I got fibre optic a couple of weeks ago and the speeds were awesome, from a 3mb/s download speed to a 35mb/s. I was running with these speeds for quite some time without any problems, until it randomly started dropping (down to around 4-7mb/s). My first thought was that it was a problem with the internet, however my mums computer has been running at a 30-35mb/s download speed this whole time. Re-plugging my ethernet cable usually worked, but not always. Here I thought there were 3 main things that could've caused it:
I re-installed Windows 7 on my computer 2 days ago, however the lag still persists. So this cannot be the issue.
Bad ethernet cable
I bought a new ethernet cable at the same time fibre was installed, and I have also tried my mums PC upstairs using my cable and she was fine all day.
Faulty network card
As I said, I swapped both mine and my mums computer around for a day. Both computers ran at full speed without any problems, no drops, nothing.
So right now I'm not sure what is it. I've tried many different things and I'm back in my original place with the lags happening again. Re-plugging the cable isn't helping me anymore though and there's nothing I can do. My ethernet drivers are up to date as well. Here's 2 speedtests I did today, one before the drop and one after:
you have less on wireless that ok it is either your network chipset or the router keep it on the wirelees dongle for a while and if the speed stay the same your network need to be check on your computer also plug your mom compu to the net on the slot you where using in the router,you could also get a network card to replace the internal one .
