Старые замораживания ноутбука Toshiba после соединения с Wi-Fi; Ethernet хорошо работает (Ubuntu 14.04.5 LTS)

Я испытываю затруднения, заставляя Wi-Fi работать над моим старым ноутбуком Спутника Toshiba (приблизительно 2009). Ehernet хорошо работает, но если я разъединяю кабель и компьютерные подключения к Wi-Fi, машина всегда заканчивает тем, что заморозилась 1-2 минуты спустя. Wi-Fi, кажется, работает хорошо иначе, поскольку я могу просмотреть Интернет, пока все не замерзает, и я должен перезагрузить компьютер.

Я выполняю Lubuntu (Ubuntu 14.04.5 LTS).

Вот ссылка на мои сетевые спецификации:

Я должен упомянуть, что работал

     sudo apt update
     sudo apt dist-upgrade

прежде, чем отправить по этой проблеме.

Кроме того, если это полезно:

Я вижу, что существует repo для новейшей Realtek rtlwifi коды GitHub (https://github.com/lwfinger/rtlwifi_new), однако я не уверен, решило ли это проблему или как установить надлежащий код.

Я - новичок к Linux.Спасибо за помощь!
