Hi all,
I'm struggling on getting my 802.11s stable for more than 2 days. I first notice this when I tried FW build from 11/29/2024. I have 3 Linksys MX4300 in the mesh. Less than a dozen devices at my place. I followed https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=337443&highlight=802+11s+mesh to setup wifi routers. I tried to form mesh on wlan0(5G-1) and wlan2(5G-2). I observed same issue. I also tried to enable Gate Announcements and HWMP Rootmode. They don't help. I usually observe one of the follower nodes drops from the mesh and need to reboot the node to recover it. When this happened, I can always connect to my follower node with ethernet cable with manually configured IP and check the web ui. I could not tell why it has difficulty to connect to the primary node. I even tried to turn on and off the wireless interface and it did not help.
The primary node that attaches to the modem is always good. I never need to reboot that one.
Any suggestions what I can do to help on this? What information I can provide to help debugging this?
I only experienced this issue whenever I added a Netgear R7800 as a second secondary node. I assumed it was just instability with 802.11s on the r7800, since it took quite a few reboots just to get the radio turned on in 802.11s mode.
You might try enabling "Avoid Multi-Hop Path Discovery" and see if that makes any difference. I recently turned on "Announce Connected to Gate" and "Announce Connected to Auth-Server" but cannot see this being logged anywhere. In fact, I can not see anything from the mesh being logged for that matter. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429

Thank you, @lexridge.
I do agree with you on logs about mesh. I could not see anything useful in the log, which may help to identify the problem.
Actually, I kind of recall this problem when I add 3rd node and upgrade to 11/29 firmware. I will try this. setting and report back here.
For some reason, DD-WRT does not take enable on Avoid Multi-Hop Path Discovery. Whenever I clicked on save or reply, it resets back to disable. Maybe I'm missing something here?
Maybe try manually setting it? Following the conventions of all the other mesh nvram variables associated with the mesh, this may be a way to manually set it:
Code:
nvram set wlan0_mesh_avoid_multi_hop_path_discovery=1 ; nvram commit ; reboot
Be sure to take a backup before trying this, just in case.
EDIT: Just tried this myself. It does not turn on the option in the WebUI once set manually and rebooted so this probably is not correct. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429
