M1 light on DI-704P router flashing...

Yo,

I found that the M1 light on my d-link router is flashing, and I don't remember it doing that! I bought it quite a while ago though... maybe last year. I have had some small problems with it recently... My "good computer" can do anything... But my old computer on the other hand has trouble pinging the gateway, and even my good computer. I disconnected everything, resetted my router the "real way" and let my router cool down without any power source for about an hour. I even downgraded my firmware beucase it seemed to have happened not long after I upgraded to version 2.75...

Anyone know what this can mean? Or what the M1 light means in general? In the machines I'm used to working with though, flashing is either an error message or a "process indicator".

Because of this I can't test dumb things like remotely shutting down Windows XP with home made programs while my brother is hogging the computer playing stupid games!!!

Thanks.
