I have installed 19.07-snapshot on wrt1200ac linksys.
and I selected to keep old setting.
now I have a weird problem.
lan clients dont seem to be able to see each other.
they all see router and wan and internet works, but I cant even ping from my laptop to my tablet.
other programs that use lan to communicate with others (like syncthing) don't work.
what I am missing?
I have checked and wifi client isolation is not enabled.
It is not advisable to keep settings between versions. Have you tested configuring from default configs?
the router is not in a realy accessable place and I lack the proper lan wire.
so I need the wireless and I really prefer not to start from scratch.
other stuff works and only bugs I have are those that were present in 18 too, except this one
There is an option on the wireless interface precisely to isolate clients from each other. Check that it hasn't been activated accidentally.
see first post
Sorry, I did not see that line the first time...
There have been reports of similar behaviour before, and this usually indicates a bug in the wireless drivers. However, I am not aware of any recent development on those devices.
Not being very helpful, I know...
I had this enabled which seemed to work with snapshot(not 19-snapshot but the git snapshot) image and but seems to cause this issue with the 19 image.
"802.11w Management Frame Protection"
I disabled it (it was on optional) and now lan clients see each other.
