iwlist scan shows non-existent hotspot

<< < (3/5) > >>

GNUser:
I found that removing then reloading my wifi interface's kernel module clears the cache:


--- Code: ---$ sudo modprobe -r ath9k
$ sudo modprobe ath9k
$ sudo ifconfig wlan0 up
$ sudo iwlist wlan0 scanning last
wlan0     No scan results # nothing in cache, nice!
$ sudo iwlist wlan0 scanning
-> no cached hotspots in scan result :)
--- End code ---

It works, but it's a kludge. Does the above suggest where the cache might be hiding?

jazzbiker:
Hi, GNUser!

It may be internal kernel buffer (

GNUser:
Thanks, jazzbiker. Seems we're getting warmer.

Hopefully the kernel does not have one giant buffer for everything. There must be a sub-buffer with cached wifi scan results somewhere. I'll try grepping though /proc, but I suspect the buffer is binary and I'll get no hits.

jazzbiker:
Wow, You monster! You want to destroy our beloved TinyCore! Stop immediately!!!

GNUser:
Haha. TCL made me fearless. If the computer blows up in my face, a reboot magically fixes everything ;D
