I can start over at the factory reset, but nothing changes.
Firmware is: 2.271
So what am i doung wrong here?
Saw that there is a new FW v3.001-20180821
Flashed with “keep settings”
Is the APN thing addressed in this version? If so, i still have no option to set the APN.
After entering 3 chars the field is cleared. and “the circle keeps spinning”
No problem. As my mifi has no purpose atm because of these connection problems, I am thankful that you keep an eye on this.
Unfortunately 0823 didn’t change anything. I still cannot configure the APN and the circle next to the input field keeps spinning and resetting everything that I enter in that field.
It seems that the input field is buggy on MS Edge for Android. (Windows not tested yet).
I used Chrome and i could enter the APN.
After a modem reset i got a connection on /dev/ttyUSB3 but the connection speed is at 10% of my Huawei MIFI.
Am i using the wrond tty? Is there a way to boost the 4G signal? At the same spot the huawei mifi has 3/5 bars 4G and the GL-MIFi has 3/4 bars 3G. I’m using the hauwei mifi without external antennas.
You can try to force the setting to 4G only mode,Execute the command AT+QCFG=“nwscanmode”,3
Execute the command AT+QCFG=“nwscanmode”,0 revert to automatic mode
Thanks, that worked well. No my Huawei and may mifi are up on pat… in terms of delivered bandwidth. Is there a way to improve the signal strength for the mifi? My phone is about 5 times faster than the mifi and the Huawei.
