[Q] No 3g signal, dropping wifi connections...

Hi guys, I got my Samsung Omnia 7 yesterday, been having fun with it at home however it keeps disconnecting/reconnecting to my wifi, which is odd in itself, even if I stand right next to the router.
More annoying than this however, is that I was out and about today, in the center of a city where I know has full Orange 3g signal (my friend on Orange was with me) and I had no 3g. Absolute pain as I wanted to show off my new phone, but it couldn't do anything!
I then went about 10 miles away to another area with full Orange 3g signal and have nothing! I have no 3g in my house, at college, in town, it's ridiculous. A soft reset will sometimes make it work for all of 30 seconds before it drops again!
Anyone else having these issues? Hardware or software related? Cheers guys, Jacob.
Hmm my 3g has all of a sudden come on with full bars :S Maybe it was a network issue after all...

What control's the cell phone signal?

I am using an unlocked ATT Note 2 on T-Mobile. I have great 4G! Coverage and Wifi works but the cellular signal hangs at one bar to 0 bars often going into emergency call only mode. After a while the signal will go back up to on or two bars and I get service again. What control's the cell phone signal (is it just an antenna or is it software based). I have flashed the original modem, the second upgraded modem and now I am on M6. The signal continues to do the excat same thing through each flash. I have tried different ROMS and the same thing occurs. I did not slight decrease in the jumps to "emergency call only" mode after upgrading to MK6. Are the an other things that I could try or should I have the internal antenna looked at?
The modem controls the cell signal!! The antenna is in the top right corner. Ya know some cases cuz signal problems!!
Could be a number of things causing the problem...[emoji43]
And you are on the same modem I'm using fyi... MK6
It's not Rom related that's for SURE!!!
Notice you stated another thread kinda pertaining to the same THING!![emoji102][emoji782]
