I have been using a Dlink DI-624 router and Dlink DSL 502T modem very succesfully to access broadband internet. During an equipment move I have damaged the power adapter to the DI 624 so have replaced it with a Netgear WGR614 v5 router.
My Dell laptop is running XP Professional up-to-date with latest patches using a WG511v2 PCMCIA network card. Both router and network card are running the latest DLink software available from DLink's Australian support site.
The other Dell laptop is running Vista (Home Edition) up-to-date with latest patches. It uses an internal wireless network interface.
The laptops are both running WPA-PSK (TKIP) encryption and run quite OK for a while. SIgnal strength is high. I set the key lifetime to maxiumum (256 minutes).
Both laptops periodically lose http internet conenction with http. But mail still works so there is some internet connectivity. If I reset my network card the internet http connectivity returns (for a while).
Both laptops are using DHCP to achieve an internet address.
I had tried WEP but had the same problems of browsers losing connection. Both Firefox and Internet Explorer behave the same.
Losses can occur within minutes or a hour or more.
So in summary both laptops work fine but periodically lose http capability but strangely maintain email capability during http outages. Resetting the PCMCIA card restores the conenction fully.
How do I fix this annoying bug.
