I recently installed the new Deco M4 2 pack mesh system and I noticed a issue that I do not have on the previous router. When I test the speed on speedtest.net, fast.com and others, I reach the maximum speed after around 10 seconds. For example, the speedtest starts at 500mb and after 10 seconds it reaches 900mb. On the old router, it is starting from 900mb from the first second.
I performed several resets, I changed the main device, I use the last firmware, but the issue is still there. Can somebody help me?
