Taková kacířská myšlenka - nemůže být nakopnut etherent port (až už v Sagemu nebo TP-Linku). Zkrátka začne blbnout signalizace a padá t třeba 10/100/1000, half/full duplex, .... Se podívej před rebootem do logu, zda se dá k tomu někde dostat. Reboot ti udělá často i reset ethernet iface a po resetu se to na chvíli vzpamatuje...
Pokud je tam v místě někdo s minimem inteligence, tak při dalším ublbnutí instruuj, ať na chvíli vytáhne Ethernet kabel na pár sekund mezi těmi krabičkami, zda to náhodou také nenapraví situaci.
Archer C6 ma syslog a log je mozne ulozit. Avsak ked ho ulozim, tak tam toho je prapodivne malo, takze ho sem mozem kopnut. A aj tie datumi su nejake divne (z dnes a potom z pred vyse mesiaca kusok).

Ano, myslim, ze ty ludia co tam su, tak by dokazali v pripade problemov reinsert patch kabelu medzi sagemcomom a archerom (avsak, niekto by im musel ukazat, ze ak to vytahuje z portu, tak musi podvihnut ten cuplik na RJ45 konektore)

Ale najskor to pojde az po sviatkoch.
Inak zakaznik sa do Sagemcomu v bridge mode nijak nedostane, takze tam nemozem nic.
Ještě mě napadá, že takhle nějak může vypadat kolize adres. Na infrastruktuře providera by to samozřejmě bylo překvápko.
A pokud "pomůže restart", tak mě ještě napadá, zda by se dal navodit restart PPPoE relace, bez restartu fyzického linku...
Restart PPPoE sa navodit da, ale musel by som byt v LAN sieti (pretoze je tam button connect a disconnect (skoda, ze tam nie je reconnect)). Ak by som dal disconnect, tak by som sa odrezal.
A este jedna vec. Vzdy (zrejme po reboote) naskoci cas UTC 0. Ja to vzdy zmenim na UTC +1 a ulozim (vid najnovsie riadky v logu).
