I see the same thing, assuming that a VAP is just having an access point configured on the same radio. I see it even when I configure a single AP on the radio and enable it, my phone instantly says that Download is like 200MBit, vs. the 1 point something K I see when I disable it. Hardware is Netgear WAX206 (23.05-SNAPSHOT r23353-9d10944de7 on mediatek/mt7622) and a Mercusys MR90X (23.05-SNAPSHOT r23353-9d10944de7 on mediatek/filogic (mercusys,mr90x-v1)). |

Glad to see it's reproducible by others. The 3x VAPs vs 1x may be an artifact of MT7622 vs MT7986, but not sure. |
|
Looks like latest snapshot seems to have fixed this bug. I need to check the hostapd version now to work around the unable to connect/wrong key issue. |
|
Just to be clear, that is a different version than I am running currently, so no 23.05 snapshot? Because this morning I saw that I got full bandwidth at my main router but the reduced when connected to the WiFi of the meshed Netgear, I didn't have time to investigate though why. I power cycle them every night, so I was wondering if this has something to do with it and there is a timing issue in there. Mesh was working perfectly as usual. So this is what I see on the MR90X (standing in front, so no interference) And this is what I see on the WAX206 |
|
The fix seems to be in latest OpenWrt "rolling" snapshot, not the 23.05 snapshot. I havent checked 23.05 snapshots yet. |
|
Do you have any indication as to which change fixed that? |
|
I don't as of yet. Prior, I was running a 23.05 snapshot from a month or so ago. I took a brief look through the MT76 commit but didn't see anything relevant. Perhaps it was a hostapd issue? There were a good amount of patches recently. |
|
23.05 snapshots are still "broken". Building from main branch seems to work normally. |
|
It is fixed in the 23.05 Snapshots for me, I guess due to 9720b09 Should be in 23.05-rc4 then. |
Describe the bug
Since ~May, MT76 has had an issue where a single radio running (1) 802.11s node and (3) or more VAPS causes any STA's max receive bandwidth to be limited to 20MHz.
Remove the 802.11s node OR have 2 or less VAPs and 40 and 80MHz works fine.
I do think this is related to the problems addressed in:
openwrt/mt76@c50be0b
openwrt/mt76@d7d7479
openwrt/mt76@1377f58
openwrt/mt76@f704e4f
... as the problem arose exactly at the same time.
For context, this is using wpad-mesh-openssl. The bandwidth across the actual 802.11s link is fine, working at 80MHz as expected. Ping @nbd168 for visibility. Not sure if this is specific to MT76 as I'm unable to test another device, but it happened at the same time as all the other regressions.

Steps to reproduce
Actual behaviour
STAs on a radio hosting (1) 802.11s node and 3 or more VAPs are limited to 20MHz bandwidth. The mesh node bandwidth is fine.
Expected behaviour
Bandwidth on a VAP when on a radio with (1) 802.11s node and 3 or more VAPS is not limited to 20MHz.
