Good WiFi module that works with open80211s?

[astrand]

Hi. We are designing an IOT system from scratch and want to select a WiFi module that works good with 80211s. Our requirements are:

• A module, to reduce certification work
• Must work up to a temperature of at least 70 degrees celsius
• Tried and tested Linux kernel driver
• Should be able to participate in WiFi mesh and be connected to an "upstream" WiFi AP (gateway to Internet) at the same time
• Module should be available for purchase in the future (at least 5 years from now)

Any recommendations? We have looked at https://wireless.wiki.kernel.org/en/users/drivers which is useful. I have also found #80 so apparently it is not sufficient just to look for a "yes" in the "mesh" column for a certain driver. Any recommendations?

I would say that ath9k is the one that has fully tested.

For ath10k, you may look for following reference and try your luck.

Thanks for the information! It seems to me that ath9k mostly covers older modules, which are not available any longer. So, we will probably aim for ath10k instead. In particular, we are considering QCA9377, any experience with that one?

I suggest that you may post the questions over ath10k driver or community firmware forum, like OpenWRT. For you information, you still need to get the qualcomm-atheros firmware right with your chipset.
