I've been searching for an answer to this for a while now and can't find anyone with a similar issue anywhere. Whenever I turn on my desktop computer I can no longer connect my laptop to the internet unless I have it in the exact same room as the router. They both run a wifi connection neither one is wired to the router. The router is a Linksys E2500 router and other than this problem seems to run fine and it's brand new. Whenever I turn the desktop computer off the laptop once again can connect to the internet in rooms separate from the router. We have a 15 Mbps internet connection so I don't believe it is internet speed that would be affecting the laptops ability to connect to the router. I thought that could be it when we actually had slower connection up until about a week ago. However since upgrading the internet this problem hasn't been remedied. Any help that might be provided is greatly appreciated.
