Hmm.. here comes the LCP monster again !!

Well this is getting more silly by the minute, I have known atleast five separate reports of this problem and they were solved in as many different ways!

There are a few things you can try Santosh, and see what works for you :-)

(1) Try connecting early in the morning like 8am if possible. In one case i saw,the problem NEVER occured before 9am and ALWAYS occured after 9am till late in the evening. If it works, the problem is with your ISP's response times (my guess)

(2) Recheck your modem config and serial config. Try dialling to a dialup number like 6246300 for VSNL through minicom and see if you get a prompt and are able to start a PPP session.

(3) Read through the ppp-HOWTO and try increasing the default values for the LCP timeouts themselves.

(4) Amazingly enough, at one site, the problem occured ONLY when dialing through Linux and not through Windows. This one was a configuration issue, so try through Winduhz if you can.

(5) Pray ;-)

Do tell us how it went....

In your case, I suspect it is a config problem.

Hope This Helps
