We've been provided a wireless bridge solution, however it doesnt appear to be working for us. As usual, they sell us the product then when it comes to problems they just handball it to tech support.
We called tech support and they need to investigate it.
The solution was 1st pair from building one to building two, then another pair from building two to building three. Bassically in building two there is a managed switch that connects the access points to pass the traffic through, however when they are both connected, wireless connection loses connection. If one of the access points on the switch is disconnected with POE injector added, the wireless connects no problems at all.
It appears that when 2 access points connected to the same switch, it conflicts. And I cant find any guide regarding this particular setup.
Anyone with some experience, please advise.
