I agree.
Wireless is just not cut out for _general_ LTSP use. You might find
some limited success for things like kiosks running everything as a
localapp but the use cases are relatively niche.
I have moved most of my clients to switched wired 1000 Mbps connections
because even dedicated 100 M connections were too slow for some things.
Also keep in mind that the apps that use a ton of bandwidth might not
be obvious. LibreOffice Impress was one of the applications that was
frequently unusable at 100 Mbps.
