RB2011 - WiFi - vyoský ping pri downloade

[hapi]

což je hlavně díky modulaci.

[eKrajnak]

Okej a mám tu jeden podstatný fakt:
Ak pingujem predvolenú bránu - čo som robil stále doteraz (čiže 192.168.0.1) tak mám ping minimálne 11ms. Avšak, ak pingujem WAN ip routra (109.236.X.Y) tak mám ping < 1ms v kľude a dvíha sa iba pri záťaži. Do 20Mbps stúpne na max. 10ms. Ak vypnem Queue tak to ide nad 60 (ale to už ste vysvetľovali vyššie, tým sa nezapodievam). V čom teda môže byť problém?

Pripájam zopár screenshotov z ROS.

Tak toto už fakt nie je normálne.

Ak zapnem video na youtube tak mám ping stále > 200ms. Už si fakt myslím, že je to HW chyba.

[telleke]

Vem dva počítače, jeden připoj přes kabel a druhý přes wifi, na obou spust ping na bránu a někam do netu a porovnej jak se to chová. Hlavně přes wifi netestuj přímo u routeru, ale třeba někde naproti v místnosti.

[eKrajnak]

Otestované. Cez kábel je ping < 1 všade (predvolená brána), aj zariadenie za routrom (SXT od mojho ISP). Cez WiFi ping kolíše. Dátový prietok WiFi nijako nevplýva na ethernetové pripojenie a ani naopak.

[telleke]

jak se to chová když spustíš třeba video z youtube. Ping dej třeba na seznam.cz na obou zařízeních a potom přes wifi spust video.

[eKrajnak]

Ako som už písal: wifi ping na bránu aj na vonkajšie adresy (napr. 8.8.8. pri záťaži (napr. youtube) rastie nad 200ms. Vplyv to na ethernetovú latenciu nemá. Tak isto keď spustím video z youtubu cez ethernetový kábel tak vplyv na wifi latenciu to nemá, tam to je stále okolo 1ms na bránu.

[eKrajnak]

Tak, ale toto už je moc. Využitie CPU: 2%. Nechápem čo ten routerboard stvára.

ako máš nastavené porty, wlan (bridge a pod.) a ip adresy v lokalke?

Nebudem to tu vypisovať, skúste sa na to prosím pozrieť cez winbox:

1. Zkoušel jsi to i bez balíčku User manager? Já jen jestli to nemůže dělat nějakej bordel. I když by nemělo.
2. Aktualizuj si bios na 3.12
3. Zkus zvednou hw retries třeba až na 15
4. Jak máš zaplé HT chainy? V read only modu to nezobrazuje takže to nevidím..
5. To eee má dost špatný signál. Zkus udělat nějaký testy když tam eee vůbec nebude

[eKrajnak]

1. Ten balíček tam je asi 2 dni. Tie problémy boli aj bez neho. Ale okej, skúsim ho odstrániť.
2. Skúsim, aj keď podľa Changelogu neobsahuje žiadne chybové opravy, iba support pre nové modely.
3. ok
4. Aktuálne CHAIN 0 (RX/TX), CHAIN 1 (RX) ... aj keď som skúšal zapnúť TX aj pre CHAIN 1 ale bez zmien
5. Hej, to EEE PC je na druhom podlaží v dome, napriek tomu podľa testov z neho je spojenie stabilné (Live streamy, Youtube, ...) všetko beží v pohode.

Diki za radu

Btw: je normálne, že upgrade biosu trvá 5 minút? Dal som povel upgrade cez winbox a CPU ide na 90% už asi 5 minút a stále neprebehol reboot.

EDIT: no jo v logu bola hlaska o uspesnom upgrade, ze ho mam manualne rebootnut
