When mine does that, I power down the router and start it up again.

Hi. I recently jumped into the wireless world (got a Compaq 3045US with a built-in 802.11g wireless adapter, running Windows XP Home). My generous landlord (upstairs from me) has allowed me to partake of his Internet service (via a Linksys router). Last week, I had no trouble whatsoever connecting to his network & surfed the Web easily. For some reason, however, this week I'm not able to access the Internet. I'm still connected to the network (gives an IP address and all), but no Net (packets are being Sent, but none Received). Is there a setting that needs changing on my end?
