2 out of 5 eggsDidn't work for Ooma

Pros: works for pc connectivity

Cons: did not work for Ooma Telo

Manufacturer Response:

Hello Stevie Strings,

We are sorry to hear that you had an issue with using the TPL-401E and your Ooma device. The TPL-401E is a HomePlug® AV certified appliance and shouldn’t have had an issue. With a good PowerLine connection any network enabled appliance should be able to make a connection through them. At the location of the Ooma device please ensure that you do not connect the TPL-401E to a power strip or surge protector. This may cause connectivity issues. If you have a direct connection to a wall outlet and still have problems please email We can have someone assist you as soon as possible. Please include your contact information and a link to this review.

5 out of 5 eggsWorks fine for me

Pros: I bought this to replace my spotty wireless router. So far this thing works like a charm. I have not experienced any signal drops with it yet. It will have a speed drop if something gets plugged into the same line that pulls a lot of amps. For the price I paid for these on Newegg I will never go wireless again. I am running Windows 8.1 and haven't found any problems or conflicts with the drivers yet.

Cons: The only conn I have is that using this just for internet is kinda overkill. I will be setting up a home server net-work soon. I will update with after stress testing this unit.

4 out of 5 eggsTPL-401E

Pros: Worked right out the box, fast shipping from Newegg.

Cons: None so far

Other Thoughts: Some people mentioned do not hook it up to surge suppressor, I did off an extension cord. If it ever get warm enough here, I will hook it directly to the circuit box outside where I will use it. Might have to wait until the end of April :(

13 Mbps down, 13.5 up, Wifi was 27 & 22 on that laptop.

Pros: I initially just had one, but bought a second adapter later on sale. These work MUCH better than wireless.

5 out of 5 eggsWorks GREAT, want to get one more!

Pros: Plug them in, and they just work! I'm using one on the main floor, and one on the 3rd floor, and they work so much better than WiFi!

I purchased 2 because that was the limit during the "Shell Shocker" sale. I'm going to get a 3rd next time they go on sale.

Cons: None so far.
Just be aware that this model number is only a SINGLE unit, and you need 2 or more to talk to each other.

Other Thoughts: Ignore the other review comments about them not supporting TiVo or Samsung TVs, etc. because that's not true.

If you plug them in as soon as you get them (without any setup) they will work right away. But they won't see other devices on your network until you use the setup utility (which is very easy to use).
Simply copy the name of your network to these devices, with the setup utility and they'll work with everything else on your network. I didn't mess with passwords or encryption on mine, just changed the network name.

Remember to AVOID SURGE PROTECTORS, and plug these directly into the wall, as the surge protector circuitry will filter out the network signals, and they won't work well.

4 out of 5 eggsWorks well but order 2 of these, or a powerline kit, if you don't have an existing powerline setup in place.

Pros: I got this on a Shell Shocker for $20 expecting that I was getting an amazing deal for a powerline 'kit' with 2 units. What I got was a pretty good deal for one unit. As other reviewers have mentioned, make sure you get 2 of these if you don't already have existing powerline adapters on your network. I was able to get this one unit to easily work with my 2 Actiontec PWR500s. Now I have one PWR500 plugged into the router, one plugged into the desktop and the TPL-401E plugged into the Xbox. All in all I am glad that I don't have to buy another one at full price to get this unit to work.

Cons: Well it might be my fault for not double-checking the package contents before purchasing, but I really don't understand selling these individually - especially for $55 full price for one unit. You can get a decent kit with 2 units (maybe not 500mbps theoretical) for $40-50.

2 out of 5 eggsONE Adapter

Pros: I will let you know some day if this works. There is ONE, SINGLE adapter in this box. Why in the world would you sell ONE at a time? You can't do anything with ONE...

Cons: They sell them ONE at a time. Be sure to buy TWO if you want to network something.

Manufacturer Response:

Hello Rob,

I apologize for this one unit not meeting your needs. Yes, you are correct, the TPL-401E is just one adapter. If you would like to setup a network you can buy the kit which is TPL-401E2K , this would come with 2 adapters. If you have any questions you can let me know by emailing me directly at with “Newegg TPL-401E Review” in the subject line and I will be able to assist you immediately. I can also help with any of your product questions so your able to get up and running again. Thanks for taking the time to review our product. We hope to hear from you soon to regain your trust in TRENDnet.

Warm Regards,
TRENDnet Sales Support Team

2 out of 5 eggsTRENDnet powerline adapter

Pros: Works. If you change the default password, read the manual about syncing all the units. The house has whole house surge protection, units worked.

Cons: Bought a TPL-401E & TPL-405E, one or both failed within 3 months. Trying Trendnet for replacement.

Other Thoughts: Generally works well. Actually bought these to bypass the Alienware 17xr4 wireless card; which Alienware has said that it's my problem to resolve. The powerline ethernet worked fine in this case. (actually, faster than the dual band N).

I have noted times that the powerline units get glitchy if you pump a lot of data over these units for days to months.

If you install these to support hardware which talks to each other (Tivos, Samsung TVs, etc); the hardware on the powerline net will appear to be on it's own net. And may not appear on "other" nets, i.e. like an existing ethernet. If so you may need to put all the linkable hardware on the powerline net.

Unlikely they will work with other manufactureres equipment.

Manufacturer Response:

Hi Anonymous,

Our apologies for this powerline unit not working as promised. Please email me directly at with "Newegg TPL-401E/405E Review" in the subject line and I will respond to you immediately for a hassle free replacement of defective unit.

Warm Regards,

5 out of 5 eggsFantastic product. Works well for streaming.

Pros: Works very well, as advertised. (4) 1 gigabit ethernet ports are very useful if you have more than one device in a single room. These devices are Plug n' Go. They offer decent speeds to remote areas of a home or small office which would otherwise not have networking available. Lastly, they're pretty consistent as far as reliability and speed.

I would recommend these devices and even purchase them again.

Cons: Custom encryption can be a pain to setup. The Utility is a bit poorly designed, requiring WinPcap be installed to capture network data. Gigabit ports are great if you are networking 4 devices off of one adapter. Otherwise, it's kinda useless over powerline. Above I state that speeds are consistent and reliable. They are however they are far from the 500Mbps. Max speeds I've seen so far for the distance that my data is travelling is about 150 Mbps. It's a good solid 150 though.

Lastly, the lights on the device will change colors depending on speed drops, Green, Amber, and then either flashing or solid. This can be distracting in a media room if the device is in plain view. But it's not that big of a deal.

Other Thoughts: I've been skeptical about data traffic over powerlines because of EM interference. However, I am a recent convert and believer that this works well. I just moved into a new home and the networking layout was less then optimal. These devices now allow me to stream HD to my DVR which is literally across the house on two different floors.

I know that every review (including this one) takes note of speed and consistency which is contrary to the advertised packaging. You must take into consideration how 'clean' your home electrical system is and the distances which you are requiring from the adapters. They will perform "UP TO" 500 Mbps. But even at 150 Mbps, the adapters maintain the throughput for up to 500 Mbps per adapter. Do a search on throughput vs bandwidth and you'll understand what I'm saying here.

All in all, good purchase which I would do again and I recommend the devices highly.
