NOTE4 - APN settings are not available for this user

I have seen meany forums ignore this one please help.

Device is T-mobile note 4
Rooted - I am using cyanogen mod - (trltexx) trltetmo does not work for my device.
( cm-12.1-20150808-NIGHTLY-trltexx.zip )
I get an MD5 error? but it installs anyway
There is no cellular service.

Everything works except my sim card. It wont detect it and my APN settings page says.
"APN settings are not available for this user"

Things I tried repeatedly as suggested by google searches
I tried each one with a clean rom install

1. - manually input APN settings (it wont save them)
2. - Reboot 5 times
3. - Remove the sim card before first boot
4. - Use wifi first to "warm up network"
5.- Wait 3 days for cellular tower to send me signal
6. - Wait 5 min
7. - Try a different rom (same problem with apn settings)
8. - let phone cool down with full battery
9. - Dial *#*#4636#*#* turn off radio?
10. - cry

I remember back when I had an HTC evo 4G everything was so simple...
I installed ROMs like crazy with no errors.

can anyone help me get my cellular service working?

Building trltespr Note4 kernel 5.1.1 Errors (mismatch)

Attempting to build this a few times. Keep running into these 2 mismatches. I am using the arm-eabi-4.8 toolchain downloaded from google. The source is clean released by google. Only change i made was disable samsung's root protection feature.

i do

make -C $(pwd) O=$(pwd)/out VARIANT_DEFCONFIG=apq8084_sec_trlte_spr_defconfig apq8084_sec_defconfig SELINUX_DEFCONFIG=selinux_defconfig SELINUX_LOG_DEFCONFIG=selinux_log_defconfig TIMA_DEFCONFIG=tima_defconfig DMVERITY_DEFCONFIG=dmverity_defconfig

make menuconfig
(change this feature in kernel hacking)

make -C $(pwd) O=$(pwd)/out

My gcc and jdk

Linux version 3.19.0-25-generic (buildd@lgw01-20) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 (Ubuntu 3.19.0-25.26~14.04.1-generic 3.19.8-ckt2)

OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)

I then receive these errors

Is the Note4 really 802.11ac WiFi compatible?

I recently upgraded to a new 802.11ac router.
All my other ac equipped devices work well in the full dual-band mode. But not the Note4. It doesn't want to use the two bands together, with the full added bandwidth.
The Note4 is supposed to be ac compatible, but mine will only use one band or the other. In normal use it only locks onto the 2.4GHz channel.
If I switch off the router's 2.4GHz channel, the Note4 locks onto the 5GHz channel straight away, no problem. And of course it has more bandwidth.
But as soon as I turn the 2.4GHz signal back on again, the Note4 goes back to the 2.4GHz channel only.

This happens regardless of the phone being close to the router with big signals on both bands, or further away with weaker signals.

I've tried using the 'Smart Network Switch on and off, but that seems to make no difference.

Any ideas?

Edited to say: The channels I'm using are both clear of interference, checked with inSSIDer.
