The B4SH router is supplied by Genexis. This box is the all important Home Gateway that converts the Optical signals from the B4SH optical cable into data for your computer via Ethernet or WiFI.
If you have an existing BT / TalkTalk / Virgin router the Genexis box will replace that unit.
It is very easy to set up and it will get you on-line in no time.
