Need Help-Personal Firewall blocking Wireless Router connections

Hello,

I have a UTStarcom® UT-300R2U Wireless Router, a Dell Laptop with a DW1501 Wireless LAN card and a valid subscription of McAfee (with the latest updates). I am unable to connect to my router wirelessly unless I disable the McAfee firewall and some McAfee Services from the Services applet. I am also not able to ping the router and get a "Destination unreachable" message. When I do an Ipconfig, I can see that the laptop has picked up a default IP (169.254.XX.XX). However if I disable the firewall and some services (see attached screenshot), I am able to connect to my router again.

The  McAfee Firewall blocks incoming connections from the router (like the dhcp server in the router). As the Laptop does not get a IP from the dhcp server in the router, it picks up the default IP, as a result I cannot connect to the internet. I have tried adding the router IP in the safe list in "My Network Connections" section in McAfee, but that does not help.

Can some one please help?

Thanks

Re: Need Help-Personal Firewall blocking Wireless Router connections

Sounds as if the firewall got messed up you should see the router as 192.168 etc.. Actually in the pic above the firewall is still running you have stopped the network agent scanner and proxy service.

I would try to set firewall to defaults and see if network is detected after a reboot. Try setting the ip as a fixed ip for the laptop. I seem to remember wireless issues have you tried wired as a test?

In desperation I would uninstall Mcafee via

http://service.mcafee.com/FAQDocument.aspx?lc=1033&id=TS100507

reboot and run

http://download.mcafee.com/products/licensed/cust_support_patches/Mcpreinstall.exe

then reinstall and see it it helps. I asume the network works as it should when Mcafee not installed and net as well?

I tried your suggestions Peacekeeper, and set the Firewall to default values. The Network is detected and added in "My Network Connections", but it still didnt work. I tried debugging further and see that if I just turn the McAfee Network Agent off, it works and I am able to connect to the router (Everything else is on ). Any ideas? What does the McAfee Network Agent do? If I turn it off, what kind of issues could I face?

Thanks for your help!

Best you try a tech support chat via useful links tab above and see what they can suggest. I assume everything fine with network agent off . that is a starting point with them. Have you tried wired that is what they will ask.
