Hello guys please help me find a solution

thanks in advance

OpenWrt does not support the wifi chip in that model. It can be used as a wired router only.

so i can't use it as wireless repeater?

Not with OpenWrt. Have you looked to see if there is dd-wrt for it?

  • dd-wrt is an entirely separate project from OpenWrt and sometimes they have better support of Broadcom hardware.

thanks for your help
but dd-wrt doesnt support Comtrend unfortunately, i have like 4 routers all of them are fibre but unsupported devices
