Yes we had the same problem and spent hours trying to fix my device when it was actually the router. Our internet providers did not acknowledge that there was a problem with the TP Link router until another customer had the same issues. Our internet service providers found a 'Fix' for it online. Sorry I do not know what the fix is. I am looking online now as suddenly, pictures and websites aren't loading properly like before and I have to keep repairing the connection.

I would suggest you replace the router, it can't be coincidence that this thread keeps popping up with the exactly same model #.

And the same suggestion from March applies, with this many issues with this PARTICULAR model router, I would suggest replacing it or working with the router manufacturer on resolving it.
