Fortigate Wireless Display

I want to do wireless mirroring from laptop to TV in the organization. but the connection is constantly dropping. Or there is a lot of loss. This does not happen when I try on a different device. What settings should I look for in the firewall for broadcasting?

Wireless mirroring (at some decent quality) over the network router will always have a lot of latency or hickups. Even with a couple of different vendors I saw the same behavior. My solution was to add the TV and and the AP on the same LAN (communicating only through a GB switch, bypassing the FG). This works decently for HD quality, but when it comes to anything higher, there are again some hickups.

What to check on Fortigate

> make sure you're using a unit that can sustain the traffic. I would suggest 100-series and up. 

> remove any UTM filter on the policy that allows the traffic

> set the policy in flow-based mode

> remove NAT (if possible)

Additionally, if more traffic is passing the unit, you can test implementin traffic shaping and prioritization QoS/ToS
