Deco M4 slow wifi speed!
Hi there!
I am new on this forum, but after having read a lot and tried a lot, I would like to ask my question here.
Recently, I purchased a TP Link Deco M4 set woth 3 Decos. I closely followed the manual and other information I found online and on this forum.
When connected to the Decos over Wifi, I only have download speeds of around 20-30 Mbps, sometimes even lower. The maximum speed of my ISP subscription is 500 Mbps. The speeds are always this low, regardless of the device I use, regardless where I stand in the building. Even when I am standing right next to one of the Decos.
I have connected all my three Decos via an UTP cable as follows:
Modem --> Deco 1 --> Deco 2 --> Deco 3.
All Decos are in Access Point mode, like the manual says.
The Decos are placed on different levels in the building, but the UTP cables in between are always short (max. 2 meters). I use brand new UTP cables, CAT5E.
Firmware of the Decos 100% up to date according to the app. I have reset the modem already couple of times, also I have rebooted the Decos a couple of times already. Nothing seems to work to increase the download speed.
When I connect my laptop directly to the modem with an UTP cable, I reach 500 Mbps download speed. The modem does not seem to be the problem. I do the speedtests with the Ookla Speedtest app or website. 5 GHz is turned on, 2.4 GHz as well. Who can help?
P.S.: my entire building is equipped with a UTP network with wall sockets everywhere. Would it help to connect the Decos separately to the UTP sockets in the buildings and place them more strategically throughout the house? Is that possible and allowed in access point mode?
