very, very strange wireless network problem

Two computers - both XP both getting on line wireless - one
desktop and one laptop.

The desktop doesn't have a problem.

The laptop can't connect to google or a home page. I reformatted
the laptop and reloaded XP Pro (did the slow reformat). Same problem
still exists. It's a Toshiba Satellite and a Netgear RangeMax NEXTY
Wireless-N
Router connected to Comcast cable modem (Motorola - New).

The strange thing is that the laptop will not connect to google or a home
web page.
The only strange thing I notice is that in Control Panel, Network
Connections, is that
there is a Internet Gateway showing. I didn't install that.

When I disabled the Internet Gateway connection, the wireless wouldn't work.

I brought the laptop home to work on my network (PPPoE DSL) with Netgear
RangeMax
router. It works on my network. (Even when I disable the Internet Gateway
connection).

Any ideas???

 

It more than likely doesn't have the IP/DNS address info for one of the
network connectons. Go to the start menu, open Run and type cmd. When the
window opens type ipconfig/release. Then type ipconfig/renew. That should
fix the problem. I had a similar problem when I took a laptop to work and
it wouldn't connect. It was still trying to connect to my home ISP, which
wouldn't work. I needed to release and renew the network connection to get
the new ISP settings to work.

I have already tried this - thanks.
