I’ve had no issues with USB. I use Gentoo on all my Pi’s. I use USB for bluetooth, WiFi & as the root partition (USB storage). I’ve used at least 5 x brands of USB WiFi adapters. I’ve pretty much standardized on “<span style="font-family: Menlo; font-size: 11px;" class="">Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]</span>” as of late, but I’ve used other chip sets (from Amazon for < $10).

I’ve not been able to track this down to a chipset or USB specific (it happens on the Pi 3, with built-in Broadcom WiFi). All my scripts that automate things with my Pi’s that are on WiFi, start with a “<span style="font-family: Menlo; font-size: 11px;" class="">ping -c 4 -q $host</span>”. ALWAYS by the 4th ping, the Pi is responding. With the Ethernet, always by the 2nd ping, the Pi is responding.</div></body></html>
