error: Error for wireless request "Set Mode" (8B06) : invalid argument "roaming"
 
I noticed this error when restarting networking service. wireless works without a problem, so I was just curious:

1. what is causing the error
2. how can it be fixed
3. since the wireless is working, should I even worry about trying to fix it

the short answer is: no.

the long answer is, if you want a good excuse to get your hands dirty dealing with device drivers, go right ahead.

so i am using fedora core 6 w/ dlink usb wireless (dwl-g122) and was getting the same error. was i did was:

# depmod -A
# modprobe rt2570

and the error went away. however, i am still unable to get a valid IP from my access point as a dhcp client and am unable to get to the internet. static IP will work currently.

In my case I was not getting an IP either. It seems to be related to how the driver sets the Mode (Ad-Hoc, Managed, etc.) I changed mine from Auto to Managed (because that's the kind of network topology I have here) and shazaam no more error and I got my IP.


This didn't used to be a problem. So my guess is that perhaps a bug was introduced during one of the updates. But that's just a guess.

I got rid of the error by changing mode from Mode=Auto to Mode=Managed

THe "8B06" signifies that it is a iwconfig command or wireless driver error. It would be interesting to find out what was trying to set the card to mode "roaming" since that is not a valid name for a wifi driver mode. From "man iwconfig"

mode
Set the operating mode of the device, which depends on the net‐
work topology. The mode can be Ad-Hoc (network composed of only
one cell and without Access Point), Managed (node connects to a
network composed of many Access Points, with roaming), Master
(the node is the synchronisation master or acts as an Access
Point), Repeater (the node forwards packets between other wire‐
less nodes), Secondary (the node acts as a backup mas‐
ter/repeater), Monitor (the node is not associated with any cell
and passively monitor all packets on the frequency) or Auto.
