    RTL8188CE wireless card connects to router, but no internet access

    Recently installed Kali Linux 2018.1 on a secondary hard drive and I can't get the Internet to work using my wireless card. If I plug in an Ethernet cable, the internet works fine. My wireless card picks up my network, and I can connect to my router perfectly fine, but the Internet does not work. I've tried all the troubleshooting steps on the forums, tried several solutions on google and none of them worked. It seems to be a problem with DHCP, because I do not get assigned an IPv4 address. I know the card works because I have Windows 10 on my primary hard drive and it works fine when I use that. I've spent countless hours trying to fix it so any help would be greatly appreciated.

    Additional Info:
    -Wireless card: Realtek Semiconductor, Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
    -OS name: Kali GNU/Linux Rolling (Kali Linux 2018.1 most recent release, amd 64 bit)
    -GNOME Version 3.26.2

    I realize that this is an older post, however... What is the 'ifconfig' output? 'iwconfig' is only about wireless connections, not ip addresses.
    What i did to fix mine is removed network-manager and installed wicd:
    dhclient wlan0
    apt install wicd
    apt remove network-manager
    reboot
