Issues with Access Points Over Powerline

Hi there,

Allow me to describe my current home network setup, then I will detail the problems I am having. My modem is located in the basement of a two story home, so the wireless router is also located in the basement. Since the wireless does not sufficiently reach the 2nd story, a powerline adapter set sends wired network to a desktop computer upstairs. I recently added two powerline wifi access points to this setup - one upstairs and one in a dead spot on the main floor. To summarize, 4 total adapters on the network - 2 of which are access points. Each access point is configured to have the same SSID as the primary router, same WPA2 password, each on a different channel. The primary router assigns IP's from 192.168.1.4 - 254 and each access point was assigned a static IP of 192.168.1.2 and 3 (with DHCP turned off).

The problem I am running into is the wireless clients (mostly android devices - windows not so much) seem to either loose internet connectivity intermittently, or frequently drop the connection altogether and reconnect again. Though the deadspots in the home have been eliminated, the actual network reliability has plummeted since adding additional access points. However when connected and working, network performance/speed has been excellent.

Is this a problem with my setup or my access point configuration? I know powerline networking is not the best solution, but hard-wiring is not an option. My suspicion is that there is some sort of bottleneck from trying to funnel multiple connections through a single powerline adapter to the main router, and I could potentially remedy this bus setting up two separate powerline networks and having each one with a separate LAN port on the router.

Any help would be greatly appreciated!
 
The issue is that with a single set of powerline adapters, you were better off than with the additional units. Sometimes multiple powerline adapters don't work together. Are they all the same standard, keyed with the same password, or are they 2 separate networks?

Depending on your coverage needs, I would likely take the 2 new powerline/wifi devices off the network, and up with the desktop plug in an access point. This should be less buggy.

Android devices in general are picky about connecting.
 
I would try to set the SSID to different values so you can control which AP they connect to. What happens is the device can move between the AP which is a good thing in some ways. The problem is powerline devices take much longer than your normal switch to figure out the mac address has moved from one powerline device to the other. It does this on physical switches also but it normally can figure it out in a tiny fraction of a second. There was some discussion of reducing this timer in the powerline standards but I don't know if they took any action.

At this time, they are all on the same network and keyed with the same password. Would having two separate powerline networks be better or worse? I have also considered adding a gigabit powerline AV2 (new standard) adapter as the basement adapter, as they support MIMO and might help.

If this is a limitation of powerline networking, I will just remove the access points. I have had no luck with wireless repeaters, so I will need to look for another solution to some of the dead spots in my home.

I have witnessed both. The most common occurrence (which typically occurs while watching YouTube/Netflix) is that the devices just drop internet access, and I must turn off Wifi and reconnect before it works again. I have also seen where the device will keep saying "Connected to Wireless Network [SSID Name]" which indicates that it has just disconnected and reconnected quickly. I had assumed this was a handoff from one access point to another, but it happens while stationary.
