Deco M4 constantly drops internet connection
My router constantly drops internet connection while WiFi is still active. The easiest way to get critical issue is to run a speedtest and multi upload. However multi download works well. Tried that on a factory firmware and latest firmware with the same luck.
Here's error log from deco:
