IRC disconnected after 2hrs, 2mins.

I'm using mIRC 6.16 with Sysreset, connected to Rizon, which has been fine for months, with no problems whatsoever.
For the past week, I've been disconnected every 2 hours and 2 minutes on the dot. It's always a Software Caused Connection Abort.
Any ideas?

I had the same problem a year ago but i can't remember how i fixed it. I think it was the router, i'm not sure

I forgot to mention, my housemate is also connected (via the same router and also using Sysreset) and doesn't have any problems at all.

Yeah, I had the same problem too and it was the router. Is it a Dlink? Try changing the *something* timeout.

Use Sysreset then.
