@ essbebe,

Please find the screen shot of Lan, Wan and SNR margin as requested.

Missed out on doing the below

Ipconfig/all and tracert

will do and update t'rw

Ps : can't open indiabroadband from home

also try MTU values like 1454 and 1492 .. change these values in your windows machine.. if possible get a LIVE CD of ubuntu and try connecting

Tried 1454 and 1492. the problem still persists.
Any other DNS Settings which needs to be changes?


Found this command to check optimum MTU on some other forum.

need to check the below
ping -f -L [packet size] [website]

Generally the issue can be because of DNS...
try using open DNS
That will be helpful for u

PROBLEM WA3002-G1
Tried Open dns and MTU change. Still some web sites not accessed.

I want to know the function of TCP optimiser, and how to tackle the problem without installing any software.

1) UTStarcom WA3002 G1 Type2

2) Hotmail not opening

3) If i don't want to install 3rd party software?

because I use both OS, XP & Leopard, I can install TCP optimiser on XP but what about Apple? that's why I would like to set-up manually....

REFERENCE :

SpeedGuide.net :: Images

You can see what parameters are changed.
Do it for Windows and MacOS.

the most important change is the MTU change..

hi guys.... I dont know what happened... but hotmail started working automatically....I didn't changed any settings..... same setting I have been using since the last 3 months, but hotmail was not working..... today I just tried and amazingly it opened. without trying MTU 1444.

Only changing broadband modem's MTU will not resolve the problem if ur network adapter's default MTU is set to 1500 then u'll still face the problem.

U need to change MTU value in ur modem and also in ur PC. Basically MTU defines the maximum chunk size of data that is sent in one go.

Most of the router will reject any packet data exceeding their MTU value with a not rechable ICMP message. Most of the time ur machin will be able to autocorrect the MTU to suit the destination router/site's MTU by reading those reply.
But some times some firewall blockes those ICMP messsage (reply) ,resulting unable to reset the local MTU value.

So it's best to set a low MTU value in ur PC to avoid the problem.


As far as I remember each network adapter has a GUID assigned to it to uniquly identify it. Find it from device manager.

Open up registry,

Now goto the following location :
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Tcpip\Parameters\
Interfaces\[Adapter ID]

Replace [Adapter ID] with ur device GUID , such as "{0569ED08-BCC7-4671-9B0B-9F722F154E4B}"

Now under that change the following keys :
Value Name: MTU
Data Type: REG_DWORD (DWORD Value)
Value Data: Default = 0xffffffff


Now If still u face the problem with MTU , try changing PPPoE MTU value :

goto "HKEY_LOCAL_MACHINE\System\CurrentControlSet\S ervi ces\Ndiswan\Parameters"

Create a new key : "0"

So that the location becomes :"HKEY_LOCAL_MACHINE\System\CurrentControlSet\S erv ices\Ndiswan\Parameters\Protocols\0"

Create the following keys under that location
Entry name Data type Value data
ProtocolType REG_DWORD 0x00000800
PPPProtocolType REG_DWORD 0x00000021
ProtocolMTU REG_DWORD the appropriate MTU size (in decimal)
