Hi, Im trying to configure MadWifi as an AP on laptop A and connecting a client from laptop B. Although the station B associates correctly, Im unable to even do a simple ping to the AP Here is my configuration Laptop A: Lenovo Thinkpad Card: lshw -C network description: interface product: Atheros AR5001X+ Wireless Network Adapter vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:16:00.0 logical name: wifi0 version: 01 serial: 00:0b:6b:20:40:dd width: 32 bits clock: 33MHz capabilities: bus_master cap_list logical configuration: broadcast=yes driver=ath_pci latency=96 maxlatency=28 mingnt=10 multicast=yes resources: irq:16 memory:c4000000-c400ffff Here is the script I used to create an AP /********* #!/bin/sh sudo modprobe -r ath5k || true sudo modprobe -r ath9k || true sudo modprobe -r ath_pci || true sudo modprobe ath_pci autocreate=none sudo wlanconfig ath1 destroy || true sudo wlanconfig ath1 create wlandev wifi0 wlanmode ap # set up the AP sudo iwpriv ath1 mode 3 # 11g mode sudo iwconfig ath1 essid "Aditya" # essid sudo iwconfig ath1 key off # no wep sudo iwconfig ath1 enc off # no wep sudo iwpriv ath1 wpa 0 # no wpa sudo ifconfig ath1 up sleep 1 sudo ifconfig ath1 192.168.1.1 netmask 255.255.255.0 sudo sysctl -w dev.wifi0.diversity=0 sudo sysctl -w dev.wifi0.txantenna=1 sudo sysctl -w dev.wifi0.rxantenna= ************************/ Laptop B: Dell Inspiron Card: description: Wireless interface product: AR928X Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:0c:00.0 logical name: wifi0 version: 01 serial: 00:15:6d:84:35:8e width: 64 bits clock: 33MHz capabilities: bus_master cap_list logical ethernet physical wireless configuration: broadcast=yes driver=ath_pci latency=0 multicast=yes wireless=IEEE 802.11g resources: irq:19 memory:dfcf0000-dfcfffff Here is the script I used to create a STA /************* #!/bin/sh sudo modprobe -r ath5k || true sudo modprobe -r ath9k || true sudo modprobe -r ath_pci || true sudo modprobe ath_pci autocreate=none sudo wlanconfig ath1 destroy || true sudo wlanconfig ath1 create wlandev wifi0 wlanmode sta sudo iwpriv ath1 mode 3 # 11g sudo iwconfig ath1 essid "Aditya" sleep 1 sudo sysctl -w dev.wifi0.diversity=0 sudo sysctl -w dev.wifi0.txantenna=1 sudo sysctl -w dev.wifi0.rxantenna=1 ***********************/ In NetworkManager, I configured so that address is obtained through DHCP whenever the STA connects to AP "Aditya" Here is my dhcpd.conf file /*************** option domain-name-servers 192.168.1.1; default-lease-time 86400; max-lease-time 604800; authoritative; # basic setup by ADITYA BHAVE subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.10 192.168.1.20; option subnet-mask 255.255.255.0; option broadcast-address 192.168.1.255; option routers 192.168.1.1; } /*****************************/ Firstly, the STA is unable to obtain an address through DHCP. I then manually gave the STA an address of 192.168.1.10, with a netmask of 255.255.255.0 and a gateway of 192.168.1.1. I even ran the following command route add default gw 192.168.1.1 Inspite of both the above changes, a ping command fails ayb@AD-DELL:~$ ping -I ath1 192.168.1.1 PING 192.168.1.1 (192.168.1.1) from 192.168.1.2 ath1: 56(84) bytes of data.
