Hi.
If in wire network didn't have a problem, for example, you didn't have problem with wired cable quality and use 1 Gb/sec Ethernet interface, then the problem in wireless device, in used Wi-Fi standards. If you want via wireless also have 700 Mb/sec, firstly you should use the at least Wi-Fi 5 devices (5 GHz - 802.11ac standard - point to point bridge connection), but for comfortable using you should use W-Fi 6 devices (802.11ax standard). And that there be no "barriers", like thick walls.
I am working remotely and at the present stage (at this time) I am communicating via chat/message only.
If it is not a problem for you I will be glad to cooperate.
Thanks.
