TRENDnet 200 Mbps Powerline AV Wireless N Access Point TPL-310AP (White) Review

TRENDnet 200 Mbps Powerline AV Wireless N Access Point TPL-310AP (White)
Average Reviews:

If you want to use the advanced features of the AP, the documentation is very light. The average user would be lost. My AP is installed about 85 feet from the Powerline Ethernet connect to the router and the maximum speed is only of the wireless is only 60mb and has a red light indicating good connection. I only get a green light, best connection, when the AP is less than 25 feet. I suspect the problem is that the circuit the AP is on is located on the opposite side of the buss in the power pannel then the Powerline Ethernet is connected to.

ZyXEL NBG-318S 200 Mbps Powerline HomePlug AV 802.11g Wireless Router Review

UPDATE 1/2011
Both replacement units have failed in their HomePlugAV modules, so I have no HomePlug connectivity. In fact, scanning for Homeplug devices from the managment UI causes both units to crash. Downgrade to one star.
-------------------------------------------------------------------------------------------------
UPDATE 7/2010
My 2nd unit has failed as well; it began spontaneously rebooting and wouldn't stay working for more than a few minutes at a time. However, I got pretty good service from ZyXel: they replaced BOTH units under warranty. Still working 11/2010.
-------------------------------------------------------------------------------------------------
UPDATE 5/2010 :
I reduced the rating to 2 stars after one of my two units quit working after about a year. The Powerline connectivity evaporated after about 9 months and the wifi connectivity started to get intermittent after a year or so. Now the unit will only boot sporadically.
-------------------------------------------------------------------------------------------------
I bought this unit to set up a Homeplug network connection to a home entertainment system that's poorly located for Wifi access, and after some fiddling I'm getting very good performance out of it, nearly 40Mb/sec in real-world circumstances.
When I ordered this router for thirty-nine bucks, it was much cheaper and more capable than the ZyXEL PLA-401 200 Mbps Powerline HomePlug AV Wall-plug Adapter that it's intended to be used with- so I bought two NBG-318S's instead, and configured the 2nd one as an access point. That gave me the benefit of having a 4-port switch as well as a Wifi extender in the access point - why buy the PLA-401? (It's still listed a comparable price.)
Wireless strength was comparable with the D-Link WBR-3210 that it replaced. The router's in the basement and I still have decent signal quality two floors up in our wood-framed house. Plus having the 2nd router configured as a Wifi access point using Zyxel's "roaming" mode (Wifi clients are seamlessly handed off between the two radios as they migrate around the house) has effectively extended our Wifi coverage.
Be forewarned: it takes some arcane BPL voodoo to achieve maximum Homeplug network bandwidth across your A/C circuits, even if it is brand-new shiny code-compliant wiring like at our house. I spent an afternoon juggling the topology of outlets and power strips amongst my appliances while running iperf() between my client and server to monitor the network throughput. I don't think there's any way around the trial and error approach if you want to get good performance out of these things. By some simple, free (but time-consuming) rearrangements of the router, access point and appliance connections the bandwidth at my desired location went from 1Mb/S to 40Mb/S. Here are some tips:
* Homeplug AV performance can be good, but don't believe the 200Mb numbers the vendors throw around; I couldn't even get that bandwidth when the router and access point were plugged into the same outlet next to each other and connected to gigabit Ethernet clients.
* New adopters should be aware that the router and its access points can be on different circuits but pretty much need to be on the same 110V leg of your 220V house service to work. You'll have to check your circuit breaker panel to figure this out for sure.
* The Homeplug network's signal quality (and hence the achievable bandwidth) is extremely sensitive to noisy appliances plugged into the same circuit. For instance, at one point my bandwidth went from 25Mb to 8Mb when I plugged Apple's spiky Powerbook A/C adapter into the same outlet as the access point, and I still take a 5Mb/S hit if someone turns on the dimmable incandescents in our office. I may try putting ferrite chokes on the supply lines of some flourescent fixtures that are still on the common circuits.
* Having the access point plugged into an outlet wired closer to the breaker panel didn't necessarily help. I'm getting the best performance with the access point plugged into a different outlet than the home entertainment appliances, but further in wiring distance from the router - go figure.
* I thought that using surge-protected RF/EMI-filtered power strips on my appliances would help keep noise off the power lines carrying the network signal, but if the noise-filtering power strips were plugged in too close to the access point they actually seemed to filter out the network signal and my bandwidth dropped. Also, some power strip's LED indicators actually put more noisy spikes BACK INTO the line and made the throughput worse; after I quieted them down by clipping out the LEDs, the noise filtering seemed to have some positive effect.
* The Homeplug modems appear to use adaptive signal processing to operate in noisy home environments - the bandwidth can take a big hit when noisy appliances are initially introduced onto the circuit, but then you will see it slowly improve over 30 sec to a minute. (In my experience it was best to reboot the access point in the presence of the noisiest possible signals.) So let your bandwidth measurements settle down before making an evaluation of the benefits of a change to your topology.
* Find a software utility that will allow you to accurately measure data throughput on your network while you are making changes. You'll be chasing your tail if you try to use subjective evaluations of, for instance, how long it seems to take to load a web page. (You'll typically be looking for better LAN performance than your WAN's internet bandwidth anyway.) I used the the iperf utility (Google for it) available for MacOS, Windows and Unix-type systems.
I got good - if not super-prompt - feedback from a customer service technician in response to my prepurchase questions when sent through ZyXel's web site, but haven't heard back from my latest query by regular email. I'm also giving only 4 out of 5 stars because the latest manual available from ZyXel STILL doesn't mention features that are clearly available in the router's standard web-based configuration interface (their Windoze-based configuration "wizard" never functioned properly for me under Parallels) and it took me an hour to figure out how to enable simple WEP wireless security (hint: make sure WPS is turned OFF.)

