mas pripejeni v Ubuntu nastavene stejne jako ve windows? IP, DHCP servery apod?

zkus prikaz "ping ip_routeru" a pak treba "ping www.google.cz" (bez tech uvozovek) nebo sem hod vypis prikazu "traceroute www.google.cz"

Co mas za wifi kartu? Posli vypis prikazu lspci .

Neco podobnyho se mi stalo nedavno v Ubuntu. Mam Broadcom wifi (typ z hlavy nevim - nejsem ted u notebooku) ve vsech verzich Ubuntu nebyl problem, vse fungovalo. V Ubuntu asi 10.10 se najednou obejevil novy ovladac. Wifi sla maximalne 12Mb a kazdych par minut padalo spojeni. Nakonec jsem musel rucne nainstalovat stary ovladac a vse se vyresilo.

Treba mas stejny problem.
