Иногда нет пинга по wifi.

Добрый день.

Нахожусь в Грузии, где интернет зачастую плох. Так вот, ip роутер местный выдает, но не пропинговывается иногда. В то же время, с более старого ноутбука все хорошо. Не подскажете с чем это связано?

На всяк случай lspci:

«Ничего не поделаешь, это broadcom.»

Можно попробовать поискать проблему в драйвере, что dmesg пишет во время отсутствия пинга? Ещё бы выхлоп iw wlan0 station dump посмотреть.
