Wifi doesn't detect networks - X Play Q&A, Help & Troubleshooting

My phone doesn't detect any of my wifi modem networks but it's able to detect the mobile hotspot generated from another phone. I tried factory reset as well as flashing the firmware but no luck. Please help me on this.

Galaxy Tab not recognized by CDMA WS, QPST or QDXM but....

....in device manager the diag drivers and the port show up fine. I can connect with Odin in recovery and connect through ADB. I have another Tab (same model) and connects fine. Kies is installed and activated modem in diag screen and toggled. I uninstalled the drivers, wiped it back to factory and reinstalled the drivers and tried to connect again, but no luck. I can also read the sd card as well. Any ideas?
Reading some more...
....in other posts similar (which have no conclusions) it appears net.cdma.configurable.mode is set to "-1" and needs to be set to "1". Anyone know how this can be done?
a little more history into this issue; it happened after an meid repair and after I rebooted tab, were it once connected....it never did again. Anyone? Any clues or have i figured out a way to permanently turn this tab into a wifi only model?

try disabling your wLAN security and try again
Have you tried factory reset ?
I think that the factory reset would solve the problem
Go into recovery and erase data, cache and dalvik-cache.
That will hopefully fix it
If not, try turning bluetooth on then using wifi

I can't connect device via qpst

To summarize when I put it in diag it connects and disconnects very quickly in the QPST, showing what it should, then esn 0 and then disconnected device, this flashing all the time, I assume it was after a corrupted .qcn, I wonder if you have some solution for that and that i can recover my imei and wlan.
Here what happened to get to this problem: my Chinese note 7 had a problem, I had to reset via edl for verified account and then unlocked the bootloader. Since the time I needed edl verified it has returned without wifi and without imei. I had managed to recover the wifi but imei it not through QPST, until I used it again and the cell phone went to Orangefox direct. I tried a new one. Qsn but the computer gave a problem, I ran out of backups and I can't connect anymore, always flashing between connected and disconnected devices, from time to time appearing what should be quickly.

TB-X505F (Lenovo Tab M10), could not activate wifi and bluetooth any more

Hello,
I have a TB-X505F (Lenovo Tab M10) with the stock ROM TB_X505F_S001149_221115_ROW.
It is rooted and I tried different Magsiks/Zygisk modules.
From one moment to the next, WLAN and BT can no longer be activated. If you move the slider for turning on WLAN to the right, it jumps back to off a few seconds later; the same with BT.
What I have already done:
- Reset network settings via Settings -> System
- Factory reset via Android
- Factory reset via TWRP
- Factory reset via StockRom recovery
- reinstalled the rom with LRSA.
- Reboot with and without SD card
Do you have any idea what that could be or what else I could try?
With a cellphone module I read that an IMEI can get lost and that the module can no longer connect to the cellphone network.
Is there something like that with the MAC address of the Wifi and BT interface?
Thanks.
