From what I can tell, the issues is with firmware not being loaded. What am I doing wrong? How to fix it?

Re: [SOLVED] TL-WN725N: firmware doesn't get loaded

First, I already have rtl8188eufw.bin:

$ pacman -Qo /usr/lib/firmware/rtlwifi/rtl8188eufw.bin
/usr/lib/firmware/rtlwifi/rtl8188eufw.bin is owned by linux-firmware 20150904.6ebf5d5-1

Do I still need to install dkms-8188eu?

Second, I can see only 8188eu-dkms in aur. And the thing is I've got no wired connection for now, so I'm booting ubuntu, chroot to arch linux, `pacaur -S 8188eu-dkms`, but it says:

Your kernel headers for kernel 3.13.0-32-generic cannot be found at
/usr/lib/modules/3.13.0-32-generic/build or /usr/lib/modules/3.13.0-32-generic/source.
error: command failed to execute correctly

Which is ubuntu's kernel version. Is there anything I can do about it?

Re: [SOLVED] TL-WN725N: firmware doesn't get loaded

firmware is firmware, module is module; dkms is for building module.

Apparently ubuntu is using the same staging driver instead of what provided by the dkms package.

Btw have you tried loading the cfg80211 module manually? Is it loaded automatically? Coz I don't see r8188eu depends on it. Seems like a bug?

Re: [SOLVED] TL-WN725N: firmware doesn't get loaded

First, thanks for the link, jasonwryan, it now works. The trick was to begin installing it manually (without pacaur), run makepkg for it to downloaded all the needed files. And then retry after booting the installed OS (arch linux, not ubuntu running from usb). The thing that I don't really get is that 8188eu-dkms depends on dkms, and the later was successfully installed as well without internet connection. My conjecture would be that it was taken from cache.

And the other two strange things is that with dkms module it calls itself enp0s29f7u2, not wlp0s29f7u2. And here what I see in dmesg after plugging it in:

[   47.963364] usb 2-2: new high-speed USB device number 2 using ehci-pci
[   48.146787] RTL871X: module init start
[   48.146792] RTL871X: rtl8188eu v4.3.0.8_13968.20150417
[   48.148828] bFWReady == _FALSE call reset 8051...
[   48.168739] RTL871X: rtw_ndev_init(wlan0)
[   48.169096] usbcore: registered new interface driver rtl8188eu
[   48.169099] RTL871X: module init ret=0
[   48.176566] rtl8188eu 2-2:1.0 enp0s29f7u2: renamed from wlan0

Supposedly, it calls itself RTL871X. But still it works.

By the way, I couldn't make it work without reboot. And unloading r8188eu didn't help. (The dkms one is called 8188eu.) So I guess, one should either install dkms package if the adapter wasn't plugged in yet. Or install and reboot.

Then I did:

$ ip link set enp0s29f7u2 up

firmware is firmware, module is module; dkms is for building module.

For some reason I thought the fact that module is also there is obvious.

$ find /lib/firmware/ -name '*8188eu*' -exec pacman -Qo {} \;
/usr/lib/firmware/rtlwifi/rtl8188eufw.bin is owned by linux-firmware 20150904.6ebf5d5-1
$ find /lib/modules/`uname -r` -name '*8188eu*' -exec pacman -Qo {} \;
/usr/lib/modules/4.2.5-1-ARCH/build/drivers/staging/rtl8188eu/ is owned by linux-headers 4.2.5-1
/usr/lib/modules/4.2.5-1-ARCH/build/include/config/r8188eu.h is owned by linux-headers 4.2.5-1
/usr/lib/modules/4.2.5-1-ARCH/kernel/drivers/staging/rtl8188eu/ is owned by linux 4.2.5-1
/usr/lib/modules/4.2.5-1-ARCH/kernel/drivers/staging/rtl8188eu/r8188eu.ko.gz is owned by linux 4.2.5-1

Apparently ubuntu is using the same staging driver instead of what provided by the dkms package.

the one that comes with the kernel?

Btw have you tried loading the cfg80211 module manually? Is it loaded automatically? Coz I don't see r8188eu depends on it. Seems like a bug?

cfg80211 module is not loaded with or without dkms package being installed. That is, it doesn't need to be loaded for it to work from what I can tell. At least under arch linux. Loading it without installing 8188eu-dkms didn't help.

Thanks for your replies, guys.

P.S. The driver can also be found here. But that probably is the one that comes with dkms package.
