internet problem with packet timeout

hi,

now i have another problem.

main RB with internet(10.11.10.250) is connected trough wireless link to another point where also VPN server is started (10.11.19.250)

on this point are like 10 VPN clients and all have the same problem…the example client on the picture is 10.11.19.76

10.11.10.250 - point1
10.11.19.250 - point2
10.11.19.76 - client

P1>P2<>client
ping P1<>P2 avg 8ms no packet loss
ping P2<>google 40ms avg no packet loss
ping client<>P2 2ms avg no packet loss
ping client<>google 60avg packet loss 11% and on the busy hours the ping is like 100ms avg and packet loss like 30%

i have found alot of topics on this matter but just wanna open another one and maybe someone post the result that i dont have to read for weeks
