So, first off you should know, that I'm a novice when it comes to internet and home networking technologies.
I'm an AT&T customer and I have what I believe to be a 2Wire 2701HG-B Gateway DSL router modem. We had some other router before that which died on us and we replaced it with this one. At that point, I believe we only had 1 desktop computer.
Currently, we have a desktop, a laptop, an Ipad, and at least 4 Iphones connected to this one router at any given time. I've noticed that our Wi-Fi has been slowing down and I assume it is because of the increased workload. I'm also assuming that, the router is only meant to handle 2 devices at most.
I'm thinking of getting a second Ipad and a PS4, that I'd like to connect to our Wi-Fi network. I assume I need to buy another router to accommodate these other devices.
Am I correct in assuming this? If so, what should I look for in a router. I believe the current range on the router is good enough.
Thank you all in advance for your time.
Added (1). I don't want to call AT&T because I don't want to be limited to only the modems they have available.
