I'm trying to set up my wireless network with a powerline extender. The extender itself is a wireless access point. - it is this model.

The main internet modem/router is downstairs, it is connected to the powerline adaptor at the mains, and the extender is plugged in upstairs.

If I use the standard out-the-box setup then it creates a whole new unsecured network upstairs. This isn't what I'm after as it means my devices are all swapping and changing between networks whenever they can see both access points. (Sure, I can make it a secure network, but it's still a separate network that gets picked up by any device in the house along with detecting the main router) What I'm looking to happen is for the extender upstairs to just be an extension of the main network - the same network, only with greater coverage.

So, my next attempt was to get into the properties of the extender and change the SSID to be the same as the main router, and also to use the same security key. However on setting this up it takes down the actual internet access in the whole house 'limited or no connectivity' until I unplug the extender upstairs.

So it looks like my two options are:

a) have two separate networks in my house and have my devices swap and change whenever they detect one of the two access points (which is annoying as it means I lose connections whenever I move around the house and the device I'm using decides to connect to the other network instead).

b) have the extender using the same SSID as the main router but not have any internet access (which is even worse).

As far as I can make out the best option is to disable the DHCP on the extender access point - but there is no DHCP options at all to do this.

What am I missing here? How can I extend my network around the house with the equipment I have? Have I just bought the wrong equipment? Is the DHCP taken care of elsewhere - on the main internet router? Am I missing some other settings?

when you say takes down Internet for whole house is that wireless and wired connections or just wireless? might be that the channels are the same on both extender and router meaning that they conflict with each other –  James Jun 24 '13 at 17:03
    
Good question about wired / wireless, I'm not sure so I'll check that out however checking the channels being used with inSSIDer had them both on separate channels. Also, the extender picks up the best channel automatically so shouldn't need to be altered. –  JonW Jun 24 '13 at 18:28

ok. usual setup would be to assign a static IP to the extender from main router and then only have dhcp on one of the two. I answered another question a long time ago with a bit more detail here superuser.com/a/289389/74620 –  James Jun 24 '13 at 18:44

I have done something similar using 2 wireless access points connected using a wireless signal instead of a signal through the electricity. link to instructions/diagrams

The main idea of what you are trying to do is the same. The extender you have upstairs needs to be placed in bridged mode. Do you see this setting in the configuration page?

That does sound like I need different equipment than that which I have though. I'm hoping to get it sorted with this powerline extender as I already have that to hand. –  JonW Jun 24 '13 at 18:29
    
You are correct. The example is showing what I did using different equipment. However, the general idea is the same. You need to place the extender that is upstairs into bridged mode. Is that an option you see available in the configuration page. –  Gilbert Jun 27 '13 at 19:39
