Deco X50 access point Both with LAN, one goes very good, the second very bad
Today I changed provider, with a new modem tplink 830v supplied to me by Wind Tre (italian provider) with the FWA ethernet connection, that is quite good: the modem speed is around 250mbps.
the house is very large and extensive, and I wired the two sides of the house and placed two Deco x50s set as access points, both connected VIA LAN (identical LAN cables) to the Tplink 830v modem, I can't connect the deco via LAN each other, because the LAN is centered to the router.
The main Deco has a wifi speed equal to the modem of approximately 250mbps, while the second Deco (also in LAN) has a speed equal to 20mbps. Rebooted and reset several times, I also tried to reverse them, but only one always remains very slow.
the modem's LAN settings are standard, but I only prioritized the Ip of both Deco and left them static IP.
I also excluded the main modem's wifi, without any change.
Please let me know if I can do something, before I launch to the sea!
Many thanks for any idea or solutions!
