Internet slowing down for no apparent reason at my friend's house
3 replies, posted
So, as you saw, I'm at my friend's house for the weekend and we're [I]trying[/I] to play games online like the fat neckbeards we are.
He's got a 30 Mbit download and 10 Mbit upload speed when the internet acts like normal. However, when he turns on his computer the internet speed slow down to like 0.1 Mbit download. He's been scanning for every single possible type of malware, virus, spyware, ect and found nothing with several different popular programs. It's only when [I]his[/I] computer turns on that the internet slows to a crawl. He's got Windows 8.1 so we checked the network monitoring thing in the task manager and there's like almost no network activity at all. Everything seems to be completely normal on his end. Right now as he's still asleep and I've just woken up, I'm downloading game updates on Steam at like 2.7 MB/s, but if his computer was turned on, it would download at [I]maybe[/I] 5 KB/s.
I'd recommend taking a look the network properties/settings on his computer for that particular network and making sure it's in order. It may also help if we knew whether it's a wired or wireless connection.
It's a wired connection, and his network setting shouldn't have changed at all since before the problems started.
What we've done now is reinstall Windows on his computer, a completely fresh install, but it only helped a tiny bit. Now we've stolen his sister's USB wi-fi adapter to test and it's been another improvement but it's still not quite there yet. At least now the speed is bearable.
Also whether his computer was on or off, speedtest.net showed the same speed results, but the actual speed was much much worse when his computer was on.
The last time I was working on a computer that had weird speed issues, the problem was fixed by selecting the appropriate speed and duplex here: [img]http://i.cubeupload.com/ij7H2K.png[/img]
Also goes without saying that the driver should be up to date
If you're still having trouble, [url=https://www.wireshark.org/]wireshark[/url] can be used to see all network traffic on the problem machine. Also, there's numerous results on google if you search [url]https://www.google.ie/#q=one+computer+slowing+entire+network[/url], some solutions may be applicable
