I have two WRT1900ACS routers. One after installing the ww-drt firmware works great. The second one has No Wireless selections available after installing the same firmware.

Any help would be appreciated?

Probably needs a reset and re-configuration.

Please post in the Marwell forum for this unit.

HI,

I recomend you use a last build (34929), boot in stock partition and install ww-wrt factory, and config your network.
I'm use same router and all works!

As I mentioned in my original post. I have two WRT1900ACS routers. One works great. The second, I have rebooted and reinstalled the firmware, but still no Wireless menu is available. I think I have the lasted firmware, but where can I download the lastest firmware in case I don't have the lastest.

that’s a good one. Bad flash perhaps? erase nvram and flash it again and take the reset to default option. Since there are a few different 1900’s confirm you have the correct firmware for your model.

Thanks for your help. But I had to erase the nvram and flash it several times before the wireless came back and started working.

Now today I had a power failure and the wireless stopped working. It says radios are off. I have not found how to turn them back on.

And suggestions, I really don't want to go through erasing the nvram again.

If you go to the wireless tab/ basic tab you will see Wireless Network Mode pick disabled from the drop down menu then scroll down to the bottom of the page and apply settings, after doing that go back in and switch back to your previous settings.

Also remember to do this with all three radios and most folks disable ath2 radio.

hope this works for Ya.

Edit: not sure it the 1900ac has 3 radios if not disregard the ath2 radio statement.

Thanks for the info, as it's not really obvious how to turn the radios on and off.

But this did not solve the problem.

So I restored my backup file which did work and everything is working ok again.

Thanks
