I am also having problems!! I just bought a Compaq Presario laptop with wireless capabilities.

However, at least 3 times daily I have to turn it off, turn the modem off etc and the wireless router and then restart them all because it switches to local only or "limited connectivity".

We have a Belkin wireless router and I am also not thinking about getting an extension to our data cable to plug into the internet. I am so frustrated with this. It is such a waste of time and money.
