Stuck with wireless!

[jpc2769]

I am running Intrepid, had no problems with Knetworkmanager and a static IP wired connection. Today, I tried my wireless card for the first time since upgrading to Intrepid. The wireless worked like a charm, but now I cannot switch back to the original wired connection! I need to be able to do this. I have already looked at the thread "problem with knetworkmanager(static ip)", my /etc/network/interfaces file is the same as suggested (but with my static IP address). Can anyone help with this?

Thanks

Re: Stuck with wireless!

#8 here will get you started.

EDIT: I'll speculate that you need to add these lines before the wireless lines, in /etc/network/interfaces:

auto lo
iface lo inet loopback
iface eth0 inet dhcp

Assuming you have your cable connected, all you have to do is click on the network icon in the panel (it will either be a green globe or a white cable end - when connected wirelessly, it will be four vertical bars - see picture below) and mouse on Deactivate connection... and click on your wireless connection name. You will then be running off of your wired connection.

Re: Stuck with wireless!

This is my problem: I tried to do exactly what you describe, but it doesn't work. When I do that, it goes from four bars to a turning gear, then goes right back to the four bars and the same wireless connection (I haven't seen the green globe since I first enabled wireless yesterday). If I click "disable wireless", and have my wired connection plugged in with the proper settings, I have no connection at all.

Here is my /etc/network/interfaces file:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0



iface eth0 inet static
address 10.0.0.52
netmask 255.255.255.0
gateway 10.0.0.1

auto eth0

Thanks.

Re: Stuck with wireless!

This is sole contents of my /etc/network/interfaces file:

auto lo
iface lo inet loopback

I'm connected, by cable, to my router (Linksys Wireless-G) which is connected to my DSL modem. With this, I am able to connect by wire or by wireless.

"Generally" you don't need any more than this in the file.

Re: Stuck with wireless!

Does it make a difference that I have a static IP address that I am trying to connect to with the wire?

Re: Stuck with wireless!

are you sure the netmask is correct? I would check the router, and make sure it is not 255.0.0.0

Re: Stuck with wireless!

Yep, it's 255.255.255.0. Tried 255.0.0.0 just for kicks but it didn't make a difference.

Re: Stuck with wireless!

Using wicd_1.5.6_all.deb with my Atheros card,
accessing via WPA2, and it's been working better
than network manager, as each time it's updated
back to connection problems for me.

Tried a couple of times to go back to network
manager, with the same connection problem
in a few days.

Link to web page for WICD

http://wicd.sourceforge.net/

Need to download to a folder then right click
and go with open with, scroll down and go
with gdebi-kde. Installs w/o any error message
should locate internet easily, start Wicd manager
and either right-click or left-click the icon for
what you need to be doing.

Re: Stuck with wireless!

Try Snowhog's version of the /etc/network/interfaces. First make a backup copy of your existing version:

sudo cp /etc/network/interfaces /etc/network/interfaces~

Now edit it, i.e. delete everything but the first two lines. And no, it shouldn't matter that you have a static ip address. Having said that, there are so many eventualities that one could not possibly anticipate every single one. Rule of thumb: the above works

Finally restart networking:

sudo /etc/init.d/networking restart

Plug in your cable and you should be online...

Re: Stuck with wireless!

I tried what you said, but without any luck. Anything else I can do?

Re: Stuck with wireless!

OK, let's take a step backwards for just a minute...can you describe your set up for us? some of these things may have been stated in the thread already, but for clarity, let us know as much details as possible, for instance, what router do you use, the local IP addresses of the wired and wireless connection that you are trying to use, desktop or laptop, what networking software you are using (is it the default, which is network-manager-kde)? Have you changed any default settings on your router (IE: the network IP address - which is typically, but not always 192.168.x.x - I'm guessing you have, since you are trying a 10.x.x.x address), etc, etc, etc...

Re: Stuck with wireless!

The main switch for our office is an Intellinet 24 port Nway 10/100Mbps fast ethernet switch. The wireless router is a Netgear Rangemax WNR854T. The wireless' IP address is 192.168.1.100, subnet mask 255.255.255.0, default gateway 192.168.1.1, and I am using a D-Link WNA 2330 Rangebooster G wireless card.

For the wired connection, the IP address is 10.0.0.52, subnet mask 255.255.255.0, default gateway 10.0.0.1.

I am using the default network manager (at least I think so; small globe in the lower right hand corner of the screen). Also, the wireless connection no longer works either

Can anyone help me with this?

Re: Stuck with wireless!

Networking is my area of least proficiency -- meaning I'm pretty helpless myself when there's a problem. If I were you, I would boot a Live CD, with my system connected, and see what the auto-detecting system sets up for an interfaces file. Maybe that will hold a clue for you.
