Earlier on today, my laptop just suddenly stopped being able to detect my router, my housemates can all still access it, but for some reason when I go to refresh network list, it finds next door's router, but not ours.
So i'm having to plug my laptop directly into the router, which is well inconvenient because it's in the hallway.
Any ideas why this could be? Seems really strange to me.
Sorry if this should be in software, didn't really know which it fitted under.
EDIT: Forgot to add, my laptop is running Windows XP Professional SP2, and my router is a "3Com 3CRWDR100A-72"
