Connecting two LAN´s P2P via repeater Bridges and trasnporting 4 VLAN´s, root´s located at each LAN and 2 non-root at repeater (Hill), I have intermitent IP connectivity even that int dot110 association is never lost and signal strenght is above 75%. This is the config for all radios (except for name and IP)and SSID´s are also different for each pair root/non-root. When this happens I shut/no shut the Dot110 interface or enable spanning-tree for default VLAN (1)at dot110.1 and works for a while.
IOS version 12.3(7)JA1 and 12.3(2) JA
Swithes 1 3560 configured as Trunk spanntree portfast trunk enabled (there a re no loops)
