Howdy! I currently have frontier fiber, and they had me move my router from the living room to the office. I now have deadzones in my back yard thanks to the fireplace, as well as my security cameras in the front yard sometimes go out. My router is the rt-ax86u. I’m looking at getting a second router, and doing wired backhaul. Do you guys have suggestions on what the second router should be? Do I need another rt-ax86u? Or should I be looking at something cheaper? Thanks guys! I’m new btw!
