Hello,

I have an unlimited 512kbps MTNL ADSL connection in New Delhi. Ever since I upgraded from 256 kbps to 512 my internet connection keeps dropping very frequently, many times when it is in the middle of loading a page, it'll just hang, then i'll reload the page and itll come up at regular speed. The thing is that this will happen every 20-30 seconds!
Basically this is the diagnostic test report:
>> Testing Ethernet LAN connection ... PASS
>> Testing ADSL Synchronization . PASS
>> Testing ATM OAM segment ping ... FAIL
>> Testing ATM OAM end to end ping ... FAIL
>> Ping Primary Domain Name Server . PASS
>> Ping Yahoo! ... PASS
So basically this is an ATM OAM issue. I have been hounding MTNL for 3 weeks and they are absolutely clueless, its quite comical seeing the lineman try to figure it out!

Oh, and after looking around for a solution I found one where someone advised changing the TCP MSS to 1360 bytes (from 0), so I did that and the issue did improve a bit, however the above diagnostic still keeps happening with both the ATM OAMs still failing and the connection still going idle, though a little less often.

Anyway, this issue is killing my productivity, someone please help!
Cheers,
Kabir
 
This is probably because your line cant take this speed. I am assuming that you dont have parallel connections ie: the tel wire should first come to your splitter/modem. Complain to 1504 or speak to your SDE (sub div eng) for your are area. Ask them to check your line. That should give the answer. Lazy sods rarely do it.
 
Recently i am also getting this ATM errors. My line stats are fine and no disconnection and ping issues but because of this ( i am assuming) my speed drops frequently i mean at one second it is at peak and other second at 7-8 kb/s. Websites sometimes also stutter and refuse to open unless i give a refresh command.
So far contacted on [email protected] but nothing happend.
PLEASE TELL ME WHAT ARE THESE ERRORS AND SHOULD I WORRY ABOUT THEM.

Don't know what this ATM OAM is
It fails for me too but my connection is working smooth
 
So what was the solution to this problem? In addition to these, I am also getting Ping Primary Domain Name Server - Fail
