Hi,
I have subscription for 1 Gbit up/down. I have 3 Deco M9 Pluses used in AP mode, all wired. All wires are Cat5e. T-Mobile modem is directly connected to the main Deco. I also have ethernet connection from Deco to my PC. A few days ago I noticed an abnormal slow connection speed. When I tested over speedtest.net, I got 160 mbps tops. I tried to reset the modem and the bridge. Resetting Decos did not work either. I noticed, on the community forums, that recently there is a general problem and seems like my problem also has started by then.
I tried resetting everything in my network, disconnected all the other devices, etc. Nothing worked. I used to get around 800, 900 mbps but now it is 160 mbps no matter if I test wired or wireless.
Regards,
Ersin
