Thanks a Ton man!

Even a very close friend mine just disconnected with Broadband connection just because of this.

Even after 2months BSNL guys were clue less about this problem:lol:

BSNL guys tried everything except this

Obviously none of the below things worked

  1. Changed his wiring

  2. Changed his Modem

  3. Told Format and reload OS on his PC, which he did

  4. The Reset the port from exchange

  5. The changed the port

Now lastly they said "Sorry sir, we don’t know what the problem is, we will ask the supervisor ".

byt months passed and no solution

He had no option other than to Terminate the service

Now, he would kill me if i tell him this simple solution:P

Reps added, Thanks

[edit]

I am also changing my MTU but there is problem.

I have changed MTU from modem interface(192.168.1.1) and from /etc/network/interfaces

but

ifconfig still shows it as 1500 :S

gaurish@Moody-Machine:~$ ifconfig

auto lo

iface lo inet loopback

iface eth0 inet static

netmask 255.255.255.0

gateway 192.168.1.1

mtu 1454

auto eth0

use the modem’s dialer, i think its the better option :slight_smile:

MTU is typically 1492

44

@gary: no baba!that is not the way.you start internet and then check ifconfig output for interface “ppp0”.

even better add “mtu 1454” to the file /etc/ppp/options .that will do.

if you are on dhcp(network) ,then setting MTU to 1454 for eth0 makes sense.

I Using PPPoE, not the bridge mode:|

purge network-manager and allies using synaptic. :expressionless:

Indeed, I was breaking my head quite a few weeks now, that just solved my problem :smiley:
