Slow download speeds Intel 8260 Wifi Adapter

[techguy378]

I have an old System76 laptop with an Intel 8260 Dual Band Wifi 5 adapter. For some reason when I do a speed test at "speedtest.net" I'm only getting download speeds of 3mbps. On Ubuntu Linux 23.04 when using the same server I'm getting download speeds of 850-900mbps. Also, GhostBSD won't connect to 5GHz wifi networks, it only connects to 2.4GHz networks. How do I fix this?

My system config:

Intel Skylake Core i7-6700HQ processor
Intel HD 530 Graphics
16GB RAM
500GB Western Digital SN750 NVME drive
Intel 8260 Dual Band Wifi Adapter

Manually issue the wpa_supplicant CLI command with the background Dameon option and dhclient commands

killall dhclient
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
dhclient wlan0

For Debugging,  Use the following line for testing with the Debug and Password debug printout options
killall dhclient
service netif restart
service routing restart
wpa_supplicant -d -K -i wlan0 -c /etc/wpa_supplicant.conf
dhclient wlan0

Problems running dhclient? Then kill the previously running dhclient.

killall dhclient

dhclient wlan0
