Have an intermittent networking problem. Dell 1.7 GH running Win XP Pro. Ethernet connection to Linksys befw11s4 ver 1 then to Cox cable modem. Usually for 4-5 hours I have normal connection to the Internet via IE 6 and OE 6. Then I lose connectivity. However, other PCs connected to the Linksys via wireless are UNAFFECTED. Problems noticed in 2 ways: 1) IE browser fails. Cannot even access the Linksys router control page, accessed by IP address. But can ping the router. Also can ping my DNS servers at Cox on the network. Cannot access web sites by entering IP addresses. Error at bottom of error page is "Cannot find server or DNS error" 2) OE Express cannot check for new messages. "TCP/IP error occurred while trying to connect to the server. Account: xxxxx Server. 'pop.central.cox.net' Protocol POP3 Port 110 Secure(SSL): No, Error Number 0x800CCC15" But I can ping cox.central.cox.net. If I disable the network device via Windows and re-enable it no change. If I log off the user and log back on, everything starts working again and will for several hours. When I have the problem, run a IPCONFIG /all and compare to the same command from when it is working fine - no differences noted. When this happens I still have access to other computers on the wireless to access their files. Happened when I was doing a file transfer which was not affected. Recently updated the Ethernet driver. Recently removed the McAfee firewall software. Also switched router ports - no change.

Hi there, Interesting problem you've got there! Good to see that you've done some initial problem determination too! A couple of questions : Are you using static IP or DHCP? Are errors being cut to the event viewer at the time of the problem? Have you tried removing and reinstalling your TCP/IP stack? I've seen strange problems like this occur before it may be a DLL has been slightly corrupted which causes this odd activity. Cheers, James.

Using DHCP provided by my LInksys router. "Event viewer"?? not sure. When using OE, I get an error box when I try to send/receive messages. For IE, I get the failure screen with the message at the very bottom. I had read the advice about removing and reinstalling the TCP/IP stack. But also read you cannot do that with XP. Latest: WinsockXPfix did not solve it. Neither did removing firewall software, antivirus software and various other software. However, when restoring the virus software, found I had a trojan - backdoor.hackarmy Resolved it easily. Not sure how long it was there. Hopefully only got it while operating the PC without the firewall/antivirus software. Have hardwired another PC - a laptop with Windows xp home - to my router. Generally the problems occur within 4 hours of booting. So far, this laptop has operated for 7-1/2 hours without any problem connecting to the network. So... that pretty much rules out the router. Wierd problem. Just often enough to be irritating. Bob

My problem appears to be resolved. It appears to have been caused by the backdoor.hackarmy trojan. I didn't have it at my backup 11-28-2004. Can't tell exactly when I got it. Was using a different antivirus. Now using the AVG free edition which found the trojan. Bob
