[LEDE-DEV] wds link problem

[J Mo]

Hi

I am mentioned in that ticket you linked. I've seen similar problems, 
but I'm not positive that my situation wasn't just a hardware failure. I 
will get in contact with that tribut person and work with him. Thanks 
for bringing this to my attention.

Anyway, your problem is different. TP-Link uses proprietary 
closed-source drivers. It's probably not even using hostapd or iw. It 
probably requires something proprietary to make it work. It would not 
surprise me if they had purposefully disabled non-TP-Link bridge clients.

This sounds like a TP-Link problem. There is likely nothing you can do 
about it (except to use LEDE/OpenWRT instead).

Most different closed-source wireless implementations won't bridge with 
each other. I don't even think 4-address bridging is a de-facto standard 
yet, though it's getting there.

I think you are out of luck and will not be able to fix this.

As a tangential gripe, I don't like the term "WDS". I suggest "wireless 
bridging" or "802.11 bridging" instead. "WDS" as a term should be 
depreciated. WDS doesn't mean wireless bridging and wireless bridging 
doesn't mean WDS. Reference:
