wireless n Crazy Slow lan speeds or my stupidity?

[VE5LPL]

So I have a virtualization server and I need to copy some .iso files over to it. I am using a laptop connected via a wireless n access point and the server and ap are connected to a gigabit switch (but due to the ap only having 10/100, theoretically it is limited then to 100MiB/s?). So I tested the link by running some tools and found that I was getting 12.8MiB/s [1.6 MB/s] at the best in my tests! I am I going nuts here thinking I should expect faster or is something really not right here? and why am I getting an eighth of the speed I should (I do realize that some speed will be lost just cause since you never get the theoretical network speed you wish for but still an EIGHTH)?

Here is a screen grab

                                                                                                                         ^ ONLY 1.6 MB/s ???

 

Thanks for anything in advanced

Are you using Wi-Fi? Try an ethernet connection.

Then there's your problem. 

 

Many people do not understand that wifi is for connectivity, not speed. Wifi in all reality is pretty slow.

But still I am getting Wireless B speeds on a Wireless N network...

What? You're getting your normal speeds over the internet but not over your lan?

If that's the case, then it's probably one of the hard drives on the computer that you're trying to transfer from.

I think you got your units mixed up. Network speeds are usualy told by using megabits (Mb) and not megabytes (MB), also a MiB is 1024 bytes and a MB is 1000 bytes, so 12,8MiB/s is not 1,6MB/s: convertion, although many uses just MB for MiB...

 

And you can't get the full 100mbps (12.5MB/s) anyways. but to maximize your upload speed: Disconnect any other device than the on you want to upload from, and stop any programs on that device that may use any network at all.

No, it is send just zeros over generated by the CPU (if you know about linux [/dev/zero]) and the other computer is just dumping it [/dev/null]

Nah, I was getting 1.6 Megabytes (per second) and 100 Megabits (per second) is the theoretical max so 100 Megabits(per second) is 12.5 Megabytes(per second) and 1.6 Megabytes (per second) divided by 12.5 Megabytes (per second) is 0.128 or 12.8% of what I should be getting.

Maybe the NIC that you're trying to transfer to is bad? Seems like the only logical thing right now.

Nah, The NIC can handle faster speeds as I tested with a 802.11AC network in the laptop and the server is running a Intel Server grade nic...and I doubt that it is the problem otherwise I would not be able to send this reply.

Note: My Internet Speed is less than 1.6MB/s anyway...So it is "Normal" for where I live

What AP is it? since it has a 10/100 port it cant be that fast, and wireless is always slower then rated. if it is a g 58Mps AP, and accounting for signal loss it could be running at lets say 30Mbps which is 3.7MBps.

 

the NIC should tell you what speed it think it can do.

It is a Gigabit nic on the AP. so why am I getting like 802.11b speeds on a 802.11n network? and the ac network is faster so that would then again cancel out the AP nic as a cause.

so it is a n AP? again what is the AP, some are faster then others. how far away are you from it, any obstacles?

 

What is the speed the NIC is negotiated too? it can be a 300Mbps NIC and AP but negotiate to 80Mbps (or what ever) due to signal quality.

 

It could be a 802.11n AP rated for 150Mbps, but is getting channel interference which bumps the speed down.

 

Have you tested on a cabled connection?

Well I am not at home right now...But I am using a (guessing by memory) a Netgear or like D-Link AC Router. I have it setup to do a 2.4GHz 802.11n network and a 5.8GHz 802.11ac network, on the 2.4GHz network I got the speeds in the screen cap from the first post. I get (if I remember correctly) about 3 MB/s. During that test I was about 15ft (max) away with a wood sub floor and laminate flooring between me and it.

on a 2.4GHz signal with 3MBps seems like a poor signal. I think your speed issues is all wifi based.

Ok...but why is it still stuuuuupidly slow?

well I don't know the rated speeds of the AP and NIC, but I would say it is maybe 150 Mbps negotiating down to around 30 Mbps due to signal. I can't say for sure until you give me that information and if possible the NIC's negotiated speed.

 

I personally feel wifi has a lot of misconceptions. not every 802.11n or ac device is the same, some are faster and/or some have better range. Also AP/Routers will get auto set to lower speeds to allow for greater compatibility. (like a legacy device on the network can make a AP go slower if it is not dual band.)

However this my client is a Q4 2016 Device so legacy shouldn't be an issue

mentioned it for info, and I mean if you have a other device on the network that is old it can force the router to use older standard which is slower. (mostly not a big concern now)

but this slow... (slowest thing on our network may be a iPhone CE)

I can't give you a definitive answer with out the information I asked for. I just feel that this is what I think it could be. it could be something else but it is best to eliminate this first then look at other things. The most useful information would be the NIC negotiated speed, if it says something like 30Mps, then that is your problem.

I'm at work about 30min drive away so...wait till like 6:00CST...
