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

[kevdog]

Can you list ifconfig? Your interface name is not wmaster.

Can you list ifconfig? Your interface name is not wmaster.

Here is the output of lshw. I don't know how to list ifconfig.

This is your wireless driver:
driver=rt2500pci

The built-in rt2500pci driver in gutsy is sketchy. Id recommend a different driver. You have 3 options:

1. The serial monkey rt2500 cvs driver: http://ubuntuforums.org/showthread.p...ghlight=rt2500
2. Ndiswrapper + windowsxp driver: http://ubuntuforums.org/showthread.p...ht=ndiswrapper
3. Upgrade to Hardy's developing kernel and use the rt2x00 driver: http://ubuntuforums.org/showthread.php?t=646755

The first option is probably the easiest, but they all work.

Thanks Kevdog, good hints here

[walterhisownself]

You've got me on that one. Id make sure your router was not doing any MAC filtering or have any other restrictive protocols in place. Ive only read of a few others reporting chipset/router combination problems, and I've wondered if its actually true.

I'm looking through my router settings. It's funny that another laptop running Ubuntu (with a different wireless device chipset) is able to easily connect. Additionally, I have one other laptop with exactly the same wireless device chipset running Winders and it is unable to connect to the access point too.

I can see my network with "iwlist scan" or "iwlist ath0 scanning"


Here's the output:

12 Mb/s; 48 Mb/s

I can see other networks and actually the laptop connected automatically when I unplugged it from ethernet to another unsecured network because I have it in roaming mode. I saw the Network Manager icon in the upper right panel attempt to connect to any unsecured network and it was successful in joining that network.

Apologies for parachuting in like this. I've been haunting this thread for a while trying to solve an issue hugely similar to the above. Same symptoms, different hardware. The PCI card is an Encore ENPWI-G2 card with a Realtek 8185 chipset.

I've ndiswrapper'd the driver from the factory CD and loaded it.

That's about all the diagnostic I know how to run. I can ping the loopback device 127.0.0.1 but not the router 192.168.1.254. As far as I can see I don't have MAC address filtering enabled on the router and I'm broadcasting the SSID.

I've been slowly chipping away at this for a few weeks but I've finally plateau'd in terms of things to try.

Any new avenues to disappear down would be gratefully accepted.

Here's hoping',

I'm not sure if anyone is having these same problems setting up wpa_supplicant manually per the tutorial here, but if someone could help diagnose my problem that would be great --

Attached is the terminal output from setting up wpa_supplicant and the relevant driver and config information.

Thanks in advance!

You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

Hi folks,

I'm having a hard time connecting to my wireless network

I have a RT2500 (Ralink) card. If I follow the instructions set out on this thread: http://ubuntuforums.org/showthread.php?t=571188 (the "WPA with Ra Based Chipsets" bit) it looks like I'm connected to the network (i.e. the network icon on the top right of the screen shows as being connected). However even though I can connect to my router I cannot connect to the wider internet.

Doesn't make any sense to me... but I'd love any help anyone could offer.

(I'm on Ubuntu 7.04, would 7.10 be a better bet?)

[kevdog]

Ok lets just test a few things since its either a route or gateway problem.


Can you ping the router by IP address or google by IP address
64.233.187.99? If you get a response its a DNS problem

Can you also post route -n
