Evening all! I have run into this absolutely fabulous little stinker of a problem that has pretty much everyone around me, including me of course, defeated! I have a client which has purchesed three E-Machines G-725's pre-loaded with 7 Home Premium 64bit. I set up all three machines at exactly the same time, in exactly the same way, installed kaspersky workstation 188.8.131.524. Two machines got Office 2007 and one got 2003. I returned the laptops to the client and started the wireless setup. In all three cases not one of them had any problems connecting to the network and internet works. In two of the cases, the laptops would absolutely refuse to connect to any other pc's in the network. After plugging them into the lan it connects to other pc's fine but not on wireless. Also, on one pc I removed kaspersky, after which the problem disappeared. The other one I disabled Kaspersky in startup, which also solved the issue. On the third however, kaspersky is still active and THAT laptop has no problems whatsoever. I cannot begn to think that office is causing this to happen a the laptop that DOES work has the 2003 version while the other two runs 2007. The conspiracy theorist in me just had to bring that up. All three these machines were connected to the wireless network at my office and had no issues in connecting to any segment of our network at any time, WITH kaspersky running. I'm stumped, they're stumped, we're stumped. Anyone ever run into anything like this? If someone could shed light i'll buy you a beer.
