wifi adapters

Because I am using an antique desktop (Dell Optiplex 960) and WiFi, I am stranded at linuxCNC 2.7.15.  I have struggled to get decent network speed.  Only some USB WiFi adapters work native to 2.7.15.  (Trying to install drivers for adapters with other chipsets was more effort than it was worth.)  The SMC EZ Connect works, but it is only 802.11g and because there is a range and refrigerator in line of WiFi to router, I was limited to about 16 Mbps.

I decided to take a walk on the wild side and bought a BrosTrend Linux USB WiFi Adapter AC1200 for Ubuntu Kali Mint Debian Kubuntu Mate Zorin PureOS Raspberry Pi Windows etc. Linux Compatible WiFi Adapter Wireless Dual Band 5GHz 867Mbps + 2.4GHz 300Mbps.  Once I followed the instructions at linux.brostrend.com/ I was able to install the drivers for what is apparently the AC1L family and now I get 240 Mbps. Customer support was necessary to figure out which driver family was required during driver installation.   Curiously, plugging the adapter into the front USB ports gave me many times the rate as rear USB ports.
