My ethernet cable from Tenda router to computer was working perfectly - approximately 25m long with rj45 both ends. I decided to insert a plug socket to neaten up the system at the router end. Checked the entire setup for continuity - no problem, when I connect any computer on other end the router port does not light up and no connection.
Please help this is very baffling!
