I have a Linksys WAG320n that im no longer using - been using it for my Sky Broadband up until switching to BT for Infinity (area is soon to be upgraded)
Although i believe this can also be used for BT Infinity aswell, as one of the ports can be used as a WAN port. I'm just sticking with the provided BT router atm.
Mine is the all black one as in the Linksys product details.
Wireless N -Dual Band
4 port Gigabit Hub
USB Port for Network Media Sharing/Streaming
All in great condition, comes with micro filter, network cable and phone cable. Don't have the original box though.
£60 inc delivery.
