Cannot connect to web sites over wireless, but can over wire.

[jtpr]

I have a system in the office that has a wireless connection and a
wired connection. If I connect only over the wireless, I cannot get
to web pages. I can send and receive email, but no web pages. Plug
the wire in and all is fine. There is one DHCP server, a sonicwall,
and both connections are configured for DHCP. I can connect to this
system remotely when only on wireless. It seems that only HTTP is
affected. I can ping web sites by name and they resolve. Other
people using this same wireless connection (Linksys WAP54g) work
fine. I have tried power cycling the WAP to no avail. Both wired and
wireless point to the same gateway/DNS servers. The systems local MS
firewall is off.

Any ideas?

Jack,

Thank you. I went through it but no luck. This is driving me nuts.
I can connect to web sites on the LAN, but not outside.

Since this seems to be in an "office" environment, you may need to
contact the IP department. Several "business" grade wireless routers
can be configured with the wireless and wired "network" as separate
networks, with their own access rules. It seems that the wireless
network is limited to email access.

Thanks, but the bad new is I AM the IT department:+}. No, this is a
basic Linksys WAP, no bells or whistles. Another rep came back from
the road yesterday and his laptop works fine. It seems to just be
affecting this one machine.
