Ethernet speed slower than wifi
#1
Hello, I have a situation where my ISP (virgin media) upgraded me to 100Mb/s it was about 75Mb/s before (as measured by speedtest.net) its not exactly a problem since most people would be pleased with these speeds, its more of academic interest..

I occasionally checked using my Windows 10 Desktop Acer Aspire to see if they had completed the upgrade but it never went much above 70Mb/s for a week. Just to see I checked it on my tablet 5G wifi connection and sure enough it was 102Mb/s so the upgrade was complete.

I wondered why the desktop was slower when the ethernet cable and wifi signal are coming out of the same Netgear 6220 router.
I did the following checks..

1..checked the firmware on the router is up to date which it is, I dont think it is the router anyway as it can provide 100Mb/s wifi
2.. checked the driver on the Nvidia n series network controller on the desktop was up to date, it is as up to date as I can make it but I still think it should be capable of 100Mb/s anyway
3.. As I couldnt be sure of check 2 I changed the method the desktop gets online when I plugged in a USB3/LAN adapter and plugged the ethernet cable into that, the result is the same speed of 70Mb/s so I think this eliminates the Nvidia controller as a suspect
4.. the last thing I can think of is the ethernet cable itself, I think it is Cat 5 so I have ordered a Cat 7 cable which should arrive in 3 days

does anyone have any other ideas I can try out in the meantime, or do they think the Cat 7 cable will improve things?
thanks
Craig

UPDATE-- the Cat 7 cable arrived and it made no difference at all, pity as it looked like a nice quality cable. I think this is the end of this thread as it isnt really a problem and may have no solution

This is a complex issue which would be very difficult to help you with without having a lot of details and screen shots.

  1. Could be a issue with computer hardware 
  2. Could be a issue with windows, software or drivers
  3. Could be a network card issue
  4. Could be a Virginmedia issue
  5. Could be a Virginmedia hardware
This list goes on and on. There is loads of variables to these sort of problems.

I know I said the thread was over but I was working away on my own on this, since I got a reply here is an update on this 'academic issue'

I plugged my macbook laptop into the router and am getting 102Mb/s so the problem is purely with the Acer aspire Desktop

I tried various things like stopping all background apps, changing the bandwidth settings from 80% to 100% via the gpedit.msc group policy settings
Looking at resource monitor/network to see if there is anything hogging the network.. nothing remarkable
Temporarily disabling windows update service

nothing made a difference, it almost seem to be throttled around 70mb/s

Anyway if I ever get a solution I will complete this thread, a part of me thinks it might turn out to be quite useful info as I try to head into the 100Mb/s area on a 2011 computer!

Try another network card, they are only cheap.

Yes a good call, I am fairly sure that would improve it, however I used up my 2 PCI slots with USB3.0 and graphics card.

Will just have to forget this one I think, not a major issue

UPDATE 02 Oct this whole issue was caused by my using the Speedtest.net microsoft store app on my PC, when I tried it using the internet browser speedtest.net it displayed 92Mb/s instead of 70 Mb/s with the app !
