if you have rooter, try to plug in and see

yes you can,

check under network status, make sure you are connected to same cell tower like your direct plugin, and also if 3G best under DC-HSPA+, or yet best is 4G for lower ping with good modem

manual add schedule task only apply to openwrt Altitude adjustment/backfire only

for rooter wise, u dont need to do that, just go to modem tab -> under connection -> keep connection alive option -> enable or enable with reboot.. -> save and apply,.

if you done that, then nothing wrong config with your router,
you should check with your modem seller ,..

only thing u can do is flash it back to original stock firmware then reflash it again to rooter,

flash with lan cable connection only,

did u try the original stock firmware ? can it dialing for you ?

have u try this newest firmware that support E3276 TL-MR3420_V2_130314_FI from here ?

i also same error when trying to install any other packages too,

but it was fine when i install it in openwrt Altitude adjustment 12.09 RC1 though

blacktubi gastacopz

actually All rooter can dial,

u dont have to convert the modem into regular modem at all,.

just follow steps below:

-reboot your router
-plugin your E3276 modem
- login LuCI web interface
- sign in
- go to modem Tab
- go to Custom
- paste the AT command ( provide by blacktubi : AT^SETPORT="A1,A2;10,12,16,13,A1,A2")
- click submit
- wait for the submit done

* Key : you must paste the AT command FAST whenever you ON/REBOOT the router , otherwise the rooter wont able to recognize which port is which port,.


or you also can try TpLINK MR-3420 V2 latest beta firmware which support E3276
-> Latest Beta Stock firmware 130314-FI

Enjoy

you can ask him to try this first,.. a few user E3276 works with this method,
just though sharing only,.

after paste the AT command,

it will looks like this :

u can try these few solution :

1) try to update your firmware to latest

2) try to add E398 bin file into modem setting

if still cannot works, then is bug, original stock firmware have this signal bug,

so just flash to Rooter openwrt firmware -> http://www.ofmodemsandmen.com/downloads.html

below are step on how to flash from original stock firmware to Rooter openwrt


go to -> http://www.ofmodemsandmen.com/downloads.html

looks for TP-Link MR3420 V2

download this : Huntsman 2013-10-16 Latest Release

then go to your web interface 192.168.0.1

sign in

make sure you use Lan cable connection and not wifi

go to the last tab system -> firmware

click choose -> find the Huntsman 2013-10-16 Latest Release for V2 u download just now,

click ok to proceed,

then wait,. do not turn off router or make sure no power cut off,..

wait until the router fully done,

clear your browser cache

then login 192.168.1.1

direct click login for first time

then go to system -> administration -> setup your LuCI web interface password -> select Lan at below option -> click save and apply

go to modem -> connection -> set up your APN -> and click enable in keep connection alive -> click save and apply in bottom

now go to network -> wifi -> click edit -> set up your wifi SSID, Channel, channel Width, and your wifi password encryption -> click save and apply


after all above done, -> go to system -> reboot -> perform reboot


all is done and it will be auto recognize and dial and reconnect too,.

Enjoy

if after u did all that still 0% signal, then it is a bug,. stock firmware buggy sometimes due to the support is not really up to date with newer 4G LTE modem

did you try to paste the AT command method in rooter ?

so far my E3276 dailing is good and stable in Rooter though



most important is the RSCP & ECIO,..

i am using TL-MR3420 V2 with huntsman rooter 16-10 red

after you reflashed , it suppose to be brand new start,.. did u apply the AT command ?
