I have a desktop and a laptop. Both XP on, and only the desktop with direct connection to the internet. I used them to make a LAN and succeeded (i am newbie, so.. it was a success 4 me)

When i installed Ubuntu (7.10) on my laptop,i connected it with the desktop (with a cable) and i chose the "enable roaming mode" option. Everything worked well... Internet->ADSL modem->Desktop->Laptop... i had internet connection!

i tried to do the same thing with a friends laptop (he has internet and i used a cable and "enable roaming mode" option) but no luck.... So i went back home, connected my desktop with my laptop and everything was ok.

On trying to find out what was wrong, i chose the "obtain ip automatically" option on the desktop (i repeat.. winXP).. Since then i cant get my laptop (Ubuntu) to connect to the internet... No matter what i do.... Obtaining ip automatically, choosing ip myself... Nothing!! I cant understand whats going on... Some help?? PLS??

Thanks, anyway!!
p.s. Sorry for my English..

I had the same setup you described except after the dsl modem netgear router, desktop, laptop. your problem is prob. addressing.you can set the router to act as dhcp. windows should find this. I run slack so I run netconfig to setup the addressing. Hope this helps.

good luck.

This may help you.

Let's see now.... All was well until you booted into windows. Now your network doesn't work.
I bet you have a realtek network chipset / card.
See this thread, the answer is in post #7, but it is worth reading the whole thread.

Problem Solved... Thank u 4 your help...

Repeating: Desktop has winXP, laptop Ubuntu..

Now...billairds---> i have no router, unless u mean i am using my desktop pc as router.. If so, i dont know how to get it to work as dhcp.. lol

tekk----> thanx very much 4 your link. I believe i ll find it very useful in the near future..

Tredegar---> i am not dual booting. Two different pcs connected through ethernet and one of them to internet via adsl modem.. Even so thanx for your link.. I dont know how i didnt find it myself.. I think "search" is a little bit of... well, u know what i mean..

Now, what i did?? Nothing! For some reason there was no connection no matter what i did. So, i went to my desktop (XP) and clicked "New Connection". I set the parameters and chose to share internet. XP then had new ips, automatically chosen. In Ubuntu i clicked "Enable roaming mode". Still nothing. So i pinged them. From the Laptop (ubuntu) to the desktop (XP) and the same.. from the desktop pc to the laptop. After that everything was fine. Like it needed the ping to work. I cant find any reason to that, and i would very much like to know why, but for now i am just happy it works.

Thank u all for your help mates....


ps
just one more question : Could u give me a link with a good "dictionary" for technical terms? I've read the interviews (NVidia and Dotzelr) and i found many things i didnt know exactly what they were and made me fell a bit . lol. Thanks again
