Lost wireless network connection on laptop

[Walter Cohen]

My son had his Dell laptop at college and was using their wireless network
successfully. He came home last week and tried using his laptop on our home
wireless network (w/Linksys router). He said he was not able to always
connect so he tried to set up (configure, repair) the wireless connection
himself (always a dangerous thing to do).
Now he gets no internet at all (IE always goes into 'offline' mode).

I've tried to trouble shoot the connection but so far I have been
unsuccessful.
The laptop can see the wireless network (it shows as available and
connected).
There is something wrong with the network connection that IE uses but I
don't know how to go about fixing it.

In the laptop's Network Connections I see 'Lan or High-Speed Connections'
with a 'Wireless Network Connection' of connected,firewalled. Also, in the
configuration area under connection properties there is (checked) Client for
Microsoft Networks, File and Printer Sharing, QoS Packet Scheduler, and
TCP/IP. There are other services unchecked such as Client Service for
Netware, NW Link IPX/SPX, NW Link Net Bios, AEGIS Protocol, WLAN Trans...
(some/all of these I'm thinking were added for his university connection).

Can someone please help me. What can I do?

Thanks,
Walter

Under the TCP\IP properties is it setup to abtain a ip automatically.
Obtain DNS server address autmatically.
