Crave

Another update: For anybody who is either interested or has a similar problem. After I have checked wired connection with a different router, the speed is the same, as in wireless connection. I have also checked every port on Archer A8, in case there is still hope, but every port gave me the same 0.20-0.30 Mbps download speed. The only difference between them is that some ports give plus-minus 0.05/0.10 better speed than the other one. I don't know what happened with electricity when I was not home, but it seems that the ethernet switch chip/other chip, which controls all ports is completely fried. Hope TP-Link's support is better than MSI/Gigabyte.

Update: I reinstalled Windows yesterday. The system works almost stable (Radeon drivers sometimes cause BSOD), but the Ethernet port still misbehaves. I noticed that there may be some changes. Whenever I run speed test with a cable, it gives me 0.20-1 Mbps download speed and 60-90 upload speed. It seems that something is wrong only with download speed, while the upload speed seems fine. Also, when I change cable to the one, which comes inside with a router, the system registers it way faster than the flat cable. It shows me that my speed is 1 Gbps, both in adapter settings and in LAN port's LEDs. I tried to hard reset router and BIOS after the fresh install of Windows. Unfortunately, I did not get any good results. As the hope dies last, I will play with some of the options inside the advanced tab of PCIe GBE controller and see if something works. If nothing works, I will look into the MSI's warranty. If that is not an option anymore, I will start to look for Realtek 8111H chipset for the replacement work. The last troubleshooting step left is to try a different router, just to be sure that the current one is absolutely healthy. This may be a crazy idea, but can a faulty BIOS/router firmware potentially cripple network after some time has passed from the flash/update?

HWinfo gives no errors to NVMe SSD. I have run SSD benchmarks on it and checked speeds with CrystalDiskInfo. Everything is good. Unfortunately, I can't change the motherboard right now, so I am stuck with MSI B450I for the time being.

Forgot to mention that I have also checked and cleaned both Ethernet port and cable with ear picks, coated in 99% isopropyl alcohol. Still nothing. I already checked and got the results from PCIE NIC. It seems that the port and drivers work fine, but I get random response time outs from time to time, so it seems like something is wrong with the whole system. Yesterday, I had time, so I checked if turning off Windows 10 telemetry somehow screws the LAN port. Turned on telemetry gave no results to my issue.

I get drivers for everything only from a motherboard manufacturer. Chipset, graphics card, SSD/HDD firmware and etc. are downloaded from their reputable manufacturers. I know that you can also get drivers for Wi-Fi/Bluetooth cards, LAN ports and audio stuff from chip manufacturers, but there is also an optimization, which is done by motherboard manufacturers in order for the driver to work more stable with the specific motherboard model. Of course, there are days where manufacturers post faulty drivers, which make everything even worst than before and there is nothing you can do, except reroll to a stable version, and wait for a new stable update. Yesterday, when my PC was in idle state, I got two-three BSODs with some corrupted system32 files, so I am 100% sure that this network problem is connected to the whole system and not just on drivers or router alone. Unfortunately, since I am busy with work right now, I don't have free time to back up and reinstall the whole thing yet. I hope it can be done on Sunday, so I can post an update.

Where I live, maximum speed is 100 Mbps. The only one who gets a Gigabit speed is either some corporation or government. I purchased router and repeater for a more powerful range, 5 GHz channel and a cheap solution to a mesh network. I live in an apartment with lots of neighbours and let's just say that if you look at the Wi-Fi analyzer's channel graph, it looks like a battle royale. Fortunately, absolutely nobody uses 5 or 6 GHz channels, so I get no interference at all. I understand that for network extension, the ideal scenario is to buy an access point and run a CAT6e cable from router to it, but nobody gives me the consent to drill some holes. I used this cable since 2010 and it seems to still work without any problems. I checked the speed on an old Toshiba NB520-10U netbook with it. Both wired and wireless connection gave me 33-35 Mbps speed for download/upload, even though it is capable of 100 Mbps speed. I guess, it is one of the features of Xubuntu. Even when I'm right in front of the router with a laptop, it still shows me that the wireless range is at 70%. The Wi-Fi connection on a PC works even when a cable is connected to another device. The magic happens only when I connect the cable to the PC.

I have done everything you advised me. The screenshots are attached to the reply. When I saw results with a lot of timed out requests, I wanted to check if flushing DNS and reseting TCP/IP will help to solve the issue. After the restart, I was greeted with an auto repair diagnostics windows and then with a message that Windows failed to repair corrupted files. From this experience, I think that I won't even bother with a bootable OS and just fresh install Windows to not only fix the Ethernet issue, but also to fix whatever is broken inside system32 files.

Oh, that's a really good idea. I don't know why, but I forgot that there is a bootable OS thing. Thanks for the information.

