Well, since fiddling around a lot with my router & cfosspeed, I've managed to stay connected.

Thanks anyway everyone.

No, and nothing is overheating.

I'm not using wireless, I don't leave the bitcoin client open while I mine and all of my temperatures are completely average.

Really? That must have passed me by somehow.

I'll keep an eye out for it though!

And that will affect guiminer how?

On full load my 6870 doesn't go past 66C with the fan set to auto (non-user defined), if you have filters on your case fans they could be clogged up (that's happened to me in the past) and you may also want to research the airflow of your case to see if it's effective or not.

*shrug*

I'm not mining with a laptop and temperatures aren't an issue. I can still connect to my router, but it is noticably slower. My ISP haven't had any problems during these outages so I think it really is just my router being clogged up with connections, what I really need is a way to limit the connections it makes 

blargh.

This was happening while I was using a limp little 4770, now that I have a 6870 I'd prefer it to stop happening at all 

Bump.

So I've been mining for a couple of months now, not doing too badly either, but one problem I keep encountering every few days is a total loss of my internet connection, it usually happens during the early hours while I'm asleep so I don't find out until the next day. I'm pretty sure it's because of guiminer as closing it seems to fix my internet connection... so uh, any ideas why this would be happening?
