Topic: Wifi Clients isolated, but they should be not...

The content of this topic has been archived on 31 Mar 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi,

can't access nor ping any Wifi client from another wifi client (they are isolated - working connection, properly assigned IP, accessible WAN). I don't recall any configuration change except of compiling from trunk. 1st I tried playing with "option isolate '0'" option, but this didn't help at all.
I don't see any error in logs neither.

Any idea please ? Thank you.

hi

can you ping them from wired lan? or from router? if not check you wifi clients firewalls

@Makarel, thank you, but the only "wired lan" on TPLINK WR850RE is actually WAN and those clients are without firewalls or have them turned off, eg. ChromeCast, Printer ,Linux satbox, Android phones etc.

Sorry @Makarel, I didn't read your whole message.
Yes, I can ping all Wifi devices from router without any problem.
Just between those Wifi clients, no connection/ping is possible. ;-( Not really sure what went wrong here. Even tried to compare older backups from time it was working - didn't find anything which could cause that.
Maybe there is some bug in latest trunk ? Will probably try to revert to some older one to see if there is any change...

So on OpenWrt Chaos Calmer r45851  no problem, ping works, same on r46038, r46160,r46192 - no issues.
Will try the latest trunk if anything got fixed there.

*update* With r46780, r47026 again not working.

Sorry, problem is somewhere in between r46192 and r46780.

So nobody is facing the same problem ?
It should be the same on TP-Link TL-WA850RE, TP-Link TL-WA860RE & TP-Link TL-WA750RE ...and maybe even TP-Link TL-WR700N, TL-WR710N, TL-WR800N, TL-WR841ND v8 & TL-WR1041ND and TP-Link TL-WR841ND ?

Fixed by nbd in latest trunk.

The discussion might have continued from here.
