FreeBSD 15 - iwm wifi - hello 2005 speeds...

A

ahhyes

Not much to say really except "DISAPPOINTING".... Decided to try out v15 on a Thinkpad T480s

From the iwm() man-page:
BUGS
Currently, iwm only supports 802.11a/b/g modes. It will not associate
to access points that are configured to operate only in 802.11n/ac
modes.

And yup, surely enough ifconfig shows that I am stuck in 2005 speed mode.
I am guessing nobody is interested in fixing this iwm "BUG" either..

The speeds are so awful I have to put youtube into < 1080p so it wont buffer all the time.
 
I do not know what wifi card is in T480S. i have T480 ( not S ). it had intel 8265 wifi card. i just swapped it for intel ax210 wifi and new iwx driver that is in 15 gives fantastic speed.
 
One thing I spotted also in the ifconfig output was OFDM/36. Using -powersave to turn off powersaving changed that to OFDM/54 but the speeds still max out at around 2.3MB/s - awful.
I guess that driver is just horrible :/

ahhhhhhh - thank you - this might be my way out of the problem - I see them on ebay for cheap.
 
If you decide to go with iwx driver and new card then make sure you blacklisted both iwm and if_iwlwifi drivers as the latter one has precedence over iwx. and install iwlwifi-ax210 firmware ( i cannot tell exact pkg name out of my head - pkg search can give it ).
 
I don't remember well, but iwm is used for old hardware and is not compatible with ac speed.
Indeed, that's easier to switch to an AX210.
You might check if your current wifi card has the correct driver and firmware, mine stayed on 14.3 version even after 15.0 upgrade - it did work but I was running strange behaviour before noticying the version mismatch.
 
My Thinkpad, T495, has an Intel card that doesn't get the newer speeds. It has an AC9x6x card. But I also have a Beelink SER5, with an AX200 Intel card, and that one has wireless speeds equal to the speed in Linux.
