Cisco 857W Ping Alto Adsl

[proton]

Ciao raga, sono nuovo qui, complimenti al forum ed un saluto a tutti!!!
1 mese fa ho acquistato un router Cisco 857W ed avendo avuto in passato sempre dei routerini da ipermercato in questo periodo sto cercando di cimentarmi su questo prodotto veramente eccezionale
Però un piccolo dubbio o meglio un problema che non sto risolvendo, non capisco per quale motivo ho 10ms di ping in +, il mio provider è Alice Telecom 7Mb. Per es:
pingando il 192.168.100.1 ho mediamente 38ms invece provando col vecchio router ho 28ms ho cercanto anche di modificare il Mtu nel Cisco editando in ssh ma quanto pare non risponde come dovrebbe sembrerebbe un bug perchè aggiungendo un Mtu di 1000 il mio pc continua a navigare.
Vi pasto la configurazione ringraziandovi anticipatamente. Ps.Un pò incasinata putroppo per diagnosticare il caso :\

Ma tu questo router lo hai configurato a mano o via sdm?
Perchè sta' configurazione è una roba allucinante, ti consiglierei vivamente di rifarla da zero a mano!

[proton]

A mano non sono molto pratico aggiungo solo qualke stringa :\
Spero sia + chiara questa conf

La config è stata fatta al 100% via sdm!
Hai problemi con i giochi on-line?

Beh si ho cercato di usare un modo + veloce, attualmente è al 100% sdm anche se la
mia situazione del ping alla centrale rimane tale pur avendo cambiato una miriade di configurazioni e tanti comandi presi dal vs forum, non ho problemi coi game, la connessione è sempre up con delle discrete prestazioni direi, solo che mi turba il fatto che un router di 30 euro debba pingare 28ms e appena cambio col cisco il ping medio all'ip 192.168.100.1 muta 38ms chiedendomi il perchè i valori si incrementino di 10ms, inoltre ho cercato di ridurlo modificando il Mtu ma non risponde come dovrebbe lo Ios quanto pare accetta 2 tipi di sintassi ip mtu 1500 e mtu 1500 e dai test effettuati anche se volessi portarlo a 1300 la dimensione di ogni pakketto rimane sempre di default a 1500, allora mi permetto di dire: sono dei problemi che cisco si porta da sempre? correggetemi se sbaglio, grazie.

che versione hai di IOS e di firmware adsl?

magari sbaglio, ma dubito che modificare la mtu cambi la latenza dei pacchetti... casomai cambia il valore massimo del download reale...



Ciao

Certo MarcoT , la latenza e la dimensione di ogni pakketto sono differenti però qualche volta per scoprire un eventuale bug o problema cerchiamo di provarle un po' tutte

lo Ios è Version 12.4(6)T9 - FW Version: 3.0.33

...

lo Ios è Version 12.4(6)T9 - FW Version: 3.0.33

Io ho un 877W, ma forse vale anche per l'857W: quando son passato dallo ios 12.4.4 allo 12.4.15, a parità di configurazione, il ping al primo hop è calato proprio di 10ms...
ma magari è stata una coincidenza...

se hai la smartnet metti il 12.4.15.T3.

il FW 3.0.33 è embedded? non credo...
quando cambi ios provalo prima con il fw embedded, poi casomai metti anche l'aggiornamento del fw adsl.

Ciauzzz!

Uhm mi scoccia un po' sinceramente scaricare uno IoS nuovo...è un casino quel sito ufficiale...

il FW lho preso da qui ftp://ftp.cisco.com/pub/access/800/

Farò un pò di prove coi FW magari con le vecchie versioni..cercando di ridurre questa strana latenza...

[MircoT]

scaricare lo ios nuovo ci vogliono 2 minuti e altrettanti per aggiornare il router...
non vedo il problema se hai la smartnet.

[Wizard]

Confermo, aggiorna ios e firmware che non fa mai male!

[proton]

Non ho la smartnet e sinceramente non so cosa sia asd, sò entrato qui: http://tools.cisco.com/support/download ... me=Routers
Mi da il lukketto e non riesco a scaricarlo e nemmeno a registrarmi. Ma IoS se lo pagano praticamente? gh
Se potete aiutarmi indicandomi la via migliore ^^ Grazie

[MircoT]

smartnet è un contratto di assistenza che, tra l'altro, ti permette di scaricare gli ios nuovi.
per l'877w costa circa 80€. per l'857 il costo sarà simile.

prendi la smartnet semplice, così puoi scaricarti gli ios ed avere anche un livello di assistenza superiore, come il cambio hadrware entro 24 ore lavorative in caso di guasto.

il lucchetto di cui scrivi si aprirà non appena avrai registrato una smartnet per il tuo apparato.


Ciauzz!

Grazie MircoT sei molto gentile, 80 euro all'anno? vorrei sapere siccome il sito www.cisco.com è un pò confuso ^^ posso rivolgermi a qualche italiano? posso andare qui? www.ciscoshop.it boh helpme plz ^^

[MircoT]

si, circa 80€ all'anno.
Non conosco il sito che hai scritto, ma puoi prendere la smartnet da qualsiasi rivenditore autorizzato Cisco.


Ciauzz!
