| 1135992 | 2010-09-12 03:19:00 | No, I still have no internet connection.OK. In fact, after adding the lines to /etc/network/interfaces, the icon for network connectivity disappeared from my panel. Strange, no?That's supposed to happen - adding eth0 to this file should override the default config mechanism Ubuntu is using. Noting it didn't fix the issue, you can remove these lines again. When you tried to renew the dhclient lease, did this temporarily fix things, or not? No it did not.When you run dhclient, what output is displayed? I have no router.If you don't have a standalone router, you probably either have a router built into your comcast modem, or your comcast modem is operating as a straight bridge, and the lease comes from comcast directly. Does rebooting your modem, then running 'sudo dhclient eth0' 5 mins later solve things? Can you describe your physical network? How many devices are accessing the internet via this modem, and how are they all connected? Is the Ubuntu PC connected directly to the modem via a cable, or are you using some other method? |

| 1135993 | 2010-09-12 10:36:00 | A few months ago I had a similar problem with my newly installed Ubuntu 10.4 in that I could not connect to the internet and, again like you, Erayd replied. His patience over more than a week, his concise questioning and undoubted knowledge had my problem fixed and Ubuntu has run without fault ever since. To me he is a tremendous guy and I am still grateful to him for his help. :clap | Xam (11850) | ||

Is there a reason for this? |

| 1135995 | 2010-09-12 10:58:00 | Looks like you are using IPv6 rather than IPv4. Is there a reason for this?That address is a zeroconf address - it's automatically generated by the system in the absence of any proper ipv6 configuration information. The entire fe80::/16 network space is reserved for this purpose. In most cases it has no impact, and can be safely ignored - it's not related to the OP's problem. If you're interested, you can find a fairly useful overview of the various zeroconf implementations here (en.wikipedia.org). |

I just now edited my 'Auto eth0' connection to ignore IPv6 and, viola, I got connected. :clap Thank you all for your help. Now if I could figure out how to scroll-wheel a page at a time. :rolleyes: |

| 1135997 | 2010-09-12 12:21:00 | Good to know it works now! Strange though, as Erayd pointed out, it shouldn't make any difference... |

Interesting to hear that it disables ipv4 by default though - it shouldn't be doing that... probably yet another useless decision by the Ubuntu packagers :(. Thank you all for your help.No worries :). Now if I could figure out how to scroll-wheel a page at a time. :rolleyes:Believe it or not, this is actually possible. Depending on where you're configuring your mouse, you should be able to set a 'per-click' scroll height; if you bump this up you'll be able to get it to scroll approximately a page at a time, although you won't be able to get it perfectly exact. |

Well, mine works for me, I have 10.04 running, my router does not support IPv6 yet I get the link-local address for IPv6 as dkjMusic does. |

| 1136001 | 2010-09-13 03:07:00 | The zeroconf address is assigned by the local system, not by the router. Yes, I know. I suppose what I wrote didn't make much sense. What I meant to say is that even though my router has no support for IPv6, and Ubuntu supports it, it does not cause IPv4 to fail for me. |
