. A router on the first floor will only mostly cover the second from my experience so i need one upstairs and one downstairs unless they are really good. Think the floors are pretty hard to penetrate for 2.4GHz and then i cant imagine 5GHz will be any better. I really just dont know what i should get for the money and how i should configure it to make it all nice and stuff im not clueless about networks, but i cant say i know much more than the basics tbh. I want dualband and i reafuse to touch ToiletPaper link. If you need floor plans or have any questions just tell me *edit*¨ the speed is going to be 100 up 500 down and mesh is fine, no clue if its better but i could probably mount that too

hi does anyone know how I can connect more than four devices to my router at the same time? Did i configure it wrong?

Hallo guys, I currently planing to upgrade my pfsense router (because i get a new fiber connection). Basicly I want to go fiber all the way, 1x10Gb/s for my server and 1x10Gb/s for my main pc and then I still need 1 port more for my WAN connection. My Idea was to buy a QSFP+ NIC because you can split 1 QSFP+ port in to 4 SFP+ lines but are the 4 lines individualy configurable so every line as 1 NIC? Many thanks in advance -DJ

So at home I have gigabit fiber and a gigabit capable router. But when I download anything I can only get about 350Mb/s per second (over Ethernet cable). I ran a speed test on my desktop and got 350Mb/s, then I started the same speed test on two desktops at the same time and they both got about 300Mb/s. Then I transfered a 20 gigabyte video file from computer A to computer B. And I got the full gigabit transfer speeds. So I don't know what the hell is going on, any help? The router is the ASUS RT-AC68U

I'm trying to hook up my GTX 1080 to my LG 31MU97-B, both of which have Displayport and HDMI. No problem right? WRONG. For two reasons: 1) the computer and monitor are far away from each other (cooling, noise, space, etc.) and 2) The aspect ratio of the monitor, 17:9, is bigger. This is a 4K display capable of 60Hz with 10-bit color and Chroma sampling of 4:4:4. If I remember correctly, it's what LMG uses. But why specifically is this a problem? Bandwidth. For those of you who don't know, Displayport standard 1.2 is certified to carry up to 17.28 Gbps. HDMI2.0(a/b) is able to carry marginally more at 18Gbps. This monitor isn't UHD 4K(3840x2160), but rather DCI 4K(4096x2160). Factor in everything else and you have a 4096x2160@60Hz/4:4:4/10-bit signal with a total bandwidth need of about 19.11Gbps, just barely over what older cables can do, even at regular distances. This HDMI port on this monitor can permit the passage of the described signal, but capped at 30Hz (24Hz depending upon who you talk to). "But this monitor's Displayport cert. is 1.3/1.4. Just get a cable and call it good." ... Were it so easy... I need a 30m/100ft cable. Regular (to quote Linus) "peasant" Displayport cables begin to crap out after 10ft. I have a run in excess of 80ft. The best solution in this case is to go fiber optic (hence the title). Why 100ft then? Have you tried looking for 80ft anything? But really, I'm looking for 100ft for future flexibility. These kind of cables are not cheap per unit; but, if you pay a little bit more up front to get a slightly longer cable than what is needed, you've covered your future self. I digress to cost though. I can't find anything lower than $600 and looking for anything closer to 80ft doesn't really help! I'm trying to aim for a price point of $150-$250, maybe $300 on this one component as I'm already WAY over budget. The astute among you may recall an LTT video covering the 100ft Corning USB 3.Optical cable. I picked up the Thunderbolt variant dirt cheap for use with my peripherals, external drive, and my other, "lower" resolution display. It's great! And yes, Thunderbolt cables (not 3) can be used as Mini Displayport, but to change the ends to regular Displayport with adapters that conform to Displayport 1.4, in both directions, that won't interfere with the operation of the fiber optic cable is not that easy. I'm not against the idea, but good luck finding adapters that WILL, beyond a shadow of a doubt, work with a fiber optic cable. Which conveniently brings me to why I'm here... The point I'm trying to make is: I need a 100ft fiber optic Displayport cable that can carry a signal in excess of 20Gbps. I'm doing my best to not regret this project. My wife is already annoyed with how long this has taken. That's where I'm at. Please help me! :-(

I recently acquired a Cisco DS-C9124-K9 24-Port Multilayer Fabric Switch. From my understanding this is used for SAN traffic, however, I would like to use it as plain 4GB switch for my servers and PC. I have some experience with Cisco switches, however I have no idea about this one in particular. How would I go about setting this up and which pcie fiber cards will I need to purchase? Any help will be appreciated. I will link the product data sheet from Cisco. https://www.cisco.com/c/en/us/products/collateral/storage-networking/mds-9124-multilayer-fabric-switch/prod_bulletin0900aecd80575393.html

Hi, Recently my ISP started providing a fiber connection that gets up to 1gb/s of download speeds. after they installed the new router and hooked me to the fiber network I had 800mb/s download and about 200mb/s upload. 2 days ago I replaced my motherboard with Asus ROG STRIX Z370-H GAMING (ofc CPU and RAM aswell) . It did not require formatting my boot drive, it just worked, I installed some drivers, and basically software wise I had the same exact PC, BUT since then for some reason my LAN is capped on 100mb/s speeds and I cant find any way of changing it, nothing works. if anyone can help me enable 1gb speeds on my motherboard it will be much appreciated.

