Poor WiFi range signal

[Mkg4]

I recently got the sky 2.5 gbps gigafast+ plan and next to router I'm getting around 600 Mbps however when I'm upstairs I get very low speeds under 25 Mbps. I'm in a 3 story house and even with our last broadband provider we had issues with WiFi signal which is why we changed but the problem stayed. Anyone know what to do very poor signal on second floor and on the 3rd floor signals so bad siblings gotta use mobile data. If anyone could help would appreciate it.

@Mkg4 your Gigafast+ service includes free WiFi Max (https://www.sky.com/help/articles/sky-wifi-max) which mesns if you call Sky they should send out a WiFi extender. . You can get up to 3 extenders but the additional units requirecan dnginerrcto visit and approve the need.

To get speeds over 1Gb/s in areas near the hub you would nedd a device which supports at least WiFi6 or better WiFi7 getting 600Mb/s implies tge device only supports WiFi5.
