Update berate_ap

[realalexandergeorgiev]

fix for "ERROR: Your adapter can not transmit to channel 1, frequency band 2.4GHz." - see #12

iw list now seems to add ".0" to the frequency, which causes parsing to fail. may be similar for 5ghz, not tested due to lack of hardware.

10:44 root@kali /alex $ iw list | egrep " MHz "

Im looking at the linux-router project (The successor to create_ap), and seeing how they addressed this. What are your thoughts on https://github.com/garywill/linux-router/blob/master/lnxrouter#L624-L641.

As an additional note, your regex does not escape the .. This solution also has the effect of killing previous iw outputs so it will kill backwards compatibility.

Yes,true. Feel free to add the [], but I strongly believe whoever uses kali has it up2date anyway ;)

I faced the same issue for both 2.4 GHz and 5 GHz. Fixed it by simply adapting the grep to match the frequency in float format:

    if [[ $USE_IWCONFIG -eq 0 ]]; then
        if [[ $FREQ_BAND == 2.4 ]]; then
            CHANNEL_INFO=$(get_adapter_info ${IFACE} | grep " 24[0-9][0-9]\.0 MHz \[${CHANNEL_NUM}\]")
        else
            CHANNEL_INFO=$(get_adapter_info ${IFACE} | grep " \(49[0-9][0-9]\|5[0-9]\{3\}\)\.0 MHz \[${CHANNEL_NUM}\]")
        fi

Thank you, I took the code from Linux-router and applied it.
