Ethernet over Power Powerline Converter- HDStream Kit + Integrated WIFI 200mbps

Why spend hundreds of dollars and untold hours of your life running Ethernet cable throughout your home, configuring routers, and all the other things you need to do to setup a home network? Simply plug these Ethernet Over Power Powerline Converters from Monoprice into your home's power outlets and you've got a high-speed network all ready to go!

This HDStream Kit includes two Wireless N Powerline Access Points (AP). When plugged into the same electric circuit and paired, the APs can transmit Ethernet data signals over the electrical wiring at speeds up to 200Mbps to distances up to 300 meters! The APs are fully compatible with the HomePlug AV standard, which means that they can be used in conjunction with other HomePlug AV compliant devices, even those from other manufacturers.

By default the adapters will automatically pair with each other in an unencrypted public network called HomePlugAV. Using the built-in web-based utility, the network settings can be changed to provide data encryption on a private network. Each PowerLine network can support up to 9 PowerLine devices, though any number of PowerLine networks can co-exist on the same electric circuit. The network can be grown organically, starting with a single HDStream Kit and adding additional PowerLine adapters as needed.

In addition to wired connectivity using the RJ45 LAN port, these PowerLine Converters support Wireless N networking with speeds up to 300Mbps. They support the standard suite of security protocols and options (WEP, WPA, WPA2, 128-bit AES, etc) as well as MAC-based Wireless Access Control. Quality of Service (QoS) settings allow you to prioritize bandwidth to devices or applications that have the greatest needs, such as prioritizing bandwidth for video streaming applications. The mandatory WPS function allows you to quickly and effortlessly establish wireless connections between the PowerLine network and WPS-enabled clients.

Simply put, home networking can't get any easier than this!

did not work with 9920 adapters

Pros: work as advertised but not compatible monoprice 9920

Cons: documentation minimal and poorly written

I have been happy using the 9920 (they can be temperamental linking but once working they work well) powerline adapters, which appear to be the same thing without the WiFi. My hope was to keep one without wifi at my router and have wifi at the far end. The 9921 do link and with each other but not the 9920s. They are listed as using the same powerline standard and the (minimal) documentation even shows a picture of the 9920s. I tried and tried but no luck. I plan to send them back

*MUST* set computer to manual IP 192.168.0.XX to properly set up

  • Anonymous,

Pros: pair easily
good throughput
communicate across sub-panels and disparate circuits

Cons: default open Wi-Fi network re-configuring is a bear due to poor documentation
*MUST* set computer to manual IP 192.168.0.XX to properly configure Wi-Fi
Monoprice reps don't know product to support wanted to RMA due to lack of know-how
included "manual" (tiny pamphlet, 6-pt. type) is rubbish
MUST download actual, in-depth manual included mini-disc is useless to most people

*MUST* set computer to manual IP 192.168.0.XX to properly configure... you won't find PLCs on your network to configure them unless you do this absolutely important step!! units come with default IP address of and you need to access them via web browser to re-configure to your network and close Wi-Fi network.

these are great, and a good value, but they default to an OPEN Wi-Fi network and re-configuring them is a bear due to extremely poor documentation and zero product know-how from Monoprice reps.

save yourself some headache and read the how-to from reviewer Coopr on the first or second page of product reviews.

I am truly sorry to hear about the trouble experienced when setting up PID 9921. If I may ask, did you speak with us via phone, chat, or email? If over chat or email, what was the email address used when filling out the pre-survey? Please let me know as we will be looking into this further. My apologies again for any inconvenience and thank you in advance.

hi Gabby.
i did a live chat, and the rep was very friendly and professional. seeing that i'm not the first purchaser/reviewer to run into these issues, i think Monoprice should just revise its documentation and instructions for this product.

by Monoprice Administrator
I completely understand and do apologize for this experience. I will submit a suggestion for revised documentation to be taken into consideration. Thank you very much for your time and feedback - we truly appreciate it! If there is anything else that I can assist you with, please don't hesitate to let me know.

A relative bargain

Pros: Quality feel, paired up immediately and worked great

Cons: Only "high-level" documentation, so troubleshooting can be a problem if you aren't pretty techie.

Second set I've bought and have been pleased with their performance, but setting them up took awhile - security configuration.

Good idea, but worked poorly for me

  • Ted B,

Pros: Low cost implementation of Ethernet over Power Line. I appreciate it has a built in WiFi AP on both sides.

Cons: Multiple problems with reliability and basic functionality / wish it obtained an IP from DHCP instead of / includes a mini CD with a manual that is unusable in the vast majority of computers.

I really wanted this to work, but unfortunately I had a very poor experience. For context, I am a network engineer and very technical. I wanted this as a simple way to extend my WiFi network. I did get it to work initially, by plugging in the two nodes on opposite sides of my house. But, a speed test showed only 2-4 Mbps, whereas my Internet connection is 50 Mbps (fiber to the home). On the admin page for the adapter, it showed ~30 Mbps between the adapters, and the one side was plugged into a switch port on my router, so not sure what's up with that. I have also had it drop its connection after working for a couple hours, resulting in very low Wife Acceptance Factor.

I also didn't really understand the security implications of configuring the device with or without a "network password".

The mini CD that's included isn't usable in any computer I have touched in the past 7-8 years. Wish the manual, etc. were downloadable from like other products.

I'll give this a shot again after hard resetting both devices, and maybe with a different WiFi router, but it's likely this will get returned for a refund.

Thank you for your review on PID 9921. My apologies for the inconvenient experience you have faced while using this converter so far. If I may ask, can you describe to me your setup including all devices that are currently connected to the adapters as well as the length and types of Cat cables (5, 5e, or 6) in use? Just to verify, are the adapters being used on a surge protector or any adapters or are they connected directly to the power outlets? Also, are there any high power consumption devices on that circuit? If possible, can we test the adapters in the same room?

I also wanted to note that I can send out the manual to you if you would like. I would just need the best email address to send that to. Please let me know and thank you in advance!

Careful of switching power supplies on same AC leg as powerline network

  • Anonymous,
  •  San Francisco, CA

Pros: Works well, good coverage, fairly easy to set up if you have networking experience

Cons: terrible printed instructions. Incomplete in some places, dead wrong in others, printed in something like 6pt font.

Overall, I'm happy with this system, but I almost sent them back due to some undocumented strangeness that I had to overcome.

things of note:

-Use the instructions you find in the reviews rather than the printed ones included in the package. The manual on the mini CD is much better than the printed quick start guide, but not as succinct as the ones you'll find here.

-The power line network seems to be sensitive to some noisy switchmode power supplies being plugged into the same leg of AC as the adapters.
I had a stable network going for a week, then plugged my (cheap asus) laptop into the same power strip as one of the adapters and lost the network. I thought I had to solve the issue by hard resetting both adapters, but the next week when this happened, I saw the home icon turn off as soon as that power supply was plugged into the same strip as the adapter.
I also had an issue with an international-voltage battery charger being plugged into the same leg of AC. The outlet was in a different room, but was on the same leg of AC. I've solved the issue by plugging in these noisy supplies after my UPS instead of before it, where the adapter is. An AC line noise filter might help, and an isolation transformer certainly would.

- some reviews complain of how hot the units run. Note well there are three plastic anti-scratch covers on each unit: one over the top and two on the sides. The pair on the sides cover the vent holes! I noticed the adapters ran far too hot until I saw/ removed the side covers. Proper ventilation allows the units to run at a reasonable temperature.
