my problem modem + router 3420 , will no conection awhile
direct plug pc no this problem very smooth conection
no connection a while as in? disconnect after say 5 minutes usage? or will need to wait a while everytime when you load a page, say maybe u load google.com, fail, but when u try again in a minute it's ok again?
what is your network setting on router for the 3G/4G setting, maybe a screen shot might help us help u

wait, i think you mentioned MR4320, v1 and v2 also a bit problem.. are you using E398 also? some USB modem are eating more power then being supplied, so maybe u can get a USB y-cable ( 2 usb male - one usb female ) and plug one to your modem, another one to another power source, and try again if it works, but you need to test if the modem is detectable with an extension or not, technically speaking shouldn't be a problem
