After my Linksys WRT54G failed, I was not looking forward to another wireless router installation 'experience'. It took the better part of one day to install the Linksys with the aid of multiple downloaded documents from their web site to finally get the right combination to work. The Linksys was still in warranty when it failed, but no amount of money or service would convince me to continue using this unit. I was tired of having to reconfigure it about once a month when it would just decide to quit working.
So, thanks to high ratings for the Zyxel X-550 router on Amazon.com, I thought I would go this route. I am not a real technical writer so I am not going to get into the comptuer buzz words that the geeks will use (I do not understand what they say anyway). I do not care how it works, as long as it works and is easy to install.
Well, I followed the basic installation instructions and it was working within minutes. I use a Bellsouth provided DSL modem and there was absolutely not one single hang up to get on-line in just a few minutes. Setting up the security encryption was just about as easy.
I have used the Zyxel X-550 for several months now without a hiccup. I have two, and sometimes three, different brands of wireless access points connected most of the time without any problems. I did add a Zyxel directional antenna to one unit which was in a bad location.
The Zyxel X-550 is easy to configure and is now basically one of those items I just ignore and forget about because it just does its job day in and day out and needs no attention.

Synopsis of Brief Ownership:
* Package arrived on time and well packed by DBRoth.
* Supplied CD did not install the 8187 Realtek driver. Had to plug in the adapter and let Win XP find it to install the driver. Procedure had to be used on 2 different computers.
* This is a B/G unit only and does not incorporate N like Alfa's B/G/N unit. I've been informed that particular unit (-nt5) does not perform as well. Perhaps having to deal with 3 different protocols, something was given up. Also, the -nt5 model is really not a 2000mw device since 1000mw is the FCC legal limit. The -nt5 model allows momentary bursts of energy, but not for continuous connection. I'll leave that to the RF or Realtek experts to comment on.
* Placed unit both inside and outside of both first and second story windows. The unit easily doubled to tripled the available APs.
* Marginal signals, 1 to 2 bars, jumped to the max of 5 bars.
* The great signal quality may be attributable to no antenna cable attenuation loss since both the adapter and antenna are internally embedded along with power supplied by dual USB connections.
* For outdoor use, the user will have to seal against the elements better than the Alfa design. While adequate, the USB connection is susceptible to the effects of the elements. In a marine environment, I recommend sealing the interior USB connection with liquid electrical tape or a corrosion inhibitor and sealing the access panel with silicone or sail tape to prevent water intrusion.
* Caveat: The user must keep in mind that while this unit dramatically improves the ability to reach out and touch, it is also important to know that the other end must be able to handshake as well which impacts ability to retain a solid connection.
So far, so good.

Cisco-Linksys WRT300N Wireless-N Broadband Router Review

Cisco-Linksys WRT300N Wireless-N Broadband Router
Average Reviews:

(More customer reviews)
The WRT300N works flawlessly "out of the box" in wired configuration. It does not work at all "out of the box" in wireless mode.
Now, having made that harsh statement as if it would apply to every user in every case, some qualification is certainly in order.
I unpacked the router and took extreme care to follow the setup instructions PRECISELY.
I was connected to the internet the second I finished running the configuration utility from the installation CD - but the catch is that the setup utility has to be run with an ethernet cable connected.
Once I removed the cable and tried to connect to the internet in wireless mode - the end of the line had arrived. There was no connection. Period.
I could connect to the router via its built in config (HTTP) utility and I could ping the default gateway (in the router) but I could not get past that point.
After a couple of hours of fruitless trial and error, I gave up and called Linksys tech support. You know what that means - you get to talk to a person who knows next to nothing about computers or routers. But, they do have their scripts to follow and if you are patient with them and endure the mindless, mostly just plain useless instructions they give you and don't offend them, they will eventually let you talk to a Tier Two person who actually does know something about routers.
To end a very long story with a quick summation, after reaching the aforementioned Tier Two person, I learned that there are arcane, obscure settings buried deep within the router's config menus that you will never find without help (and even if you did find them by accident, there is no chance you would know what to do with them). After changing 5 of those settings, the wireless functionality magically worked and I was connected.
The router is fast. My cable provider only grants me 8 megabit service and the router handles that with ease - wireless or wired.
This would be a 4 or 5 star appliance if it arrived on your desktop with working settings. I doubt that anyone who is not a Linksys or Cisco Systems engineer will actually be able to get it to work in wireless mode without a call to Linksys tech support - unless those units manufactured more recently than mine (April 2006) are shipped with valid settings.
Normal users can stop reading here, but for those who are interested in the technical details, here is a summary of the settings I had to modify in order to get the thing to work:
Router web admin page - Applications & Gaming - QOS - Enable "WMM" and Enable "No Acknowledgement" (the factory default settings are "Not Enabled")
Router Admin Page - Wireless - Advanced Wireless Settings - "Fragmentation Threshold" was changed to 2304. "RTS Threshold" was also changed to 2304. The "Beacon Interval" was reduced to 50 from its factory default value of 100.
Here are a couple of sincere questions for you. Even if you are a "Power User" would it have occurred to you to check your Beacon, RTS and WMM settings, among others, when you realized that you did not have wireless connectivity? If you say "yes," would you really have known WHAT settings to replace the defaults with?
Other than that, it's a really nice router.
**Update 5/21/06**
After using the router for a few days now, I have some follow-up comments to make. Several times a day my laptop will "lose" its IP assignment from the router. Right-clicking the wireless connection in the systray and electing to "repair" the connection restores the IP address, but that is a real bother and it should not be necessary. This never happened with the wireless router I replaced with the WRT300N. I suspect Linksys will be releasing a series of firmware updates for this model until they finally get all the "quirks" (let's not call them bugs) worked out.

