My Logitech G7 mouse becomes laggy whenever I am downloading at high speeds. I have a belkin wireless router, but I had the same problem when I was using a linksys router too. I have tried switching channels on the router but it doesnt really seem to help. I have also tried putting the router, mouse receiver, and wireless receiver as far apart as I can...but I still have the same problem. What can I do to fix this issue? This is my second G7, the first one was insanely laggy at all times, and at the time I thought it was a problem with the mouse so I exchanged it. This one only does it while i download, so I'm guessing its interference. Any solutions? I really like the mouse and want to keep it.
