Has anyone had any experience w/ USB WiFi error dmesg: ieee80211 phy0: Failed to initialize wep: -2

Hi, I’ve run into a new dmesg error with my USB WiFi adapter that I haven’t noticed before:

root@beaglebone:~# dmesg | tail

Does anyone know the cause of this kind of error? I’m running Angstrom and I get the same thing with my Realtek-8188/92 based adapters as well. Thanks!

Check your hub power supply

This maybe because your 5V external power is poor , made in china ?

Okay, so it’s likely to be power supply-related - good to know. Yes, probably made in china. I’ll have to get my hands on another hub and see if that fixes the problem. Thanks.
