rtl8821ae wifi working like crap

I'll just notice that this problem isn't that new and it's already third monthly build on which my laptop wireless isn't working - and not only on Arch.
I'm operating with installation medium, so please keep in mind that the set of possible actions is kinda limited for me.
My actions after root autologin:

# rfkill unblock wifi
# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether c8:5b:76:7e:f5:70 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 78:45:61:f4:d0:a5 brd ff:ff:ff:ff:ff:ff
# ip link set wlp2s0 up
# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether c8:5b:76:7e:f5:70 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 78:45:61:f4:d0:a5 brd ff:ff:ff:ff:ff:ff
# wpa_supplicant -iwlp2s0 -Dnl80211 -c<(wpa_passphrase ssid password)

That's where the magic begins.
After that line, anything is possible: hanging after "succesfully initialized wpa_supplicant", hanging after "SME: trying to authenticate with blah-blah-whatever", not hanging and even connecting but disconnecting finally after a minute...
On June or July build, I've got something like "Init MAC failed"...

Can you guys propose me something that works? I'm losing hope.
Yeah, kernel module rtl8821ae and the same adapter (Lenovo laptop card, combined with bluetooth). No problems with firmware loading, judging by dmesg output.

Re: rtl8821ae wifi working like crap

I've been struggling with this issue for the past ~6 months as well. I have a Lenovo y520 with the rtl8821ae and the integrated bluetooth. In the end I gave up and bought a USB wifi dongle (the CSL-300 Mbit/s with removable antenna) and am quite happy with it now.
