    Re: Linksys WRT54GS on Hardy - Almost No Action

    Do you have Ubuntu installed under VMware? Or is Ubuntu installed to its own partition?

    If you have a normal Ubuntu install (partition), then I think your routing table is really messed up at this point. It doesn't even show a gateway for your eth0 interface (just 0.0.0.0). But if you are using VMware, then I don't think I can help you, because I'm not sure what your routing table should look like under VMware.

    Just to clarify, were you able to use the internet fine in Ubuntu until you changed the router's address? Or were you only able to communicate with the router?

    Re: Linksys WRT54GS on Hardy - Almost No Action

    Wow. Fast replies. I appreciate that.

    I have 64-bit Ubuntu installed on a dual-boot system with WinXP. What we're talking about here is the Ubuntu installation with VMware installed on top of it. I'm running WinXP in a virtual machine in VMware.

    Each operating system is on its own physical drive. I have drive C and other Windows partitions on one hard drive, and I have / and swap for Ubuntu on another hard drive.

    I had previously had some of the same problems, but then it had magically started working. I was able to go online with all installations: with dual-booted WinXP, with WinXP in the virtual machine, and with dual-booted Ubuntu. Then it just stopped. Now it has magically stopped. But only in Ubuntu and in the WinXP virtual machine. I can still go online in the WinXP dual boot.

    Re: Linksys WRT54GS on Hardy - Almost No Action

    Ok, how about going into network manager, make sure only your eth0 interface is enabled, set eth0 up with a static IP address (instead of DHCP), and then also specify your gateway as 192.168.2.1. That might give us a clue what is going on. Try pinging your router and checking the routing table to make sure you really are using 192.168.2.1 as your gateway after setting things up in network manager.

    Also, are you running VMware while trying these things in Ubuntu? It would help to keep VMware closed down to make sure it is not interfering at this point.

    Re: Linksys WRT54GS on Hardy - Almost No Action

    I went into Ubuntu's System > Administration > Network. This opened a Network Settings dialog. On the Connections tab, I clicked Unlock and then Wired Connection and then properties. "Enable roaming mode" was selected and everything else there was grayed out.

    I unselected "Enable roaming mode" and set Configuration to DHCP. That gave me a "Changing interface connection" box. When that box was gone, I tried but failed to go online, using Firefox in Ubuntu (i.e., not inside VMware). I went back and changed it from DHCP to Static IP Address, and typed in 192.168.2.1 for IP address. I clicked on the Subnet Mask box, and it defaulted to 255.255.255.0. I typed 192.168.2.1 in the Gateway Address box. I realized the IP address probably had to be something different, so I went back and changed that to 192.168.2.100, since that was what I was seeing for Ethernet Interface (eth0) in Ubuntu's System > Administration > Network Tools > Devices > Network Device. I clicked OK. Again I got the "Changing interface connection" box. I tried again to go online. Still no luck.

    I took all these steps with VMware still running, because unfortunately I have a process underway there that I can't interrupt. I will try again with VMware shut down, later tonight or tomorrow. In the meantime, if I have gone astray on any of the foregoing steps, kindly set me straight. Thanks again for your help.

    Re: Linksys WRT54GS on Hardy - Almost No Action

    I left the settings on Static, as described above, and closed down VMware. I let the machine sit overnight, turned on, and tried going online again this morning. No problem!

    Network Tools, at this point, shows three of the four devices listed previously:

    Loopback Interface (lo)
    Ethernet Interface (eth0)
    Unknown Interface (vmnet1)

    My vague impression is that the vmnet8 device was the result of a mistake I made during installation.

    If I start up VMware, and do nothing more, there are still only the three items listed above, and I am still able to browse online. If I power on a virtual machine in VMware, same thing: still good. If I start up Internet Explorer in that WinXP virtual machine, I am able to go line that way too, and there are still just those same three items listed in Network Tools.

    If I change Network Settings to DHCP, Network Tools still shows those three items. I am still able to browse online using Internet Explorer within the virtual machine, and likewise in Firefox in Ubuntu.

    It seems the problem may arise when something causes that fourth item, vmnet8, to come to life. I may be happier without it. Is it possible to locate and eliminate it?

    That's great news you have it working. I was definitely suspicious that VMware was involved.

    As I mentioned before, unfortunately I can't help you with your VMware problem of creating new network interfaces because I don't use VMware. I'm sure there is a manual way of deleting that network interface within the right configuration file(s) in Ubuntu, but that probably won't prevent VMware from creating it again. Really you should try to figure out under what conditions VMware creates that additional interface.

    But at least you have the problem narrowed down now, so if you have any similar problems in the future, you will know the likely culprit (VMware) and have a good idea how to troubleshoot it.

    Question Re: Linksys WRT54GS on Hardy - Almost No Action


    I hope you all don't mind I read what every one said but I need the ABC's of it all. At this point I figure that I don't need the CD that comes with the router. Right?
    So how do I install it? I am not using windows at all. SO do I just install the device and pray? Can some one tell me where to find this info?
    Thank you
