The MTU Value needs to be changed.

Open the Configuration page>>>>go to the Setup>>>

Select BSNL>>>>>change the MTU value from 1492 to 1452>>>apply

Go to tools>>>>system Commands>>>>click save all.

What is the brand and Model of your modem?
That setting is for D-Link modem.

im using a TATA WiMax connection & it does not come with a modem .. infact i use a wireless router which is a NetGear WG624 v4 model.

Sorry,
These settings are not available for WImaX.

Try open DNS-
OpenDNS | Providing A Safer And Faster Internet

Follow their guide to set open DNS on your laptop.

BTW, how is TATA Wimax experience?
Costs an arm and a leg...Dose'nt it?

@leonjohn 2190
To change MTU
try tcp/ip optimizer from speedguide.net.


Opendns :
Start /Network /LAN or wireless link
Properties
TCP/IP
Properties

IN DNS column
enter
208.67.220.220
208.67.222.222
Apply SAVE.

Para two:

TATA WiMax connection & it does not come with a modem

Are you are getting only a RJ45 cable from the Wireless installation?
In the box in the antenna installed
is there is a modem using PoE ( Power over Ethernet )
Please confirm.

Usually the wireless router will have a configuration page (like 192.168.0.1) . There should be a option to change the MTU (The chunk size of ur data) value.

U need to change the MTU of the wireless router and/or ur PC .

To change ur PC's MTU open up command prompt

type : netsh interface ipv4 show subinterface
this will show all the network adapter's MTU value
for eg

MTU MediaSenseState Bytes In Bytes Out Interface
------ --------------- --------- --------- -------------
4294967295 1 0 447844 Loopback Pseudo-Interface 1
1400 1 273076969 8559595 Wireless Network Connection
1500 5 0 0 Local Area Connection
1500 5 0 0 Bluetooth Network Connection



now suppose we need to change the MTU value to 1452 of "Wireless Network Connection" interface, then

type : netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1452 store=persistent
