Have a new x750v2 with latest firmware. I am unable to establish a 4G connection with AT&T (in the US). It will only connect at 3G. Att support can’t help; they say the data plan is active and configured properly. They also told me the X750 is not compatible with their network.
Judging from recent reviews on Amazon, this is a serious problem with AT&T. Do you have a fix for this? I am still within the return window for this purchase, so I would appreciate a response quickly.
4G signal with my cellphone is usable, but not great. 2 bars.
In the X750 gui, there is a section called “Cells info”. Here is somethng I got while it was locked to scanning LTE only (with the AT command you provided). I believe this contains signal strength info:
cellid XXXXXXX (censored)
It went through several cell bands, this is the only one I copied. For reference, my cell phone connects on band 12.
My phone is an unlocked at&t phone whch connects on band 12. My current cell phone plan is an AT&T MVNO but my previous plan was with AT&T directly. I’m fairly certain I am not out of AT&T’s LTE coverage area.
So to summarize, you know of this problem and are unwilling or unable to fix it. But you still advertize this router as “AT&T certified” which is now a completely meaningless and borderline fraudlent claim.
Thank you for wasting my money and time. I don’t know why I expected anything different these days.
For anyone finding this via google, The plan I am trying to use is AT&T’s 100GB/$55usd prepaid data plan bought directly from AT&T. A fully legitimate plan meant for devices like the x750. And this is not some obscure plan; it is one of the primary plans offered for AT&T prepaid service.
I can also confirm that I am experiencing the same problem with my X750 on Cricket, which uses the AT&T network. I have 5 lines on a family plan with one of the SIM’s being in this router. All phones in the house connect to LTE just fine, but the router never does (only 3G/4G, which limits speed to 3MB/s). When taking the SIM card out of the router and putting it in a phone, it connects to LTE with no issues. There appears to be some compatibility issues with the X750 and the ATT network currently.
For those coming here from a google search: I’ve done some more research and found this:
The x750 may be caught up in AT&T’s phase out of all 3G service. If so, than this situation is permanent. The x750 will no longer be able to connec to ATT at 4G, and in Feb 2022 it won’t be able to make any connection at all.
