Hello,

I am having problems with a mad wifi access point, I am not running hostap at this time. I can connect to the ap from my clients but I can't surf, I am bringing up ath0 manually also entering my essid via iwconfig for ath0 manually.

Any help would be appreciated.

Thank you,

Hello and welcome.
Have you tried running dhcp on ath0?
maybe dhclient or dhcpcd??

No I have not Mike, all the tutorials I have looked at did not mention dhcp.. I will look into that.

Thanks,

Keith

MikeTbob

If you are using a GUI like NetworkManager, it should do it for you.

Hello,

Mike I am working on this remotely I am not home to test yet. This is what I get when I issue dhcpcd

tom:/etc/network# dhcpcd ath0
err, ath0: timed out
warn, ath0: using IPV4LL address 169.254.154.17
dhcpcd.sh: interface ath0 has been configured with new IP=169.254.154.17

Do I need to configure a dhcp server also? Dhcpcd assigned a different ip and netmask from what I am using on my network. I have a centos box running as a nat going to a cisco 2600 switch. This is a debian box I am trying to configure as an ap on the network to give you a bit of a back ground.

Thanks again,

Keith

Hello,

I have set up dhcp3-server, since both eth0 and ath0 are bridged do I need to assign the dhcp server to a specific interface? This is my dhcpd.conf

tom:/etc/dhcp3# cat dhcpd.conf
ddns-update-style none;

option domain-name-servers 145.253.2.75, 193.174.32.18;

default-lease-time 86400;
max-lease-time 604800;

authoritative;

subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.200 192.168.2.229;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.2.255;
option routers 192.168.2.1;
}

Thanks again,

Keith

To tell you the truth, I don't know anything about bridging interfaces....mabybe someone else can chip in here.

Thanks Mike you made my day for pointing me in the right direction. I never ran DHCP all my ip's were set static in the interfaces. I setup a dhcp server and resolved some rules with iptables, I have been up and working secure with hostap since. Sorry I did not reply faster, been tied up with work... I just wanted to say thank you!!

Keith

MikeTbob

Glad you got it working and I hope you enjoy using Linux.
