How To: Manual Network Configuration without the need for Network Manager

[wwastro]

Your scan results are not detecting any nearby networks!

daparker

You could post the results of lsmod to find the driver.

This computer is sitting very close to the router, and the wireless signal is clearly detected. Thus the output from

iwconfig

is (practically as quoted before):

lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

eth1 IEEE 802.11g ESSID:"NETGEAR" Nickname:""

while the output from

lshw -C network

is

- note that:

(1) the wireless card driver is iwl3945 (in the original Windows XP setup it was iwp3945, and this also applied for Gutsy);

(2) eth1 sees the radio signal but itself seems to be associated with a wrong MAC/physical address for the wireless interface (which should be
00:18:de:94:65:62, judging by the past Windows/Gutsy setups etc, but this is now somehow associated with wmaster0).

For the record, the output from lsmod is:

Any further insights, kevdog? Thanks.

PM chili555 -- he has an intel card and is an expert with intel setups. He is very responsive -- perhaps he can shed some light on the situation. dmizer might be another good resource (can't remember if he runs an Intel card or not). He's a forum mod now, so I'm not sure if he responds to PMs (he used to) but I would give it a try. He is also an excellent resource. Hopefully they can shed some light on what is going on here. There was some problem I think I remember chili555 talking about during the Gutsy -> Hardy crossover with intel cards. I just can't remember what he said??

Best advice

Figure out the interface
Try an unencrypted connection
Use an ESSID with only letters or numbers -- no spaces or crazy characters.
Broadcast the Essid

Make sure you can see your router with
iwlist scan

Hmm. maybe you could provide more info.

Hi I now have, Wireless connection to 'wirless name' (100%)
I still can't get onto the internet but found message in /var/log/syslog laptop ppoe - discovery: Time out waiting for PADO packets
What information do you need and where would I find it? Thanks

And another happy HP presario v3000 (64x2) WiFi user.
A BIG THANK YOU to kevdog. =D>
It really works.

Hello Guys/Gals...Another post sent me to your instructions because my Network Admin was not responsive. I followed your commands and have posted the results. I have a 2002 Dell Inspiron 2500 and am using a Linksys WRT54G Router w/ a Linksys WPC54GS pcmcia card.
I am currently connected with the same card and router on my other Dell laptop using XP. I first tried to provide the status and then the commands to connect to the device. It appears that one of my devices is sleeping. Any help would be greatly appreciated, been working for a couple of weeks just to get this far. Thanks.

PS. I am running Gutsy Gibbon on the above 2500 having done a complete wipeout of XP..

[stackman1]

There is already a pid file /var/run/dhclient.pid with pid 134519120

Just wondering if I am causing a problem by using the same nic card between my XP laptop (this one connected to the web) and my Gutsy Gibbon machine. Do I need to rest the router or something if I pull out the pcmcia card and then insert it and boot up the Ubuntu machine?

Thanks I now have 'wireless connection to wireless name (100%)'.
I get a connection timed out when trying to send email or get onto the internet and
/var/log/syslog laptop ppoe -discovery:Time out waiting for PADO packets.
What kind of information do you need.

[kevdog]

kinrose -- I dont know what PADO packets are. Have you googled the topic?


Stackman -- Upgrade first to the latest ndiswrapper version -- I think it is 1.52 if you have not done so. To find out your current version:

modinfo ndiswrapper

[d.avid]

Hi kevdog, you asked me to post my 'iwlist scan' result (which I did, first post on the previous page). Can you help me getting WPA to work?

(see my first post in this thread: http://ubuntuforums.org/showthread.p...62#post5481462
second post: http://ubuntuforums.org/showthread.p...20#post5483320 )

I would appreciate any help
