ARTICOLO: come settare l'adsl al meglio

[pieba1]

Ti credo sul PPPoA, anche se l'inserzione di user e psw non credo c'entri.

[iz7auh]

Esattamente:
Encap: PPPoA VC-Mux
MRU 1500
MTU 1500
MSS 1460

[pieba1]

Non so che dirti.

Il problema di solito è che non si riesce a settarlo sul router, ma questo non è il tuo caso.

Non è che si deve resettare qualcosa?

[iz7auh]

Non so proprio che fare, ho anche resettato il router...niente...vabbèp mi tengo sti parametri!!!

[crice]

prova a settare pppoA LLC, se l'opzione è disponibile nel router

[iz7auh]

Grazie...ci provo!

[iz7auh]

Con il PPPaA LLC non si connette proprio.....

Ciao ragazzi ho effettuato il passaggio dalla 640 alla Mega dovrei avere settato tutto bene dopo aver letto e riletto il forum mi date conferma?

Dopo nottate di ricerche...
ecco a voi x i possessori di Zyxel :

Q: How do I change the MTU size in the Prestige router?

A: MTU stands for maximum transmission unit. The default MTU is 1500, but you
can change it by using the following CI commands. To keep the commands in
memory in every reboot, please enter it in autoexec.net file.

The procedure is as follows.

1. List all iface by `ip ifconfig`. You will get all the iface configuration
about the IP network.
2. Enter `sys edit autoexec.net` and insert the following command.
3. If you want to set a iface to other MTU value, say enif0, use

ip ifconfig enif0 <ipaddr> /<mask bit> mtu <size>

4. Save the above command.
5. Use `ip ifconfig` again to see if it`s changed.

Although the Prestige allows you to change the MTU, however, we suggest you
leave the value default (i.e., 1500) because it is the most case.
If you thrink the value, many packets will have overhead because of
fagmentation and thus other routers on the way may not receive it correctly.


Buon divertimento

A me da questi risultati con la 256:

MTU = 1460
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1420
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 17040
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17040
