I'm having a slew of issues with iwm() WiFi on my Dell Inspiron 5567 being slow and randomly disconnecting when the access point is far or the signal is not very strong.
In particular, I'm experiencing random connection losses when connected to public WiFis with multiple access points (I've configured
I noticed that dmesg is full of the following errors, which I think are associated with the disconnection episodes:
The adapter is a Wireless AC 3165 (dual band, both 2.4 and 5GHz); I'm running on FreeBSD 12.0-p3 + binary packages.
In particular, I'm experiencing random connection losses when connected to public WiFis with multiple access points (I've configured
wpa_supplicant for both encrypted and unencrypted networks); the network is also generally much slower under FreeBSD than under Linux/Windows when using the same adapter, which I'm currently mitigating using USB tethering with an Android phone connected to the same networks, which results in a vastly more stable connection.I noticed that dmesg is full of the following errors, which I think are associated with the disconnection episodes:
