Re: Latitude E6400, Intel Wifi Link 5300 AGN Drops Connections
I had exactly the same problem as you describe. I tried a number of things to resolve it without success - wireless adapter power adjustments, roaming adjustments, wireless adapter de-install/re-install, Linksys WRT54G firmware upgrade, TCP/IP reset, etc.
Finally, I resolved the problem by disabling my WEP encryption. Apparently, there is some incompatibility between the Intel Wifi Link 5300 AGN adapter and my Linksys WRT54G router relative to WEP encryption. Currently, encryption is disabled, but I plan to try other encryption modes (e.g. WPA) to secure my wireless network.
