Hey C:Amie,
What is ppp_conn_fix.cab and is there a MIPS version?
No, I'm not the original poster, just have a similar situation with a NEC MP790 with a Microsoft MN-520 wireless PC Card using generic Intersil Prism drivers.
I can ping everyone in the LAN and the internet, but I can't open the router's admin page, can't open any web page in PIE, can't RDP even after opening port 3389.
The router is a Netgear WGT624, if that helps.
I've tried most patches and fixes found in the forums, but no luck yet.
I'm thinking maybe i can try ppp_con_fix.cab if there's a MIPS version?
