Found a new device today.

MR11U, basically it's a MR3020 come with battery. I might get one
Small size, come with battery, USB port. Can be modded into downloading rig

http://wiki.openwrt.org/toh/tp-link/tl-mr11u

so far for TP LINK 3G router, i have confident in MR3420 this model only,

the rest like MR3220, MR3020, MR3040 all have quite a lot of issu from many user feed back, hmm.gif

TL-MR-3220 work flawlessly with my new Sierra AirCard 320U LTE modem, at first I was thinking need to find the additional modem bin file as this 320U modem did not listed inside tplink 3g modem work list. End up, just plug N play. biggrin.gif  rclxms.gif

the 3G signals part (from MR-3220 console), 320U keep showing 35% , while E1762 jumping btw 19% - 25%.

Now only a question left, unsure if MR-3220 will optimize the Sierra AirCard "Tru-Flow" feature compare to direct USB modem onto laptop.

same problem b4, nothing to do with firmware.

Brought MR3220 & E1762 to office (different location) and test it, speed back to normal. End up connectify for the solution  biggrin.gif

good to know your seirra woorking well with your MR3220 notworthy.gif

My MR3420 cannot survive with TP-link official firmware.
Official firmware throttle my speed to 0.1~0.01mbps speed
So I did some research and found the tutorial to flash openwrt on this website. I find it very Newbie Friendly, so I decided to share the link here.
http://www.kaskus.co.id/showthread.php?t=10124215

Don't forget to remove the %2A when download the openwrt firmware
http://www.4%2Ashared.com/file/LqtTaVCL/openwrt-mr3420-v1-squashfs-fac.html

Flashing openwrt require patient and time, configure can be tough for newbie. I manage to install miniupnp and setup DNS myself by googling for 1 days. I brick once my MR3420 once for wrong DNS configuration, but I manage to save back my router due to the very powerful failover function.

Openwrt is damn fast and powerful, allow 3G modem to successfully dial connection within 10sec. Damn love openwrt now, my speed damn so consistent all the time 10mbps++

Now I facing a problem is that my 3G modem will dc after idle sometime (few hour), it always dc when there is very less Active IP Connections. (DC when I didn't open any download) I always face dc problem when I put the connection to be on and idle overnight. Although I have set my auto-disconnect value to 0 or a very large value, the DC problem still occur when there is very less Active IP Connections and it idle for long time.  The auto-reconnect function in Openwrt is not working as what I expected

I saw something like this in my log, I notice there is auto-reconnect mechanism running but it is not successful. I click restart connection button on openwrt network interface webconfig page but it still fail to connect. I found that I have to manually restart the network interface (WAN) so that it only can successfuly reconnect. I use  ifdown wan0 ifup wan0 in SSH to let it restart the network interface.  Anyone have idea/script how to solve this?

ok.. my 3420 is acting up.. when my e372 is direct to pc, i can get 300kB-400kB dl.. when at router.. its almost down to its knee...

n my e372 is heating up.. requiring reconnect every 5min or so.. hai..
*
then i guess you need cooling fan to cool down your router + E372,.. heat up modem E372 even with open wrt also useless notworthy.gif

Thats weird, mayb the one you use is old version of Openwrt?
The one I am using can support E372 and MF680, I just get it from Kaskus forum  tongue.gif
Beside the reconnect issue, openwrt is Very fast, stable and powerful.
Can install extra module like transmission torrent dl  laugh.gif

can give me the link where to download the firmware u are using ? icon_question.gif


Added on October 18, 2012, 5:40 amspeed this hour on tp link stock firmware is good,

the Open WRT firmware can't Reconnect after DC doh.gif

But 753s its not lte modem but still have 2 port for external antenna. Mf680 should make 2 port.....

that's why external antenna is strong not suggested for DC-HSPA+ modem with single external antenna hole,.

chuahcs79,
I think the problem that your MF680 and E372 is not detected is due to this 2 module
usb-modeswitch and usb-modeswitch-data
I having the same problem becos I follow blindly on kizwan guide.  rclxub.gif
kizwan guide is very good already, I think he just forgot to mention on usb-modeswitch and usb-modeswitch-data

Remember to reboot router after install all the module
I manage to connected to 3G using ttyUSB1
*
wow after load the usb-modeswitch & usb-modeswitch-data my ZTE MF680 connect in 1 second after reboot shocking.gif

it was done now, whewww,.

big thanks to -> Kizwan

also thanks to ruzumaki too notworthy.gif
