Why Your Wi-Fi Is Slow (And What Actually Fixes It)
The provider says the line is fine, and they're usually right — in most small offices the broadband isn't the problem, the Wi-Fi is. The two-minute test that separates them, the four real causes, and what a proper fix costs.
The short version
- Speed test wired into the router, then over Wi-Fi where people sit — that one comparison tells you which problem you have
- Full bars means signal, not speed; a wall costs you more than distance does
- Extenders repeat on the same airspace and can halve your capacity while showing more bars
- Business access points run about £79–£140 each (roughly $100–$180), and wired beats any wireless repeater
