Goal: setup C-Bridge over 5GHz band. C-Bridge 2.4GHz radio ('Wireless Network Mode') disabled
rXXXXu@ECHO:/tmp/home/root# uname -a
Linux ECHO 2.6.36.4brcmarm #1 SMP PREEMPT Sat Sep 20 15:01:26 EDT 2014 armv7l GNU/Linux
Attempts to setup a client bridge have failed: unable to ping the gateway from the command line of the C-Bridge. This condensed procedure is based on the C-Bridge Wiki:
Quote:
LAN SETUP: Setup -> Basic Setup
1) Assign Gateway IP: 192.168.8.1
2) Assign LAN IP: 192.168.8.3
3) Turn-off DHCP Server
4) Configure Network static IP with new gateway IP
RADIO SETUP: Wireless -> Basic
* Wireless Mode = 'client bridge'
* Network Mode = match primary router
* Wireless Channel = match primary router
* Channel Width = match primary router
* Wireless Network Name = match primary router
Questions
=========
1) Based on the uname response, is this posted in the right forum (Broadcom and not ARM)?
2) Given that I am using two identical routers, but with different firmware, is there any reason why a client bridge should not work?

Any actionable suggestions or diagnostic questions are highly appreciated. Thank you.
Unfortunately, radio bridging is broken on many routers when using DD-WRT firmwares after build 27343. Your CB configuration settings appear to be correct.
If possible, a screenshot of the CB's Status -> Wireless webpage would be helpful to confirm that the 5GHz transmitter is shutdown while on 27413. (This assumes that you set a static IP address in your PC on the same subnet as the CB and is ethernet connected to the CB.)
A quick but temporary solution may be to execute rc restart on the CB's Administration -> Commands webpage. (Even if this solves your problem, do not put this comand in a startup script as it will cause a restart loop. A more permanent solution may be to flash 27343 to your CB for now.
I'm currently testing a startup script to fix Repeater Bridges (and Client Bridges?) for the R7000, WZR-D1800H, and WZR-1750DHP routers and should be applicable to others as well.
Update1:
Using the wiki as a guide I had no problem configuring an WZR-1750DHP using build 27734 to run as a Client Bridge to an R7000 Prime router using build 25974. Repeater Bridge is still problematic. My comments above really apply only to RB.

@Magnetron1.1: Thank you for the suggestion: although the original subject was the C-bridge it is the repeater bridge top be the ultimate goal. the R-bridge has the incremental advantage of allowing wireless clients.
I am curious as to how one would come across the information as to which build to use?
Key Steps
1) Assign LAN IP and gateway
2) Disable SPI Firewall
3) Setup -> Advance Routing -> operating mode = router
4) Set WPA2 AES encryption to match primary router
5) Status -> Wireless -> Site Survey -> Join
