Wireless network?

[fvdw]

short how to to setup wireless connection form my notes. I can be missing some items but basically this it is how to do it.

make a configuration file and put it in /etc/wpa_supplicant
example conf file (wpa_supplicant.conf)
Replace your-sid and your-passkey by the the actual values set in your wlan (keep the quotes as shown)
Note that these names are case sensitive !

Code: Select all

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=root
update_config=1

network={
ssid="your-ssid"
scan_ssid=1
psk="your-passkey"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=TKIP
}

check if your driver is loaded (wlan0 must be available)

Code: Select all

iwconfig

If it is not found then the driver is not or not correctly loaded and it won't work

bring up interface

Code: Select all

ifconfig wlan0 up

connect to wifi access point

Code: Select all

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B

get an ip address from dhcp server

Code: Select all

udhcpc -b -i wlan0 -q -s /etc/simple.script

In principle now the wlan should be up.

To keep connection when your LAN cable is disconnected you need to adapt the route table
add route for wlan0 (replace xxx.yyy.xxx.yyy by actual ip of your gateway)

Code: Select all

route add default gw xxx.yyy.xxx.yyy dev wlan0

now you should be able to bring down the wired connection

Code: Select all

ifconfig eth0 down

But if you do that then the connection you are using will be lost, and you should use the wireless ip to connect.

You can go here for more information to set it up using command files to switch between fixed and wlan connection (after you set up the connection with wpa_supplicant and obtaining ip)

some helpful commands
to check status

Code: Select all

wpa_cli status


To see which networks your dongle sees and get more info

Code: Select all

iwlist wlan0 scanning

[steean]

Hey, thanks for the guide. I've been busy, but I WILL try this out as soon as I get the chance. I take it that the wired network connection is default on reboot..?

[steean]

Hm. I tried out the first few steps, but can't get any further.. When I execute

Code: Select all

iwconfig

I get

Code: Select all

-sh: iwconfig: not found

also, when I execute

Code: Select all

ifconfig wlan0 up

I notice how it says

Code: Select all

Link encap:Ethernet

and I wonder if that's correct..

[fvdw]

oops, my fault 15-1 is missing some files for wireless tools

attached a patch, you can upload it using the upload patch menu in the webinterface
put the zip file in the share with name "fvdw"
use as control code "unzip" (without the quotes) in the web interface upload file window

[steean]

Ok, so I installed your patch and I was able to get my NAS connected to the router and acquire an IP-address. I was not able to reach any services via the wireless IP (ping, ssh, web-gui or shares). I didn't bring the Ethernet down, so maybe that's it...? Does fvdw only publish services through one interface at a time?

I did all the steps again on my nwsp2 and ended just like steean.

You know that it worked for me with fvdw 14, but 15.1 seems to have problems. IP is assigned in the router but i cannot access the webinterface. There is a error message when calling udev with the simple script:

root@fvdwsl-base:/ # /etc/simple.script: line 1: can't open !DOCTYPE: no such file
> /etc/simple.script: line 1: html: not found
> /etc/simple.script: line 2: syntax error: unexpected newline
> Sending discover...
> Sending select for 192.168.178.35...
> Lease of 192.168.178.35 obtained, lease time 864000
> /etc/simple.script: line 1: can't open !DOCTYPE: no such file
-sh: /etc/simple.script:: not found
root@fvdwsl-base:/ # /etc/simple.script: line 1: html: not found
-sh: /etc/simple.script:: not found

I do not remember I had this message with fvdw 14. Has something changed there?

[fvdw]

yes there are changes made to udev in version 15-1.

we will need to look at this

[fvdw]

:scratch I can not reproduce your error

seems to work all normal

Code: Select all

root@nwsp2-5:/ # udhcpc -b -i wlan0 -q -s /etc/simple.script
udhcpc (v1.21.0) started
Sending discover...
Sending select for 192.168.1.33...
Lease of 192.168.1.33 obtained, lease time 86400
root@nwsp2-5:/ #

this nwsp2 is running 15-1 (with wireless tools patch)

but indeed the webinterface doesn't respond on the wlan ip

---edit
temporary you can solve it by giving this command (replace the ip by the actual one assigned by dhcp server)

Code: Select all

/sbin/ifconfig wlan0 192.168.1.33 netmask 255.255.255.0

now you can connect to webinterface using this ip

[matzi]

Yep,
the workaround helps. After this IP assignement ifconfig shows the correct IP4 adress. Witout that only an IP6 us assigned from udhcpc. Why that? Could there be a mistake in simple.script

I attach the verbose output of udhcpc here:

root@fvdwsl-base:/ # /sbin/udhcpc -b -v -i wlan0 -q -s /etc/simple.script

Please note that I did not have simple.script in my installation after upgrade to 15.1. I had to pick it up from the other thread from dec. last year. Do you use a different simple.script now?

[fvdw]

no I did not change the "simple.script"

I did not have time yet to look to this

but I do not get a message you mention

simple.script: line 1: can't open !DOCTYPE: no such file

the udhcp call works ok only the assigning of ip to the wlan0 interface doesn't happen
