-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Sometimes, maybe at boot, maybe on restore from suspend or hibernation, Thunderbird claims that it can not find host. Any host. Like imap.telefonica.net. It is not true: Laicolasse:~ # host imap.telefonica.net imap.telefonica.net has address 86.109.99.71 Laicolasse:~ # ping imap.telefonica.net PING imap.telefonica.net (86.109.99.71) 56(84) bytes of data. 64 bytes from imap.movistar.es (86.109.99.71): icmp_seq=1 ttl=245 time=26.0 ms 64 bytes from imap.movistar.es (86.109.99.71): icmp_seq=2 ttl=245 time=33.9 ms 64 bytes from imap.movistar.es (86.109.99.71): icmp_seq=3 ttl=245 time=12.5 ms ^C - --- imap.telefonica.net ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 12.544/24.176/33.936/8.832 ms Laicolasse:~ # The only cure I knew was to restart Thunderbird. I now know that also closing the lid sometimes works. This may be related to the other problem that I found, that sometimes after suspend, wlan fails, and closing the lid also makes it work again. But not restarting the router, that fails. And happens with two different routers, each at each side of the pond. So, not the router. - -- Cheers Carlos E. R.
