Random wireless ping spikes, changing hardware results in no performance change

I have been having random ping spikes ever since we switched to atnt over a year ago. I know this issue has been covered to death but I'm hoping someone or a couple people can help me trouble shoot. some details:
I currently have an Asus ac66u router with an Asus ac68 adapter. I had the ac66 adapter but it did not work with my motherboard and Asus got me the new version when it came out.
I bought both items because I thought that the AC might help with possible interference issues.

Before that I had a Belkin router and a d link wireless adapter. I have the exact same issues with both sets of hardware so I'm guessing for now that it is not hardware related. If it is hardware related it would most likely be something to do with the modem. More likely than that however I would think (not that I would know) that it is a windows setting (just did a fresh install, same issue) or the internet provider.

I'm sure sure what is the best place to start.

Testing ping for google got back a ping average of around 28ms however once in a great while there would be sudden pings of 98, 150 or 200. The vast majority of the time however it pings around 28ms.

Testing ping for my modem had pings all over the place. They started out around 30ms and kept jumping form 10 to 200ms. They eventually settled down to 1 to 2ms. Running the test again almost all the pings were around 1 to 2ms (immediately afterwards).

Testing ping for my router returned the vast majority of pings 1-3ms while once every 30 seconds or so it would ping at 7ms or 15ms.

Also of note is that we have ATnT and as such we have an ATnT wireless router as well as the asus. They are pretty much right next to each other. Unfortunately other members of my residence have claimed they will not run cable hard wired to their receiver. To minimize the interference I turned the ATnT wireless signal to the lowest possible db strength.

So right now with all this in mind I think interference may have a small bit to play in the issue but that the biggest issue is either the service or the modem.

Last bit of information for now, this happens on AC and on an N connection.

I apologize for all the random bits of information but I am just trying to put everything out there that I can think of at the moment.

How would you guys go about solving the issue?

Thanks in advance

You should really turn the ATnT wifi off, are they within 3ft of each other, try to separate them and use channels 1, 6, 11. Can you run wires for you stuff / move the Asus to you room?

Are they connected together or different isp accounts?

The channels are as far apart as possible. Neither the Asus or the ATnT router can move unfortunately. What is also unfortunate is that the router is as far away as possible from my room. I still get 4-5 bars with wireless N, and 2 bars with AC although the AC is still faster.
