BlackBerry 9780 UMA Problem

[CraigMJamieson]

This is so strange. Up until about a month ago, my UMA worked perfectly then it just stopped. It sees the wifi but will not connect on UMA. Mind you, i have 6 other devices at home that hook to the Wifi perfectly. After a week of going back and forth between Tmob and Century Link DSL I finally went out and bought a new Actiontec Q1000 which is Century Links VDSL modem. Same model i had already. Immediately UMA worked again. A month later it stopped.

Yesterday Century Link came out and after checking out everything we tried another new Q1000. Hooked up right away but only for one day. I have reset the modem, played with every setting I can find on forums, moved the modem, bought a UPS for it, I mean EVERYTHING. Nothing new in the house, I don't live in an apartment, nothing new on my computer or my BlackBerry and the phone will UMA connect to other networks. Still, all my other devices work fine.

What possibly could cause a replacement modem to correct this problem and then why only temporarily?? Thanks in advance for any help you can give me!!

I have to use WiFi at home now because the closest place I can get tower signal is 10 miles away but every now and then my WiFi will quit working on my BB as well. If I turn the WiFi off for a few minutes on my BB then turn it back on it will work fine for a few weeks or a month.

You might try that if you haven't already, it might work for you.

I managed to fix this by going yo the WMM setting om my Q1000 and disabling the power saver mode. This was by pure dumb luck but I have fighting this for probably 45 days. Hope it stiicks!!

This is great. I've been struggling with not being able to connect through UMA at home for a couple of months. It just stopped one day. I've spent hours and hours on the phone with TMobile bb support and CenturyLink with everyone pointing the finger at the other company. I just changed that setting on my Q1000 and my UMA started instantly working. Wow, this has been so frustrating. I can't thank you enough. I would never have figured that out on my own.

What is "WMM"?

It stands for Wi-Fi Multimedia (WMM). I'm not sure if this is a Q1000 (my qwest/centurylink modem) or if all modems have this. It's described as... "WMM is a Quality of Service feature that prioritizes traffic on your wireless network." It was the power saver mode of this that was messing up my UMA connection at home (and the OP's).
