MAC address

[lynne14]

I was having trouble getting Ubuntu 9.10 to talk to cox cable and got a stupid Ideal and thought the MAC address may be the problem since I tried DNS numbers and got zip zero nada for connection . . I did not write the old one down ( even dumber ) and made it close to the MAC number on the modem . . now it does not talk to router even . . any Ideals ?

Tried DNS numbers where?
Were you using Ubuntus network manager?

I did not write the old one down

You didn't write the old what down?

You can get network info with ifconfig, route -n commands. Not sure what you need?

ipconfig only works in windows not UBUNTU ! ubuntu is Linux thats ok I have a desktop with same Realtech RTL 8139 rj-45 connection in it and I will check what the MAC addy is there and hope it works LMAO

the command is ifconfig not ipconfig

From my earlier post:

You can get network info with ifconfig,

Not reading carefully can lead to lots of problems!

its what you get for reading with glasses off . . LOL well any way I got a MAC addy and entered it will see if it works tomorrow when I re start the computer and the changes take effect maybe the desk top can be on line while the lap top is doing something else like e-mail ( desk top is hard to carry around LOL ) The Desktop does the big work like video and graphics

if you are using a router, you have no need to modify the mac address anyway, so i'm not sure why you are even messing with it, and i would recommend against changing anything with the mac address, since that is some pretty advanced network stuff

if you have a wired connection and a router, you plug into the router and it should just work, wireless might need more configuration

you need to give us more information about your setup, it is difficult to know what exactly is your problem based on your initial and subsequent postings
