Zdravím,

v LAN sieti mám: desktop windows PC - 192.168.0.160 (kábel); debian server - 192.168.0.90 (kábel); môj debian notebook - 192.168.0.152 (wifi); otcov windows notebook - 192.168.0.128 (wifi)

Z debian serveru začnem naraz pingovať môj notebok aj otcov notebook. Výsledky si môžte porovnať:

Dáke veci okolo môjho notebooku:

do sysctl.conf som pridal riadok: net.ipv4.icmp_echo_ignore_all=0 resolv.conf má obsah:
nameserver 192.168.1.1
nameserver 192.168.0.1

Ping z môjho notebooku aj z otcovho notebooku na router sa pohybuje > 1ms, router úspešne pinguje debian server, môj notebook aj otcov notebook..


Niekto nápady, rady ? Ďakujem veľmi pekne :)

      Takéto hrozné pingy som videl len cez USB WIFI, nieje to tvoj prípad?

        Nie, nie je.Skúsil som inú distribúciu (namiesto Debian Squeeze) - Ubuntu 10.04 Netbook Remix (nič zúfalejšia ma nenapadlo :P) a tam to išlo ok: 2 < ms > 1. Ovládač sieťovej karty na notebooku je ath9k. Debian-based Linux Mint mi robí to isté, čo Debian Squeeze.. Problém v balíkoch ?

                Písal som aj sem, ale nerozumiem tomu, čo mi tým chcel povedať.Neviem, čo chcel povedať tým: "try their drivers".. aké "ich" ?

                    Takže, chlapi, veľká vdaka, vyriešil som to. Napíšem tu ako-taký postup, že čo a ako, aby táto téma mala aspoň ako-takú informačnú hodnotu. :)

                    sudo apt-get install linux-headers-$(uname -r)

                    ďalej postupovať presne podľa tohto: http://wireless.kernel.org/en/users/Download/stable/

                    Problem solved :)
