wireless broadband problem

[colandsuey]

I hope someone can help me please with this frustrating problem!

I bought a BT Voyager 2091 wireless router and installed it following the instructions. I also bought a 802.11g USB wireless adapter for my PC and installed the driver.

The router seems to be working fine because I can connect to broadband from my laptop, when I enter the WEP encryption key. Also, when I try to connect to broadband from my PC, everything seems fine - the wireless adapter software tells me that I'm connected.

BUT when I try to go to my internet homepage, it won't open, and my emails won't download. So my PC seems to be connected to broadband but Internet Explorer and Outlook won't download any data - infuriating1

Then I discovered that the wireless connection DOES work if I close Zone Alarm! With it off, I can use my IE to surf and my OE to get emails. As soon as I put ZA back on, my IE and OE stop working.

So I uninstalled Zone Alarm and downloaded and installed a different firewall. But I still have the same problem � the IE and OE work fine if I close the firewall. As soon as I put it back on, my IE and OE stop working.

Has anyone perhaps encountered the same problem and found a solution?

Isn't technology great! I've just had a similar problem with a different router. Network sinal fine, but unable to access the internet wirelessly! Originally I thought that it was the firewall on my laptop, although it still wouldn't work even after I'd disabled it. It will only work if I take the encryption off completely (I've tried all the different options). To make it as secure as possible I've activated the wireless MAC address filter on the interface with the router and entered the MAC addresses of the two PC's in the house, so that even though there's no encryption on the network, only these two PC's can use the connection. I don't know if any of this will be any use to you, but it's made mine work, so it could work for you too!
