Well, can I plug my powerline unit into a powerstrip anyway?

plug blue ray into separate different outlet ... plug all into powerstrip turn powerstrip off when not using

Basically, you unplug all of the Netgear Xe104 units, wait a minute, then plug the one nearest to the Router back into a wall socket first. Wait a few seconds then plug in a second Xe104 and give it a minute to "talk" to the first unit. Then plug other Xe104's in one at a time. Below you'll find the official troubleshooting steps which you should read carefully if the basic steps above do not resolve the problem.
Also, i should tell you that Powerline adapters such as yours have improved greatly in the last few years, and you can buy a pair of new ones that are very, very much faster than yours for a very modest cost. For example, TP-LINK TL-PA4010KIT
or NETGEAR Powerline 500 1-Port Starter Kit (XAVB5201) or
ZyXEL PLA4225 4-Port 500 Mbps Powerline Gigabit

Power Light Not On Make sure that, if power to the AC power outlet is controlled by a wall switch, the wall switch is in the on position. Verify that the wall socket is live by disconnecting the XE104 85 Mbps Wall-Plugged Ethernet Switch and plugging in some other electrical product, such as a lamp or a hairdryer. If the error persists and you have confirmed the power outlet you are using is live, you have a hardware problem and should contact technical support.
HomePlug Light Not On If the power light is on but the HomePlug light is not, check the following: • Make sure that power is being provided to more than one PowerLine device. Another PowerLine device must be installed for successful communication across the PowerLine. • Verify that the network password is the same on all devices in the PowerLine network.
Ethernet Light is Off • Make sure that the Ethernet cable is plugged in properly at both ends. • Be sure you are using the correct cable on the router that the first XE104 is connected to. When connecting the router's Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable. • On attached Ethernet device or network adapter card, check that the Link light is

If it is a GFI protected powerstrip then you likely have a ground fault issue, otherwise the powerstrip may be overloaded (unit should pull around 5 amps on startup) or faulty.

You need to plug the unit with 1 port into an outlet near the source of internet connection and the second unit acts as the hub once plugged in.

Try reset the device and start a new configuration.It seems that your networwork have issues between the router and the powerlines.All need to be in the same network as per router configuration.Connect one adapter to your router and plug it into an available electrical outlet. Plug the second adpter into an available wall outlet and connect the other end to any device with an available Ethernet port such as a gaming console, set-top box, or computer.

pd: OS to use the adapters; Windows 2000, XP or Vista.

Plug the PowerLine adapter into the wall
Plug one end of the ethernet cable into PowerLine wall adapter
Plug the other end of the ethernet cable into the Orange LiveBox
Plug the Orange LiveBox power adapter into the wall

The top speed between the devices is 14 Mb/s, so they will never attain the 20Mb/s speed you had with you router / modem.

• Powerline products work better when plugged into the wall without power strips, extension cords, surge protectors, or uninterruptable power supplies.

• Passwords. Powerline products have both a network password, and a device password. A particular device's password, which is not changable, is printed on the Powerline product label. Once you have collected all your Powerline device passwords, use the encryption dialog box, as described on pages 9 and 12 of the XE102 User's Guide, to change the network password. (Without password protection, it is possible, although unlikely, for someone very nearby to access your network.)

• If you changed the default network password, make sure that all the Powerline products use the same network password.

• If you've moved a Powerline unit, or disconnected the cables, your other network devices may need about 5 minutes to refresh their information about the Powerline's current status.

• If you have earlier Powerline products, switch to the encryption used by later products. (Early versions of XA601 and XE602 are known to have compatibility problems with newer models.)

• To test whether a house's electrical wiring is contributing to Powerline problems, plug units in the same room. Examples of potential problems are:
  
  • Old fuse boxes.
  • Old wiring that does not meet modern wiring building codes.

• Swap devices to isolate the problem to a particular Powerline unit.
• Reset the Powerline adapters to the default settings using the utility.

• Use all the same Powerline models for best connectivity. Also, software for one model may not work for another model. In particular, remote and advanced features may not work between Powerline manufacturers.

• Powerline is not directed at businesses, however it may work in a business environment, anyhow. See Assessing Powerline for Business Environments. In some cases noise can be limited by placing line conditioners or surge protectors between the source of the noise, and the Powerline units. (Not between the units.) Consult a professional electrician to evaluate your electricity's noise and to suggest remedies.

Hello. I can help you. Let me review some info. about microwaves.

First of all, a microwave requires a lot of power. Most microwaves must have their own circuit to work well for a long time. Do not use any powerstrip or other extension cord, always plug a microwave directly into the wall.

The problems you are having are most likely due to your powerstrip than to your home wiring.

Plug your microwave directly into the wall and use it. If it works then discard the powerstrip as it is a fire hazard. get back and let me know how u make out.

No; the Powerline products have a built-in surge protector. Plug the unit directly into the wall socket.
