Strange DSL connection problem

I have a notebook from my work. It works fine on corporate network, but fails
suddenly on one day to work with my home DSL. My verizon DSL rounter works
fine with my home personal computers (desktop, notebooks). When I connect my
work notebook to my home DSL via cable or wireless, my work notebook (DELL
LATITUDE D620, windows xp professional) will not allow me to access webpage.
When I ping a web page address, I receive the IP address back. This seems
to mean the the request gets to DNS.
I have tried to set proxy auto detection on web page internet options, no
proxy setting, ip address release/renew, DNS flush, reset winsock.
The work notebook seems to be able to communicate with verizon DSL router
since it receives assigned IP address, gateway etc., but fail to allow me to
see web page. I got the same web page you will get if you unplug your
network cable from your computer, then try to access a website.

It seems that the DNS server entries are set permanately in the TCP/IP
settings for the office network. This would indicate that the
"corporate" network settings are directly entered into the notebook's
TCP/IP settings. You would need to discuss with the "corporate"
network technical support dept. in order to get the settings "changed"
so that you can move to laptop "around" to your various networks.
 
There is no hard coded IP address, or DNS address on IP property page. It
obtains IP and DNS address automatically.

Other possible causes:

1) Your "corporate" network user account "type" does not permit the
network TCP/IP settings to change. This is usually caused by seting
up the user type to a non-administrator / non-power user type.

2) Wireless signal mix up. There are 4 different wireless signals
and one is not "directly" compatible with the other signals.
802.11a
802.11b
802.11g
802.11n

Signals for 11a will only work with other 11a devices (unless the
device has the 11a signals.) 802.11n, 802.11g and 802.11b all work at
the same singal level and most devices will connect to the lower
802.11 signals.
