Периодически пропадает подключение к интернету. Mint.
Периодически пропадает подключение к интернету на linux mint. На попытку пинга выдет «Network is unreachable». Помагает переподключение к сети. Вот системный лог на момент отваливания сети:

Это следствие удаления ip-адреса с интерфейса. Смотрите другие логи, если в dmesg чисто, значит проблема не аппаратная. Может быть проблемы с dhcp, что по истечению времени выделеный адрес не удаётся продлить.
Судя из лога, как я понял, сетевой интерфейс просто берет и отваливается. Какого черта?
У меня была подобная проблема с минтом. Решилась, внезапно, перепрошивкой вайфай роутера.
Не утверждаю что у Вас те-же и с тем-же ракурсом, но в копилку знаний.
dmesg пустой. Если проблемы с dhcp, то точно не со стороны роутера. На остальных устройствах все нормально, и на винде на этом же компе тоже. Не подскажите, как обнаружить проблему с dhcp в самой системе?
Встречал сообщения о подобном, было связано с IPv6 в network manager.
Проблема с падением сетевых интерфейсов на Ubuntu 11.10
Здравствуйте! Есть проблема с периодическим (1-3 раза в сутки) падением сетевых интерфейсов, обращенных в локалку. Машина служит файл-сервером и шлюзом в небольшой локальной сети, Ubuntu desktop 11.10, samba, shorewall, dnsmasq, ifenslave и т.д.:
Linux bgps 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
04:00.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) — eth1 04:01.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) — eth2 05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03) — eth0 (на материнке)
eth0 смотрит наружу, eth1 и eth2 в бондинге (bond0) в локалку. Так вот, периодически с завидным постоянством сначала в down уходит одна, а через некоторое время вторая карта, и сеть остается без файл-сервера и интернета. Вот что сыпется в syslog:
