You raise a good question! It was a long story as it happened, but in retrospect it may not have been as confusing of a problem as it seemed at the time.
I have U-Verse for Internet. AT&T, which promotes itself as a leader in telecommunications and technology, only offers modem/router units with Wireless G speed. Not N speed, the faster standard, or AC - the brand new option. No, they only offer G. Crazy. So I had a Cisco router connected to it so I could handle the WiFi in the house with more speed. I would routinely be watching Netflix or Amazon and get the dreaded "your connection has changed" message, and the picture would lose quality. Then it would gain quality. Then lose quality. Drove me bonkers.
So I tried a hardwired connection. That didn't help. That's when I decided it wasn't the speed that was the problem. I determined it was my router. Ultimately it came down to a fight over DHCP addresses. I reset the 192.168.1.1 home page for the AT&T router and picked a different IP, turned off DHCP and let the Cisco handle it - all sorts of scenarios you could think of.
Then I saw a review of the Skydog router on ZD-Net. It was touted as being a router that would let you subscribe to a service that let you adjust Internet speeds per user so you could turn off your kid's access at 9pm. (In practice, that isn't really as useful as it sounds, because the kid switches to Angry Birds - which doesn't need Internet.) But the article and the Amazon reviews said that the router setup would ask you which ISP you had and would automatically changes the settings on the modem/router so that the SkyDog would handle the IP addressing. I had already decided to purchase a new router anyway, so the universe was aligning just right and I pulled the trigger on it.
It worked exactly as described. The tech inside it is older, as I found out later, and it isn't the best one on the market. But any time someone came to my house with a Wifi device and tried to attach, I got a text message telling me about it. I no longer have streaming issues unless there is a real problem with U-Verse. All other things being equal, it has been a good router.
Now that they are no longer adding new features and doing constant firmware upgrades, then the router you listed may actually be a good choice for me. I appreciate you listing it! In hindsight it seems as if I could have done a hundred other things to fix it, but after visits to every big box store and any network-savvy friend I had without a resolution, it seemed to be the way to go. No regrets.
That being said - let the AC-compatible speed router shopping begin!
PS - as promised, I have started watching some of my digital offerings to see how they compare. My kid LOVES the iTunes Extra feature that shows all of the Frozen songs and skipping all of the 'boring parts' (i.e. the rest of the movie). For the 24 minutes it takes to go through the songs, he is literally Frozen in front of the tv! The quality is way better than I expected.