D-Link DHP-W306AV PowerLine AV Wireless N Extender, HomePlug AV, 11n Review

D-Link DHP-W306AV PowerLine AV Wireless N Extender, HomePlug AV, 11n
Average Reviews:

Didn't work, sent it back (thanks, Amazon).
I plugged it into an electrical outlet in the room next door, no connection (green "house" light not on). Tried in my office next to the router, still nothing, a flickering green house indicator. This is with the new DHP 1320 router, which works fine. I was on the support line for an hour, no luck (OK support). I plugged it directly into the router and could get to the IP address but no connection still. I gave up and returned it rather than spend my weekend fighting with a network.I'm waiting for more reviews to see if I was doing anything wrong. My guess would be that the DHP 1320 router is not broadcasting through the powerlines properly.

Linksys PLTK300 PowerLine Network Kit Review

Linksys PLTK300 PowerLine Network Kit
Average Reviews:

(More customer reviews)
My wi-fi experiences a problem in a certain part of the house. I had tried different routers including 'N' and the signal would randomly and frequently drop in this one area. I installed the PowerLine in under 30 minutes. The two computers connected have not experienced any outages ever since. Don't forget NOT to plug either unit into a power strip or APS. It will only work if the plugs are directly into the wall socket.

The Linksys Powerline Network Kit contains a single-port Powerline Adapter, and a four-port Powerline Adapter, which let you easily create a network using the existing electrical outlets in your home. Now you don't have to drill holes in walls and climb through the attic or cellar to install network cables -- just use the wires that already run through the building.With Powerline Network Adapters, you can connect computers or any other wired Ethernet device using the HomePlug 1.0 with Turbo network standard. They also work with older HomePlug 1.0 devices. Adding devices to the network is as simple as plugging a Powerline Adapter into an electrical outlet, and connecting your Ethernet-equipped devices to the built-in Ethernet ports. Additional devices can be connected to the same network using additional Powerline Adapters plugged into any electrical outlet anywhere in the house.

Innoband HomePlug AV Wireless N Starter Kit Review

Innoband HomePlug AV Wireless N Starter Kit
Average Reviews:

