Hi,

I have an adsl wireless router(thomson TG585V8) which is in A-Building  connected to cisco 2960 Switch  and extended to other building B-Building (A-Building Switch Adsl-vlan2  to B-Bilding Switch). From B-Blding 2960 swich Adsl-vlan2 port  connected to cisco 1242 AP. If i connect my laptop to the B-Buiding switch directly i  can browse the "internet".But from the 1242 AP i am able to get 'dchp' i can ping th gateway , i cannot browse the internet. I tried "nslookup" from my laptop ''dns issue". I am attaching the wireless ap config. Please give me an idea for this issue.

Check the following on the laptop

1. The default gateway provided on the TCP/IP adapter of the laptop by the DHCP server is the same when connected to the switch port and the access point ( Check with ipconfig)

2. The DNS server values are also the same. ( ipconfig /all). If the DNS value differs in the wireless scenario, provide the correct DNS server IP address manually on the TCP/IP adapter of the  laptop.

Also please output the result of the t\following tests

ping www.yahoo.com , when connected via access point.

When you issue ping from the laptop
ex: ping yahoo.com

Do you get the IP address on the command prompt

could you display the output when you ping yahoo.com from the laptop (command prompt message)
