It is wise to be in the latest firmware. You
could either do a remote update if you have a working internet in the MOFI router by going to System and then remote update and perform remote update. If
you want to do a manual upgrade (if you do not have a working internet in the MOFI
router), follow this video tutorial: www.youtube.com/watch?v=7g8SGYDNVbw
At this point make sure the SIM is inside the
router. Now log into the router and go to Network and then MOFI internal modem
and then all the way to the bottom of the page click on Press here to reset the
Sierra module. Once the router is up, perform a factory default. The internet
should work automatically. If not, make sure the APN you are seeing is fast.t-mobile.com.
You can check APN from MOFI Internal Modem, all the way to the bottom of the
page you should see your current Access Point. If we are good on that side, go
ahead and check your signal strength. Go to Overview from the top left hand
corner on the list. On the middle of the page, click on Check Signal Strength.
If the signal isn’t good enough, you can try
to perform band lock as well. To perform band lock, follow the instruction
LTE bands are 2, 4, 12/17 and 71.
Please follow the instructions to perform Band
Lock on MOFI4500 router :
• Log into the router
• Go to MOFI Internal modem and below that go
to Band lock
• On the right-hand side you should be able to
see Lock Modem to a Band and then select Band 2 from the list.
• Click next and then finish in the next
• The router will go through a power cycle.
Once it is up your router will be locked to Band 2. Run at least three-speed
tests if you have internet light on and note it down.
Repeat the same process for Band 2, 4, 12/17
and 71. Then finally lock on to the band that gives you the best results.
NOTE: If you do not see internet light for one
specific band, then either the signal is really poor for that band or that very band isn't offered in your location
