Netgear PE102 10MBPS(10BASE-T) Home Phoneline RJ11 Ethernet RJ45 Bridge Review

Netgear PE102 10MBPS(10BASE-T) Home Phoneline RJ11 Ethernet RJ45 Bridge

The marketing literature claims that the Netgear PE-102 "seamlessly extends your high-speed Internet connection, or your existing Ethernet network ...". Seamless is definitely in the eye of the beholder -- especially where networking is concerned -- but in this case, I have to agree.
I installed the PE-102 to replace a PC that I used as a bridge between my phoneline and ethernet networks. The PC worked fine as as bridge, but needed to be on whenever someone wanted to use the internet from a machine on the phoneline network. The PE-102 not only solved this problem, but also freed a slot in the former bridge machine, since I no longer needed both ethernet and phoneline cards installed. The PE-102 also uses a lot less power than the PC I used for a bridge.
Installation was quick and straightforward. Both phoneline connections are clearly marked (to wall, to phone) and the unit includes only one ethernet connection (RJ-45 10/100 Mbps, auto-switching). There's no software to install or to configure. The product includes a fold-out installation guide that suggests possible network configurations and provides technical specifications for the unit. I was operational within 5 minutes.
The PE-102 has performed flawlessly from the moment I hooked it up. All machines (whether connected by ethernet cable or phoneline) now appear to be part of the same network -- whether the machine is running Windoze or Unix. Throughput is excellent, even when several users share the same internet connection via ethernet cable and phoneline. So what's not to like? Here are a few things I found less than perfect: (1) cable connections are on the front of the unit, rather than on the rear. This makes for a somewhat messy appearance in a home/SOHO environment. (2) cost -- the PE-102 seems expensive by comparison to other network components. This device is a "digital adapter" that integrates ethernet and phoneline networks. It's not a router or a switch or a firewall. It doesn't do sophisticated encryption or on-the-fly data compression or web-content filtering or anything else beyond what it claims to do -- connect ethernet and phoneline networks. (3) the installation guide fails to mention that the PE-102 can share a phoneline connection with a computer: just connect the PE-102 to the phone jack in the wall, and the computer to the "to phone" connection on the PE-102. Now the PE-102 and the computer are both connected to the phoneline network. Similarly, I suspect the PE-102 could be used as an internet gateway for phoneline networks (but without firewall protection or content filtering), even though the installation guide does not mention this possibility.
However, these are pretty much minor annoyances. There's plenty to like about the PE-102, including solid construction (metal case, not plastic), 5-year warranty (1 year on power adapter), and reliable performance. This is a product that does what it claims to do, first time, every time, right out of the box. Although I didn't need it, I've found Netgear technical support to be both competent and responsive -- and one of the few organizations willing even to talk to you if you mention the word "Unix" (or "Linux"). You won't find that among the product features listed on the box -- but it's included, nonetheless.
Recommended.

Belkin Wireless Play Max Router (F7D4301) Review

Belkin Wireless Play Max Router (F7D4301)
Average Reviews:

(More customer reviews)
My experience with this router has been one major mistake after another. I didn't check the Amazon reviews before purchasing - my mistake. I bought it (not through Amazon) - my mistake. I threw away the packaging after setting it up and now I can't return - major mistake.
Although this thing was simple enough to set-up, it has been a major letdown for all of the reasons that other reviewers have mentioned. I've had it for 2 weeks now, and I count it a good day if I only have to reset the damn thing once. My devices all run more slowly than on my old router, and the stupid thing freezes up constantly. I've also run into multiple IP address conflict messages and have to reset it to prevent those messages as well.
I'm so frustrated that I'll likely trash the pile of junk and go buy another brand. Shame on me for buying this thing - and shame on me for not keeping the packaging until I knew how it worked (or didn't in this case).

Westell DSL Modem Review

This DSL modem is a piece of junk. Not exactly sure what the problem with this thing is, but it has to be cold booted (unplug it, wait 15 seconds, plug it in again) every morning if I want to retain the through-put I'm paying for.
If you own one of these things you can see for yourself how bad it is by running a speed test at the DSL Reports website before doing a cold boot and after doing a cold boot. In my case the download speed *DOUBLES* after a reboot.

I bought it to try and rescue data and pictures from an old broken nokia phone. It did not work as described by the manufacturer. The instructions clearly state that a "free" software download is needed from the nokia website. This is where I explain (outdated). Almost all new laptops have some sort of wireless technology such as WiFi or bluetooth, So do nokia phones, this is how you can connect to the computer a free downloadable software. If for whatever reason you need a cable then by all means this is the product for you.

