A total of 44% of the devices operating in the 5GHz range were able to provide decent speeds at 50 metres away, whereas a majority in the 2. 4GHz band performed poorly at 50 metres and some ceased to offer a wifi connection entirely.
In December 2018 and January 2019, big brands including D-Link, Linksys, Netcomm, Netgear and Billion were tested for performance on the NBN via cable connection, then on wifi, between 5 metres and 50 metres away from the device, as well as through walls or other obstacles that can interfere with wifi performance.
Enex found that wifi networks in surrounding apartments and houses with their own wifi networks can interfere with speeds on the devices, but interference causes more problems in the 2. 4GHz band.
She said this is something consumers should be informed about. “Telcos and modem suppliers need to provide good advice to consumers about the features and performance of individual modems, especially wifi performance,” she said. “Consumers should also ask their telco about the performance they can expect from the modem supplied to deliver their service.
Acma chair Nerida O’Loughlin said that when connected via cable to the NBN connection many of the devices performed similarly, but the results varied wildly when switched to wifi.
Slow NBN speeds: modems partly to blame for poor performance https://t.co/0iERGxHy8a— Guardian Tech (@guardiantech) July 5, 2019
