Clearing cache on modem

[gotwind]

I'm having an issue with access to my website. I was told to clear cache and cookies on my browser. I did that, restarted, and still having the problem. I can get to it on my mobile device. It's only an issue accessing it on my desktop. Is it even possible to clear cache on the modem? Anyone have an suggestions?

There is nothing the like on a cable modem (or router).

On your desktop, try an alternate browser.

Might there be any "hacks" which redirected your own web site to a local LAN IP, e.g. in the hosts file?
