Posted: Mon Aug 31, 2020 18:24 Post subject: R8000 - r44251 - Cannot bridge wireless interfaces (solved)
TL;DR - Update September 1, 2020
The "issue" reported here was not actually a bug, but my failure to understand how to assign WiFi & eEthernet interfaces to a new bridge. See EGC's replies for the answer.
Router Model / Version: Netgear r8000
Previous Firmware: Tomato firmware (new to DD-WRT)
Current Firmware: DD-WRT v3.0-r44251 std (08/27/20)
Kernel: Linux 4.4.233 #936 SMP Thu Aug 27 17:44:00 +04 2020 armv7l
Reset: Yes. Once before, once after
Mode: Wireless - AP
Issues: In Setup > Networking > Assign to Bridge, wireless interfaces are missing from the "Interfaces" column. The result is that you cannot assign a wireless interface to a bridge you create. I am attaching an image to illustrate this problem.
Can anyone else reproduce? If so, I will file bug report.
I also ran into this issue in a June build I tried.
1. Followed upgrade procedure. Attempted 30/30/30.
2. Downgraded to another recent build (June--don't remember which. Problem was present here as well)
3. Reset to factory defaults. No change.
1. Originally running tomato. Reset to defaults, performed 30/30/30. Flashed to DD-WRT using nmrpflash (factory-to-DDWRT image). Performed 30/30/30. Installed same version using Web upgrade file. Performed 30/30/30.
Personal experience and aptitude
* Worked as network engineer and sysadmin for several years. Familiar with advanced routing and switching concepts.
* Serviceable Linux administration knowledge.
* New to DD-WRT.

Thank you for replying. Yes, I am keeping all of the interfaces at default as opposed to selecting "unbridged".
I am posting a diagram of my simplified network topology to show you what I am trying to accomplish.
I have a Netgear R8000 that has an uplink to a router, that is in turn connected to the outside world.
Basically, my Netgear R8000 has 3 wifi radios that I want to bridge 3 different VLANs (note, one radio will broadcast two different SSIDs, like a guest network).
I am assigning them to different bridges for security & bandwidth reasons. For example, I will have one bridge for untrusted IoT devices, and that will be associated with a certain VLAN. Security is the primary reason I am doing this.
I am also trying to prevent any potential traffic bottlenecks. The WiFi bandwidth of this AP is 3.2Gbps theoretical (5ghz 1.3Gbps, 5ghz #2 1.3Gbps, 2.4Ghz 600Mbps). Assuming real-world speed is half and all radios are saturated, that's too much data than can be transferred over the R8000's 1Gbps ethernet port. My solution is to dedicate one ethernet port to each bridge to make sure WiFi data never gets bottlenecked on the 1Gbps uplink to my router.
