hi guys, i just bought e3276s-151 with firmware version of 21.260.05.00.00 and pair with tp-link tlmr 3420 firmware v2.4 .

somehow i installed three version of firmware from http://www.ofmodemsandmen.com/downloads.html yet still i failed to connect to internet when the usb dongle modem is plugged into the router.

can all sifu please give me some helps on this ?

i even flashed to the Huntsman 2013-10-12 / LuCI Trunk (svn-r9811) yet still failed to connect .

my usb dongle modem works fine as it can connect to internet when directly plug into my laptop.

on the other hand, can i know how to flash back to stock tp-link stock firmware? i try to flash back from openwrt firmware but failed. and i got this notification - The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.

I download the tp-link firmware from here.

i wonder the connection type shown on the usb dongle there - RAR(modem) and NDIS. which one should i use ? or either way works fine ?
