Thanks, maurer! But what about the flash/RAM? WR702N seems to have AR9331 as well, but it only has 2MB flash and 16MB RAM which are not capable to run OpenWrt.
So I'm curious whether MR11U is based on WR702N or WR703N.
check the pictures http://bbs.mydigit.cn/read.php?tid=334500 - it need registration
i was lazy to make an account on that site

Hello, the chips are:
RAM is:
Zentel
A3S56D40FTP - G5
CPU/NIC is:
ATHEROS
AR9331-AL1A
PBT198.006C
1133
KOREA
flash is:
SPANSION
FL032PIF
Is this information enough to decide the capacity of flash/RAM? I mean I don't quite know the datasheet of Zentel and Spansion. Thanks~
refferance: http://www.dd-wrt.com/wiki/index.php/TP-LINK_TL-WR841ND
Spansion FL032PIF 32Mbit (4Mb) Flash
Zentel A3S56D40FTP -G5 (32Mb) Ram
Does this have serial pads?
Also this is the pic (pls mirror it before they block it..)

but the RAM is covered with a sticker, how can it be known to be Zentel A3S56D40FTP - G5
Also where is the flash? I can't see it in the pic (SPANSION FL032PIF)

Battery (how to buy this?) http://img.mydigit.net/Mon_1111/88_8972 … 4d4436.jpg
pls mirror the pics asap
pls make wiki entry for this modem
has anyone brought it in North America?

good news, mr11u is openwrt compatible. i've just flashed OP on it by modifying the firmware header. it works just perfectly as 703N except for that Wireless LED and another LED indicators are not working. for purchase,http://www.volumerates.com/product/tp-link-tl-mr11u-pocketable-11n-150m-3g-mobile-wireless-broadband-router-with-built-in-lithium-battery--white-101760

Sure it has serail pads, its the four holes you see in one of the pictures under the TP-LINK text. It also has the same type of memory as my 703N, which I'll hardmod to 64MB. I have a sourced so-dimm here with Hynix HY5DU121622CTP-D43 chips on it, so I might as well mod both. Ordered.

Thanks, VRS. Really good news. However, AFAIK, TP-LINK hasn't released the official firmware for it. How can I backup the original firmware on it in case the flashed openwrt doesn't work?
BTW, did you modify the header of firmware of WR703N? Could you plz tell me how to do that? It's better if you could tell me what bytes to change rather than prewritten tools. Thanks!
Does this have problem powering some USB dongles like the 703?
ok, here is how it went. I uploaded VRS mr11u.bin firmware. The unit appeared unresponsive after flash. I tried the static IP assignment i.e assume that 192.168.1.1 for MRU11/openwrt and 192.168.1.2 for my laptop. Restart the device. Initiated ping from laptop to MRU11. after few seconds restart period, the unit responded to the ping request for about 25 seconds. After this period there was no response. I used wireshark (network analyzer) to see what is going on. Upon restart I saw that the MRU11 unit sends PPPOED PADI packets. I was trying to see if I could reflash it using tftp, but here I see the unit trying to do the PPPOE thingy. Did some research found that the tftp may not work till we have good wan. So far so good. Next I tried the reset button to see if I could boot into safe mode. Tried that and I was able to telnet into the device. Looked at /etc/config/network. the wan and wan1 interfaces are set for pppoe with user/pass test/test. Mounted jffs using mount_root. Seems like not enough space for jffs. I get the following messages from mount_root.
/sbin/mount_root: line 1: pi_include: not found
/sbin/mount_root: line 1: pi_include: not found
/sbin/mount_root: line 1: set_jffs_mp: not found
/sbin/mount_root: line 1: determine_root_device: not found
/sbin/mount_root: line 1: can't create /.extroot.md5sum: Read-only file system
switching to jffs2
if I try df after mount_root, this is what I get.
root@(none):/rom/etc# df
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 448 220 228 49% /

/dev/mtdblock3 448 220 228 49% /overlay
overlayfs:/overlay 448 220 228 49% /
I check against my 703n for comparison, this is what 703n shows.
root@(none):/# df

I suppose the image file is too big or some thing ? So it boils down to I need to compile my own image. I have the toolchains installed. I will try to download the source files. I will use 703n as my base. The question is what do I need to change ? I suppose some signature or hardware id ? if any one can guide me, I will appreciate it.
