Deco M4 low wifi speed when getting away from main Deco
Hi,
I recently bought M4 mesh system. I have a fiber internet connection at 500 Mbps up&down. I have a black box that has a fiber cable plugged-in and an ethernet cable plugged-out to the Internet Box (Proximus in Belgium). I tried to plug in the ethernet cable directly to the Deco itself (from fiber box to deco). Unforunately, I could not managed to connect to the internet with this method. Afterwards, I connected my Deco to the Internet box (which is connected to fiber box by an ethernet cable in WAN port) via ethernet cable and now it works.
When I am close to the main Deco speed is 400 Mbps, perfect. However, when I get away from the main Deco and get close to the slave Deco in downstairs, speed goes down to 100-120 mbps.
I tried switching to AP mode as well as setting the slave Deco downstairs as main Deco (which is I'm close to) and no chance. I also tried enabling/disabling Fast roaming, beam forming, NAT forwarding etc. (did not reboot the modem in the meanwhile though) Qos is set to 500 mpbs for up&down.
Any idea or solution for this?
Internet if full of speed problems but in my case I actually have very good speed in close range to main Deco. My main problem is low speed near the slave Deco.
I bought this product because internet speed was too low in downstairs that speed was very low. Now, I have a nice signal but the speed is still low :(
Regards.
Edit: I always make the speed test while connected to 5 GHz band.
