Wireless N - RT/MTK21NOV USB адаптер

Tyler Pharmacognosy 9th Edition Pdf !exclusive! Jun 2026

USB Wi-Fi адаптер непонятной модели... естественно - из Китая. Очень дешевый, цену даже не скажу - не запомнил... Но пишу то, что есть. + Щелкайте по фото, чтобы увеличить!

Wireless N RT/MTK21NOV обзор Wi-Fi USB адаптера

Итак, пластиковый бокс, или блистерная упаковка. Устройство сразу видно через прозрачный пластик...

Wireless-N адаптер Wi-Fi модем, адаптер USB устройство

Вскрываем упаковку, внутри картонный вкладыш. На нем, на лицевой стороне: Wireless-N, USB Adapter. 150 Mbps. 2.4 GHz. USB2.0 Hi-Speed. IEE 802.11b/g/n

Wireless-N RT/MTK21NOV характеристики беспроводного адаптера

На обратной стороне техническая информация - характеристики и спецификации... Я не буду все перечислять. Вы это можете видеть на фото выше.

Wireless-N USB Adapter RT/MTK21NOV диск с драйверами

Картонный вкладыш складывающийся, в внутри маленький компакт диск, 80 мм Mini-CD, на нем записаны драйвера. Здесь драйвера под Linux, Mac и Windows - начиная с XP и заканчивая 10... На диске написано RT/MTK21NOV - эти адаптеры есть на чипах Realtek и MediaTek, поэтому там драйвера и на те и на эти устройства.

описание USB адаптера Wireless-N RT/MTK21NOV

Сам адаптер. Это небольшое USB устройство, похожее на флэш-накопитель. Отдельно идет накручивающаяся антенна.

проблема с установкой драйверов на Wi-Fi 802.11 n WLAN

Втыкаем этот адаптер в USB-порт, и сразу выскакивает сообщение... драйвера в Windows на него нет...

установка драйверов на USB адаптер для Wi-Fi Wireless-N RT/MTK21NOV

Устанавливаем с диска... Вот так в Диспетчере устройств.

Ну, в общем-то, все. Устройство работает, проблем никаких нет. Этот адаптер покупался не для ПК, а для цифровой DVB-T2 приставки. Там он работает без проблем. Можно работать и без антенны, в этом случае максимальное расстояние не более 15-20 метров. А с антенной 100 и более метров.

Вот так, почти ничего об этом адаптере... слов нет.

Wireless N - RT / MTK21NOV USB adapter

+ Click on the photo to enlarge!

USB Wi-Fi adapter of unknown model... of course - from China. Very cheap, I won't even say the price - I don't remember... But I write what I have. So, a plastic box, or a blister pack. The device is immediately visible through the transparent plastic...

We open the packaging, inside there is a cardboard insert. On it, on the front side: Wireless-N, USB Adapter. 150 Mbps. 2.4 GHz. USB2.0 Hi-Speed. IEE 802.11b / g / n

On the reverse side are technical information - characteristics and specifications... I will not list everything. You can see this in the photo above.

Folding cardboard insert, inside a small CD, 80 mm Mini-CD, drivers are recorded on it. Here are drivers for Linux, Mac and Windows - from XP to 10 ... The disk says RT / MTK21NOV - these adapters are on Realtek and MediaTek chips, so there are drivers for both devices.

The adapter itself. It is a small USB device that looks like a flash drive. There is a winding antenna separately. We plug this adapter into a USB port, and a message immediately pops up... there is no driver for it in Windows... Install from disk... Like this in Device Manager.

Well, in general, everything. The device works, there are no problems. This adapter was bought not for a PC, but for a digital DVB-T2 set-top box. There he works without problems. You can work without an antenna, in this case the maximum distance is no more than 15-20 meters. And with an antenna of 100 meters or more.

So, almost nothing about this adapter... no words.
