Hi

I am the proud owner of a shiny new USB GSM modem. It works a treat for a bit of surfing and email, and I have been using it to good effect with my Lucid setup.

However, I left it plugged in and connected last night, with the intention that it should stay connected while I slept. Imagine my disappointment to find that it seemed to have disconnected itself after about 3 hours! I unplugged and re-inserted, and all was working again this morning.

Is this something Ubuntu has done to try to help me? Or maybe a 'feature' of the network? Is there a way of debugging or monitoring why it disconnected?

Thanks in advance!
Charlie
