    Local Networking not Working with Wireless?


    O.k., I've got a weird one for you guys this time. I just reinstalled my linux system which was working fine with an upgraded kubuntu 7.10 just today. When I reformatted and did a clean install, I found that the restricted-manager was offering a new driver for my wireless card (BCM4318: I formerly used ndiswrapper). I installed it and almost jumped for joy when it connected easily and I updated my system with apt easily. Before the update, I used samba to back up several files I need on a server at 192.168.1.122 that usually just stores music to save space on my laptop. However, when I went into remote places->Samba shares I got an "unable to find any workgroups in your network" error. I had played with samba earlier in the day, but when I was running from the livecd,it responded just fine. Eventually, I resorted to pinging my server as you will see below, but I got a "host unreachable". I figured there might be a problem with the new driver, so I sullenly blacklisted it and installed the ndiswrapper version. No luck there either. I tried to ping my router at 192.168.1.1, but that didn't respond either... I've played around in my /etc/network/interfaces for a while and still couldn't figure it out. Why in the world can I not find my local network (including router), but I can get to google (and this post) just fine?

    Code:
    alaric@alaric-laptop:~/.Wireless$ cat /etc/network/interfaces
    auto lo
    iface lo inet loopback
    address 127.0.0.1
    netmask 255.0.0.0
    
    
    iface eth0 inet static
    address 192.168.1.121
    netmask 255.255.255.0
    gateway 192.168.1.1
    
    auto eth0
    
    iface eth1 inet dhcp
    wireless-essid *****
    
    auto eth1

    hmm... I commented out my ethernet settings in /etc/network/interfaces, set my wireless network to static, and restarted my networking and it works now. Problem solved.
