Have you the new EE green firmware not the Orange firmware? I cannot see any reference to 2.5 GHz wireless speed/frequency in my router. Below is from the router help.
Channel and SSID
The Bright Box Wireless router supports 3 wireless modes:
802.11n - this will only allow wireless adaptors supporting 802.11n to connect to the router
802.11b+11g - select this if you're using an older wireless adaptor or software that only supports WEP
802.11b+11g+11n - use this if you want to connect 11b, 11g and 11n devices to your network
By using 802.11n or 802.11b+11g+11n the router will support up-to 300Mbps speeds on your internal wireless network when used with a compatible wireless adaptor. 802.11b+11g will limit the connection speed up to 54Mbps.
The channel is the radio channel used for wireless communication. By default the router will automatically select the channel with the least interference in your area. If you'd prefer you can select your own channel between 1 and 13.
Note: Setting the Wireless Channel or Extension Channel to 12 or 13 may sometimes cause compatibility issues with some wireless devices.
Setting the bandwidth of the wireless connection to 20/40MHz allows you to double the speed of your internal wireless connection from 150Mbps to 300 Mbps. The router will automatically select an extension channel for use by a compatible wireless adaptor to dual bond the wireless connection. For channels 5, 6, 7, 8 and 9 you can choose whether the extension channel is from a lower or higher frequency range to help avoid interference.
The Bright Box router has a great feature called 'Intelligent Wireless'. When starting up the router, it will automatically search for and use the least congested Wi-Fi channel, reducing the effect of interference, and providing you with the best wireless performance.
Pressing the Intelligent Wireless button on this page will activate the Intelligent Wireless feature without having to restart your router. It will re-check to see if the router's using the least congested frequency and change channel if required. The current Wireless Channel is also displayed here.
You can also activate Intelligent Wireless by briefly pressing the WPS button on the back of the router.
