Help S4 Random loss of Signal after Root topic

HI

Ever since I Rooted my S4 and installed Carbon rom I having real random loss of network signal.

Some times hours can go by and its fine to 30 mins passing by and loss.

Can guarantee while moving in the car it will happen as you pass between cell mass.

Never happened before I rooted so can only image I have done some thing wrong, I used to have a HTC one and they was so simple to root and to stick a rom on.

The Samsung phone have more steps to them that I can only image I messed up some were along the line , any one with good knowledge care to take a look a my Samsung info screen shots and see if iv done some thing stupid.

Tried forcing 3g only or GSM make no difference tried two other roms and the same happens

LTE loss with KitKat topic

I seem to have a small dilemma with my Galaxy S4 and was wondering if anyone could help. I just upgraded to Fenny's 4.4 and I'm noticing my LTE speeds are really slow compared to when I was 4.2 (Came from 4.2 to 4.4). Basically I have very little to no LTE speeds, though I have LTE under my data connection.

Details
---------------------------------

Rom: Fenny's Stock 4.4 Rooted (1.1) http://forum.xda-developers.com/show....php?t=2679913
Baseband: NB4 http://forum.xda-developers.com/show....php?t=2678774
Bootloader: MDL
Recovery: CWM Touch

Did I miss to flash anything else? I already flashed the NB4 modem. Going back to MDL modem does nothing to help.

Thanks!

[Q] Loss of WIFI using backup stock ROM topic

I have installed safestrap on my Kindle Fire HDX 7 and backed up the stock ROM to Rom slot 1. However, when I am using the backed up Stock ROM I can get no WIFI connection. There is nothing wrong with the router which is only a few feet away from the Kindle. Any help/advice would be appreciated. Thanks
