Ethernet capped at 100mbps

Hello, I've recently connected an ethernet cable to my PC and have been hitting 300+ mbps. However, a couple days ago I've been experiencing new issues where the speed was capped at 100mbps, and wouldn't go up, no matter what I did. I've watched videos, read threads, posted on reddit and have done all the typical fixes that I've been told to do with no success! Now I've found out about the Virgin Media community and now need help as this issue could be something related to the router! Thank you in advance!

Re: Ethernet capped at 100mbps

Hello

Well without knowing what has been done, it is going to be near impossible to advise on what the next steps are so sorry if I am repeating what you have done.

Have you changed the Ethernet cable with a known good cable of Cat 5e or greater it will be marked on the cable ?

Is the Network Card running at 1.0 Gbps ?

How are you testing the speeds, I would say the best test is wired direct to the hub with a Cat 5e cable as that rules out any other equipment ?

www.speedtest.net is the best site.

Can you please post your network stats from the hub
Open a Web browser (e.g. Internet Explorer) and enter the address http://192.168.0.1
Note: If you have enabled Modem Mode on your Hub 3.0 you will need to use 192.168.100.1 instead.
Posting the stats by copy and paste will remove all personal information so no breaches.
Do not login but click on where it says "Check Router Stats" and then copy and post from the following 4 tabs, Downstream, Upstream, Configuration and Network logs (if they are pasted then all personal information is * out) and we can check your power level, also while you about that can you please go around and check that all connectors to VM equipment are hand tight. Also while doing this please check for any damage to cable, or un-terminated connection without either coax or a terminator.
Also please run "Check service status" at the top right of this forum and call 0800 561 0061 to check for local issues.
Also one think you can do is too signup at https://www.thinkbroadband.com/broadband/monitoring/quality and setup a broadband quality monitor which will keep an eye on you connection by sending a small amount of data to the hub asking if it still on.

Regards Mike

Re: Ethernet capped at 100mbps

Can you Login to the Hub Settings and navigate to the Connected Devices page - what does it report the 'connection speed’ as for the cable connected device you used for the speed test ?

Re: Ethernet capped at 100mbps

Can you try it this way and see what you get.
------------------------------------------------------------
As you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a known good and working Cat5e (or better) ethernet cable, directly to the Hub which you have put into “modem mode” (see VM website for “How To”). Test at speedtest.net (not the App!) to your nearest VM server - try on 2 different browsers.

If they are still low – boot the device into safe+networking mode and try again.

There are many posts on here where unknown/flaky software, old network card drivers, corrupted browsers or other connected devices are limiting speeds on tests.

Re: Ethernet capped at 100mbps

That is the maximum speed you will get due to hardware restrictions.

Either the ethernet cable isn't to spec or is a bit iffy or the device Network Interface Card is too old or at the wrong settings.
