Seems RTL8192EE wireless card doesn't work with Linux 3.19

Hi all, I just fresh installed ArchLinux on my new Thinkpad T450s. The installation has been smooth enough. I can use wifi-menu on ArchISO image (which is based on kernel 3.18.6) to get my wifi connected. Everything works great. But when I reboot into the new hard disk installation, the WiFi connection always fails.

I have tried to connect manually via wpa_supplicant and dhcpcd. It didn't show any error information like driver issue or so. The problem I can see is the link is really slow: too slow to get authenticated by router. At a small chance I can connect to the WiFi but then failed to get dhcpcd work. And at a really really small chance I can get an IP from the router but the ping latency to gateway is about seconds, so I cannot visit any service via this network.

This issue happens to Linux 3.19. I have tested on 3.19.2 in core and 3.19.3 in testing.

Is there any of you have the same issue, and is there a solution for this currently?

EDIT: typo

Thanks for your reply.

I have installed Linux-LTS but it cannot detect the wireless card.

Installed aur dkms driver then finally connected!

For those using kernel 4.0, the problem is partially gone. The wireless connection doesn't randomly drops and you can always connect correctly but you can get really slow speed, and sometimes all packages are lost.

Installing this new version of the driver solves the problem:

sudo git clone http://github.com/lwfinger/rtlwifi_new.git
cd ./rtlwifi_new
sudo make
sudo make install
sudo modprobe -v rtl8192ee

Yes, rtlwifi_new works for me. I do hope this can be merged into mainline some day.
