Hi.
On May 2 my ISP replaced the DIR-827 with the same model.
We have configured the new DIR-827 just to act as an access point and left all the router functionality to the ONT router, the technician told me that the cooling pad was no loner needed, but I left it anyway, because I noticed that the new DIR-827 was a bit hot.
What is strange is that this cooling pad throws few air, but with the old DIR-827 it was not cooling properly, or perhaps the old DIR-827 was hotter?
This new DIR-827 with the same cooling pad is very cool

Since May 2 until today, my Internet and WiFi are working fine

All the weekend I tested it by using Netflix, and also downloaded several files, and everything is ok.
I've even notice that my WiFi is more stable with less speed variations.
So I guess that my old DIR-827 was also defective.
Hope things stay ok.
Thanks
