Problem with wireless connection

[Atvar]

For some reason since I formatted my computer, everytime I boot I have to disable and enable my wireless connection to get an ip addy from my router. It does connect when I boot, but won't let me get online for some reason. I know that a while ago I did something to fix this but for the life of me I can't remember what. Any suggestions would help. Thanks

Try deleting the connection and uninstalling your wireless card from device manager and start afresh.
