Wireles card waiting for carrier

Hi. I'm having difficulties to make the wireless card to work. This is what I've done, in order:

command: lspci -k
result:
05:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8812AE 802.11ac PCIe Wireless Network Adapter (rev 01)
    Subsystem: ASUSTeK Computer Inc. RTL8812AE 802.11ac PCIe Wireless Network Adapter
    Kernel driver in use: rtl8821ae
    Kernel modules: rtl8821ae

command: ip a
result:
wlp5s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether b0:6e:bf:7c:59:a7 brd ff:ff:ff:ff:ff:ff

command: sudo ip link set wlp5s0 up
result: ok

command: ip a
result:
3: wlp5s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether b0:6e:bf:7c:59:a7 brd ff:ff:ff:ff:ff:ff

command: sudo dhcpcd wlp5s0
result:
wlp5s0: waiting for carrier
timed out
dhcpcd exited

Is there something I'm missing to activate the wireless card?

Re: Wireles card waiting for carrier

Could you try downgrading to linux 4.15.5 (don't forget linux-headers too) or try rtlwifi_new from lwfinger?

EDIT: I'm assuming you already have the wpa_supplicant hook configured to start with dhcpcd, otherwise follow the post above and ignore my advise.

Re: Wireles card waiting for carrier

You did say wireless, right?  What about that associating with your wireless access point.  You will not get a link to come up until you do so.  Read the wiki.  learn about wpa_supplicant. Figure out which service you want to use to control your wireless and configure it.  Many use NetworkManager.  Some use netctl.  I use systemd-networkd