To my surprise, this 6 meters Ugreen flat cable works fine since 2010. Never had any kind of issue with connection or speed, but maybe it gives more latency.

I forgot to mention that I reinstalled Windows several times a month ago. As I was trying to reinstall Windows from Legacy to UEFI, I had problems with MSI's butchered BIOS, which supports the Ryzen's all AM4 line of CPUs. UEFI mode just didn't want to work on 2020 BIOS and the on the latest version with 1.2.0.7 AGESA. I guess it won't hurt to try (hopefully) the last fresh reinstall.

Hello everyone. Specifications of a PC: MSI B450i Gaming Plus AC with 1.2.0.6c AGESA BIOS. AMD Ryzen 1700X, OC-ed and undervolted to 3.7 GHz, 1.32 V MSI Armor MK2 RX 580 8 GB, undervolted from 950 to 900 mV on VRAM and -50 mV on every state, except the first and last one. 32 GB (2x16) G.Skill Ripjaws V 3200 MHz CAS 14 HP EX920 M.2 NVMe SSD 512 GB Seagate FireCuda 2.5 SSHD 5400 RPM 2 TB Silverstone SF800-LTI SFX-L Bitfenix Portal case 2 x 80 mm 4 pin Noctua fans 2 x 92 mm 4 pin Noctua fans 1 x 120 mm 4 pin Noctua industrial fan Noctua fan controller Noctua NH-U9S Specifications of a network's setup: TP-Link A8 TP-Link RE550 Ugreen Cat7 flat cable Last week, when I came back home, I noticed that websites opened slower than usual. After running a quick speed test and Steam downloads, I saw that the download/upload speeds dropped from 100 Mbps to 0.20-0.35 Mbps. When I run same tests through Wi-Fi connection, the download/upload speed was 90-95 Mbps. Also, whenever I use the cable, somehow the Wi-Fi connection gives same 0.20-0.50 Mbps speed to any device, which is connected to the network. For a couple of days, I did the following things to try to fix the issue: Contact ISP and let them thoroughly check their side. Everything is fine. Downgrade the router's firmware from 1.11.30 to 1.11.0. No change. Reset the router's settings. No change. Reinstalled all drivers/let Windows install its own drivers/use without drivers. No change. Disable Large Send Offload v2 on IPv4 and v6, put 100 Mbps full duplex on Speed & Duplex. No change. Change cable. No change. Connect cable to another device and check speed on every port. Everything works fine. Reset network. No change. Check for corrupted files in a system. No change. Delete anything that was installed before the disaster. After I deleted 28.0.3 version of OBS and restarted the PC, the Lan speed returned. After some time has passed, the speed has dropped again. Check Event Viewer. There were a lot of informational records and an error, called DHCPNACK. I don't remember the exact error, but It said something about IP lease. At this point, I have two theories: Maybe there is something wrong with a system and I need to reinstall it. Or something happened while I was not home and it damaged either the LAN port or the chip. As an additional information. A month ago I updated the BIOS and changed OS Configuration from CSM to UEFI. Everything worked fine till the last week.

Oh, I see lol. I pretty much learn everything about electronics and other stuff when I am confronted with broken/defective products and there are no good repair shops, who, at least know what they are doing. If you looked at me ten years ago, I was the dude who was calling a motherboard a processor. I have talked about the circuit breaker with an electrician, who installed it and it is the pretty much the best, which can be found in a country. Of course, there is an option of ordering breakers from abroad via proxy shipping, but for the time being, I kind of just want to bring my PC back and finally get back to the internet. Phones/tablets' OSs have just too many limits when you compare it even to text-based Linux OSs.

Um, sorry for being rude. It's just when I learned that the proper and secure way to connect electric cables is tinning copper ends with solder and use tiny terminal block with levers, I was like: "Wow. That look nice, clean and good for easy maintenance. Why the hell nobody does it this way?" In a country where I live, there are no certified electricians. Only the good ones and the bad ones in disguise. Of course, there are companies/infrastractures, who provide services similar to this, but it is more expensive than getting an unofficial electrician or just learning, purchasing the right tools/products and doing it yourself. I mostly prefer the last option, because at the end of the day, you also learn something new.

Should I also replace a breaker? If I remember correctly, it was installed a looong time ago by some "professional" electricians, who connect wires by twisting both sides of copper and shield it with a cheap anti-static black tape. Unfortunately, I don't understand some concepts of how electricity works, so I may or may not know some things, regarding that.

I hope so. I have read that even expensive PSUs can somehow screw your other components, one way or another.

After the spark, I immediately unplugged power cable, put anti-static strap, unplugged every PSU cable and took the PSU away from case. I went all out for safety of components and got a Corsair SF750. Hope it serves me better than Silverstone's "Titanium" PSU.

