I'm not convinced it is your config with the issue, but try adding the below. If it makes no differences take it back out again.
interface Dialer0
ip tcp adjust-mss 1400

Hello Sir,
Thank you very much for this line :)
It did help me :D
by the way can I increase it to 1460 or it other issues?
Thanks
03-10-2016 05:52 PM
Sure. If it causes a problem just lower it again.
I tend to go with 1400 these days as it pretty much works wit everything - and although 1460 is "technically" better - I defy you to produce any measurable difference.

Thank you very much sir.
I was having another issue with another website www. myjob. mu and i had to set another command along with
interface Dialer0
ip tcp adjust-mss 1400
it the MTU size
interface Dialer0
ip tcp adjust-mss 1400
ip mtu 1496
Everything working smooth now. :)
