Titolo: Problema con 857/877: navigazione a scatti

Salve, ho configurato un cisco857-k9 per navigare con un adsl telecom
italia (click), la navigazione va pianissimo e non si riescono a
caricare completamente le pagine da vari siti.Ne ho configurati altri 3
su adsl analoghi e non ci sono stati problemi, la cosa strana è che
con lo stesso apparato si riesce a realizzare un tunnel vpn e la
raggiungibilità dall'esterno è ottima, vi allego la conf , c'è
qualche parametro da aggiustare nella conf dell'ATM0.1?
!This is the running config of the router:

forse nell'atm0
Avevo lo stesso problema,ho risolto con 
dsl operating-mode g.dmt al posto di auto
Ma io non ho fatto il tunneling...prova e vedi se va

Forse può esserti utile inserire il gateway remoto nella
configurazione del pvc.
Questo parametro dovrebbe esserti stato fornito dal provider, cmq per
le smart di solito è lo stesso ip che assegni all'interfaccia atm0.1
però con il 254 finale (x es. se il tuo ip pubblico è x.y.z.10 il gw
sarà x.y.z.254).
Inoltre ti consiglio i comandi di monitoraggio del pvc (ubr 128,
oam-pvc manage,  oam retry 5 5 1), che in alcuni casi servono (almeno x
le smart).
Questo è un esempio:
interface ATM0.1 point-to-point
 ip address x.y.z.10 255.255.255.0
 ip nat outside
 ip virtual-reassembly
 ip route-cache same-interface
 no snmp trap link-status
pvc 8/35
  protocol ip x.y.z.254 broadcast
  ubr 128
  oam-pvc manage
  oam retry 5 5 1
  encapsulation aal5snap
Ripeto:questa conf vale x le smart, ma non credo sia molto diversa
nelle click.
Fammi sapere.
Ciao ciao
Marco

Grazie a tutti per i consigli, Mercoledì provo e vi faccio sapere
