dir-615 c2 wifi disappeared

Question

WiFi

Hello, dear habrousers!
Today I decided to flash my dir-615 with dd-wrt firmware (DD-WRT v24-sp2 (08/07/10) std), it was successfully flashed, but the wi-fi LED was not on and there was no wireless item in the admin panel.
Googling came across this:

WARNING TO ALL OWNERS OF DIR-615 C2
After firmware on 03-17-11-r16454 KILLS WiFi!!!
They bring us to the service to reanimate. To be treated only by resetting and firmware through the programmer.

Maybe someone came across this or in which direction to dig?

Answer 1

Don't you believe the warning?

Answer 2

And resetting 30-30-30 and flooding clear + recover + standard factory firmware does not help? I solve all serious problems with wl500 like this)
