Wifi on Panda?

[moon127Member]

I’ve just installed Geexbox 3.0 on my ARM Pandaboard and have it working well using the Ethernet port.

I’d like to connect to samba shares using wifi but despite reading the docs on configuring /etc/network I don’t seem to be able to get wireless connected.

Does wifi work on Panda?

[tomlohaveModerator]

use dhcpc instead of connman for wifi on panda (edit /etc/network), it should work.

[a649mMember]

shouldn’t it be “udhcpc”?

Have the same issue and tried it with dhcpc before which didn’t work and checked the documentation later that I forgot the ‘u’…

Haven’t tried it since then.

 

I have another question to WLAN on pandaboard: should the WPA key be in plain text or in hex format?

[tomlohaveModerator]

right : udhcpc.

for WPA : I use the hex key

[a649mMember]

Still doesn’t work for me.

Is it a driver problem? The displayed MAC address (via ifconfig wlan0) is DE:AD:BE:EF like it is not initialized.

Other systems (e.g. Linaro Ubuntu build) show the MAC correct)

Is there something I could do about this?

[tomlohaveModerator]

did you install package udhcpc ?

[uffeMember]

I also have problems with getting the wifi to work on the pandaboard. Changing to udhcpc did not help, although I did not do any attempt to install it. Could you please enlighten on how to do that?

[tomlohaveModerator]

install the package udhcpc first then it should work

[uffeMember]

When I try “opkg install udhcpc” it says I already have the newest version.

I’ve now also tried all settings combinations I can think of in the ‘network’ file without success. This is the content of my best guess:

Ok,

let me check,

I have pushed some changes to xbmc, now we use version 12.1 for panda too

I will retest wifi on panda

 

[tomlohaveModerator]

wifi works out of the box here.

Thanks for all the information. It still does not work though, I’m afraid… My theory is that the wireless module is loaded too late. I see from your post that already at 10 seconds the connection is made. On my pandaboard it takes 40 seconds just to load it:

# [   40.555480] wl12xx: loaded

I have pandaboard rev A3 (not ES), can that make a difference?

[tomlohaveModerator]

Can you start net-udhcpc manually and post the results ?

 

[uffeMember]

I guess you mean “udhcpc”? This is what I get (last three rows are continuously repeated):

# udhcpc -i wlan0
udhcpc (v1.21.0.git) started
Sending discover…
udhcpc: sendto: Network is down
Read error: Network is down, reopening socket
Sending discover…
udhcpc: sendto: Network is down
