Pripojeni v Ubuntu 9.04 a 10.04 jede mizerne

[mach]

Ahoj,

pripojeni v Ubuntu ke Klfree mi jede mizerne (co to znamena viz nize). Vsechny jiny kombinace:

- Klfree ve Windows
- ne-Klfree ve Windows
- ne-Klfree v Ubuntu

jedou naprosto bez problemu. Cili Ubuntu si nerozumi s necim specifickym pro Klfree. Chova se to tak, ze pripojeni jakztakz jede a nekdy se "zasekne" a stranku uz nenacte. Kdyz se odpojim a zase pripojim, tak to zas trochu jede. Nasledujici vypis pingu je naprosto typicky:

Mam router Asus wl500g.

[skudlik]

Mas to pripojeny pres wifinu na tom aususu, nebo je ausus klient do klfree a dal to jede po ethernetu? Pokud jedes pres domaci wifi, zkusil bych to pres kabel, jestli to bude delat totez. Ty pingy zlobej jen ven ? .. Bylo by dobre to propingat postupne od toho tveho routeru cestou dal, aby se dalo zjistit, kde k problemu presne dochazi.

Jo a taky me trosku zarazi, ze pises ze mas "router" (dalo by se ocekavat, ze budes natovat a pouzivat pro vnitrni sit nejaky vlastni rozsah), ale podle tech pingu mas na PC IPcko primo z rozsahu klfree .. 

Takze prosim trochu lepe popsat jak je to presne zapojene. Evidentne to, ze "klfree jede mizerne" je zpusobene tou ztratovosti paketu, takze zjistit, kde se pakety presne ztraci.

Diky, diky! Mam to pripojeny pres ethernet kabel. Sitovani moc nerozumim, ale to nastaveni, ktery davam Ubuntu je nasledujici:

IP adresa: 10.102.39.147 (semtam to testuju s .39.148, to je verejna)
Maska podsite: 255.255.255.248
Vychozi brana: 10.102.39.145
DNS: 10.102.0.252

Takze tam NAT asi neni. Problem je, ze se to chova dost nahodne. Casto ten ping projde bez problemu, ale nekdy se zasekne. Stejne jako cokoliv (nacitani stranky, stahovani updatu, ...) Kazdopadne zrovna ted jsem napingoval tohle na google.com:

Na tom routeru bezi Linux, muzu se na nej telnetnout, kdyby to bylo potreba. Nevypada to, ze by se pri techhle problemech neco novyho (tykajiciho se sitovky) objevovalo v dmesg. Jeste vypis lspci:
