I have two DIR-860L-A1 routers that I would like to connect via a wireless AC-Only bridge. I have tried bridging via both Repeater-Bridge and WDS on various builds (current: v3.0-r40559 and previous) but to no avail.

Outcomes:

Repeater-Bridge
Works (allegedly) for around the first 10 window ping packets immediately after the initial Apply button is clicked. The 11th packet then takes both routers down, with the Repeater-Bridge needing to have a hard reset.

WDS
Routers can establish a WDS Nodes Connection with a valid signal, but no bridging occurs. Note in order to establish a valid signal on the WDS connection, wireless security is required (opposite of the Broadcom WDS walkthrough states); credit goes to a WDS trouble shooting post on the Atheros forum for this tidbit.

Note that I can establish a wl0 N-Only Repeater-Bridge between the routers on almost any given release. All attempts at establishing a wl1 AC-Only bridge have been attempted without any wl0 bridging in place.

Looking for a confirmation that someone has gotten this configuration to work, any needed mystery steps, and maybe even a release number.

thanks

40599 is not the best build see point 8 below

When using a VAP you probably need a workaround like:
4)This one is from @Redhawk (guaranteed to work ):
Code:
sleep 20; stopservice nas; wlconf eth1 down; wlconf eth2 down; wlconf eth1 up; wlconf eth2 up; startservice nas; logger "VAP workaround executed";




Below some pointers which might help to get the best out of DDWRT and out of the forum:
1. Research your router, start with the supported devices wiki:
https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices .
2. In the supported devices wiki you can see if your router is supported and what architecture your router has and if you are lucky also an install guide/wiki.
3. Post in the right forum, from the former step you can see if your router is Broadcom, Qualcomm/Atheros, Marvell or other, use that forum to post router specific questions, for networking questions post in the Advanced Networking forum and for other things in the General Questions forum.
4. When posting always state router model, build number and when applicable the Kernel version.
Describe your problem and how you think it can be solved.
Give as much detail as you can also provide your network setup if applicable.
For your Network setup, state what wiki you have used: https://wiki.dd-wrt.com/wiki/index.php/Linking_Routers
5. When posting pictures make sure the maximum width is not more than 600 pixels.
6. Do not hijack a thread, meaning do not post your own problem in someone else's thread. Just start your own thread. This so that it can be searched and found by others.
7. If your post is answered and your problem solved, mark your thread with [SOLVED] (the header of your first post).
8. Do NOT use the router database, builds can be found at:
https://dd-wrt.com/support/other-downloads/?path=betas%2F2019%2F
All builds are beta including those from the router database.
9. Before uploading a new build to your router, research the build by looking in the build threads.
This is an example of a build thread for build 41686 for Broadcom routers:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=322339
Search build threads with the search function and search on build number.
10. Use the build threads from the former step to report success or problems.
11. For older Broadcom routers (Linksys WRT54 and E series) read the peacock thread although some of it is outdated: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=51486
Builds can be found in the Broadcom directory for Linux kernel 2.4, in Broadcom_K26 for Linux K2.6 and in Broadcom_K3X for Linux K3.X.
12. If you are sure you have discovered a bug, after asking and querying the forum, you can report a real bug in the bug tracker: https://svn.dd-wrt.com/
This is also the place where the commits/changes to the source are administrated.

WDS and bridge modes don't always work on Broadcom ARM. Client-only and Repeater-only may work.

Quote:
3. Bridge modes on k4.4 devices may sometimes work in some configurations in certain builds but are not supported by the bcmdhd driver. Use client or repeater instead as WDS doesn't work with Broadcom ARM either (see Issues below).


Quote:
3. WDS does not work on Broadcom ARM devices (only MIPS<->MIPS)


Those are both posted in build threads in this sub-forum....

Thanks for the help, most the items that were highlighted I had already read, but did not fully understand. Like I did not know that all Broadcom chipsets are ARM based architecture. How much time did I spend performing 30-30-30 resets for no reasons now Crying or Very sad ...

Following these suggestions I went back through the threads and found the following similar routers to the DIR-860L-A1:

    EA6200
    EA6300
    EA6350
    EX6200
    TEW-811DRU


Going through some google kung fu (we need a better search engine already) of the forums, I was able find about a dozen builds that had some confirmation of working for routers above. The most recent build was DD-WRT v3.0-r36410 std 07/28/18

Downgraded both routers to this release, and I was as able to set up the repeater bridge in a few minutes on an AC only channel and low and behold it worked. Very Happy

In hindsight I think this is the first time I ever was able to bridge this router on DD-WRT. My previous routers where N based routers and when upgraded to AC I had no luck.

Looking at the existing 2.4 Ghz repeater that was working, I discovered in was actually running an OpenWrt Padwan variation with a relay add in.

Back to DD-WRT, the performance of this release is excellent on the 5Ghz band, better than when the it was just an access point. The 2.4Ghz was another story. Reviewing the forums over the last month or so I stumbled on to the w0_distance nvram setting. This made a world of difference as ping times on the lan dropped to 1ms and the multiples of 100ms spikes that were occurring secondly went away.

Going for broke I enabled the 2.4GZ band on the repeater router as bridged access point. That performance was pretty terrible thus I have some more work to do. But I am very happy that SIP phone and legacy wireless printer/scanner (WEP only) are connected via the repeater. I still to add another repeater on the 2.4Ghz band to free up the 5Ghz for only video streaming.

Based on the forum, I might be switching the backbone off of broadcom. Current N/AC router inventory:

2 Asus RT-NT-10+ Rev B1 (Ralink RT3050F)
2 DLink 860L Rev A1 (BCM47081A0)
1 DLink 860L Rev B1 (Mediatek MT7621AT)

Seeing if I can find another 860L Rev B1 used off of ebay.

not all broadcom routers are ARM. Broadcom N and before routers were MIPS. ARMs are only the newer Broadcom AC routers, even first AC routers were still MIPS.

look at R6700 from Amazon, was about $62 with a coupon and supported by ddwrt. broadcom ARM.

There are Broadcom MIPS R2 N/AC devices as well. I would have to go through the supported devices list to point them out, but 4606 cpu seems to be one that comes to mind. https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices
