After a search on google for no blue light on my WRTU54G-TM Wireless-G Broadband Router with 2 Phone Ports, it brought me here. I tried everything everyone suggested but nothing worked. But it did make me feel better I was not alone. Anyway, after 5 days of being on the phone with countless Tmobile techs my blue light came on. So I am here to share how I got it working...it took no router reconfigurations.
Like I said 5 days and countless hours and I finally got it going. First they said it was my router, but I knew this to be false. I had perfect connection to my DSL internet(AT&T), so they sent me a new router. Then they said it was my SIM card..so off to the locale Tmobile store I went for a free SIM card replacement. Still no blue light! Oh I forgot to mention...when logged into the router page...status..voice, I was getting the error of SIM not registered. So a trouble ticket was made for me on day 4. On day 5 I called Tmoblie@Home support to see the status of my ticket, because at this time I was really ticked off I had not had a phone for several days. Rachel at Tmobile got me this time. She asked me if I had registered my phone with 911. I told her that I had already checked that with another tech 2 days earlier, by signing into my tmobile account and verifying that my address was there under my home phone number. She then asked me did you physically register it. I said No...No one told me too. Not the box the router came in...not the CD for easy installation...not any of the other techs I had spoke to for the past week! So she told me to go to Tmobile.com and register...I rolled my eyes and followed her directions...pretty much certain I was doing this in vain. Well I got the dang blue light! Yep...came right on after I followed her directions. So, I asked her...why didn't anyone else have me do this..her response, it says on the box the router came in, that you have to do it. I told her...No it doesn't. Even the set up CD says a rep from Tmobile will set up 911. Didn't want to argue with her any further...since she was the one to get my blue light on. So I thanked her and I have been happy every since.
So below are the steps you might want to try if you are having this problem.
NO BLUE LIGHT...error SIM NOT REGISTERED(even though Tmobile says it is)
1)Go to www.tmobile.com
2)Click register(even if you already have an account, pretend you don't)
3)Enter your tmobile@home phone number..hit submit From there it will reconize the number as a Tmobile@home # and ask for a cell phone # associated with the account so it can text you a 6 digit passcode. 4)Put in your cell phone number..submit Passcode should be sent to your cell immediately.
5)Enter passcode on tmobile site..hit submit
6)From here it will bring you to your MyTmobile account/profile 911 page. Verify the that the address is correct for 911. Then you must hit UPDATE on that page...even if you didn't change a thing. Then power cycle the modem and the router. After waiting about 30 secounds reconnect the power to your modem...I had to wait for my DSL light to remain steady about 30 seconds, then reconnect the power to your Tmobile router.
Wait for internet to connect. I then went back to the router page...STATUS...VOICE and refreshed it. Wahlaaa...Blue light went on and SIM Registered.
Hope this helps someone.