Hi So soon, we will be switching to a fiber connection from DSL connection. But from what I've heard from most of my friends that are currently subscribed to the same ISP, they are giving out crappy routers. I was thinking that I could reuse my current router (TL - WR840N) from TP Link as a substitute for the router they're giving out? If I could, is it okay to use a normal ethernet cable like a cat 5e as a connection from the provided router to mine? Wouldn't it affect the broadcasted speed? Sorry if this sounds like a dumb question, I'm no brainer when it comes to networking ? But all replies would be appreciated Thanks in advanced!

Hi everyone, I'm just looking if anyone can give advice on why i would get such horrid speeds over wireless at night where i struggle to load a 144p video on YT. During the day over LAN i get 100mbps download and 40mbps upload. Wireless i get 20/30 during the day where it should be 100/40, and over night it is so unstable i get "internet is unavailable" Getting real sick of paying for internet speeds i rarely get over wireless. Thanks, Karbzee

Hey guys, I need some help with my network setup. I recently got an internet upgrade from my provider, they came out and replaced the cables to fiber ones and they installed a new router too. The router that they installed is quite bad, lan is okay little bit unstable but it's usually fine(900mbit/s) on the other hand the wifi is really bad, usually it's 30mbit/s and sometimes 50mbit/s but never more. It's a free router from them, didn't expect better performance so i should just upgrade it to a good one right? Here comes my problem the router they gave us has a fiber input and i only foudn routers with ethernet input, but i saw some converters which could work but there is another problem, my router has the phone output too and with those converters and an ethernet router i couldn't use the the phone. So i need help what stuff i should buy to be able to plug in any decent router with ethernet input and still be able to use my phone and TV. Sooo the current setup: FTTH receiver: -SC APC input -SC APC output -TV cable output(coaxial cable f type from what i can tell but it has no labeling) Router: -SC APC input -4 ethernet output -phone output(RJ11 i think) and of course the router is connected to the ftth receiver with a sc apc cable Thanks for the help in advance. PS.: sorry for my english i'm not a native speaker

Hi, I just updated my internet provider and I got some Fiber at 40 down and 40 up. Well that's what I get from connecting a cable directly to the router from computer or with Wifi from cell phone (when I'm close, not in bedroom where computer is...). Thing is that I have a CPL in the bedroom connected by cable to my computer and it down at 10 and up at 6 (tl wpa 4220). So basically what's the solution to reach the full or near full potential in my bedroom without doing holes all over the walls at my place (i calculated that I would need at least 50m of cable to reach computer from router) ? I live in europe in a recent building and walls are pretty thick (glad I don't hear anyone aroung though). thanks all

Hello I have recently installed telus fiber 150 I think and they gave me this white box that the fiber connects into...I would like to hook up another router and have my own privrate network other than my family's, how would I go about this? there is a few "data" ports on the back of the white box and Im not quite sure but it seems like only data1 works.. I would like a seperate network from everyone else, I have a cheapie router its a linsys e1200. Thanks for reading, dont know much about the rules on LTT forums nor about networking haha.

Hello, I need help deciding what router that is capable to connect fiber. Before we start i would like to add that it appears i have fiber to the home, today the ISP came over dag a hole in my garden passed the fiber optic cable and them drilled a hole into the wall of my house and passed the cable to be next to the already existing router. There, there is a box that terminates the fiber coming into the house and has a laser warning, from that box another fiber optic cable connects to the ISP router. So it would appear it is fiber to the home. That is why i need a router that will have a port for fiber please help. Price range can vary because i dont know what the price for such routers is. Thank you PS. it should have DHCP, so it give the same internal ip address according to mac address. It should also include priority and port forwarding

This is my first post on this forum as I don't know anywhere else where this would decently fit. But I have been using Verizon Fios for awhile now, and want faster speeds. Currently I have 50 Mbps download and 10 Mbps upload. I called Verizon and they said this is the only speed they offer in my location, and I want to know if it makes more sense switching to cable and getting a 200 mbps download. If it helps, I live in an apartment building but knowing the people in here, they won't be doing much HD streaming or downloading any large files.

At the studio that I am working at we have set up a FreeNAS server and it has been working great. We use Fiber Channel cards and iSCSI to push to the Machines. When we set this up a few months back we had Two Machines running as clients. Both machines are identical 2010 Mac Pro Towers (souped up quite a bit). We added a 3rd, identical machine with an identical fiber card. This machine does not talk to the server! The machine sees the card, the connections, everything. But the server doesn't seem to "push" the iSCSI drives to it. If we install one of the Fiber cards from the two working machines it mounts right away. We thought it was a bad card, got a few more and we get the same result. The FreeNAS server only pushes to the two original machines. No where can I find this same problem or even how to add the machine to FreeNAS. From my knowledge I don't have to as long as its networked as the other two working machines. We have tried every combination of hardware and software to no avail. We dual boot Windows 10 on these as well and the two "working" cards mount up just fine, no configuration, but any other card does not. There is almost no chance that out of the 6 cards we have now, only two happen to work! Have also tried every combination of the SFPs from the cards too, no change. If anyone has any idea how to fix this or even get us on the track to fixing it, it would be incredibly appreciated. This has been driving us insane! Thank you all very much in advance! *EDIT* The cards are LSI 7204EP-LC 4Gb Cards and the switch is a 4Gb Fiber Channel Switch. The two working machines needed NO configuration to accept the target drives and work no matter the configuration of the switch, even directly connected.
