RasPi Access Point Issue

Post by sal.fex »

I have the Wireless AP setup and it broadcasts a SSID, but when I try to connect to it I get the "Limited Access" message in Windows 7 and 8. The Pi does not give the systems an IP address, so I can not test it. It worked after the 'Testing' phase but not now.

That error message doesn't give much information about what might be wrong on the RasPi side.

For starters, what do you get from:

Code: Select all

sudo ifconfig -a
on the RasPi?

It looks like the wifi interface is configured properly with an IP address, so we can check that list of troubles off the list.

Let's make sure all the necessary services are running, and the OS is forwarding packets as it should:

Code: Select all

ps ax | grep hostapd
ps ax | grep dhcpd
sudo sysctl net.ipv4.ip_forward

Hi - sorry for the late reply, this fell off the bottom of the screen I normally check.

The `ps ax | grep dhcpd` command showed that your DHCP server isn't running. Double-check that section of the tutorial and see if those instructions get things working for you.
