If it happens at exact intervals (8 minutes), then your best bet is to try and find out what is happening every 8 minutes. Your router shouldn't be doing anything itself, but maybe it has some feature that does something on a timer. Or, you might have some program or some option in Windows that is occurring every 8 minutes and is conflicting with that router somehow.

If you haven't already, try setting up the router using the instructions on http://www.portforward.com/ . Although you shouldn't have to set anything up for mIRC in order to chat (only for sending files or using DCC Chat), it wouldn't hurt to try.

If you do figure out what is causing the problem, please post it here to give others more things to try if they have this error.
