[SOLVED] build an accesspoint

carlitoco · 12-31-2010, 11:30 AM

I want to build up an wifi accesspoint with my laptop.

1.

I've installed the firewall form Alien Bobs efg http://connie.slackware.com/~alien/efg.
1.1 choose the "gateway" option
wlan0
ip 10.1.1.1
netmask 255.255.255.0
and so on...

Manual set up

Code:

ifconfig wlan0 down
iwconfig wlan0 mode managed/ad-hoc
ifconfig wlan0 up
iwconfig wlan0 essid test
iwconfig wlan0 channel 1
iwconfig wlan0 key off

okay i think thats right!?

now I have here a script like this:

Code:

#!/bin/sh
IFACE="wlan0"
IADDR="10.1.1.1"
NMASK="255.255.255.0"
BCAST=`/bin/ipmask $NMASK $IADDR | sed 's/ .*//'`
/sbin/ifconfig $IFACE $IADDR broadcast $BCAST netmask $NMASK
/sbin/ifconfig $IFACE $IADDR up

Is it neccessary to use it like this ?

#ifconfig
to check

Code:

wlan0     Link encap:Ethernet  HWaddr 00:19:e0:8b:ed:35  
          inet addr:10.1.1.1  Bcast:10.1.1.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:990 errors:0 dropped:0 overruns:0 frame:0
          TX packets:473 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:324508 (316.9 KiB)  TX bytes:106391 (103.8 KiB)

#iwconfig

Code:

wlan0     IEEE 802.11bg  ESSID:"test"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

I tryed to set up the "ad-hoc" mode and the "managed" mode, but doesn't get access.

please help me !

And a happy new year !

As the output of iwconfig shows, the card is in "Managed" mode, which is the standard operating mode (in other words, the card is trying to connect to an AP with the SSID "test"). You need to put the card into either Ad-Hoc, or ideally, Master mode.

Try just doing "iwconfig wlan0 mode master", and then if that gives an error (not all chipsets/drivers support Master) then do "iwconfig wlan0 mode ad-hoc".

master mode doesn't work because I don't have madwifi, tryed to compile last days but it (Slackbuilds.org) doesn't work.

Funy! My Smartphone already get the static ip connection to my "test" network, my other slackware wicd-controlled PC didn't connect.

How to connect manualy to wireless lan?

Code:

ifconfig wlan0 down
iwconfig wlan0 mode managed
ifconfig wlan0 up
iwconfig wlan0 essid test
iwconfig wlan0 channel 1
iwconfig wlan0 key off

and than ?

Code:

# dhcpcd wlan0

can't be right!?

thx!
