Log network drops

Is there way to list/log network disconnections on Win7?

I'm getting re-connected many times a day to interenet and it havent been happening just few weeks ago. So I want to have these drops listed so I can show them to my internet provider.

I would use either Performance Ping or , if you have access to a machine on their network, such as a SSH shell account, you might be able to use Java Net Perf to get much more detailed info.

Look for event ID = 27, source = your network card drive, e.g. for Intel gigabit ethernet, "e1yexpress". Just filter it and copy/paste.
