Hey, I'm new here, but from what i learned is that when you run kismet or a few other programs, it sets you into Monitor Mode. So you have to set your card to Mode Managed in order to surf the web. So each time after you use kismet or any other Monitor Mode enabling program go open up a bash prompt, and type:
iwconfig <interface> mode managed
So in example you would type
iwconfig eth1 mode managed
My card is eth1 so just use your correct interface here. after that, just type:
ifconfig ath0 up
iwconfig ath0 essid linksys
dhcpcd
and your good to go
P.S.
I'm guilty of using wifimanager to connect me to a AP, so cause of reading this I'm going to try to stop this. Also, you can type iwconfig to see the mode of your card. Cya
