I've recently tried upgrading my home network kit. I have a three storey house and a garage out the back of the garden - and like to use WiFi everywhere. I bought a few of these:
TP Link TL-WPA281KIT AV200 Powerline
I have three of these wireless access points. The performance over the power wiring is great - if I test one of them on their own or plug in an ethernet cable into them - its very fast (speed tests get 10Mbps - which is the speed of my ADSL). I've given all three the same SID and WPA password. I've put them on non-overlapping channels (1,6 & 13) and they're spaced out across the house/garage. So the intention is that my devices can 'roam' seamlessly as we go around the house.
HOWEVER, the WiFi performance is quite bad. Most of our devices (iphone, Android phone, laptops, media player etc..) are getting intermittent signals and poor performance. Its especially a problem when in the parts of the house where you can get a signal from one or more of the access points. If I'm in a part of the garage where you can't get a signal from the two in the house, performance is great too. In addition, I've just turned off two of them and have only one switched on. And performance is great in the part of the house with most problems before that. No intermittent connection and very fast.
So, I can only conclude that these three access points are interfering with each other? But they're on non-overlapping wifi channels? How could this be possible?
I'm really stumped and very frustrated that I've made my WiFi network worse despite spending a couple of hundred quid on kit! I've spent an hour searching forums - but the only thing I keep seeing is that this should work in theory as long as you use non-overlapping channels? Any suggestions or ideas would really be appreicated?
