I’m using a 6th generation Lenovo ThinkPad X1 Carbon, which for wifi uses the idualwifi7260 driver.
My wifi network is 4 ASUS ROG base stations using ASUS’ “AIMesh”, so they all share the same SSID.
This works fine for Mac, Windows, iPhone/Pad/etc and Android; they all just see the SSID and are moderately well optimized onto the nearest base station.
Haiku, on the other hand, lists all the base stations as different networks in the Network preferences, though all with the same name.
The wifi is quite slow on Haiku compared to the others, and has periods where it can’t maintain a connection for more than a few seconds.
I’m thinking these two things may be related, but I’m not sure how to look for more info in Haiku.
