Alright so I've been noticing something strange since I installed Elementary OS (Ubuntu 12.04) on my laptop. Whenever it's booted up and running, I literally can't use any other device in my house. Signing in on my PS3 just leaves me with an error or is extremely laggy, and using online apps or Safari on my Ipod touch is near impossible.

However, once I shut down my laptop, I notice that all devices return to normal and share bandwidth in harmony.

Is there a fix to this, or is it a glitch that can only be reported? I have no start-up programs, and rarely use anything heavy such as torrent clients... So essentially there shouldn't be a problem.

Thanks everyone.
