Powerline Issue: Picking up the wrong Router

[randomize4]

I am using a Sitecom 555 Powerline/Wifi extender off of a FRITZ!Box Fon WLAN 7360. Up until a few days ago it was working fine, then for some reason the powerline seems to have picked up another router. I can not access the internet, and every site comes up with a NetGear page that says that site has been blocked by the router and it only links backs to the NetGear site (which appears to be the only one not blocked). I can still access the Sitecom powerline, but I can not determine what settings to modify to get it to detect the desired router. I can provide images if that would be of assistance. To the best of my knowledge, there are no NetGear devices anywhere in the house.

The houses next to me are directly connected, so is it possible the powerline extender is picking up a different router? In general, is there any way to insure your powerline extender is connecting to the router you want it to?

Could be picking up another router....

Does the Sitecom 555 Powerline manual provide any information about reserving IPs for select MACs?

(Attempted to download manual - site would not let me do so for some reason)

However, I did get get the impression that there should be a security button that you push to establish a "private" network.

And then configure other devices accordingly to be on that network.

Did get this:

Homeplug
This product is a Homeplug AV power line device. Each Homeplug has a Homeplug network name. Multiple Homeplug devices with the same network names can communicate with one another, and thus belonging to a same Homeplug network security. Devices with a different network name won’t communicate.
Any ‘Homeplug-AV’ compliant Homeplug which comes new from the box, including this device, has a default network name of HomeplugAV. It can communicate with other brands of new Homeplug-AV compliant devices, thus these new devices are so called belonging to the public network. Pushing the SECURITY button of the device will change its network name. This way, users can create one or multiple private Homeplug network securitys using this button, without complicated setup software involved, thus protect their data which is being transmitted over the power line. Pressing the RESET button of a power-active Homeplug device will reset the network name back to its factory default (HomeplugAV).
By pushing the SECURITY button for more than 10 seconds, a random network name (different from HomeplugAV) for the device will be generated. This device can then ask other devices to join its Homeplug network to form a private network security. Any other device, the Slave Homeplug for instance, which wants to join this device’s (the Master)
Homeplug network security can be added by the steps below: (NOTE: it is more convenient to bring devices, which are to be configured into the same logical network security, side by side during this procedure. After the network security is set, the devices can be deployed anywhere at home)
Create a private encrypted network
Step 1: Create a secure network.
First clear the public network and create a private network on HomePlug A by pressing the SECURITY button more than 10 seconds until all LED lights simultaneously turn off and on once. Do the same on HomePlug B. At this moment, the network names have changed to a random name and are ready to be joined together.
Step 2: Join the secure network.
Press the SECURITY button of both HomePlugs for 2 to 3 sec (make sure the POWER LED starts blinking). It doesn’t matter which device’s button is pushed earlier than the other, but please push the second device’s Security button within two minutes after pushing the first device’s Security button. This way, HomePlug B joins the same encrypted network as HomePlug A.
Please note: If you want to connect with any of the below Sitecom Homeplugs, press the NMK button on these for 5~8 seconds to join a secure network.

Check your manual accordingly or go online if you do not have the manual. Hopefully the above will be enough to give you a start on the fix.

Unless your wiring is on the same circuit as another router, the far end of the power line (not the one on the router) can only possibly connect to the other powerline adapater that is in your house. As above, you can reset the security connections on the two power line adapters to pair them up again. It would be very very odd if your wiring was connected to your neighbors, that would mean your electric billing meter would be reading their power use or vice versa.