The Wireless-N Broadband Router is really three devices in one box. First, theres the WirelessAccess Point, which lets you connect to the network without wires. Theres also a built-in 4-portfull-duplex 10/100 Switch to connect your wired-Ethernet devices together. Finally, the Routerfunction ties it all together and lets your whole network share a high-speed cable or DSL Internetconnection.With Wireless-N, the farther away you are, the more speed advantage you get. It works great withstandard Wireless-G and -B equipment, but when both ends of the wireless link are Wireless-N,the router can increase the throughput even more by using twice as much radio band, yieldingspeeds up to 12 times as fast as standard Wireless-G. But unlike other speed-enhancedtechnologies, Wireless-N can dynamically enable this double-speed mode for Wireless-N devices,while still connecting to other wireless devices at their respective fastest speeds.

We use one of these for tradeshows to connect multiple computers at the booth and can share the connection with our colleagues in other booths. When the wife and I travel, we can be on the internet on separate laptops. If a client is without internet for whatever reason, this can serve them for a short time days until they are back online.
It's easy to setup and with the firmware update never drops the connection to Sprint.

Subject to customer authorization by Linksys.The Linksys Wireless-G Router for Mobile Broadband is really three devices in one box. First, theres the Wireless Access Point, which lets you connect both screaming fast Wireless-G (802.11g at 54Mbps) and Wireless-B (802.11b at 11Mbps) devices to the network. Second, it is a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Connect four PCs directly or attach more hubs and switches to create as big a network as you need. Thirdly, the Router function ties it all together and lets your whole network share a mobile broadband Internet connection (requires a mobile broadband data card). Alternatively, you can also connect a cable or DSL modem to the Ethernet port and access the Internet via your available broadband service. Once your computers are connected to the Router and the Internet, they can communicate with each other too, sharing document files, a printer, storage space, and other resources.

Cisco-Linksys WMP54GS Wireless-G PCI Card with SpeedBooster Review

Cisco-Linksys WMP54GS Wireless-G PCI Card with SpeedBooster
Average Reviews:

(More customer reviews)
The good? Wireless speeds are in excess of the 802.11g spec, so I am getting 100-110Mbps (12.5-13.5 MBps) from the basement to the living room easily. Once the initial horror of setup was over, I've been happily connected ever since. And you can't beat the price: Linksys gear is dropping in price, likely due to a ramp-up of pre-N gear on the horizon. (That's the new 802.11n standard which promises 6x the g-rate, and pre-N Belkin gear is delivering triple the speeds, so 150Mbps, or nearly 19 MBps).
The bad? Customer support, or lack thereof. I had a problem with the client not seeing the router. The *real* problem was the firewall on the basement machine. However, mention the words "Workgroup" or "file and printer sharing" to a Live Chat Specialist and watch how fast they come back with "we don't support configuring Windows" and a link to a knowledgebase article that will not give you a step-by-step diagnostic.
That's a shame, because a troubleshooting map would come in real handy. I fixed the problem myself -- I usually do with rare exception -- but for the non-IT professional, I fear for you. It's Belkin or Netgear for me next time.
And even more: the DHCP server on these routers are apparently very flaky. I could never get mine to give up an IP address to my WMP54GS card, so in the ened I configured it for a static IP and was connected. Woe to the inexperienced customer who tries to get an IP from one of these automatically. This issue is known throughout the Internet, but good luck trying to get Linksys to admit the problem and fix it.
The ugly? Try installing it. IF you manage to see your router on the first shot, your karma is perfect and heaven awaits you. Sinners like myself are forced to install the Linksys drivers only after the failed promise of Wireless Zero Configuration fails. Yes, you'll be switching between the Windows config and Linksys config a few times until you get it right. My suggestion would be to ensure you can see the router first (channel selection being the biggest 'gotcha' here), then worry about encryption and such.
Also, don't be surprised if the DHCP server on the WRT54GS router doesn't give you an IP address. It's a known issue to the outside world, which is waiting for Linksys to admit it and fix it. Configuring your WMP54GS with a static IP will get you fully connected in every case.
I have companion reviews for the WRT54GS and WUSB11, also Linksys gear. They won't be very flattering, either, but it's XMas time, and readers should not be giving bad gifts.

This wireless adapter is great. I'm using it with the Linksys WRT600N Router. I've heard that people have had issues using the Linksys wireless utility that gets installed when you run the startup CD, so I installed the adapter first, and then when windows prompted me for a driver I put the cd in. That way I just used the CD for the drivers and did not install the wireless utility that comes with it. I haven't had any issues using the standard Windows wireless configuration tools. I would also recommend changing the radio band on the Linksys WRT600N router from Auto to the Wide-40mhz channel (for the 5ghz network only, leaving the 2.4ghz wireless network setting to auto) then connect to the 5ghz network using the WPC600N and have all of your other b, g and 2.4ghz-N devices connect to the 2.4ghz wireless network. This setup has worked great for me, I'm really happy with both products.
