I've discovered today a disturbing drop in call quality on my VFX line.  In the past, it's been a bit sketchy when talking and downloading at the same time, but I'm having problems even when all computers are switched off, and all wifi devices are disconnected.

What it's doing is when you make a call, the ringing tone is "wobbly", rather than a clear, solid sound.  And when the call connects, the other person's voice is similarly quavery, and sometimes slows down.  The other person can sometimes hear me, sometimes not, and I think my voice is delayed, but it's hard to be sure.

Equipment wise, I'm using the Linksys WAG54GP2v2, a run-of-the-mill cordless phone connected to the router.  I've tested it with a corded phone, and it's the same problem, which would rule out the phone itself.  I'm not sure which firmware version it's running, though I've had it about 3-years and don't recall ever updating the firmware.

Has anyone heard of these kinds of problems, and is there a simple fix?  If it's modem/router related, I've been thinking of replacing it for a wireless-n device - is there such a thing with the ATA for VFX, or would I need to get a modem with ATA, and a router with wireless-n?

Cheers
