Временами начинаются вылеты и/или очень большие пинги роутера (до 10-20 секунд !!! ).

Драйвер стоит wl из broadcom-sta-dkms, все прочие b43, ssb, bcma, brcmsmac — в блэклисте, могу выхлопы lsmod поприкладывать если у кого интересные идеи будут. Сама система — KUbuntu 14.04, хотя вряд ли это важно.
