    Limited Internet Connectivity

    Hi,

    Im completely new to linux. I've been booting using the LiveCD and everything is fine except for the internet. I have Comcast hi-speed using an arris modem. The browser lets me visit some sites (google.com (and everything affiliated with google, like gmail), www.ais.edu, and a few more -- i found these by just doing random guesses in the address bar) but nothing else loads. Like, when I do a google search I can't load any of the pages that show in the results.

    I did a search here and noticed someone asked to do a cat /etc/resolv.conf settings and this is what showed:

    search hsd1.wa.comcast.net.

    nameserver xx.xx.xx.xxx
    nameserver xx.xx.xx.xxx

    When I went into the network settings panel, my ip address looks correct, so does the gateway, and dns servers (i know this because I am comparing them to what "ipconfig /all" gives me in windows) -- I mean, after all, I am getting the internet; I just can only access certain sites for whatever reason.

    Now, when I look at the connection settings I believe everything is alright -- I mean, I am using DHCP and everything is set to "automatic discovery".

    Now, for some history I had MandrivaOne installed for a few days about a week ago and I had the exact same problem. i could get google and a few others but thats it. Also, the network monitor showed I was connecting at a very low rate (like 1-2kbs) even thoug the pages seemed to load just as fast as in xp. Well, since I couldn't get it to work, I uninstalled Mandriva.

    Now I came across Kubuntu today and wanted to give it another go. So i downloaded it and decided to see if the internet would connect before installing it but, as noted, no luck.

    I *really, really* would like to install and keep kubuntu, so please help me someone

    Sorry for the long post, but I need some help!!

    You can try to disable ipv6, it's known to cause similar problems with some ISP.

    https://help.ubuntu.com/community/We...ngSlowIPv6IPv4

    In that link you have two possibilities, disabling it system wide or only in firefox.

      So i installed Kubuntu so that I could do that IPV6 disabling (I had done the firefox one before when I had mandriva one installed). I did it in both places and still, it isn't working -- only connects to certain websites.

      what else could i try? I was using the usb interface (on the modem) in xp but it wouldnt work in linux so i switched to the ethernet connection -- is there anyway to make the usb connection work?

      i have an arris modem but i don't know where i would get the linux drivers for it.

        Most of the usb modems do work.

        Have you tried to put your own dns ?

        Your ISP has probably some one that you can try. If it works with direct modem connection, and not as a router, it's possible that the router is acting as a bad dns.

          i have the same problem. I had noticed that if I cant get a site on the kubuntu box, I do the same search in google on one of the xp boxes on the network. I can then connect to the relevant site found by google on the xp box. When I then try again to connect to the same siite on the kubuntu box, it does connnect.
          So it would appear to be a DNS or proxy or caching type problem.
          I am using konqueror. Have firefox also, but had not tried to connect to a problem site with it instead of konqueror.

          Also noticed that it is an intermittent problem. Sometimes it connects, sometime not.

          I did last night add my ISP's DNS servers on to the kubuntu box, but on the dns server page on the network settings page from k menu, systme settings. This is possibly the wrong place though, maybe that is just for the LAN and not for WAN. Will have to look at konquere/firefox options later, when I am back on the machines.
          Excuse bad spelling, formatting here, I am doing this from the phone, while in bed, with evil looks from the girlfriend

            Just checked again, and the DNS servers from my ISP that I added seems to have disappeared again on re-boot. It stays there until the PC reboots, then they revert to just the local 192.168.1.1

              What happens if you disable this entry (by adding a leading "#")?

              Re-do the editions, than re-set the file to "read-only": sudo chmod 444 /etc/resolv.conf 8)

                OK, thanks

                What would the code be instead of 444 to set the file back again to read/write?
                And more importantly what are thoses codes called. I tried to search for a list of them but difficult if you dont know the name of the thing you are searching for

                  Just been using a Ubuntu 7.04 live CD on the same machine, and these problems of poor internet connectivity just dont appear.

                  Same goes for the local network of Windoze boxes, instant browsing of them, with no samba config difficulties
