Nestabilni internet pres WLAN i drat v 15.10
« kdy: 15 Listopad 2015, 10:22:01 »
Dobrý den,,

EDIT - začínám omluvpu a prosbou adminovi o přesun do příslušného non-LTS fóra !

prosím o radu v ideálním případě srozumitelnou i pro mou 70letou maminku, neb je to její PC, nebo aspoň pro věčnou začátečnici co není příliš doma v linuxu (t.j. mne)  :-[
Počítač je  Asus All-in-one A4310, čistá instalace Ubuntu 15.10 na nový stroj koupený bez OS. Po instalaci zcela bezproblémový zkušební provoz přes drát i wifi s jakýmsi modemem-routerem od Zyxelu (tuším, že P-660HN-T3A, ale teď jsem od něj 100 km a nemůžu se podívat).
Po převozu na místo finální instalace hladké spojení s modemem-routerem  (opět jak přes wifi, tak přes drát), ale po náhodném intervalu cca od 5 min do hodiny vypadává spojení s internetem, přičemž počítač zůstává připojený k modemu.. Tedy: síť hlásí "připojeno", ping na router funguje, http připojení na router také, v nastavení routeru nic podezřelého, ping na jakoukoli adresu vně routeru zůstává bez odpovědi. Pomůže (někdy krátkodobě, někdy i dlouhodobě) restart nebo i jen odpojit ručně drátové připojení a zase ho připojit. V této chvíli mám zakázané wifi spojení, aby se věci dále nekomplikovaly. Ráda bych spolehlivě a bez výpadků rozchodila aspoň drát.
Modem je Comtrend VR-3026e v2, v době výpadku spojení na Asusu se přes něj nadále hladce připojuji k internetu androidovým tabletem.
Karta v počítači je:
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 11)
Připadně pro wifi:
04:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)
Systém je aktualizovaný, co jen to šlo, takže tuším, že v driverech té karty to asi nebude. Firmware routeru nebyl aktualizovaný dost dlouho.
Dole připojuji velký kus syslogu , měl by v tom být min. 1 výpadek se znovupřipojerním.
Prosím o radu, co s tím. Napadá mne:
- aktualizovat firmware routeru
- něco provést s nastavením sítě - otázka je co, teď je vše na defaultech
- ještě něco jiného?

Budu vděčná za radu.

Re:Nestabilni internet pres WLAN i drat v 15.10
« Odpověď #1 kdy: 26 Listopad 2015, 15:58:23 »
Ač nikdo neodpověděl, připojuji update: nakonec hladce vyřešeno výměnou modem/routeru, který už opravdu měl hodně za sebou.
