Upgrade to 9.10 - slow loading of web pages- IPV6 Prob?

Asked by Mike Cummings

After upgrading to Karmic 9.10 from 9.04, i found that web pages in both Firefox and the Google Chrome unstable version I am playing with were having problems resolving the addresses. I quickly found that this was an issue with all the apps that access the internet. This was not an issue on 9.04.

 In a forum on Ubuntu, I found an instruction to try and disable IPV6; I inserted the following line into the menu.lst line for my kernel 26.31-14-

 ipv6.disable=1.

 This worked beautifully, as long as I used legacy grub. I have since upgraded grub to grub2, as I read somewhere else that that would solve the problem, as well. Now I am back to the same problem- pages are very slow to resolve.

Is there a more permanent solution to this problem outside of disabling IPV6? Was there a change made in 9.10 that causes an incompatibility with my network? I am hard-wired to a D-link DIR-615 router connecting to an Earthlink DSL modem, using DNS relay to the Earthlink DNS servers. The connection info show the address of the router as the primary DNS. My other (Windows) computers on the network have no problems, and Juanty worked fine.

Any ideas?.

How are you getting your IPv6 connectivity?

Natively, or through a transition mechanism? If the latter, which one (Teredo, ISATAP, 6to4, tunneling, etc)?

Not sure.. networking is still a bit of a mystery to me. Is there a way to determine this? Thanks for answering so quickly.

I know this will not solve the general problem..
But it will solve the problem with Firefox (at least it solved my problem, now i open faster a lot)..

Just some firefox tweaks..
In adress bar write about:config.. It will ask you are you sure you want to change...blabla... contunue..
In filter bar type "network.http.pipelining" (without quotation marks ofcourse), and double click the value that comes up (it will turn from false to true.
Then type "network.http.pipelining.maxrequests| in filter bar, double click, and set it to 10.
Type "network.http.proxy.pipelining" and set it from false to true.
Also change "network.dns.disableIPv6" from false to true.
Now it's time to create some new preferences..
Right click on an empty(white) spot, and select New->Integer. Put the name "nglayout.initialpaint.delay" and set the value 0.
Create another integer preference, name it "content.notify.backoffcount" and put 5 as value.

Now restart your browser (close and open again).. It maybe hasn't solved your problem generally, but hope that your Firefox opens a lot faster...

This has improved the performance of Firefox, but the problem remains with my other net apps. Thanks, but I am still looking for a total solution, or at least a reason for the change.

Ok let's try this..
On the top panel, on the right side (left from date&time) there should be an icon for your connection..
Right click it..There should be an option like "edit connections" or "configure connections" or something like that... I can't tell you exactly since im not using English version. When you open it, try to find your connection in one of the 5 tabs, select it and press Edit. Go to IPv6 tab and put Method to Ignore..

See if that works..

Sorry for the double post, but i found another possible solution..
In /etc/default/ there is a file called grub..
Open it.
Find the line
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
And replace with
GRUB_CMDLINE_LINUX_DEFAULT=”ipv6.disable=1 quiet splash”

The only thing is, the file is read only..
Since im not so experienced with Ubuntu (switched from Vista 2 weeks ago), don't know how to turn off read only..
Should work..
