Hi Florian, What I meant to say is that I enabled the 5 GHz radio in my router and connected to its ESSID (distinct from the 2.4 GHz radio.) With wpa_supplicant, I don't use the -D option so can't comment on it. The iw dev|list|scan|info commands are very informative.

I'm not familiar with that particular chipset. However, based on the above, that would suggest your network card presents the 5 GHz radio on wlan0, and the 2.4 GHz radio on wlan1.

What they did was to switch around the frequencies used by wlan0, and wlan1. This was done by defining the band to use in the radio0 and radio1 sections of /etc/config/wifi. How that actually does what it does behind the scenes of UCI abstraction I wasn't able to figure out. The result of this was that I needed to rmmod the modules used by one card, run wifi down, uncomment the band lines in each radio section, and run wifi up with no networks enabled in order to scan for networks on a particular band, and then I needed to run wifi down, reverse changes in /etc/config/wifi, modprobe modules, and run wifi up to connect to a network. I wondered why they did this, until I discovered that using I believe the 5 GHz radio in the 5 GHz band caused both wifi radios to become unresponsive. I needed to either reboot the router, or rmmod all wifi modules, and modprobe them again to regain wifi functionality.

Hallo Joel, may I ask, how you managed to set your Wifi-Adapter to 5GHz? After moving to a new place where I have to go wireless with my Desktop (WTH?!), yesterday I ran into a similar issue, with wpa_supplicant (both, with '-D wext' and with '-D nl80211') as well as with a pure '/etc/network/interfaces' config) [1]: With both available USB-WiFi-Dongles (rtl8192cu and rt2800usb), I can see the devices $ iw dev $ iw list resp. $ iw phy0 info as well as the available networks $ iw wlan0 scan but dhclient times out, when querying the "Fritzbox": No DHCPOFFERS received. No working leases in persistent database - sleeping. Installing NetworkManager via Android-AP and '/etc/network/interfaces', as an "emergency workaround", solved the issue for now. Interestingly, $ iw dev tells me, that I am not connected with 5GHz, as I first had assumed, but on channel 11 (2462 MHz), width: 20 MHz, center1: 2462 MHz Now I'd be curious to see, if with 5Ghz I can go back to my plain old config - and how it compares to 2.4GHz in a wooden House. Thank you and libre Grüße, Florian BTW: I was very surprised to find chimaera's wicd depending on networkmanager!

The problem seemed to be with my wifi configuration. I'd been using the 2.4GHz radio. Perhaps the settings, based on Apple recommendations, weren't the best. In any case, by enabling the 5GHz radio with AC mode, WPA2-PSK and 80MHz signal width my BCM43228 associated with the router and received an IP address.
