Ahoj,
mam problem s vypadavajici wifi. Na notebooku jsme normalne pripojenej k
siti (wifi) a znicehonic ztratim signal. Problem je v tom, ze wifi
zustane pripojena k AP, ale nepingnu se ani na GW. Po nejaky chvili
(neumim presne urcit) se na GW dopingam, ale odezva je desiva (nekolik
malo sekund), po dalsi chvili uz je pripojeni OK. A to se mi nekdy
nestane cely den, nekdy nekolikrat za dopoledne. Restart netif service
problem "opravi", nekdy se znovu objevi, nekdy ne.
Proste nejsem schopnej nijak rict, kdy, proc a jak k problemu dochazi,
syslog mlci. Moje otazka tedy zni: muzete mi nekdo poradit, co a jak mam
monitorovat, abych se dozvedel kdy a proc k problemu dochazi?
