Thought I’d post this little technical issue to my blog in hopes that someone else in the world has had the same issue I’m having right now and perhaps share their solution

I have a Linksys PAP2 VoIP adapter (Firmware version 1.00.22) plugged into an Ethernet port on my Airport Extreme (Gig-E). I also have another Airport Extreme setup as a repeater in my home theater.

When I use my VoIP phone, my wireless clients internet connectivity slow to a crawl. While doing a ping to my gateway (10.0.1.1) I can see my response times become pretty erratic ranging form 50ms to 1600ms, with about 15% of the requests timeout.

I setup the PAP2 VoIP device with a static IP (10.0.1.5) and set it as the default host. My theory at the time was that since it was being NAT’d, the inbound UDP traffic was being transmitted across and flooding my wireless network.

This doesn’t seem to have fixed the problem. I experience this wireless slowdown on both my PC (Dell Precision laptop) and my Mac (PowerBook, MacBook) wireless clients.

Both my AirPort Extreme base stations are running the latest version of the firmware (7.2.1, I believe) and this issue does not happen to wired clients on my primary base station (where the PAP2 is plugged in).

Has anyone else experienced this problem or have any idea what could be happening? I’m hoping I’ll be able to locate a solution somewhere, but so far I haven’t found any resources online that would help.

Thanks!
