@Dalto1

Which WiFi device are you using on the Pine, onboard addon or USB?

[Dalto1]

Onboard addon

[Fourdee]

Unable to replicate on fresh install of Pine A64 and hotspot installation using addon board. Appears to be working fine. Internet worked a treat through hotspot.

@Dalto1
Possibly limited to your system/installation, we'll need to do some debugging.
Apologies for the delay in response. Could you please send us a bug report as we need some system information:
http://dietpi.com/phpbb/viewtopic.php?f=8&t=499#p2184

Could you also please paste results of the following commands:

systemctl status hostapd.service -l
cat /etc/hostapd/hostapd.conf
iwconfig wlan0
iwconfig wlan1
lsmod | grep brcmfmac
cat /etc/dhcp/dhcpd.conf

Note to self:

• Check wifi index, Pine image has a habit of providing wlan0 or wlan1

You will also need to add an iptables masquerade rule and enable forwarding.

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

[Fourdee]

@aliosa27
Yep, this should be applied during install:
https://github.com/Fourdee/DietPi/blob/master/dietpi/dietpi-software#L7927-L7937

@Dalto1
Could you try a reinstall of the HotSpot, might resolve it:

dietpi-software uninstall 60
reboot
dietpi-software install 60
reboot

[Dalto1]

Its not working. I strangly saw that ipv6 was activated so i uninstalled it from dietpi-config. But i cant get it to work, even with install/reinstall/uninstall and aplying the commands that @aliosa27 sent.

[Dalto1]

btw, my settings are the same after uninstall/install, so i assume that my settings are saved somewere, is there any command to purge them?

This is what gets uninstalled, covers everything excluding wifi_hotspot_ssid=, which is pulled from dietpi.txt:
https://github.com/Fourdee/DietPi/blob/master/dietpi/dietpi-software#L9422-L9463

cat /etc/dhcp/dhcpd.conf

Can we confirm that the DNS server entry below exists cat /etc/dhcp/dhcpd.conf (was missing from your paste)

option domain-name-servers 8.8.8.8, 8.8.4.4;

Also, which devices have you tested with the HotSpot and no connection to internet (eg: android, win PC etc)?

To help us determine if the issue is related to current installation:
If you have a spare SD card, please try a fresh installation of DietPi, install HotSpot and see if problems persist.

Cant connect with android, ill test on pc when i got time and try a new sd too.

[Dalto1]

maybe my iptables are mess up?

[Fourdee]

@Dalto1

maybe my iptables are mess up?

Possibly, although we flush IP tables during uninstall of HotSpot, so it should be same as my test install.

Either way, lets check your IPtables on the current installation, and i'll compare against a test install:

iptables-save > /root/iptables
cat /root/iptables

[Dalto1]

Ill reinstall dietpi on it when i got more time, but thanks anyways !
