Hey, I am having two problems. I have successfully managed to install OpenWRT with Dielee's files (Thank you!).
Unfortunately the wifi is really unstable for me. 5GHz seems to be fine but 2.4GHz looses internet connection quite often and sometimes drops completely (not appearing in available networks anymore at all).
After fiddling around with it a bit with no success I decided to just go back to stock. But with that I am also out of luck for some reason.
I can't get it installed through TFPT, it takes the firmware file but doesn't boot up afterwards. Installing through Luci ended up the same way for me.
Does somebody know what I am doing wrong? (Disclaimer: I am far from knowledgable, so I might be doing things the wrong way to begin with.. :D)
