Virgin Media has challenged a BT Total Broadband advert which pushed the advantages of the 802.11n capabilities of latest version of the BT Home Hub.
"Virgin Media Ltd, who introduced an N router and USB adaptor with their 50Mb service on 15th December, challenged whether the claims "Unbeatable wireless connection compared to other UK broadband providers" and "No other UK broadband gives you a better wireless connection than BT Total Broadband" were misleading and could be substantiated."Complaint from Virgin Media
The complaint was not upheld by the ASA, with the decision being based on information from BT and the Wi-Fi Alliance. The ASA also felt the advert was clear that it was referring to the speed of the wireless LAN connection, rather than actual internet access speeds.
While 802.11n will generally give better coverage or higher speeds to people who use an appropriate 802.11n adaptor on their computer, people trying to connect devices such as the Sony PS3 with its built in 802.11g will not get any major benefit. Some Virgin Media XXL customers are also finding that the 802.11n devices can give highly variable results, which suggests the lessons learnt from the use of 802.11b and 802.11g still apply, i.e. that to get the best speeds you need to use Ethernet cabling around a property, or utilise other options like HomePlug devices. In urban areas the number of wireless networks can also result in congestion, and if your wireless is slow it is worth experimenting with changing the wireless channel used by the router.
