fc5 midnight dropped connection

How I can prove whether it's either my isp or my system here that is dropping my network connection at midnight every night?

The connection isn't dropped at the exact same time every night, but between 00:04 and 00:08 I lose my connection.

I have a dedicated phone line for dialup access and have no broadband options for this location so interupted downloads are a royal pain.

dmesg and wvdial only choke out #16 and #10 error codes, but I don't know how to get any more detail.

More ideas are welcome.

if you have two computers you could try transferring a file or something large enough to go for ten minutes or so, and start it around midnight and see if it gets dropped.


connection, dialup
