WiFi interference. Solution?

Yes either I can get the WAP or a new router entirely but what would be better

Just a WAP. Simplest, cheapest, easiest, least overhead.

Same as if you had a need to connect three more wired devices in your front den, when you only had one single ethernet jack on the wall. What would you do? Could you use a second wired router to provide the additional wired ports? Yes. Could you use a switch to provide the same additional wired ports? Yes. Would they both work? Yes. Which would I suggest? The switch, no question.

In your case, you're trying to provide additional wireless capability to that location that can't get adequate signal from your primary wireless router at the other end of the house. That's exactly what a "wireless access point" was invented to solve... provide a few additional wired ports, and wireless capability, off of a single box that's kind of the equivalent of a wired/wireless switch. Would a second wired/wireless router accomplish the same thing? Yes. Do you need everything the second router would also provide? No. Would a WAP be sufficient to solve the problem? Yes. Which would I suggest? The WAP, no question.

You have your current primary Action Tech V1000h modem wired/wireless router installed by your phone company. There's very likely nothing you can change here, as that's the equipment they installed. It's a gigabit router. The only problem is getting wireless capability throughout your house, i.e. to the other end of your house where the V1000h won't reach wirelessly. You've already explained you don't have ethernet cable to that location.

So solve the problem easily with (1) one powerline adapter to deliver ethernet from your primary router through the power lines in your house instead of ethernet cable, to provide "ethernet over powerline" and deliver ethernet capability to a nearby AC wall adapter at the other end of the house, and then (2) WAP plugged into the remote powerline adapter end, to provide a second wireless network capability at the other end of the house, along with 3-4 wired ports as well should you want to use them.

Your wireless devices will be able to seamlessly connect to either your primary router's WiFi network, or to the WAP's second WiFi network. It will be exactly as if they were always connecting to the primary router as far as you're concerned.

Did you consider changing the channel? maybe a higher or lower channel will avoid the interference?