(More customer reviews)
The Good: Bridges Ethernet devices and extends Wi-Fi coverage using *existing power lines*. Performance is exceptional.
The Bad: Setup is less than straightforward. Documentation is limited.
The Ugly: The 210P-I1 access point's antenna is poorly designed and fragile.
I purchased this product because Wi-Fi reception in my kitchen (which has a lot of stainless steel cabinets and is far away from our Linksys WRT54G Wireless-G Router) is poor.
Before setting up the Innoband HomePlug Kit, laptop reception in the kitchen was bad but tolerable. However, a Logitech Squeezebox Duet Wi-Fi Internet Radio we purchased recently was unusable. We had to walk out of the kitchen to use the Squeezebox Controller, and the Receiver in the kitchen simply couldn't keep up with the streaming audio. Synching with our older Squeezebox was impossible because both players would cut out for seconds at a time.
When I purchased the HomePlug Kit, I was worried that ethernet over power lines simply wouldn't work or would perform so poorly that it wouldn't be useful. I was also concerned that the 210P-I1 access point would be annoying to configure or incompatible with my 802.11g devices. Finally, I was taking a chance by buying an unreviewed product from a company that I didn't recognize.
But the HomePlug Kit does just what it is advertised to do. Namely, it bridges Ethernet devices and extends wireless coverage over existing power lines. And it does so with exceptional performance--better, it feels like, than my existing wireless network. In fact, after the 210P-I1 access point had been running for a few minutes, all 5 of the devices that had been using my router's Wi-Fi selected the 210P-I1--automatically.
My one major complaint about the HomePlug Kit is the 210P-I1 access point's fragile antenna, which I managed to snap within moments of removing the device from its packaging. The break is only cosmetic (the wiring is intact even though its housing was comepletely separated from the unit) so I decided to use some super glue rather than go through the hassle of a return. But I hope Innoband will address this design flaw in future revisions of the product.
My second, lesser complaint is that although Innoband effectively promises a plug-and-play configuration, the experience is in truth less straightforward. The main issue I found is that the 210P-I1 access point was not configured to work with my home network (it was using a different subnet and wireless network). Which isn't really that surprising, but I had to exercise some trial-and-error in order to get everything configured as desired.
In order to integrate the 210P-I1 with my home network, I had to:
1. Connect my laptop via the supplied Ethernet cable to the 210P-I1.
2. Configure my laptop for the same subnet as the 210P-I1:
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.210
3. Connect a web browser to http://192.168.1.210.
4. Reconfigure the 210P-I1 with an IP address on my home network.
A. Click "Lan Setting" [sic]
B. Enter an IP address from my home network (e.g., 192.168.0.NNN for addresses ranging from 192.168.0.0 to 192.168.0.255)*
C. Click "Apply"
* Your specific configuration may vary.
5. Reconfigure my laptop for my home network's subnet. Generally this just means using DHCP, but you can use a static configuration like:
IP Address: 192.168.0.NNN
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.XXX
6. Connect a web browser to http://192.168.0.NNN (i.e., the IP address configured in step #4).
7. Reconfigure the 210P-I1's SSID to match my router's existing SSID.
A. Click "Wireless Settings"
B. Change "Network Name(SSID)" [sic] from "innoband" to "mywifi".
C. Click "Apply"
8. Ensure that my router's wireless channel and the 210P-I1's do *not* overlap.
A. Channels 1, 6, and 11 do not overlap
B. The 210P-I1 access point is already configured to use channel 6
C. I reconfigured my router to use channel 11
9. Ensure that my router uses the same encryption and secret as the 210P-I1.
A. Click "Wireless Settings"
B. Click "Security"
C. Choose the "Security Mode" (WEP or WAP) that matches my router's
D. Enter the WEP key or WAP pass phrase that matches my router's
E. Click "Apply"
Admittedly that's a lot of configuration (and the documentation doesn't cover it adequately), but in the end the Innoband HomePlug Kit does exactly what I need it to do. Which is more than I can say for a lot of products I come across.
I plan on ordering another 200P-I1 (the wired device) to bridge more A/V devices like the Samsung BD-P1600 1080p Blu-ray Disc Player.
p.s., Innoband included a black knit watch cap with the HomePlug Kit they sent me. This was a nice gesture (and not a bad cap either).

Siemens HOMEPLUG/POWERLINE MINI ( 936-2521-001 ) Review

Siemens HOMEPLUG/POWERLINE MINI ( 936-2521-001 )
Average Reviews:

(More customer reviews)
I purchased the Siemens 2521, 2501 and 2502 Powerline adapters and connected them to the outlets in my home, (which is less than five years old). The setup was easy but the included instruction guide stated little more than "plug it in".
The problems began when I installed the included configuration software on my three computers equipped with WINDOWS ME and discovered that the utility program either froze Windows or took close to 2 minutes to start. The SpeedStream Support staff is aware of the problem and told me that "the programmers at Efficient Networks are working on it".
But the biggest issue I have is that none of the three Powerline products will stay connected for more than 10 minutes! I have tried changing outlets and even tried hooking up the adapters at my friend's house but these things simply refuse to maintain a connection.
Bottom line: Unless you enjoy loosing your network connection and having to get up and reset adapters every ten minutes, stay away from Siemens Powerline products...at least for now.
