Signal (Wifi/LTE) problems with custom ROMs. Maybe baseband? - E 2015 Q&A, Help & Troubleshooting

Hi people... I'm having this problem:
On stock 6.0 rom (XT1527_SURNIA_AMXLA_6.0_MPI24.65-39_cid12_subsidy-DEFAULT_CFC.xml) everything works OK but when i flash a CUSTOM rom have this two cases:
CM13 LTE: I can't even get wifi to work during installation, so i rollback everything
AICP 11 Surnia: Wifi OK, but only 3G network.... Can't get LTE work.
Is this because the baseband? Screenshot next (On AICP rom).

Installed another baseband from 5.1 rom (M8916_2020602.05.03.21.07RFSG) and everything stays the same... Any help?

Hi buddy. I have a similar problem. I installed cm 13 and 4g is not working and signal drops often. Wi-Fi works flawlessly.
I'm on a XT1527 with the same baseband, like you. I'll try with Resurrection remix, someone told me that 4g works on the same phone and baseband but in Canada. Therefore, it must work on Argentina (where I live)
If I flash RR I'll tell you the result. If you find a solution (I didn't) please tell me. Greetings!

I installed RR with no luck. No LTE. I'm going back to stock until is fixed.

[Q] I have poor signal after upgrading to ICS.

After upgrading to stock ICS, I have had awful reception and dropped calls every single day. I have tried with 3 past CM9 versions, with foxhound rom, Checkrom and with 3 or 4 stock ICS roms from samsung.
I have also tried flashing the following modems:

}
the best result I got are on the following stock rom i tried yesterday:
this is in my house, perople have to call me 3 or 4 times before the phone rings.
yerterday at the park, 50 mts from a cell tower, I had 100% signal, perople still had to try and call me 3 or more times before the phone got the call. looks like 100% signal still gives me problems
what else can I do? I have searched and I have done plenty of wipes, I have tried with the phone rooted, unrooted, doing multiple factory resets, installing many different roms and modems. I live in venezuela and have the operator movistar.
I also have a samsung galaxy spica, and I dont get any dropped calls on it.
still have the problem
may b hardware issue

If the signal was fine on GB I guess it is not a hardware issue. Perhaps you need to install more modems in order to manually search the one that will boost your signal OR you can enter the Modems topic and ask there who has the same network as you do and perhaps you'll receive some feedback there.

[Q]No network with CyanogenMod

Hi!
I have a problem with AOSP Roms. Normally I was able to make call but since CM 10.2 came out, I am not.
After flashing CM 10.2, I had no baseband, no IMEI, no network. When I flash stock Rom, it gets fixed. When I return to CM 10.2, i have the same problem.
I flashed today's "cm-10.2-20130828-NIGHTLY-i9300" and now I have IMEI, baseband. But still, I can't make any phone calls.No signal, no network!
I flashed CM 10.2 on XXEMG6 Rom. Is it because of the new format of EFS? Or what?
Thanks!
Berke

I dont have a problem anymore with my Imei. With the new version, it came back. I cant make phone calls only with AOSP roms.
I noticed one thing more. I cant open my SIM lock.

Flash back to stock, turn of SIM lock. Reflash AOSP. I think this is the problem. SIM lock doesn't transfer well between ROM types
Still no network on CM

I tested with many roms (TranzWin , Baidu v53 ,stock and Experience V2, the problem as solved in all with the trick

Kate has no 4g/LTE on any custom roms

Hi, I unlocked my bootloader using the unofficial method.
I have flashed my kate with a Kenzo rom and updated the modem to kate's NON-HLOS.bin.
I am unable to get any LTE/4G signal. When using the official MIUI rom i can get LTE/4G signal.
What am i doing wrong?
I have tried this on:
Nexus Experience ROM
Citrus-CAF
CM 13
XOSP 6.3 Final-mm

I am currently using the rom 'XOSP 6.3 Final-mm'.
Every time i flash a custom rom i do a full wipe then install, and i won't receive LTE/4G
If anytime after that i flash back to MIUI i can get LTE/4G
I had no problem with LTE on Kate (with Fido/Rogers in Canada). The only thing I had to do is edit the APN info because for some reason the default settings were wrong. Once that was done, LTE started working at full speed.