Hello everyone. Specifications of PC: MSI B450i Gaming Plus AC AMD Ryzen 1700X, OC-ed and undervolted to 3.7 GHz, 1.32 V MSI Armor MK2 RX 580 8 GB, undervolted from 950 to 900 mV on VRAM and -50 mV on every state, except the first and last one. 32 GB (2x16) G.Skill Ripjaws V 3200 MHz CAS 14 HP EX920 M.2 NVMe SSD 512 GB Seagate FireCuda 2.5 SSHD 5400 RPM 2 TB Silverstone SF800-LTI SFX-L Bitfenix Portal case 2 x 80 mm 4 pin Noctua fans 2 x 92 mm 4 pin Noctua fans 1 x 120 mm 4 pin Noctua industrial fan Noctua fan controller Noctua NH-U9S Recently, while I was at work, I was told that the circuit breaker inside transformer suddenly tripped. Sometimes it happens when two air conditioners and microwave oven are turned on at the same time, so they just lifted the switch on tranformer again. After like, one-two hours, it happened again and after that, the whole apartment's electricity went down. After the electrician inspected every room separately, the suspect was my computer. Whenever I plug the power cable to PSU and flip its switch without even turning on the PC, the breaker trips. Overall, the PSU was turned on and off three times. One time, when I was at work, one time when the electrician was testing rooms and another time, when I tried turning it on with a different power cable. The third time was not nice, because I saw a spark in a yellow capacitor, copper coil inductor and two metal oxide varistors' location. That location also has a burnt smell. The PC is connected to a surge protector and a power strip with twelve outlets. I also connected an AC (something like that), router and two monitors (240 Hz and 60 Hz). The PSU is out of warranty since at the time of my purchase, it had three years warranty. It worked four and a half years. I have attached pictures of the internal parts and from a quick glance, the only thing that caught my attention is the copper coil on inductor on a marked location looks not as shiny as other two. I didn't fully check other components, since I don't have a spare PSU. Nothing has a burnt smell or some visual damage on it. Question: If I plug a new PSU and connect it to my components, will it kill my new PSU? TL;DR breaker trips from just turning on a 4.5 years old PSU. Tried different power cable, saw a spark and the PSU has burnt smell. Didn't check other components. Is it safe to use new PSU with unchecked components?

With a mix of Krytox 205 G0 and 105, which makes it Krytox 205 G2. Used 00 brush, and lubed parts only with a shiny tip instead of white chunk of Krytox. The guide I used for lubing is this.

Hello everyone. For information, I use modded (tape mod, Neoprene foam between PCB and plate, and on bottom case) Varmilo VB87 with lubed and filmed Gateron yellow switches. I use it both and at home and work, so it gets transported a lot. I experience issue with double clicking/no click on some of the switches from time to time. When I soldered switches, first month or so was good and everything worked. After some time passed, one of the switches started to double click or no click at all. I switched it to a new one and the life became good again. After like a week or two weeks, another two switches started to malfunction. Yet again, I switched them to new switches. Right now, about like eight switches have the same issue. My question is, can a very light layer of lube on copper leaf or tiny dust, which may/ have entered inside switches cause this? If not, my only guess is that I just got a bad batch of switches.

Sometimes, adding a little 90-100% isopropyl alcohol inside works wonders too, but most of the time, if the switch is malfunctioning, it means that its time has come. All switches have not only physical lifespan, but also electrical lifespan, and if it's the latter, there's no fix to that other than to replace the switch altogether.

Thank you for the information.

I see. Thank you for the answer. Strange thing though. AM4 is supposed to support all Ryzen series, so why would they drop some of them from time to time?

There were reports about bugs and malfunctions when 3000 series were considered new thing. I'm wondering if after 5000 series, it's safe to update it. On the other hand, I agree with you on the rule "It it isn't broken, don't fix it".

Hello everybody, I have MSI B450i ITX motherboard, Ryzen 7 1700X, MSI RX 580 Armor MK2 and G.Skill Ripjaws 3200 MHz 14 CAS. I read on some old posts that 3000 series BIOS updates make the 1000-2000 series buggy. Currently, I use 7A40vA4 version of BIOS (before the 3000 series BIOS update), and I'm curious if by updating BIOS to the current one will ruin the compatibility between 1700X and motherboard? Unfortunately, this motherboard doesn't have any kind of BIOS backup to downgrade the BIOS.

As Dudis already mentioned, clean, re-paste/replace thermal pad if it has any, maybe even reinstall OS just to make sure the HDD/SSD is clean too, undervolt if the BIOS has this option, and put your laptop a little higher than usual with cooling pad/laptop stand/erasers.
