August 3rd, 2011, 11:07 PM
Ok, so i tried using the ubuntu 11.04 cd but it didnt work so i had to dig out my old ubuntu 8.04 livecd. I had a computer with windows xp totally get wasted and i decided to do a clean install with ubuntu 8.04 and update to the newer version, however i cannot get the internet to connect (wired), ive tried figuring out of there is a driver problem but was not able to figure it out. Ive been searching for hours and am drawing a blank, can anyone help with this?

usage: lshw [-format] [-options ...]
lshw -version

-version print program version (B.02.12.01)

format can be
-html output hardware tree as HTML
-xml output hardware tree as XML
-short output hardware paths
-businfo output bus information

options can be
-class CLASS only show a certain class of hardware
-C CLASS same as '-class CLASS'
-disable TEST disable a test (like pci, isapnp, cpuid, etc. )
-enable TEST enable a test (like pci, isapnp, cpuid, etc. )

You need a capital C in that last command. Linux is particular about case and spacing.

sorry bout that, forgot about it being case sensitive

The avahi-address suggests the DHCP server didn't provide an IP - and avahi stepped in to "help" - which left eth0 in a subnet by itself. You can try running sudo dhclient eth0 - I suspect it'll try for awhile and come back with something like "no offers received... sleeping."

so what should i do now since every other device in the house has internet?

Also, not only what should i do next, but i am finding a lot of information about ubuntu's around 8.10 or so are not supported, does this mean i cannot use 8.04 to get internet access? how should i handle this since this is the only computer not getting internet?

I'm still doing searching (mostly because for some reason i cannot get a new boot disk to work on my problem computer) but am finding a lot of it may being a driver problem. How would i go about checking this in ubuntu?

Try Ubuntu 10.04.
