[ILUG-BOM] Changing MTU values

I use reliance connection to access internet and their dialer too. I dont know why, but any other way fails to connect me to internet (like wvdial, kppp or pppd on command line).

I am able to connect to internet at a very slow speed as against that in windoz. Also, it shows a very low value of MTU (264). I tried to change it in /etc/ppp/options to "mtu 1500", but whenever I connect again, the values get vanished (gayab). How do I change the MTU values? Or get faster internet?

And one more thing, I always need to be root to run the reliance dialer (even switching to root is of no use) and changing permissions does no good. How do I make it run by a normal user (or even after su to root).
