I am in the cctv business and often have to run an ethernet cable from a dvr to the router and use port forwarding. Occasionally it has been impracticable to run a cable so I have been using a lynksys gaming adapter connected to the dvr. This works perfectly but I am sure there is something else I can use. I have stood in the pc world networking section and looked at access points etc. but it aint my thing!! Is there anything I can use as an alternative?? Thanks.
