Dlink DIR-820L: How to Fix the WiFi Not Connecting Issue

 I have had several routers through the years, from a variety of manufacturers, including Belkin and Linksys.  Recently, my Linksys was acting up, and I was eager to upgrade to 802.11ac, the latest standard.  I found the Dlink DIR-820L on Amazon for the fair price of $69, and pulled the trigger.

The initial setup was simple, with the usual connection of ethernet wires.  The 820L has the standard plug for the internet from the modem, and then the 4 ethernet ports for wired connections- in my case I plug in directly a notebook, my Brother 2270DW laser printer as well as the adapter for a Powerline adapter (which is my backup network when the WiFi fails- more to come on this).  The 820L setup in about 10 minutes.  Based on something I had read elsewhere, I decided to name the new 820L as the same name as my previous router, and reuse the same password.  This move proved a seriously lousy idea, and I don't recommend it at all.

Intel Atom Processor Z3740

The Intel Atom processor series has been the weakling of the block; in other words, the chip that the other ones would push around the school yard. The Atom was born with the intention of an x86 processor that could work within a small power envelope, and keep the low power ARM chips from taking over the lower segment of the market. Intel originally envisioned their Atom chips in the gamut of low power devices, from tablets, to smartphones, and to long battery life laptops. The Atom did find some success in netbooks (N270), but many consumers got frustrated with the limited performance of a single core processor, and even when Atom went dual core (N550) it still offered only a minimal performance gain.
