Hi, I have an RB3011 on my lan, before 6.41 it was all working without problems... after upgrading from 6.40 to 6.41 I have this problem:
ETH1 is WAN (PPPoE Client) - still working
ETH2 is 1st lan connected to an HP switch and an AP: RB3011---[hp switch (not managed)]---[AP Mikrotik wAP 6.41 in Bridge mode] WORKING
ETH3 is 2nd lan (same subnet) connected to an HP switch and an AP: RB3011---[dlink switch (not managed)]---[AP Mikrotik mAP lite 6.41 in Bridge mode] NOT WORKING CORRECTLY
Clients connected to the mAP have now extremely slow internet connection. From mAP terminal there is a packet loss of 99% pinging 18.104.22.168 and the DNS is not working. If I connect the mAP to the HP switch, it works perfectly. From the mAP (on ETH3) I can ping without problems all internal IPs (also if connected to ETH2).
The map has 1bridge with ethernet (root) and wlan associated. If I connect the mAP on the ETH2 then DHCP releases the IP to the ethernet mac of the mAP. Connecting on the ETH3 the IP is associated to the wlan mac-address of the mAP.
The strangest thing is that if I open form winbox the ETH3 properties and I click "TORCH"... when torching the mAP starts pinging 22.214.171.124, DNS works, internet is ok.
ETH2 is the root-port of bridge1, ETH3,4,5 are designated ports. With 6.40 (switch config) all was working.
Now I have downgraded to 6.39.3 and I reloaded the backup and all is working... so we can exclude hardware problems or misconfiguration of the mAP.
