stuck with 802.11a?

P

So after reviewing thread 474727 I'm still stuck. I have a T470s with the Intel-8260, which is among the supported cards (iwm(4)).

I'm aware 11ac is not ready, but the card supports 11n, which as best I can tell is supported in FreeBSD, but I can't seem to get it initialize as anything but 11a.

I tried
Code: 
ifconfig_wlan0="mode 11n"
in rc.conf but nothing changed.

Can anyone suggest a way to get better bandwidth? I'm getting 20Mbps.
 
What's in your /boot/loader.conf as far as the firmware is concerned?
It should include
Code: 
if_iwm_load="YES"
iwm8000Cfw_load="YES"

Or maybe iwm8265fw?

I made your suggested changes: the 8000Cfw was incompatible and the device failed to initialize. The 8265fw initialized the device, but still didn't allow 11n connection.

I tried 11na but still got 11a. I tried "mode 11g" as a sanity check, and this did initialize the device in 11g mode, although there's no benefit to it of course.
 
And based on this email exchange there is no 802.11n support with iwm. How it's possible to call iwm a "functional" driver when it delivers 802.11a -- yes as in 1999, as in 21 f******* years ago, is a truly heroic act of inventiveness.

At least the OpenBSD driver page has the courtesy to note this jaw-dropping deficiency. What a waste of time this was.

Thanks to those above for your feedback. Moving on.
 
I don't know how you do it, but if people could complain to these closed-source hardware vendor perhaps they'd change their ways. While it's a pity FreeBSD doesn't support it, it's not FreeBSD's fault; it's these closed source hardware vendors protecting their rights (apparently)
