what Aaron said.
There is no 'answer' to your question, as the real answer is .. it depends.
if you want reliable, consistent, drama-free experience, avoid WiFi. period. Seriously... I temporarily ran a 200ft Ethernet cable for a while (3 years ago... can you believe). a USB to Ethernet adapter is cheap, if your laptop doesn't have a built-in Ethernet post, or you don't have a dock with an Ethernet port.
And do NOT try to sending video from camera to laptop via wifi, then real-time video composite (subject to thermal throttling), then send video out again via WiFi...
if you must use WiFi, then you have to consider AP, SSIDs, signal strength, other users, quality of service settings, etc. Possible approaches with WiFi depends on whether using consumer vs business class Access Points, which WiFi version, and the settings you have access to configure (ex VLAN capable setup, QoS options, etc).. sound complicated? for non-network engineers, it can be (doable for the IT sophisticated, but well into the geeky weeds)
