[Solved] WiFi speed is highly inconsistent with iwlwifi

This doesn't happen on my Windows install I previously had. This has been persistent through many reinstalls. My WiFi speed will go up to what it should be (About 50MB a sec) then down to around 10-15 and then back up, the whole cycle takes about 30 secs. This always happens no matter what I install. Happens with NetworkManager and without it, with wpa_supplicant and with iwd, with the zen kernel and with the regular one. I am using the iwlwifi driver that the kernel provides. Kernel logs show no errors.

ip link:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether REDACTED
3: wlp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether REDACTED

Do note that wlp6s0 defaulted to DORMANT, but changing this to default changes nothing

iw dev wlp6s0 info:

 Interface wlp6s0
	ifindex 3
	wdev 0x1
	addr REDACTED
	type managed
	wiphy 0
	channel 44 (5220 MHz), width: 80 MHz, center1: 5210 MHz
	txpower 22.00 dBm
	multicast TXQ:
		qsz-byt	qsz-pkt	flows	drops	marks	overlmt	hashcol	tx-bytestx-packets
		0	0	0	0	0	0	0	0	0

EDIT: Steam issue?

How was this solved?  It's not clear from the (edited) original post.

It appears my original testing that suggested that this happened in all applications was false. It happens in Steam, but I'm unable to reproduce in qBittorrent nor speedtests in Firefox.
