T48G Registers Successfully, Then Later Fails
I have 3 Yealink T48G units connected via wireless dongles to a series of 4 Apple Airport Extreme Wireless Access Points. All work flawlessly and register successfully.

I have added a 4th Yealink T48G and this is where the problem started.

When I initially plug in the wireless dongle to Yealink #4, the phone searches for the WAP and connects (although, for some reason, it always connects to a weaker signal WAP, so I manually disconnect and reconnect to the closer WAP).

Then, the phone registers, shows green, and I can even place a test phone call. Then, about 1 hour later, the phone goes into screensaver mode (doubtful that has anything to do with it), and when I check the phone, it shows gray icon and fails to register.

In order to make the phone register successfully again, I have to switch wireless dongles from Yealink #4 with Yealink #3, and then - both Yealinks successfully register. I can make a test phone call on both phones. And then, 1 hour later - the same problem. Although sometimes, Yealink #3 is the unit that won't register.

Thinking that the dongle could be the problem, I ordered a new one. And the problem persists just the same. It almost seems like my voip provider is only allowing 3 phones to be registered at once (is that even possible)?. I thought I could troubleshoot this, but I am stumped and hope someone on this forum would be so kind as to offer some assistance or has had a similar experience.

Thanks in advance. Any help would be greatly appreciated.
