Can not build a Soft-AP using hostapd

[oldsharp]

Try to build a Soft-AP with rtl8188eu, but it failed.
My steps:

• git clone https://github.com/lwfinger/rtl8188eu.git
• cd rtl8188eu && make && make install
• insmod 8188eu.ko
• ifconfig wlan0 up
• hostapd hostapd.conf

An AP is built now and I can find the AP with my mobile device.
But I can not access this AP after I typed right password. The hostapd reported:

+rtl871x_get_sta_wpaie, 18:e7:f4:93:f2:b3 is sta's address
wlan0: STA 18:e7:f4:93:f2:b3 IEEE 802.11: associated
rtl871x_set_key_ops
rtl871x_set_key_ops
+rtl871x_send_eapol
+rtl871x_send_eapol
+rtl871x_send_eapol
+rtl871x_send_eapol
+rtl871x_sta_deauth_ops, 18:e7:f4:93:f2:b3 is deauth, reason=2
rtl871x_set_key_ops
wlan0: STA 18:e7:f4:93:f2:b3 IEEE 802.11: deauthenticated due to local deauth request
+rtl871x_sta_remove_ops, 18:e7:f4:93:f2:b3 is sta address removed
wlan0: STA 18:e7:f4:93:f2:b3 IEEE 802.11: disassociated

Looks like my password is wrong, but that's not the case.
I set driver=rtl871xdrv in hostapd.conf (set driver=nl80211 hostapd can not start).
My environment is Ubuntu 12.04 with i386 PC, the commit version I used to build the module is 993b021.

I will try to duplicate your result.

[oldsharp]

In fact I have no idea about how to build a Soft-AP with driver of this version.
I followed some instructions related to this source to built a Soft-AP and it works. But no luck with driver of this version.
Have you ever succeed to built a Soft-AP and how?

Hi, I've had similar problem and found out that after the commit 954eab3 the hostapd stopped to work..
when using revision before, everything works like a charm...

[lwfinger]

I assume that you did a 'git checkout 6d1127b' to get that version. If so, please do the following:

git checkout master
git revert 954eab3

Does hostapd work now? Those commands will allow us to test everything after the bad commit. If that functions, I will break 954eab3 into a set of smaller changes so that we can isolate the problem.

[lwfinger]

I found a problem with commit 954eab3 and pushed a fix. If you did the revert of 954eab3, then do the following:

git reset --hard HEAD^

Then do a 'git pull' and tell me if it works.

[artaban]

yes, it works now.. thank you!

[oldsharp]

Works good for me. Thanks!

[lwfinger]

Thanks for the feedback.

What driver are you using in the conf ?
I tried rtl871x but it's not working for me Line 39: invalid/unknown driver 'rtl871x' .

[oldsharp]

driver=rtl871xdrv and it works for me.
