Wireless Lan Problems

When I first installed the Linksys 802.11b wireless router and 3 wireless ports, everything worked like a charm -- for 2 months. They I downloaded and installed a firewall (McAfee) and ruined everything to the point that I think I will dump the wireless and go to wired. Here is the problem.

I conntec my cable modem to the Linksys router. The computer that is hard wired to the router works fine, but my computer, which is wireless, does not work. The Linksys software says "You are connected to the network but the internet cannot be found."

I disabled and uninstalled the firewall -- no change. I can ping www.linksys.com, I can ping the routher, but I cannot connect to the internet using IE. It seems something is blocking me from accessing the internet, but I can't figure out what. Over the last several days I've spent nearly 4 hours on the phone with Linksys and they finally gave up. Any of you have any ideas?

If you can ping LinkSys and the router, then you are connected and have a route to the internet.

It sounds like some settings in the computer have been changed (possibly in IE?) I would try uninstalling IE completely and do a fresh install of it. Try uninstalling the wireless card (make sure you remove it from the Device Manager) then reinstall it exactly as the instructions recommend - if it's USB, plug it in after the computer is up and running, etc. Basically, the idea is to get all of the settings back to their defaults (pre-McAfee install.)

Try that and let's see how it goes.

Technically, this is a problem with settings somewhere. As Safewatch said, if you can ping an internet site, you have a path. If it worked before McAfee, it will work. You should try to return to the pre-McAfee state.

Hope this helps.

About configuring Mcafee firewall 3:

Uninstall for xp:
Uninstall for win2k:
Uninstall for ME and 9x:

A main page for mcafee products/problems. I don't know your os or your mcafee version. It may be that it didnt fully uninstall, or some ie settings may need to be changed. This page(scroll down to your version of firewall) should be of some help.

or here:
