  Kedves Nagyérdemű!

  Az alábbi témában kérem segítségeteket. Van egy WDR3600 routerem,a min OpenWrt vargalex v1.1.7 r35342 (kernel 3.7.4) fut már egy pár éve. Egyszer beállítottam, azóta teszi a dolgát.

  Az utóbbi két napban viszont alkalmanként elveszik pppoe kacspolatom, így elveszik a net. Aztán egyszer csak újra elérhető. Éljünk azzal a feltételezéssel, hogy szolgáltató oldalon (digi) rendben van a dolog. (elég macera kiikatni a routert és közvetlen gépbe csatlakozni, így ezt még nem ellenőriztem 100%-ra, de "területi hibáról" nem tudnak.)

  A log részlet így néz ki

  Amit észrevettem és böki a csőröm, hogy mintha valaki megpróbálna bemászni a routerbe. Aggódjak? Ez okozhatja a wan elvesztését? Mit tegyek ellene?
