I've used these for the last 10 years in my home. I have the Trendnet versions, and they work very well. The order of preference for a connection is to be directly wired via Cat6, then WiFi, then these adapters. The adapters work fine for most purposes. My speeds are pretty close to Wifi speeds. Previously in our other house, our router was centrally located in the house. I also have a Hackintosh that I can't get the Wifi to work, and there was no convenient way to run cable into my office. So these adapters came in pretty handy. My speeds were acceptable -- my uses for the network were just light internet usage, maybe some torrenting and uploading of YouTube videos. Nothing time critical, so the lower bandwidth was manageable. The wiring of our house was modern.
Currently in our new house, I am using these adapters to network my AppleTV with my Hackintosh, and then to a WiFi Range Extender in another part of the house. None of these require high bandwidth, and are fine for surfing, browsing on mobile devices and light gaming for my kids. Sometimes, maybe once every two months or less, the connection goes down, and I will have to unplug and replug the adapters.
I'm a big fan because they are inexpensive means to expand your network. However, if you need high bandwidth, I would probably invest in installing Ethernet cabling or get good wifi capability.
Anyone using one of these? The wife wants her Downstairs old corner PC workstation area cleaned out and return the room into it's original intended purpose...we are empty nester's...I'm thinking of turning my son's upstairs bedroom into a Bedroom/Music/Computer room (keep a Daybed-Trundel bed for holiday guests), but, house being built in the early 90's was not wired for such. I'll have my Digital Audio Workstation PC and 10TB NAS to hang out in the upstairs room...organize all the Taper equipment...my vast collection of Cassette Tapes of live music...host uTorrent uploads....etc. etc.
Will this thing work?
