 |
|
I finally got the 4.3.22-beta6 8812au driver installed and can put my card into monitor mode. I can verify that it works, as it is getting packets from multiple networks. In fact, that seems to work just fine.
Unfortunately, it looks like airodump-ng can't figure out how to change the channels to do a scan. If I do 'iwconfig wls35u1 channel 1' for example, airodump-ng will get stuff on channel 1 and properly identify it. However, airodump-ng is trying to channel hop and it's as if the command to change the channel never gets to the card. There are no error messages in the kernel log regarding this. I can manually change the channel while airodump-ng is running with either iw or iwconfig, but it doesn't appear as if airodump-ng can do it itself.
Any ideas? |

Wormer ...
please show what you're doing ... from the above it looks like you're using the 'wls35u1' interface and not the monitor interface. Also, what version of aircrack-ng, and what 'airmon-{ng,zc}' are you using to create the monitor?

# iwconfig
| Code: |
wls35u1 unassociated Nickname:"<WIFI@REALTEK>"
Mode:Managed Frequency=2.412 GHz Access Point: Not-Associated
Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level: 0
{packet stats, all 0}
|
If I then run 'airmon-ng start wls35u1' I get:
| Code: |
PHY Interface Driver Chipset
phy1 wls35u1 ?????? Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter
cat: /sys/class/ieeee80211/phy1/device/net/wls35u1mon/type: No such file or direwctory
Newly created monitor mode interface wls35u1mon is *NOT* in monitor mode.
Removing non-monitor wls35u1mon interface...
|
If I run 'airmon-ng check kill' it kills dhcpcd which is running on a virtual ethernet interface, but doesn't improve matters.
Now, if I do:
| Code: |
# iw wls35u1 set type monitor
#
|
| Code: |
# iwconfig
wls35u1 unassociated Nickname:"<WIFI@REALTEK>"
Mode:Monitor Frequency=2.412 GHz Access Point: Not-Associated
Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level: 0
{packet stats, all 0}
|
In this configuration, I can run 'airodump-ng wls35u1 --band a' and it will start sniffing networks, but only on channel 1. The program says it's hopping in the upper left corner, but all data received is for channel 1. I can go in behind it in a different terminal and manually change the channel to anything else and it will start picking up on that channel.
The problem appears to be that airodump-ng doesn't know how to change the channels. |

Wormer ... that would seem to be a typo in airmon-ng ... it should be 'ieee80211' not 'ieeee80211'.
| Code: | | # sed -i -- 's/ieeee80211/ieee80211/g' /usr/sbin/airmon-ng' |
Also, its not detecting 'Driver', which may, or may not, cause the setup to fail.

The whole point of airmon-ng is to create the monitor device, so don't expect 'iw' to succeed where airmon-ng failed.

With '--band a' it may be your regdomain ... did you also get the same result with 'g'?
Again, what version of aircrack-ng?

Try
ifconfig wls35u1 down
first, then start sniffing
