Hi, I read your post and I have a couple of questions. Fyi, I’m an IT specializing in networking and telecom. (That’s just so you know where my questions are stemming from)
What kind of router is your main device?
What kind of internet connection do you use?
What are your internet speeds when tested by ookla?
What type of AP’s, are you using?
And lately, do you know this…
The typical AP I’d not a very good device for exceeding your range. In an effort to keep the price point less than a router, the AP has very poor band filtering. Because if this, the average AP cuts your signal speed in half. Ie; your 60 mbs signal is reduced to 30 mbs when connected through that device. This is not widely known, our realized as the average person never notices.
This is what I do and what I have in my home.
Main router is an Asus dual band as86 (I think). This is a multi antenna very powerful router. It sits as close to the physical center of the house as possible and on the second floor.
My AP is actually an old sysco single band router. I’ve sideload a firm ware on it to make it a fully customizable AP that disables the router capability. The device acts as a wireless AP that repeats at full power. It allows for wired and wireless connections to it and connects wirelessly to my router. This device was replaced by the main router.
This device sits on the second floor almost directly beneath my main router. I have my ST hub wired to this device.
This setup covers a 2400 sqft 2 story house. I have three teenagers with Xboxes, computers, phones, and tablets, plus my wireless tv’s and about 50 other things on my networks.
With everything going and streaming, nothing glitches, ever. Talking about speeds and streaming content.
Ok, to the point of this. One of your problems may be the AP devices you have in your setup.
There are a lot of factors that can degrade your between.
How old is your house?
What are the walls made of? Sheetrock, wood, plaster, all of the above?
How old is your router?
How old is your modem?
I upgrade my router every 3-4 years with a modem upgrade every 2 years.
The hardware is out of date and the speed differences is incredible.
Sorry fur the long read, but I might be able to give you some pointers to help improve things.
