5ghz wifi (Intel Corporation Wireless-AC 9260) streaming 720p @ 3.5kbps

More of an FYI, kinda weird but not really stopping me from doing anything. Any insight would be interesting.

Recently had to get a new WiFi card, my old one took a - - - -! Picked up an Intel 9260 off Amazon for cheap.

At first (i.e. Fedora 30) it would see 2.4ghz and 5ghz and connect to either, but on 5ghz the connection would be soooo slooooow it was literally dial up speeds. No worries, I just used 2.4ghz and went about my business.

After each significant update, I’d re-connect to the 5ghz to see if anything would change just for curiosity. Nothing ever changed, until this morning [edit: now on 31 beta].

As the title says, now if I connect to 5ghz, while streaming a 720p video on YouTube, Gnome System Monitor shows a DL rate between 3k and ~8K (like before), but the difference is the pages (and video) actually load and play no skips. Prior to today @5ghz if the system monitor showed atrocious download rates, my web experience reflected that (ie. bing.com would take a full minute to load and playing a YT video was impossible).

Again, any insight would be cool, but not really a show stopping problem.

Connect to the 5gHz and post the output of:

iw <device> link

where device is, e.g., wlp3s0

$ ip wlp6s0 link
Object “wlp6s0” is unknown, try “ip help”.

Not sure what you’re after. If I just “$ip link” I get:

: wlp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
link/ether 5c:87:9c:66:58:a5 brd ff:ff:ff:ff:ff:ff

That is weird. On my system, it tells me many stats about the connection, and I was looking for the actual connection speed. I usually run the command as root, but I don’t know whether that why it’s not working for you.

The command is “iw”, not “ip”.

Reading (I can do it). iw makes more sense, lol.

rx bitrate: 390.0 MBit/s VHT-MCS 4 80MHz short GI VHT-NSS 2
tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2

That is showing a higher rate than Gnome System Monitor.

And that tells me that you have a full speed 802.11ac connection. Whatever the problem is, you need to look elsewhere for it.

You could try keeping a terminal window open, and running that command whenever you are actually experiencing your problem, but I really think the wifi connection is not the problem.

what GSM or NetworksManager shows is not always the (full) truth.
acer notebook wifi cards (QCA9377) are shown with 6 Mb/s in NM, but the wifi router tells a connection at full speed.

so look at your wifi router /access point too !
