Thread: Some assisstance required.

I own an MT 841 modem, and my plan 2mbps at 500 per month. Over the last 3 days I'm unable to display any internet page.

My modem status :

ADSL link green (not yellow) and yet stable.

A call to 1504 yielded in a stable yellow light after creating a PPPoE connection with username and password. And yet the internet did not work. I was then guided to Address Pool in the DHCP and instructed to change values and many other steps which did not solve my problem. I chanced upon the Diagnostics and when tested my active PVC, I was given this.

Modem Connection Test
Testing Ethernet connection

PASS
Testing ADSL line for sync

PASS
Testing Ethernet connection to ATM

PASS
ATM Connection Test
Testing ATM OAM segment ping

FAIL
Testing_ATM OAM end to end ping

FAIL
ISP Connection Test
Testing PPP server connectivity

PASS
Testing PPP server session

PASS
Testing authentication with server

PASS
Validating assigned IP address

PASS
Internet Connection Test
Ping default gateway

PASS
Ping Primary Domain Name Server

PASS

When I notified the helpline about this issue, they sounded lost and were unhelpful. Perhaps somebody here can help me, this problem is killing my productivity. I would be glad for assistance of any kind. Thanks in advance.

This may solve your problem.

Various combinations were given to me by the help line, I tried theirs and yours. but no avail.

There were some of the first sites I checked, and the same steps were provided by bsnl, but they didn't work for me. I came across somone with a similar problem here.

(Exclude spaces please)

I would like to know where I can change this TCP MSS.

****************** = broad band forum . in

Again, pls exclude spaces.

To get TCP MSS Option, type 192.168.1.1 in your browser. Internet setting.

May be at advance > Nat settings.

Nope, NAT didn't have anything to do with TCP MSS, but all my NAT entries are disabled. Could that be the problem?

MTU/MSS/TTL etc are inter related.
Usually 1492 is the default MTU setting.
You can try TCP/IP optimizer from speed guide.net
and follow the recommendations.

Many Old modems do not have menu option to change MTU.

Para two : Summary of your Modem:
After you have entered all settings correctly
and rebooted the modem ( wait 2 or 3 minutes )
do you get Green Button against
Line 0_35 Bridged or PPPoE connection /
Do you get a "NOTE" icon also ?
If seen click it and again modem will restart.

Post these data :
Start RUN type cmd OK
New window
type ipconfig /all

My routers TCP MMS & TCP MTU values are on interface setup page. The default values are 0 (zero). I never changed those values. The router is working fine. No problem at all.

I have purchased a Macbook (OS 10.6) and want to connect the notebook to the BSNL Broadband through Wi-fi.. My modem is ITI DNA-A211-1.. Please guide me..

Thank you..

Please see link ( below) for WA3002-G4 for menu settings.
Hardware board is similar to DNA A211 -I
To set up wifi network with MAC OS ( I am on XP PRO SP3)
Check menu item for equivalent of Control Panel ( as in XP etc ).
