This is the response I was given when I inquired yesterday:

these issues are very old and i have multiple of such routers running
That being said: Has anyone provided troubleshooting debug information via syslog, dmesg, serial console output? I provided the only information I could find that might be suspect in the public svn repository in the previously mentioned ticket. This is the last comment from the ticket, ~8 hours ago:

the forwarding issue is fixed since many months.
Flash today's build(06-19-2020-r43471), test, report in the build thread and provide concise proof both in the build thread and on the ticket.
If nobody is participating in testing and reporting on these devices, then the issue is not an issue that will get any attention. I am pretty sure that the 4MB flash devices in this family of TP-Link routers don't support 802.11q VLAN tagging, but if they do, then whatever magic voodoo is required to get it to work has not been shared.

Do you have any suggestions on how to provide any meaningful feedback? dmesg is empty probably due to 4MB flash, syslog doesn't mention anything besides daemons running, wireless stuff and NTP. I don't have a serial console output available.

You will have to open the router and install the header for serial console access and get a USB-TTL UART adapter cable to get serial console output. I suspect part of the issue is a K3.x kernel using a K4.x driver, still need to look deeper into the older K3.x code to see if I can make sense of things. Perhaps some of the back-ported patches to the kernel caused issues, who knows. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Well I have investigated on a previous build the switch and I found a weird discrepency between the swconfig output and the nvram data on my WR740N v4. I will check that this is the case in the 43471 build.
The swconfig gives:
Code:
lobal attributes:
enable_vlan: 1
Port 0:
pvid: 1
link: port:0 link:up speed:1000baseT full-duplex txflow rxflow
Port 1:
pvid: 1
link: port:1 link:up speed:100baseT full-duplex auto
Port 2:
pvid: 1
link: port:2 link:up speed:100baseT full-duplex auto
Port 3:
pvid: 1
link: port:3 link:down
Port 4:
pvid: 1
link: port:4 link:down
VLAN 1:
vid: 1
ports: 0 1 2 3 4
nvram show | grep vlan.hwname
size: 18017 bytes (47519 left)
ping_ip=nvram show | grep vlan.hwname
vlan0hwname=et0
vlan1hwname=et0
Which at the least has a numbering issue, in the nvram the two vlans are fine, but looking at port.vlans the numbering is from 1 instead of 0. swconfig shows less ports than those in nvram and I cannot wrap my head around it.

This is what my startup script is on a newly-acquired TL-WR940v3 is, and disabling firewall on win10, I can ping back and forth across the switch without issue.
Code:
sleep 10
swconfig dev switch0 set reset 1
swconfig dev switch0 set enable_vlan 1
swconfig dev eth0 set enable_vlan 1
swconfig dev switch0 set apply
swconfig dev eth0 set apply
As far as multiple vlans, that is another story on how to configure, but for all intents and purposes, this issue is and has been fixed. It was actually working for me just fine with 36330, BEFORE the "fixes", and I am wondering if the "fixes" screwed up 802.1q or not. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"
