Losing signal after updating CM

Hello there,
I installed the latest CM from the official website and now I have problems with my signal.
Most of the times, the phone can not find a signal. Sometimes it catches it, but it will last for 4-5 minutes. If I go into flight mode and come back, the signal will be there for 1 minute. When I don't have signal, there's the R near the signal bar (Roaming).
I haven't changed my modem with the new installation (I9505XXUAMDC). I am on the O2 / TESCO Mobile network in Ireland.

Hi mate ,
I assume you have an I9505 , there is know issue with modem/bootloader incompatibility you may have to use a modem wifi fix or upgrade the bootloader to use the newer modems

Should I install only the modem or the Wi-Fi fix aswell (with the combined package)?

Hi mate ,
If i am not wrong that is a 4.2.2 modem , if you don't worry about the warranty anymore i would get the full package
MODEM / LTE / BOOTLOADER
I fixed it by installing the modem+Wi-Fi fix. I was afraid of installing the bootloader, as if something goes wrong when installing the modem, it can be fixed, but I don't think it's the same with the bootloader

Lost Signal after Lollipop update

Hi guys
My phone was rooted but never flashed a ROM on it. Today I updated my phone to Lollipop through Kies Mac. After that my signal is not there. When I reboot the phone I get signal for few seconds then it gets lost again. Also phone never saves my Wi-fi connections.
I did reset my phone but still the same.
It was locked to Vodafone and I unlocked it in Vodafone shop when I first bought it do you think anything related to that?
How can I downgrade to KitKat or get my signal working?
Same here. Do any of you guys know how to solve this issue?

Please use the search function of this site and google, don't be lazy. There is a thread about downgrading . Also try flashing lollipop modem/bootloader, for this visit any of the TouchWiz Lollipop rom threads (like the one in my signature) most of them talk about flashing modems and bls.

[Q] I9505. No signal when using 3G/4G. 2G works

Hi.
After updating Danvh's lolipop-rom to the latest version, I lost my signal and wifi. When I force my phone to use 2G (GSM only) in network-settings, everyting works normal.
But of cource I want the speed of 3G and 4G when using internet!
Sometimes (not often) 3G works.
Sometimes the phone says it has signal, but calls, internett etc don't work
I tried to flash the latest modem (XXUHOC6), but no luck. Have also tried modem XXUGNK4, XXUHOB8 and XXUHOB7. I tried to go back to the older version of the custom rom, but no luck
I have now downloaded the latest official stock rom from sammobile. But same problem with stock rom.
Any suggestions?
I have IMEI
Sorry, I have the same problem and I am still searching for a solution. And I have been trying everything as you and no solution. Sometimes I think is a hardware issue.
Very frustrating :S
Hope to find a solution soon.
I dont want to buy a new phone yet. There is no other phones out there that I want

WiFi connections problems - baseband?

Hello,
since I installed Nougat to my G4 Plus, first stock, then lineageos 14.1, I have problems with the wifi connections... every know and then, it just disconnects. I observed this behavior at many wifis, not just mine at home.
Does someone else have this problem? Which baseband are you using? Are you using dual SIM?
I got the baseband M8952_70030.25.03.62R.
Thanks for your help!

I'll concur with this. On both 2.4 and 5GHz as well as over 4G, my connection will drop every so often.
Nothing life-changing, but somewhat annoying. I'm on the Nougat RETUS radio.

I'm not alone. Fine. Which baseband version are you running on?

Same as yours; 70030.25.03.62R
I also have the same issue since the official Nougat update. Any ideas as to what it could be. Very annoying.
I have the same issue, it's very random and sometimes the wifi will not re-connect, I must manually connect to re-establish it. I have attempted to discover what if anything I am doing which may be causing it to occur with no real answers. I find it more than mildly annoying as it results in my connection timing out. Sometimes I may go hours without an incident, other times it is perpetual and constant. I believe that it may be caused by faulty hardware or firmware for the wifi radio as I have been incapable of discovering any evidence to suggest that this is widespread enough to be related to Nougat. That being said I did not have this problem until completing the official update on my phone which was completely stock at the time it was initially completed. My only course of action at this point is to A. rely on someone far more intelligent with this device to fix it. B. replace it with a different device
Same here. Very annoying when using VOIP etc. I tried both M and N basebands and different roms/kernels.
The problem might be due to the router settings.
Try to update firmware of check your wifi channel.
Wifi connectivity problem after ROM upgrade: baseband VS Llineage VS stock ROM
I flashed the newest clean stock firmware NPJS25.93-14-18 on XT1625
baseband M8952_70030.25.03.62.02R Athene_RetUSA
Then I flashed Llineage-14.1-20180815 and observed problems with Wifi, mostly with old WEP protocol.
Then I downgraded to stock ROM NPJS25.93-14-7-8
baseband M8952_70030.25.03.64.01R Athene_RetUSA.
Wifi connection seemed to be OK on stock NPJS25.93-14-7-8.
So is the wifi problem resolved with baseband M8952_70030.25.03.64.01R?
Not exactly so. After I flashed Llineage-14.1-20180815 with GApps (nano) , the wifi problem re-appeared despite having "good" M8952_70030.25.03.64.01R
So baseband is the same, but Andoid 7.0 stock ROM handles wifi better than the latest Lineage. Or is Google apps and software is involved?
The problem was discussed on Motorola forum
The problems seem not to be limited to Moto G4 only, but clearly appeared after upgrading to newer firmware. It might have something to do with tightening security in resent Android and Google firmware as Wifi WEP protocol considered outdated and of low security . However, some people reported problems with Wifi WPA protocol, too
