Intel 8265 wireless won't connect in ac mode [closed]

I am still trying to sort out everything on my new HP ProBook 450 G3. I removed the stock Wi-Fi card (rtl8723be) because it sucked, and replaced it with an Intel wireless ac 8265. Module iwlwifi is loaded and in use. I am connected to my 802.11ac wireless LAN. Several other devices in my home connect in ac mode without issues.

However, it only connects in b/g/n mode. From the router side, I can see the connection status as "Excellent". But I purchased the card to be able to use ac speeds.

Is there something I can do to configure the iwlwifi driver to connect in 802.11ac mode?

It looks like I need newer firmware. It fails to load versions 26, 25, and 24, then succeeds in loading version 22. I'm now looking for how to install the newest firmware in Fedora...

Ok, I have now determined that sometimes, it does connect with 802.11ac. It most often connects as b/g/n, though. This seems to rule out a configuration problem.

Also, according to , the latest mainline firmware does seem to be version 22, which is what my system is finally loading. I have no idea why iwlwifi is looking for versions 26, 25, and 24 first.

I am closing this question. It is weird to me, but it's like the new 802.11ac card had to train itself. With no changes by me, it started occasionally getting some poor ac connections, then more often and better connections, then usually getting good connections. Last night, I had a speed test result of 72 mbps, so I am satisfied.
