Hello.
My Wi-Fi at home is not the best at the moment. The house is a two-story family house, which will soon (almost) double in floor area. (ground floor is concrete/brick, first floor is light structure)
At the moment, the networking looks like this:
ISP [500Mbps/23Mbps service]
ISP modem: Sagemcom FAST3686 with ISP custom fw (DHCP on, WiFi off)
TP-Link Archer C8 (DHCP on, WiFi: 5G + 2.4 GHz on different SSID) [ground floor]
TP-Link 5-port gigabit switch
1 PC, 2 STB, 1 Smart TV
TP-Link 8-port gigabit switch
TP-Link TL-WR740N (DHCP off, WiFi: 2.4 GHz on same SSID as the Archer) [first floor]
2 PCs, XBox, NAS, 1 STB
The connection is slow on the first floor, and I think the two routers are conflicting.
My family uses 5 phones, 1-2 notebooks, a Chromecast, in addition to the above devices.
My question is which brand do you recommend in wireless networking?
I am considering using a mesh system, and these are my options:
Strong Wi-Fi Mesh Home Kit 1610 (3-pack) [https://www.strong.tv/en/products/wifi-mesh/homekit1610]
Looks okay, tempting because my ISP sells a 3-pack for ~65€, and that's a really great price.
TP-Link Deco M4 (3-pack) [https://www.tp-link.com/en/home-networking/deco/deco-m4/]
I would prefer this, but this is much more expensive, the 2-pack is 95€, the 3-pack is 145€.
The renewal of the house is about 1 year away, so my preference would be to buy a 2-pack Deco M4, and later buy a third one.
What are your recommendations building a wireless system?
Thanks.
