I have two PCs. Intel Pentium4 2,4GHz, with mikrotik R52 radio, installed mikrotik 2.9.51.
I have turned on WDS bridge and Nstreme, but then the cpu usage is 20%, and the brigde is not transporting traffic.
when I turn off the wireless interface the cpu usage is going to 0%. with bandwidth test the cpu is 100% used.

and the graphing is weird - there is a holes, everything is going ok, and suddenly appears a hole.
