Replying to Wireless internet problemm help?

so i came home from work a couple days ago
go to connect to my network like i always do
and it says im connected but when i try to view a webpage i get nothing

tried all the troubleshooters
even went and reset my modem and my wireless modem thing.

and in the end the only thing that worked was when i did a system restore to the day before.
so im thinking its all good but now whenever i turn my computer off and then turn it back on the same problem happens and i have to system restore.

so yeah im stumpted.
also my laptop was on the day this started happening when we had a power outage dont know if that might have effected anything.

help is really appreciated.
