Wi-Fi clients cannot connect to each other.

[LeinsterSC]

I work in a school who today got a replacement router.

The new box seems to block Wi-Fi clients from talking to each other. In theory this is great security, but I need to be able to disable it, or make an exception for particular MAC addresses, so that the staff laptops can access the printers. Wiring these in is just not practical.

I’ve gone through the Admin interface but can’t see anything.

Do your printers have WiFi cards? If they do, then the laptops can print directly tro a printer.

At least they can in my house!

Might help to know what router ?   Also is this VM business router ?

Is it a LGFL site?

Hi Sephiroth,

If the printer is connected by ethernet and the latop by Wi-Fi; it works. If the printer is connected by Wi-Fi and the laptop by ethernet; it works, same for when both are on ethernet. The scenario that doesn't work is when both are connected by Wi-Fi. On the previous router there was no issue when both were on Wi-Fi.

My research has turned up a reference to "Wi-Fi NAT Isolation" as a configurable security feature on other brand routers that would cause this issue if enabled. I'm thinking something similar might be at play here but cannot see anything in the Admin interface that might be related to it.
