[Tarquinius]

It's possible....I've had a modem overheat and burn out. IT may be too late to try and move it out of any dusty or confined areas..

But I'd look at the frequency of this. You said you only had this happening for 1 day. It might be there is line work being done, or that the bandwidth was shortened by extreme usage in your area. There are lots and lots of reasons that this could be happening, the only defining factor is how long it occurs for and how often...

Keep us posted! Hope all is well man
