BT has been forced to pull a TV advert for its new Home Hub 4, because it misled customers about WiFi interference.
The ASA (Advertising Standards Agency) has ruled that the ad had misled viewers about the sources of WiFi interference.
The new Home Hub 4 is a dual-band wireless router that transmits and receives data on the 2.4GHz and 5GHz frequencies. Devices like baby monitors and microwaves can interfere with WiFi signals in the home.

While it’s true that the Home Hub 4 can use the 5GHz band to send and receive data if there’s congestion on 2.4GHz, the advert appeared to suggest that mobile phones caused WiFi interference as well.
BT referred the ASA to a 2009 Ofcom report that concluded that household devices were the main cause of WiFi interference.
Further clarification from Ofcom revealed that mobile phones did not create interference and so the Agency ruled that BT must not broadcast the advert again in it’s current form.
