Hi wack - I was not able to get to the same point as you. My serial connection does not seem to allow me to send commands to the router. I can however read the messages spilled out by the Router. Can you confirm the pinout you used for tx/rx/vcc/gnd on the board?

BrainSlayer - would you be able to enlighten us with the actual commands we should issue on the router serial console to get the experimental firmware loaded? As wack reported, it seems not to be the same command as for WHR-G300N.
Thanks,

Hi, although it is an old post here is a solution , if you want to actually USE this 9$ WCR-GN router, which is working for me, that I found on Buffalo forum:

Re: How to setup WCR-GN in bridge mode on existing network?
.
Plug your computer into a LAN port on the WCR-GN.

Go to 192.168.11.1 in your web browser.

User name is "root" password is blank (no password) just hit OK after putting in root

You should be in Setup tab. Under Mode Information, click the Bridge Mode circle and click on Apply.

User name is "root" hit OK

click on Wireless Config tab.

click on WDS sub tab

on WDS click on use box, screen will expand.

click on search

click the circle of the row of the ssid of your network, then click select

put in your passkey if any, click apply

unplug your computer from the WCR-GN. Wait 10 seconds, plug back in. You should get a new IP address and be connected to your network.

which it did, and the connection on the WCR-GN is secure too.
If this can help,
Cheers

its now supported. the current experimental builds do contain a image which can be flashed using the serial console


I flashed the firmware successfully using the serial console. Boots up fine and I can configure dd-wrt, but my device can't see the AP in any mode.

Hi,
Unfortunately once you install the Buffalo DD-WRT professional version of firmware, you are not able to downgrade back to the friendly version.


So I'm still stuck on DD-WRT with WiFi not working.
If anyone have solution (original Buffalo fw, or DD-WRT version with WiFi working) it would be nice to share with us.

Thnx.

I can confirm that there is a problem with the wifi on this router with all dd-wrt builds I've tried for wcr-gn. I believe I have a V4. The interesting thing is that it seems to boot up and work and show wireless and all of that if you flash it with the DIR615H build of dd-wrt (chipset is a very close relative), but it keeps restarting shortly after (likely a watchdog timer issue.)

I learnt from other forum. Someone put “site survey” in the “save startup”. This problem was solved. I have not tested it.

I have WCR-GN but I’m not skillful to use TTL. so, I’m using original firmware.

Could you please post the link to that post in the 'other forum'?

Managed to upload the firmware by Serial TTL on WCR-GN but wifi was dead. Did the same with WCR-HP-GN and wifi was working. Reverted back to Buffalo firmware using a file I found in this forum. Want to make one last effort to try WCR-GN with dd-wrt and working wifi. Just need instructions from that post you mentioned.

Thanks.

Hello sannosuke. Could you comment on how did you reverted back to Buffalo firware?

I'm planning to test BrainSlayer's last build for WCR-GN on a couple of this devices that are giving me problems when connected as bridge on the same LAN, but would like to be able to revert to stock firmware in case wifi does not work.

Is there any update on the Buffalo WCR-GN ?

I bought one because it was on the workable router list, and now it seems it isn't.

My status of knowledge is now:

1.) It can not be flashed without opening the case
2.) After a serial flash Wifi will not work


If that's the case I don't think this router belongs in the workable router list.

Any updates on that?

The wifi is working. Only you need to fix the factory setting as per:

At least this solution works for my WCR-GN after hundred trial on other solutions.
