I've been using other Linux distros for a while but this is my first time with Ubuntu. I've installed it on my PC and I seem to have problems using the internet from time to time. The PC it's installed on has a USB wireless adapter which ubuntu recognised and it's what I'm currently using.
The PC is connected to my wireless router and it's using the internet without any problems. I have 80% signal strength and I'm able to download with ~2.5Mb/sec.
The problem is that all of a sudden, for no apparent reason and at a random time, I stop being able to connect to the internet. I'm still connected to the router and the signal strength did not go down. I simply cannot use the internet unless I disconnect and reconnect to the router but it will eventually happen again.
Does this problem sound familiar to anyone?
