ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make
sure RFMON is enabled: run 'airmon-ng start eth1 <#>'
Sysfs injection support was not found either.
laptop:~$ sudo airmon-ng start eth1

Found 5 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

so i have been trying to figure this out for the last couple of days and i dunno what i am doing wrong. i have aircrack installed but when i run /sbin/iwconfig it tells me i have no wireless device, however i am connected to a weak wireless signal right now as i am typing this(which is also why i have not bothered to search for an answer in the forums because the signal is so damn slow...sorry)
