Solving the problem with freezing DIR-300/NRU/B7 using firmware from Zyxel Keenetic Lite

I noticed on more than 10 DIR-300 / NRU / B7 routers that they hang periodically, the Internet disappears, and if the router is included in an unmanaged switch, then the DIR-300 / NRU / B7 also hangs it. All official firmware up to 1.4.8 did not solve the problem.

It was possible to solve the problem only with modified firmware from Zyxel Keenetic Lite.
