Airbase-ng 5Ghz band?

[Nick_the_Greek]

Since I don't own a dual band wireless NIC does anybody knows if airbase-ng supports 5Ghz band channels and which channels are supported (if any)?

I know that you can setup a 5Ghz SoftAP with hostapd, if a card supports 5Ghz AP mode and if I'm not mistaken you can use channels 36 40 44 48 52 56 60 64 depending to our CRDA country that you use and NOT channels 100 104 108 112 116 120 124 128 132 136 140 149 153 157 161 165

Maybe I'm blind but I could not found any informations about airbase-ng in 5Ghz band, so if anyone knows something about this please let me know.

You might post this in the airbase-ng forums. I am sure MisterX will answer you. We tried to get airbase-ng to support WPA encryption and MX answered us explaining the difficulties so I assume he has something to do with airbase-ng as he is the moderator of aircrrack-ng

Yeah I thing you're right. I just did it. I "know" MisterX. We have a discussion 4-5 years back about airbase-ng and WEP encryption.

Thanx mmusket33!

OK, since i've got no feedback I will ask a volunteer to check if airbase-ng supports 5Ghz channels. So, it looks like airbase-ng doesn't care about the channels that are supported by the wireless NIC. It accepts any channels from 1 to 255.

airbase-ng -c 1000 -e any mon0
Invalid channel value <1000>. It must be between 1 and 255.

and if i set channel 36 (my wireless NIC doesn't support 802.11a channels)

airbase-ng -c 36 -e teddy mon0
22:21:28  Created tap interface at0
22:21:28  Trying to set MTU on at0 to 1500
22:21:28  Access Point with BSSID xx:xx:xx:xx:xx:xx started.

So, if your card supports 5Ghz channels please run:

# Assuming that you wireless interface name is wlan0 and you got NO other running monitor mode interfaces (monX)
service network-manager stop
airmon-ng start wlan0
# 5Ghz channels are 36 40 44 48 52 56 60 64 (for broadcasting) Please try some of them.
airbase-ng -c 36 -e teddy mon0

If you got enough patience please try also channels : 100 104 108 112 116 120 124 128 132 136 140 149 153 157 161 165
and check if the SoftAP that we have created with airbase-ng is viewable by another 5Ghz capable PC.

I really appreciate any help you can provide.

OK. "Mystery" solved.

I'm transferring the reply from the author of aircrack suite (misterx) for a future reference:
http://forum.aircrack-ng.org/index.p...7.html#msg2057

The following command will tell you where you can transmit: iw phy phy0 info (replace phy0 by your card's phy)

And this one will let you change the regulatory domain (needed in Kali since it defaults to world domain and it is more restrive than the US and I guess a lot of other countries): iw reg set US (or whatever country you're in).

There is no information about airbase-ng and 5GHz because it's just a different channel number. The tools in the suite don't care much about the frequencies. By that I mean that it all depends on the capabilities of your card. Your card might support 2.4GHz, 5GHz, 900MHz, 3.6Ghz. It does not matter. Look at the capabilities of your card and that all that counts (and obviously the fact that it needs to have a driver that supports monitor mode).
