TP-Link Deco M9 | Dramatic low speeds on satellite Deco's
Dear All,
Would someone please suggest what to do to solve my very slow deco 2 and deco 3 speeds?
After yesterday's installation, all seemed OK: Green lights on all decos. 300 Mbps download on the basement. However on the 1st floor and on the 2nd floor (both floors with their #2 and #3 own deco) the speeds are dramatically low: On the first floor I am at 10Mbps only..... ;-(( Situation: Router/Modem from my internet supplier (Ziggo in The Netherlands). Basement deco #1 is connected with internet cable. Reading the forums, I disabled UPNP and SIP ALG. I also tried switching to Access Point modus, but that did not help either. I moved the deco's around... still bad speeds. Surely, I am doing something wrong. Please kindly advise. Thank you so much!
Kindest regards.
