    Odd behavior tl-wn722n

    Got the TL-WN722N and looked to be pretty plug and play from what I read. I am running Kali on a Dell XPS 13 (not a USB / Live CD).

    I can see the device on wlan1
    lsusb
    Bus 003 Device 003: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

    Even airmon-g sees it
    airmon-ng
    PHY Interface Driver Chipset
    phy0 wlan0 iwlwifi Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak] (rev 34)
    phy2 wlan1 ath9k_htc Atheros Communications, Inc. AR9271 802.11n

    I can run nmap scans, I am getting an IP, I can ping local IPs but external gets a Network is unreachable
    ping 192.168.1.1
    PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

    64 bytes from 192.168.1.1: icmp_req=2 ttl=64 time=1.24 ms
    ^C

    root@notahacker:~# ping 8.8.8.8
    connect: Network is unreachable

    And when I try to browse the internet, nothing.

    I haven't loaded any drivers / backports as I was under the impression they were already loaded.

    I am running the latest version of Kali (just loaded it on this box in the last week). I did apt-get update / apt-get upgrade.

    Any help would be appreciated.

    I have tried swapping USB ports with no luck. Tried different networks, same results.

    Ok so I ran a route command and it looks like I am not getting a gateway for that adapter.

    route -n
    Kernel IP routing table
    Destination Gateway Genmask Flags Metric Ref Use Iface
    0.0.0.0 10.20.64.1 0.0.0.0 UG 0 0 0 wlan0
    10.20.64.0 0.0.0.0 255.255.254.0 U 0 0 0 wlan0
    10.20.66.0 0.0.0.0 255.255.254.0 U 0 0 0 wlan1

    But when I right click Connection Information - there is a default gateway.

    Do I need to manually set the gateway? How do I do it?

    Used

    route add default gw 10.20.66.1 wlan1

    to set it and was able to connect. Any thoughts on why it wouldn't automatically configure the gateway?
