First, thanks for your long post! I appreciate it.
Btw, the router is a Netopia ADSl router, but the model doesn't show when I log onto it.

Opps! Should have asked. I assumed your wireless router was one supplied by a cable tv vendor, like roadrunner, cox, or earthlink.

Are you using Kppp, which is for ADSL modems, to make your connection?

First, thanks for your long post! I appreciate it.

I checked the router config, which looks ok as far as I can see. The DNS addresses are as specified by the ISP, except they are interchanged, primary and secondary. I don't see how that can matter and, in any case, I have no idea how to change them. Btw, the router is a Netopia ADSl router, but the model doesn't show when I log onto it.

I emptied (completely) resolv.conf and rebooted. (I don't know how else to get knetworkmanage to do its thing, since it's already running after reboot.)

Same result: $ cat resolv.conf
# Generated by NetworkManager
nameserver 192.168.1.254

This is the address of the router itself.

Am I condemned to rewriting resolv.conf every time I boot? Why did this "work" with Jaunty, but does not with Koala? (I do not know what was in resolv.conf in Jaunty.)

Hi.

I think that is a DNS problem, not IPv6. I'm not sure.

What kind of IPs are you using? DHCP (automatic from the router) or static (fixed by you in each equipement)?

I put a Google DNS server address in, as your link suggested, and DNS lookup by Thunderbird is super-fast now.

You can try the following:
change the file resolv.conf with the parameters that works fine and change the file permissions to just only read permission.

Have you tried disabling ipv6 in thunderbird itself?

Go Edit > Preferences > Config Editor
and look for network.dns.disableIPv6 make sure it's set to true
No more ipv6

Now there is a good idea! Note that the config editor is rather buried in "Preferences", way out in the "Advanced" tab.

Btw, setting the resolv.conf permissions to read-only had no effect.
