802.11a is long ago obsolete and was not widely used.
Maybe you want 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6).
It is unlikely that you can use any better than 802.11n (Wi-Fi 4) on a Purism Librem laptop using PureOS without sacrificing your purity. In other words, you have to decide whether privacy/security are more important or less important than wireless performance.
Regardless of the WiFi device in your computer and support therein for that device … you will not do better than the WiFi standard supported by your access point (router). Hence if you have an 802.11n access point (router) then your computer will not get better wireless performance even if you install an 802.11ac or 802.11ax device in your computer. In other words, you may have to upgrade both in order to get better wireless performance.
For my money, if I want good performance then I go wired (gigabit ethernet).
Purism uses wifi cards that have open source drivers and are accredited with the Free Software Foundation. I don’t think there is a wifi card higher then /n that fits their requirements. You may be able to replace the wifi card in any of the Librem devices with a wifi /ac card. You’ll just need to make sure it fits, has the correct connector, and the required antenna. Then it’ll be easy to download the driver off the Debian archive.
If you find a few possible candidates I’m sure some people here might be able to help to find out if it might work.
Again, you’re right! My bad, I did mean to add the C (/ac not /a) it was late.
I should stick with the Librem 15 (L15) and ask the question better : Does the L15 come with RJ45 to a 802.11 /ac?
The “Technical specs” are not clear on that.
Same here - ergo my query.
As a side note FYI to anyone else searching, a friend sent me his stats he tested last night:
Downloads = 263.9
Uploads = 287.0
Downloads = 335.3
Uploads = 271.5
His modem/router settings are:
I hope to install PureOS today on a external drive as suggested by you earlier - - to get a better idea of how it works… and disable ‘sleep’ while trying PureOS. It will be like Christmas (aka ‘The Holidays’).
While you still have the old Atheros ath9k card in your Librem 15, install the proprietary firmware for the Intel WiFi card: wget http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20190114-2_all.deb sudo dpkg -i firmware-iwlwifi_20190114-2_all.deb
