I am trying to reach websites that I was once able to reach. They now time out. 

It is very random, and Ive noticed at least 3 different ones.

These site work elsewhere. When I am at work they are fine, and when I have a friend try from his house, they work fine.

I have ruled out the devices - it happens on multiple devices connected to the router. Laptops, mobile devices...

I ruled out DNS - I changed it on the devices, as well as the router, then rebooted. No change.

I have reset the router to FACTORY DEFAULTS, and the issue persists.

IF I CONNECT DIRECTLY TO MY MODEM, THE PAGES DISPLAY.

I am noticing that others are having similar issues. This is definitely a problem with the router.

Please help. I was impressed with this router when I got it a few months ago - something happened recently that is no good.
