Linksys PLSK400 Powerline Internet Adapter Kit 200MBPS 1 Port + 4 Port 10/100 Homeplug AV

Comment:
I purchased this because I was having increasing problems with WiFi devices in my home theatre setup, in particular devices that only support 2.5Ghz. I can often 'see' as many as 6 other 2.5Ghz networks from neighbors and I have 6-10 WiFi devices in my home connected to the network at any given time. Just too much interference for reliable and consistent performance! :-(Before investing the time/money in a long CAT5 cable, drywall, paint, wall plates and switch to install proper Ethernet drop s in the basement I thought I would try this for the price of the cable alone.Installation was simple, take them out of the box, plug-in the two adapters, press the sync buttons...in under 2 minutes it is ready to use! I plugged my router into the single port adapter, and three home theatre devices (HTPC, AppleTV, BluRay) into the 4-port adapter (will be 4 when I get an Ethernet dongle for my Wii). No other network configuration needed, it just worked!Performance is reasonable and reliability is great! I consistently get between 30 and 32 Mbps (testing with file transfers between PC's over the powerline), faster than I could get 802.11N (2.5 or 5 Ghz) in the same locations of the house, and I have never had the connection drop  while using this PowerLine adapter. I have 25mbps cable internet, I typically get between 18 and 25mbps on SpeedTest.net. I get identical SpeedTest.net results over the powerline compared to connected directly to the router, perhaps a 1 or 2 ms difference in latency. I am achieving my objective of being able to take full advantage of my internet bandwidth from my Home Theatre using this powerline kit. Speed is not as fast as a 'real' Ethernet connection, transferring large files is relatively slow (max 32mbps), but it is fast enough for any media streaming that I have tried: Netflix 1080p, iTunes 1080p, YouTube 1080p, 24mbps 1080p MKV. Have yet to have a movie be interrupted by "buffering" since swapping to this powerline kit. My house is newer (built in 2001), but the basement is on a separate sub-panel from where my router located. I still had no problems getting this to work at the performance levels stated above.Having 4 ports on one end is a great feature of this kit, allowed me to plugin all my home theatre devices without having to invest in a separate switch. Removing 3 devices from WiFi in the basement seems to have improved reliability for other WiFi devices in the basement such as tablets. An unexpected benefit! :-)A great product! Performance will vary with quality/age of your homes wiring, but if you are having WiFi issues it is worth the couple minutes and small $'s to give it a try in your home. Don't expect CAT5 performance but if it does not provide better service than WiFi you can always take it back. ;-) My only regret is that I did not try PowerLine sooner.

Bought this device on sale for 49.99 + tax hooked it up not knowing if it would work in my house. Sure enough pushed the sync button on both of them and was online within seconds works wonders with my Dlink Router also.

The pros I listed were of a replacement unit after I did an RMA on it.My first one had extremely bad disconnection issues (approximately disconnects for 30sec every 30 minutes, even disconnected while talking to tech support once) which after going through Linksys tech support, allowed me to RMA the PLS unit in the package and get it replaced. Linksys tech support was really great in handling the problems, it was what came after that was hell.Their RMA offered me several options to replace the unit;1. They contact the store I got it from (NCIX) and switch the product there2. Regular replacement (I send defect back and upon receiving, they send me replacement) and3. Advance replacement (They send me replacement, and I send them back the defect when I receive it. A hold is placed on my credit card in case I don't send back.)I initially picked option 1, but according to Linksys, they couldn't contact NCIX, or NCIX wasn't returning calls, so I decided to go with option 3.I got the replacement, used it and everything was fine and dandy, no disconnects, so I packaged the defect and sent it back (with tracking number). A couple days later, I checked the tracking number, says it was received, thought everything done and over with.A little under a month after this, I see a charge on my credit card for $99 (cost they said to replace the unit). Confused, I called them, they said they never received the unit. Luckily I kept the receipt with my tracking number so I told them the tracking number and Linksys checked again, and said they received it and will be reimbursing my credit card in ~2 business days. That never happened.It's been about month and a half since they charged my credit card, and still no reimbursement, I've already called them a second time after waiting for my statement to see if the money would show up at my statement date. They said the same thing, they'll be reimbursing my credit card in ~2 business days and would be sending a confirmation email. I got a "confirmation phone call" a day later, but no email, and more importantly no money.TL;DR, great product if it isn't defective, Linksys RMA sucks.

I spent quite a while fighting with this unit, I thought it wasn't going to work for me and that the wiring in my building was one two circuits. It turns out that these don't work through powerbars (or maybe just surge protectors). After I plugged them directly into the wall outlets, they connected just fine.The prongs don't fit tightly into the wall outlet. So it's hard to get them to sit straight in an outlet. If they are behind your tv stand or under your couch this isn't an issue, but if they are somewhere visible (as is the case with my setup) it can take some work to make the adapter sit straight in the wall socket. And once you do, you'll curse aloud if you nudge it by mistake because it will sit at a 10º angle on your wall after doing so.Despite all this, this is a MUCH better solution for me than wireless. And since the initial install, I've had no issues whatsoever.
