Vista Dropping My Connection. Microsoft PLEASE ADDRESS!

I've read a lot about people losing connections for no reason. Im told that
its some problem with a router all all that hooy. This happens 2 times a day
once in the afternoon and once at night. It shows im still connected to my
wireless, but internet explorer says unavail. So again I have to reboot.
Which even is more strange if i am using AOL or AIM i still can instant
message, however internet surfing is down...its SOOOOOOOOOOO odd. Ok so now
that I reboot only thing that helps, everything is OK again.. SOMEONE PLEASE
explain this is driving me mad. I dont want to start checkin and unchecknig
IPv6 and all this till I know...Thank you. I hope you read this microsoft
cause this VISTA crap is getting old. Its pretty but thats about all it is.
Did you fix this with ur SP2?

IM using a 2 year old Linksys router, a 1 year old toshiba sat laptop..and i
connect wireless.
