hostapd-rtl's Issues
Compile with ACS
First of all, thank you for your project, it helps implementing WiFi APs on the BPI-R1 more easily.
I'd love to use Automatic Channel Selection with hostapd. This would require compilation with CONFIG_ACS=y. You can find some more information on ACS here.

i got this error when im restarting hostapd
how can i fix that

[Issue] SSID is visible but cannot join in
Synopsis:
When hostapd is configured with WPA-PSK enabled, Passphrase is set and then started, the AP SSID is visible from other devices (e.g.iPhone, macbook, PC). However, when joined the AP SSID, it kept challenging us to enter passphrase, despite we have entered correct passphrase.
When we disable WPA-PSK within /etc/hostapd/hostapd.conf file then re-started hostapd, our devices could join in the network without entering passphrase and all it's good. However, it's not desired since everyone could join in the network which could abuse our AP.
Replication steps:
- Ensure that DHCP server has been configured & started properly against the
wlan0interface. - Configure
hostapd.conffile as follow (enabled wpa-psk):
#ctrl_interface=/var/run/hostapd
#ctrl_interface_group=0

- Turn on the WiFi of any devices such as mobile phones, PCs, or laptops. Confirm that the AP SSID appears on the device's wireless networks screen.
- Join the AP SSID , enter correct passphrase and confirm that the screen returns
Incorrect Passphrasedespite we have entered correct passphrase. - Turn off
hostapd, edit the/etc/hostapd/hostapd.conffile and comment lines related to WPA-PSK feature to disable this. Re-startedhostapd. - Back to any devices (e.g. phone). re-join the AP SSID/ Confirm that the device could join the AP without entering passphrase.

This may be related to the driver in bananian as realtek's hostapd has the same exact routines to scan for 40MHz channels

Build on Ubuntu
Newer versions of Ubuntu only supply libnl-3-dev, could you update to support that?
As a workaround I grabbed the debs of libnl1 and libnl-dev for old versions of Ubuntu from its repos and successfully built hostapd-rtl. But that is a workaround and it would be better to work closer to out of the box.
client drops
Hi,
everything works fine, except that after a few hours all clients are dropped and can't reconnect till i reboot the bpi r1.
This problem is well known and there a many tips like
- firmware,
- switch off the powermanagement or
- timing issues.
Is there a working solution?
hostapdioctl[RTL_IOCTL_HOSTAPD]: Operation not supported
I get hostapdioctl[RTL_IOCTL_HOSTAPD]: Operation not supported
when running service hostapd start
am I doing something wrong? I am using the RB1
Driver initialization fails
I'm trying to use with DWA-131 in a beaglebone black:
Configuration file: /etc/hostapd/hostapd.conf
drv->ifindex=3
l2_packet_init: ioctl[SIOCGIFINDEX]: No such device
no br0 interface , let l2_sock_recv==l2_sock_xmit=0x0x51648
ioctl[SIOCSIWMODE]: Invalid argument
Could not set interface to mode(3)!
Could not set interface to master mode!
rtl871xdrv driver initialization failed.
rmdir[ctrl_interface]: No such file or directory
Do you have any idea?
A few general issues
Hi, so I'm using Arch on a Raspberry Pi and decided to build hostapd using the components in this repository, I noticed while running make I get the following messages:
CC ../src/ap/ctrl_iface_ap.c
CC ../src/ap/wpa_auth_ft.c
../src/drivers/driver_rtw.c: In function 'rtl871x_set_hidden_ssid_ops':

struct hostapd_data *hapd = drv->hapd;

^
CC ../src/drivers/driver_rtw.c
CC ../src/drivers/driver_nl80211.c
It doesn't seem to cause an issue but was hoping someone might have an idea. Additionally the 300-noscan patch doesn't seem to work, when I start hostapd I get the following:
Configuration file: hostapd.conf
drv->ifindex=4
l2_sock_recv==l2_sock_xmit=0x0xd10678

hostapd_free_hapd_data: Interface wlan0 wasn't started
ELOOP: remaining socket: sock=6 eloop_data=0xd10708 user_data=(nil) handler=0x5e52c
The above happens with the following config setting:
ht_capab=[HT40+][SHORT-GI-40]
Any help with this would be great, thanks.

RFE: auto-generate WPA PSK and enable service by default
Currently the init script is disabled by default for security reasons to protect from people using the sample WiFi password. This is not very intuitive.
This RFE is here to modify the postinstall script and generate a random WPA PSK and enable the init script by default.
We should also look into making the BSSID unique as well (append a suffix?)
openwrt 300-noscan.patch
hi jekader,
just info, could you update your repo to include new 300-noscan.patch (openwrt). according this url https://dev.openwrt.org/browser/trunk/package/network/services/hostapd/patches/300-noscan.patch it was updated 2 days ago.
check the 'status' doesn't work
update-rc.d -f hostapd defaults
root@superPi:~# update-rc.d -f hostapd defaults
update-rc.d: using dependency based boot sequencing
root@superPi:# /etc/init.d/hostapd status#
root@superPi:
no changes
root@superPi:# service hostapd status#
root@superPi:
both commands do not work.
Word of warning for Raspbian
Just a word of caution for modern Raspbians. Since Debian 8 (Jessie), Raspberry Pi/Raspbian changed its boot start mechanism from initscripts to systemd.
However, this hostapd-rtl code still relies on initscripts. This makes it incompatible with Raspberry Pi, leading to this error when installing the newly compiled package:
hostapd-rtl depends on initscripts (>= 2.88); however: Package initscripts is not installed.
Of course you can try to install the initscripts as advised, but this would mess with your boot start setup (initscripts depends on sysv-rc, file-rc or openrc - each of it is competing with the default systemd). Or you can arrange your own boot start scripts if desired.
I am not saying this is a fundamental flaw in this hostapd-rtl code. But I appreciate if you add some warning on the main page so the people are aware of the potential challenge.
