Constant LAN disconnects
I just got back from holiday so the pc hasn't been used for a a week but since then my internet connection has been intermittent in the extreme, this is not an exaggeration, it cuts out for 12-13 seconds a time on average I guess about once every 3 minutes, though it can go 10 minutes occasionally without a disconnect. This only affects my PC as its the only device wired for the internet, wifi devices do not seem affected.
I have had this problem before but my previous solution has not fixed it this time. Previously I thought it was my ethernet cable so I replaced it, no change. Then I thought the issue was with router or ISP (Virgin Media/Superhub 3), so I ran the diagnostic tool which said:
"the device connected was running at a lower speed of 100mbps and is not utilizing the full available speed"
I spoke to my ISP but after I contacted them they told me that it seemed like my network card could be throttling my connection as it couldn't be the cable because that was new. I checked int he network settings and noticed that the Speed and Duplex was set to 100mbs, I switched it to auto negotiation and the problem went away.
I have checked that this time, it was still on auto negotiation so I switched it to 1.0 Gbps full duplex to see if that helps, no change though.
I don't know why, but if I am downloading anything, for example, a game on steam, the connection is fine and stable for the duration of the download.
I just want to add that I have already asked this on another forum and they are as stumped as I am, feel free to have a look at what has been suggested there but the gist is:
All drivers are up to date.
WiFi is not affected.
No Virus or Malware found.
BIOS is up to date.
Thanks in advance for any thoughts or ideas.
