I recently bought the Deco M4 (V2) 2-Pack, I'm using them as a router and I set it up using custom cat5e cables and backhaul. I am paying for 100/10 internet and I am reaching the advertised speeds over both ethernet and wifi. But. When I move close to the second deco and the change occurs, I do a speedtest and it is only 30/10. If I turn on and off the wifi on my phone it goes to normal (100/10). If I go close to the other one and it automatically connects again, it goes 30/10. What is happening. I have also tested it with ethernet and it is always 100/10 even when on the phone it is 30. I use multiple speedtests, including the tp link app "Wifi Toolkit".What is happening? Is it the phone?
