Modem Hangup

[anitha2324]

I have installed Fedora 6 core in my laptop (Qosmio Toshiba) , i have set up the Adsl connection (using Speedtouch 585 ethernet modem ) ,

i got successfully connected to the internet ,

after 2 days of getting successful connection to the internet , suddenly i was unable to get connection to the internet

#pppoe-start

............................Timed out


i have checked the log messages and i found the following

#cat /var/log/messages
....
modem hangup
timeout waiting for PADO Packet
......


by the way i have tried to use the modem in another pc and i found that there is no problem in the modem


i have formatted my laptop and install fedora core 6 again in my laptop and i have successfully set up the adsl internet connection , but the same thing happened , after working for 1 or 2 days i got the same error "Modem hangup"


Please do help me to solve this problem am a newbie to Fedora linux

According to this page:
http://www.linuxsa.org.au/pipermail/linuxsa/2005-April/078835.html
The problem could be caused by a feature of your service provider that limits how fast you can reconnect or ignores you because it thinks you might already be connected. The page says you can test this theory by using the command line to temporarily change the MAC address of your interface. (This is not something I have tried myself.)

is there any suggestions ?????

A question that occurs to me is whether there were any updates (manually or automatically) after your new installations? They might have changed something.

My interpretation of the error messages is that there is a problem with pppd and this causes the failure of pppoe. So my only suggestion is to look for web links on how to debug pppd problems. There used to some rather elaborate web pages on using ppp and dial-up modems, but my searching today didn't find them. Perhaps dial-up is too obsolete. The debug approaches on those old pages were to use a terminal program like kermit to start ppp manually and observer all the transactions.

The page http://pptpclient.sourceforge.net/howto-diagnosis.phtml#debug has interesting information but I don't know if it applies to your problem. Google has many hits for: "LCP: timeout sending Config-Requests"
