connects to tower but no internet

[wayne]

Hi. I have a WE826 T-2 and an MC 7455 with a Sprint sim. It works fine, except at home. Here, it looks as if it connects, but I have not internet. Please tell me what may be wrong. Thanks.

Troubleshooting starts with running the following command to looks at the signals and then post the reply:

Code: Select all

AT!GSTATUS?

If I were to guess, you have a U.FL pigtail connector that has popped off the AUX port on the modem, or, it is connected to the GPS port as opposed to the AUX.

Notice above, the PCC (primary carrier) RxM represents the signals received on the MAIN antenna connector on the modem. Notice its RSRP reading of -117.

Next, look at the PCC RxD which represents the signals received on the AUX (diversity) antenna connector on the modem. Notice its reading of -140.

The RxM and RxD should be close to one another. We can also see the disparity on the SCC (secondary carrier) RxM and RxD.

Thanks. I checked and the connections seem to be correct. I disconnected them and then reconnected. Still a connection but no internet. Here is what I get now when I run the command again:

OK


Thanks much!

You have something going on with the AUX connector port on the modem.

Try swapping sides with the 4G/LTE Antennas, and run the command once again.

Also, check the pigtail cable to make sure it did not get cut while reassembling the router cases. They are bad about getting caught between the case and LED's.
