I've been an owner of the v1 version of the WRT54GX as well as several other Linksys routers. My WRT54GX V1 that I've been using recently stopped powering on, so I opened a warranty claim with Linksys and they sent me the newest version (v2) of the WRT54GX. I was pretty happy to get the latest version with the removable antennas. I flashed the firmware to the latest version 2.00.8 and removed my Netgear router I was using as a replacement when my original v1 WRT54GX crapped out. Everything is good until I try to start using my VoIP phone and none of my calls will go out, and I get fast busy for everything including trying to call my provider using 611. I let it go for a day thinking my provider is having problems. I finally think that maybe it's the router, and swap my old Netgear back in, and then the phone works fine. ??? I've never had to put my VoIP adapter in the DMZ or open ports, but I figure just for troubleshooting I'll put this new Linksys back in and try to put my VoIP adapter in the DMZ and then try to open the SIP ports if that doesn't work. Well none of these things work. I didn't really expect them to because I've never had to do that with my previous 3 or 4 Linksys routers, and never had a problem with my Netgear router. Anyway... I sent an email off to Linksys telling them my situation and what I've done to troubleshoot. They finally answer me back and said I'm the only person reporting this problem and they would check it out in the lab. I haven't heard from them for about a week. I was just wondering if anyone else has the latest v2 version and has tried using VoIP thru their router.
