WiFi 2.4GHz slow

spaarks — Tue, 26 May 2026 10:54:25 GMT

Sky SR203 Hub, installed this morning.

Fibre speed at ONT 150Mbps.

Split 24.4 and 5GHz.

2.4GHz set to ch6 where there are no strong interfering signals.

Only one device connected (phone).

Device tested 2m from router which is on top of a table.

Signal strength 43dBm.

FAST and Wifiman show around 35Mpbs. Latency 20ms.

I need to use 2.4Ghz, as TV and other devices I want to connect are not capable of 5GHz.

Surely I should be getting a lot faster than this?

PS PHY mode on Wifiman shows 802.11n with potential 72Mbps.

I should clarify that my problem was on the 2.4GHz band.

Anyway I bought a TP-Link Archer AX55, but very disappointed. It's signal strengths were considerably lower than the Sky Hub, and the downloads not very much faster. The AX55 has the advantage of allowing a lot more channels on 5GHz. The Sku Hub only allows only two - 36 and 44, which are overlapping.

I'm inclined to stick with the Sky Hub, but would be interested to hear from anyone who changed to the Sky MAX hub.
