10BASE-T does not specify the exact type of wiring to be used but instead specifies certain characteristics that a cable must meet. This was done in anticipation of using 10BASE-T in existing twisted-pair wiring systems that did not conform to any specified wiring standard. Some of the specified characteristics are attenuation, characteristic impedance, propagation delay, and several types of crosstalk. Cable testers are widely available to check these parameters to determine if a cable can be used with 10BASE-T. These characteristics are expected to be met by 100 meters of 24-gauge unshielded twisted-pair cable. However, with high-quality cabling, reliable cable runs of 150 meters or longer are often achievable and are considered viable by technicians familiar with the 10BASE-T specification.
Роутер 300Mbps,. Порт на ноуте также 300. Уровень сигнала везде сильный, эфир почти чист
Не лагающие протоколы передачи экрана (для работы с графикой), требуют минимум гигабитные сети и алгоритмы, кодирующие изображение видеокодеками.
Простейший vnc не подойдет.
Хорошую скорость могут дать к примеру майкрософтовский rdpx (только с серверными ревизиями windows, только с прямым доступом к серверным видеокартам), или что то типа teamviewer/anydesk, попробуй parsec, так же мне очень понравилась работа steam link remote play (бесплатно, win/linux, заточена на realtime игры, и клиенты могут работать на очень старом железе, например планшетниках android, т.е. поддержка очень качественная, хотя что то я не уверен что какая-нибудь малинка тут справится).
Открытые решения - например sunshine+moonlight (говорят лучшая замена steam link), rustdesk
