Question : Can connect to wireless network but can't ping

 Hello experts,

    I installed windows xp prof to one of the company computers. When I tried to install Dell Wireless 1450 USB adapter, it worked fine, I was able to connect to office wireless network. Problem is I ca't ping or browse web pages on that computer. I coudn't figure out the reason, any suggestion?

Thanks

Answer : Can connect to wireless network but can't ping

What you have to do is, goto a machine which is working fine, means can ping gateway and access internet, run the same command on that pc, like
ipconfig/all>ipsettings.txt
the result will go to the txt file.  Post that result here

Now, how is your wireless network connected to the LAN(or is going to the isp modem?) ? do u have an Access point only or access point with dhcp?
From your wirelss machine, open IE, tyep http:\\192.168.0.1 see if you can access the wireless router? the ip for this could be different but thats what it normally is.

need some more information to procede
