Have set up my linksys wireless router and PCI cards fine. Most of the time I have no problem connecting. But certain sites disconnect me (eg my bank and also when I try updating AV/firewall software). I've got McAfee AV/firewall and my brother also has the same setup - we both have the same problem (although he's using Netgear equipment).
Just wondered if anyone knew of any issues with using McAfee?
