i found the problem i was on the wrong channel.
on inSSIDer i found more neighbours like 02 on channel 11, BT on channel 1, virgin on 6+10..
now i changed it to channel 10..working good only on 144Mbps
but find slow speed on 300Mbps and can't find a good channel to connect to.

so the problem is not OBSS sorry for disturbing you.
you was right about staying with 144Mb speed channels are more easy to find.

thank you for replying and taking your time to read and helping me.
thankz again
