Hi,

I'm having problems with ubuntu recognizing ethernet connections. When I go to manual configuration network settings window only the point-to-point connection option pops-up. I have a dell inspiron 4000 laptop that had a great wireless connection when using Windows. It's now hooked to a router with a ethernet cord and Ubuntu's not accessing it.

I've read and tried some of the suggestions given to other people who listed similar problems on the forum, but I'm still stuck.

please help!!

try assigning the eth0 an ip one highter than the highest XP box, with the same DNS and Gatewa y address to see if you have internet
have no idea how to do this

I donīt use wireless,so Iīm not an expert but it look like you need driver for your wierless card.Look here (https://help.ubuntu.com/community/WifiDocs/WiFiHowTo) for more information.

have you tried

ifconfig eth0 up

this will "initilize" your device.

Thanks for replying!

I tried ifconfig eth0 up and ifconfig eth1 up and got the "device not found" answer.

I also tried the following today....


ifconfig inet addr

Is your ethernet built in on board? or discrete?

If on-board, your ubuntu is having problem on recognizing it.. what model is your ethernet card. or board?

I have no idea what model or type of ethernet card I have...

should I just try to change the hardware and see if that works? is that someone i would likely be able to figure out how to do myself?

also, i had previously tried buying a wireless notebook adapter and the software wasn't compatable with ubuntu. is there some type of wireless adapter that's software works with the ubuntu os? (I tried the third-party software input window and it wouldn't work).

thanks!!!!!!
