Hi,

Is that a ZTE modem?

I'd be pretty certain that your LTE modem is not supported as it almost certainly requires special modem drivers (QMI most probably).

TPLINK is completely at sea with LTE drivers and the special imbedded protocol requirements that makes these modems communicate at top speed.

The only LTE modems that currently work ( MF821, Sierra 320U etc) are those that have dual protocols embedded and work the old slow PPP protocol in addition to the faster ones.

I've got no where in my communications.

Good luck.

I OWN A MR 3220 V2
IF YOU OWN A VODAFONE K5006Z (WHICH IT IS NOT SUPPORTED FROM TP-LINK). DOWNLOAD AND UPGRADE WITH OPENWRT FIRMWARE FROM THIS LINK http://ofmodemsandmen.com/download/Huntsman/openwrt-mr3220-v2-HM2013-10-12.bin
ENTER MANUAL APN, USER AND PASSWORD IF REQUIRED AND CONNECTS IN 90 SECONDS FROM START. IT WORKED FOR ME LIKE PLUG AND PLAY.
for 3420 v2 this should be fine but not tested by me. http://ofmodemsandmen.com/download/Huntsman/openwrt-mr3420-v2-HM2013-10-12.bin
