The computers can connect to each other for maybe up to an hour after the router is reset, but for some reason it just seems to stop working. Also during this time, file transfer is incredibly slow.
A while ago I saw on here someone else having the same problem, but fixing it after deactivating their wireless N, so I tried initially thinking it worked. But then finding out it was just because the router had reset to update the changes.
Umm, yeah so if anyone has any ideas what could be causing/how to fix this any help would be very much appreciated :)
