Hi alfa33!
Do you have this release of firmware (I mean r31650)? How can I get it for my 3020 ver. 1.6?

(Last edited by AlexSpb on 31 May 2012, 08:40)

But I have some problem with r31650 version of firmware. I can`t install some packages for 3G modems. How can I install it on a old kernel (3.3.5-1, new firmware has 3.3.7-1 version)

I compiled new firmware - r32012. MR3020 working fine with it. Lan is OK! If you need this firmware - let me know by e-mail or ICQ.

Have u tried USB Storage with it? - It failed several times for me in past. Already mentioned in this thread. Havn't found any Solution yet, but also had less time to investigate further.

USB storage, no problem at all.

Hello, I have a problem with MR-3020 and Openwrt, I succesfuly uploaded OpenWRT on MR-3020 but after reboot I can't connect to it, telnet doesn't work, SSH doesn't work and fail safe mode not to, maybe I miss something, if someoen has any solution

try failsafe mode,
connect lan to PC, change PC IP 192.168.1.10 , subnet 255.255.255.0 , leave gateway and DNS blank
1. turn off
2. turn on
3. press wps button rapidly
4. wps led will blinking around 3 times per/sec ( router entering failsafe mode)
5. now you can ssh or telnet to you router

good luck

ver 1.7 supported?

I bricked my ver 1.4... replaced with ver 1.7.

for bricked 1.4 box, looks like it nv boot up, as the LED will light up sequentially, round and round, nv stop. anything I can try to fix it?

Looking forward to your expertise.

Got a few Ver1.7 here, so far no go but trying latest trunk today and see if r32012 works. Will post later.

I've read a lot about openWrt but still no idea how to flash via serial port.

Do you have any suggestion on detailed wiki on this part? and I am quite curious if I can bring my ver 1.4 back to normal.

Thanks.

linky http://wiki.openwrt.org/toh/tp-link/tl- … tp.experts

MR3020 1.6 S/N:11C6590xxxx with r31650 no ethernet.

r32012 re-flashed via tftp works fine !

r32012 tested on Ver1.7 hardware, no Ethernet still, but works fine on Ver1.6.

building r32020 and will try that.

tried r32020 still no Ethernet link

I Ordert an MR-3020 do i understand it right that bin flash over the stock firmware web interface works with the latest trunk version of OpenWRT with v1.0 v1.4 and v1.6 but no ethernet with v1.7?

thanks for help

and how to know the build ver no.? like r31650 r32020...

It doesn't work, the MR-3020's IP is 192.168.1.1 isn't it?

To enter Failsafe mode is very easy, no need to press the button "rapidly" or hold the key etc....

During powerup, when the light Start Flashing (Power or WPS light), "single click" on the button within the first 5s
Means that just press the button (reset or wps whatever),
the light would be flashing triple faster, now it is in Failsafe mode.

Very easy, no need to keep pressing, no need to hold the key during powerup......
Every models with openwrt just like that.

Hello, I have a problem with MR-3020 and Openwrt, I succesfuly uploaded OpenWRT on MR-3020 but after update firmware after reboot it does't work. All LEDs blinks around once in 5 sec. I can't connect to it, telnet doesn't work, SSH doesn't work and fail safe mode not to, maybe I miss something, if someoen has any solution.

Just to confirm that MR3020 Hardware Rev 1.7 is now working using build r32093 onwards, tested on r32109, (Ethernet comes up fine). Many many thanks to the devs for sorting this. Good job!

Hey Everyone!

Having a problem where my TL-MR3020 is only working with 1 usb device (the very first one I ever plugged in:

root@OpenWrt:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 041e:4034 Creative Technology, Ltd Webcam Instant

Any other devices plugged in do not light up the usb LED on the unit, and put errors in dmesg such as:

hub 1-0:1.0: unable to enumerate USB device on port 1
or
hub 1-0:1.0: connect-debounce failed, port 1 disabled

I have reflashed the unit with stock TP-link firmware, restored to factory defaults, reinstalled openwrt, and issue persists.

Anyone have any suggestions for me? Thanks to everyone in the openwrt community!

Hi all,

I've successfully installed OpenWRT (r31835) to my 3020. Ethernet works fine, however when I enable WIFI in/etc/config/wireless the device does not come up after reboot, WSP led blinking, and rebooting every minuit or so.
I can then move to failsave and reset/disable the wifi config, but I'de rather get WIFI up and running

Below the config I currently have (default as it came with the image) and a dmesg dump
Am I missing something here? Any pointers are much appreciated.

Hey guys!
I have a problem with my 3020.
I worte a C program that prints the bytes it receives on ttyUSB0. The serial settings like baudrae and such are set within the program.
The thing is, before running the program I still have to use stty to set the serial settings. If I dont, my program does not print a thing.
Anyone has a clue?
