I have two PCs, desktop and laptop, using different wireless hardware to access my wireless ADSL modem/router. Both have been working flawlessly for months. Both are running Vista. On Saturday, after applying a bunch of updates, the desktop lost the ability to connect properly to the router. Moving some stuff around let me hook the machine up via cable, which worked (and is still working) just fine.
This evening, the laptop started to do the same thing, having been behaving normally via wired connection until then. It appears to have applied one or more updates yesterday afternoon (although it was still working wirelessly until several hours past that time).
I'm writing this on my old WinXP Tablet PC, which still seems happy to connect to the router.
Is there a possibility that whatever Vista has been updating (probably not SP2, btw, since the desktop has that and the laptop doesn't yet) has somehow messed up wireless connection ability?
Security is WEP, key hasn't changed AFAICT - it's still the same on this machine, for example.
(I'm planning on taking everything up to Win7 soon, but there's a few weeks to go yet...)
