Summary: Works great in a homogeneous network, so it is unknown if it will play well with others. The hard-coded passwords for making some changes is difficult when devices get installed in "out of the way" places, so make sure you keep tabs on them before you install them. The configuration utility is not very friendly on high DPI devices.
Summary: I have been using a wireless connection for over a year in my bedroom on the third floor of my house. My wireless modem was on the second floor and on the other side, about 40 feet away at a diagonal. Upgrading the wireless router and the adapter in my computer weren't exactly an option, neither was running 100 feet of RJ45 cable through the walls.
Pros: Faster download and upload speed than wireless, no housing maintenance, was inexpensive on sale.
Cons: Higher PING, short cables, can't plug into power bar.
Excerpt: Hige improvement over my wireless network in the house. Worked great to wire up my office and living room from the router. But when I tried it in the bedroom, at night I noticed a little high pitched noise coming from the device. It's not loud, but I found it annoying, so I unplugged it in the bedroom at night.
Summary: Purchased these on sale; excellent value compared to other Powerline adapters. Features and construction quality are good considering the price point. Performance is reasonable (but I'm only need it to max out my 10 Mbps internet connection). Sometimes, I need to cycle the power once a day to restore internet access to my PC, but this is not a consistent pattern and I can't be sure it is the Powerline adapter.
Summary: I use this to extend my network to areas of the house with a very weak wifi signal and avoid the use of long cables. Currently I have 2 sets of these and another set of an older model (TPL-401E). Six total. One will be used to receive the network signal to transmit to the rest. Set up is fairly straight forward. Just plug and play. Otherwise, if you want to set up a more secure network, you can install the utility that comes in the box and set up your network from there.
Pros: *Compact design, *Easy to set up (sometimes needs a little tinkering), *Minor degradation of speed - at least as good, if not better than wifi (802.11n capped at 300mbps)
Cons: *When powered down, sometimes goes out of sync, *Decreased performance if plugged into a socket with other electronics, *Terrible connection if using on old power outlets
Summary: Fairly easy to use. Benn using it for awhile with no apparent problems. Have had some difficulty logging on using a computer but the setup seems to work flawlessly. Takes a little time for it to recognize the network and range seems to be good. Went from 3 bars to 5 bars sitting in my living room through several walls.
Summary: These are basically plug and play. I would have liked the utility software to work with the devices without having to plug them directly into my PC. I had a problem when they went to sleep, but the firmware update fixed that issue. The speed is good if you can plug them into the same circuit side of the breaker box (outlets on the same circuit). These solve my problem, but the speed is similar to wifi.
