Because the ubuntu1804 installed on the company's development computer needs to find a USB wireless network card with good compatibility and mainstream. From Jingdong Taobao, we purchased more than 30 types of mainstream and portable USB network cards in the market, and came back for evaluation, covering all the solutions of mainstream wireless manufacturers.
At present, there are five major wireless chip manufacturers: Qualcomm, Intel, Broadcom, Realtek, and MediaTek. In addition to intel, other companies have corresponding USB products. Qualcomm released the least number of USB network cards, but it has the best performance and compatibility stability, followed by Broadcom. MediaTek and Realtek have the most USB wireless products, especially Realtek. At present, 90% of the products on Jingdong, Tmall and Taobao use Realtek RTL8811CU and RTL8812BU solutions.
In terms of the compatibility of ubuntu free drive installation of USB network cards, except for Realtek, other companies basically support them all.

The form made cannot be copied and edited, and the information could have been improved.
The final cost-effective recommended solution: cheap Broadcom BCM43236 (600M) and MediaTek RT5572 (600M) dual-band, more SSIDs to choose from, good signal, high bandwidth, moderate size, the most important thing is the installation-free driver under UBUNTU.
For the pursuit of bandwidth, you can choose: MediaTek MT7612 (1200M) dual-band, the price is relatively high, and the only 1200M free drive product on the market.
If the pursuit of stable bandwidth is not high: cheap, small size, and drive-free MediaTek MT7601 150M 2.4G is also a very good choice.
