{mosgoogle}VoIP Performance

Setting up the Linksys WRT54GP2A-AT was no harder than setting up any other Linksys routers. Just plug in everything to it's corresponding port, then fire up Firefox (or Internet Explorer) and log into the router to set it up. Total setup time is about 10 minutes.

Because the WRT54GP2A-AT is tied to AT&T’s VoIP service, AT&T locks certain parts of the router’s firmware to prevent you from flashing it so you can use it with other VoIP providers. We also found you can not disable the firewall (but you can set up DMZs) and the QOS settings are locked as well.

VoIP phone calls were amazingly good. Call quality was super clear and free of any background noise or echoes. Even when the router was downloading a bunch of files off the internet, voice quality never dropped. I have lost connections before with stand alone VoIP phone adapters and separate routers when uploading files and talking at the same time. That never happen with the Linksys WRT54GP2A-AT. This is by far the best VoIP adapter I have ever experienced.

Router Performance & Conclusion

Router performance was equally as good as the VoIP performance. The WRT54GP2A-AT is among the fastest wireless router I ever tested, just a tick behind the D-Link DI-624. With my notebook right next to the Linksys router, I measure 37.8 Mbit per second transfer speed, dropping to 37Mbit/sec when I moved 5 feet away. At a distance of 50 feet, wireless speed dropped to a still very acceptable 17.5Mbit/sec.

Going into this review, I really thought a separate router and VoIP adapter was a better way to go than the Linksys WRT54GP2A-AT. However, after experiencing the amazing voice quality offered by Linksys QOS feature, I wouldn't use a stand alone VoIP adapter again. Add in the fact that the Linksys WRT54GP2A-AT is also among the fastest wireless G broadband router you have yourself a winner.
