Damn. I just wanted to start a blog and left it alone after the introduction post. It’s time to return.
TP-Link continues to migrate onto the new Mediatek chipsets. They’ve released new versions of two popular routers recently: WR841N and WR840N.
Some guy called svobodavac made a patch for wr840n v4 initial support by LEDE. That pull request was declined by LEDE and was temporary closed.
Unfortunately, the mt76 wireless open-source driver is not able to provide a stable wireless connection. With this driver I had continuous disconnects, missing beacons, packet loses, low power signal (this was fixed with new EEPROM location in dts). I don’t know if it works or not properly for all mt76xx devices or just mt7603.
So I decided to build LEDE with a proprietary MTK driver.
