Dual-Band Router Issues

Hello,
About 4-6 months ago I moved from my previous house-(located in a subdivision within town) to a new "trailer home" located quite a ways out from town. I moved in and setup my router with no issue! It worked like a charm. Fast forward about 6 months later; the darn thing won't work! I called my ISP's and they said it's because the router is a dual band router and will not work with their services. But the thing is it was working for such a long time with no issues! I still would love to use this nice router out here but if there is nothing I can do I guess I must invest in a mediocre router.

The problem I'm having is the WAN light is lit a pink color. If I unplug the cord from modem it turns a deep RED.


Please if anyone can help, it would be much obliged.
Thank You

I didn't find the right solution from the Internet.
