a) you switch to another channel (try all)?
b) change the location of the laptop to, say, 1 feet from the router?
c) try another dongle?
d) try another router?
I've been using my homes wireless internet for years now and it's always worked fine, nice and fast and without and hassle. A couple of weeks ago for seemingly no reason, the connection still says it's the same but the speed has completely dropped off. I can no longer stream from youtube without having to wait an age for it to load and I'm desperately trying to download The Witcher 2 which at it's current rate (70-80kbs) will take over 2 days! Previously when downloading games the rate has been around 250kbs. I use a wireless dongle which pick up the signal from the house router and I've tried it in various USB just incase that made a difference. I've also ran several virus and anti-malware programs to make sure I don't have any sneaky trojans slowing things down.
Does anyone have any ideas why this has happened or what I can do to get the speeds back to where they were? Or are there other posts with similar problems that you can link me to?
Any suggestions will be greatly appreciated!