RJ45 1x2 Ethernet Connector Splitter, Light Beige Review

RJ45 1x2 Ethernet Connector Splitter, Light Beige
Average Reviews:

(More customer reviews)
This device allows you to COMBINE 2 ethernet ports from a switch/hub/router into 1 cable and to SPLIT the cable back out to 2 ports for use with computers or other ethernet devices.
A typical ethernet CAT5 cable has 8 wires in it; and for 10/100 ethernet networks you only use 4 of those 8 wires. Therefore you can use the other unused 4 wires to run another ethernet segment.
In order to use this product properly you have to connect 2 ports from your switch/hub/router. Then a regular CAT5 ethernet cable to wherever you need to go and put ANOTHER one of these on the end to split the signal back out.
Typical use:
PROBLEM: You have 1 ethernet cable connecting to a computer (for example) and you need to add another computer or other device. You do not want to run another ethernet cable.
SOLUTION: Install one of these on both sides of the ethernet cable. 1) At the source of your ethernet network (where your router/switch/hub is); remove the existing ethernet cable; then take two empty ports and plug them into the 2 ports side of this device. Then plug the ethernet cable that you just unplugged into the single port side of this device. 2) At the end where the computer is, remove the ethernet cable from the computer; and plug it into the single port side of this device. Then connect your computer and the additional device to the two port side of this device.
(It does not matter which port of this device you plug your computer/additional device into).
In closing ... You MUST combine 2 ethernet ports from your switch to make this work. I see reviews all the time from people who do not know how this works and they give bad reviews because it won't work for them.

USB to Serial RS-232 DB9 Adapter Cable Review

USB to Serial RS-232 DB9 Adapter Cable
Average Reviews:

(More customer reviews)
This adaptor is considerably cheaper than many on the market but works perfectly well. It appears robust and well made as well as simple to use.
I've not used any other adaptors so don't know if this is universally true but the thing that I liked most about this adaptor is how simple they've made the software that ships with the device. There is no fancy front end bloat ware, just a simple set of drivers on a CD.
Although, the installation is easy if you have a small ammount of knowledge about PCs, it wouldn't have hurt to put a note on the box for the benefit of less tech savy users of how to find the instructions. There are no paper instructions with the product but there are instructions hidden on the CD. Open it up in explorer and look in the directory with the same name as the product. The instructions are good and show how to install in straight forward pictures of exactly what to click on.
Using Windows XP, Just insert the CD, plug the adaptor into a USB port and wait for the 'found new hardware' wizard to start. All the settings are standard and your PC will know where to find the drivers. After you've installed it, you may need to know the COM number of your new port. You can open the hardware manager, that's in right-click 'My computer' - properties - Hardware - 'Device Manager'. Look in the 'ports' sub menu and you'll see the new port with it's COM number. Any software that connects to a serial device will need to know the COM number to work. The other way to find out is to just try ports 1,2,3,... untill the software for your PDA or whatever manages to connect. I know that sounds complicated but I've spelled it out in great detail, it's really fairly intuitive.
In short, before you junk that old programmable remote control or PDA because your new laptop doesn't have a serial port, use this, it's cheap and it works.

Cables to Go 37133 2-Port RJ45 Splitter/Combiner Cable, Gray 6-Inch (Single Unit*) Review

Cables to Go 37133 2-Port RJ45 Splitter/Combiner Cable, Gray 6-Inch (Single Unit*)

I'm thinking the people rating this poorly don't understand how to use it. It WON'T split a single Ethernet CONNECTION into two. It WILL enable a single Ethernet CABLE (which has 8 wires) to carry two connections (which require 4 wires each). This is helpful in places where you have a single cable running from your router (typically in a wiring closet) to two devices, and can't easily run a second cable -- i.e., where one cable is already installed in the walls.
Here's how you use it: Run Ethernet cables from 2 ports of your router into the female jacks of the first splitter. Plug the male end of that splitter into the jack in your wiring closet that runs to the part of your house you want. Plug the male end of the second splitter into the Ethernet jack at the other end of that cable run (i.e., in the room where the devices are located). Run Ethernet cables from the female jacks of the second splitter to the devices.
If you want to use a single Ethernet connection for two devices, these splitters won't work; you need a router that shares the connection among the devices.
