NR7101 connection issues after update module to R13A02

Toniospritz

Hi, i've update in DFOTA mode the cellular module but i have some connectivity issues. Before the update, in auto mode, the connection was optimal, but now i must have enabled the PCI 4G LOCK on the b20 band for establish the connection. I've check the connected band and i not see the B7 (i read only the B20, B1, B3 and N78).
i would like come back to the RG502QEAAAR11A07M4G for a new test. how can i downgrade?

Thanks

Antonio

Anyone have had similar problem? I've tried different configuration but my uplink is everytime very slow, <1Mb/sec

Tried to do a properly factory reset with a pin on your unit?

Hi Selberg, yes, i've tried. My impression as that the module has less power.

Did you use the same Sim card in the same place with other device to cross check?

I not have other devices for test.

Use your phone, put your sim in it if you got one?😀

ahhh, yes! I've used my phone with same operator sim. I read the band 7 but is not stable, sometime disappear.

This means that the signal strength of band 7 is too weak.
Can you share the average speed before you upgrade module and after you upgrade module?
Is using PCI lock on B20 increase the performance or not?
