OC200 with ER605 after the update from 2.2.3 to 2.2.4 hangs ups every 2-3 days. Downgraded to 2.2.3. It looks like 2.2.4 is very bugly and no information on the websites. You can see the difference after downgrading on the stats for CPU and memory image. Why there is no hardware watchdog in the device to reboot it in case of issues automatically? 

TP-Link Team @Fae  - when do you plan to start doing stable releases and not anymore experiment with production systems and clients? Create release channels, please. See and compare how other brands and competitors are managing updates. 

After three times for the last week driving a few hundred km to reboot the router, I'm considering during the next hang up and next visit to completely switch equipment to another brand.
