[Solved] Gnome and NetworkManager show wrong WLAN connection speed

I am using Gnome as my DE and use NetworkManager as my connection manager (as is the Gnome standard). Now, whenever I check my wireless connection speed to my home network, Gnome settings tells me that the connection speed is 6 Mbit/s. However, speedtest gives me 73down/36up connecting the the larger interwebs and my modem thinks my connection speed is 866/526 locally.

So, why is Gnome/NetworkManager so confused and how do I fix this?

Re: [Solved] Gnome and NetworkManager show wrong WLAN connection speed

What are the output of iw wlo1 link    ? (Replace wlo1 with the name of your wireless NIC)

Re: [Solved] Gnome and NetworkManager show wrong WLAN connection speed

[gunnar@alien-arch ~]$ iw wlp61s0 link
Connected to e0:28:6d:47:fb:79 (on wlp61s0)
	SSID: [censored]
	freq: 5180
	RX: 170485317 bytes (331428 packets)
	TX: 11658817 bytes (63959 packets)
	signal: -49 dBm
	tx bitrate: 6.0 MBit/s

	bss flags:	short-slot-time
	dtim period:	1
	beacon int:	100

So it seems that it's not Gnome that's confused, but rather iw?

Re: [Solved] Gnome and NetworkManager show wrong WLAN connection speed

That was my hunch.  It seems to be the source of the information.
But, the real question is, which is the the lie?   Frankly, I am inclined to believe iw

On my system:

ewaller@turing ~ [1]1013 %iw wlo1 link
Connected to d0:17:c2:60:24:5c (on wlo1)
	SSID: Woodlyn-hi
	freq: 5220
	RX: 7536503 bytes (20951 packets)
	TX: 1262031 bytes (7343 packets)
	signal: -44 dBm
	tx bitrate: 433.3 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 1

	bss flags:	short-slot-time
	dtim period:	3
	beacon int:	100
ewaller@turing ~ 1014 %

And www.speedtest.net reports 116M/11.3M (I pay for 100/10).  Of course, my 433Mbit/s is the link to the router.
What are you using as a speed test?  What if you try the speed test I linked?

Re: [Solved] Gnome and NetworkManager show wrong WLAN connection speed

I've previously used speedtest-cli from [community]. The link you provided gives me 94.12M/34.48M (I pay for 100/50, but I share with the rest of the family). So maybe iw is wrong with my hardware?

Re: [Solved] Gnome and NetworkManager show wrong WLAN connection speed

And Bingo: It is a bug in my firmware! See here: https://wireless.wiki.kernel.org/en/use … imitations

Thank you for helping me figure it out, seems that Gnome is really not to blame here. Unfortunately, that also means that there does not seem to be an easy fix.
