Connection problems

[slid_away]

Hi All
I am running Windows 7 and all has been good so far. This last week though, everythime I start up my PC it does not want to connect to my router.
It does say it connected to my router but I can not get on the internet. After running the diagnostic wizard it fails to connect, I have to retry a few times and always says something about the IP address but eventually does connect.
Does anyone have a soloution please?
Cheers

Yep, thats all we need to know: it "always says something about the IP address ".
It amazes me the number of people on here who expect other to go out of their way to help them, but just can't be bothered to supply all the relevant information.
