Netgear WG121 Wireless 802.11g USB Adapter Review

Average Reviews:

(More customer reviews)I bought this same product. I use it with a Netgear 802.11g router. I use all Netgear products to hopefully prevent any conflicts between hardware, but I'm not an networking expert so I'm not sure if that will really prevent any problems. But from my POV this is a safe buy. No problems so far. What I like about this product is that i can place it on a high shelf out of the way of metal objects and other stuff that would potentially interfere with the radio signal, because it's connected by USB.

(More customer reviews)We have had no issues with this adapter. It works great; got us back up and running in no time. Router on one end of house, the adapter on other, works great. Not any more fickle than any other add-on adapter, probably less than others we've had. For the price, I don't think you can beat it!

Average Reviews:

(More customer reviews)I was inmpressed with the adapter till I connected it to my laptop. I installed the driver and the device worked right away. Then I wasn't impressed at all. The signal strength was very LOW and my connection was poor. I was only 20 feet away from my wireless router. I even tried moving the devices to gain teh signal strength but nothing worked. I turned off this device and turn on the internal laptop WIFI. The signal strenght was HIGH and my connection was excellent. I went back to the GSI adapter and the signal strenght did not improve. My connection never did get better than LOW. I am returning this adapter am may try a different one. Not impressed at all. Even updated the drivers from their website. Nothing work and my skill level is very advanced. My career is networking and I have an extensive background in RF as well.

Hawking HWUN1A Hi-Gain Wireless-300N USB Adapter with Upgradable Antennas for Mac Users Review

Average Reviews:

(More customer reviews)I ordered this for use as backup to the built-in Airport in my MacPro. I ran into couple of problems with the unit after installing it: even though the signal was very strong, the unit got massive amount of collision errors causing the web pages to display very slow and sluggish. After a call to their support, I was referred to their Engineering support since Tech support can't help. After couple of email exchanges, I was sent a new driver for the unit. After installing this driver the collision errors went away but the web pages were still displayed very slow. The stats screen showed large number of retries. Engineering support suspected interference caused the problem and suggested to switch to another channel. After switching the wireless router to another channel, the retries went away and the unit works great since. Don't know why the Airport did not have this problem but since it now works great I'm happy with it.
I'd recommend this unit for anyone who needs a backup, or has a need to use an external antenna for extended range.

GSI High-Powered Ultra-Secure 150Mbps USB 2.4 GHz Wireless WIFI Long Range Network Adapter - IEEE 802.11 b/g/n Interface - For PC/Laptop/Notebook/Computer Hot-Spot Internet Connection - Pocket Size For Travel or Home Use Review

Average Reviews:

(More customer reviews)I had ordered the GSI Adapter specifically for my MacBook Pro. Although it does work fairly well, the installation for the Mac was far from intuitive. It took some time to find the correct download/installation drive from the ones available online. However, the product has boosted whatever signal I have considerably. Although I still have the occasional trouble with my wireless signal dropping out entirely this happens with far less regularity as before. The program itself for wireless utility is easy to use and the adapter makes for a small and transportable addition to my laptop accessories. Overall much better than without, though not perfect.

+9dBi 15" 3x WiFi Booster Antenna for Netgear FM114P FVM318 FWG114P MA311 ME101 ME103 WG302 WG311 with RP-SMA Connector Review

Average Reviews:

(More customer reviews)+9dB 15" Booster Antenna for "Linksys" with RP-TNC Connector
To solve the mystery of how you can get gain out of what might appear to be a omni-directional whip: This is a collinear antenna which has coils built into it so that it acts like several vertical antennas are stacked on top of one another, each creating more gain as the radiation pattern is squashed down into the shape of a toroid or doughnut so that little power is received or transmitted either directly above or below the antenna and instead concentrated in a band around the center. If the Wi-Fi antenna you want to receive from is elevated above you then you would want this kind of a antenna to be swiveled in such a manner as to put the whip at a 90 degree orientation to the remote station to allow signal reception or transmission off of the sides of the whip where the power is greatest.
Due to the way the receive and transmit pattern is in the shape of a toroid or doughnut this type of antenna can give good gain while at the same time being omni-directional, except above and below the antenna where you don't need to waste the power anyway. If you want a antenna which has much higher gain look for a more directional antenna such as the flat panel antennas, Yagi or a parabolic reflector type of antenna which depending upon the size, can have 20 dB (or more) of gain which is a factor of 100 making a 100 milliwatt or 1/10 of a watt signal seem as powerful as a 10 watt signal, or a 1 watt signal as powerful as 100 watts. If you buy a flat panel Wi-Fi antenna and get one rated for 20 dBi of gain the half power beam width for both receive and transmit will be about 20 degrees. With a 20 dBi gain flat panel directional antenna, if you point it 10 degrees to the left or right from where it should be pointed for maximum signal you will have the equivalent of 17 dB of gain but that apparent gain will quickly drop off the further away the antenna is pointed from the proper direction. Note: It is a coincidence that a 20 dBi gain antenna has a 20 degree wide half power beamwidth, normally gain and half power beamwidth do not correlate to the same numbers except in the case of a 20 dBi gain antenna.
If you want to receive or transmit to two different locations at the same time but want each to have the best signal possible using a single high gain flat panel antenna, you can cut the difference between them sacrificing some of the gain to each one and point the antenna to an area in the middle. As long as the two stations are close enough together to be within a healthy portion of the antennas area of gain this should work out fine. Obviously, you wouldn't expect to be able to use that antenna for two different locations if one was behind you and the other in front but if both are within 30 degrees from you and not too far away a 20 dBi gain antenna could be used by cutting the difference between them. If they are too far separated in azimuth direction from you use a high gain collinear antenna with more power on each end, or perhaps using a lower gain antenna which has a much wider beamwidth or separate antennas for each radio shot. You can also use a splitter designed for 2.4 GHz and combine the receive and transmit from two separate antennas together into one feedline going back to your equipment, if necessary, but there will be a 3+ dB penalty or loss of signal level when doing so but to me this seems like the best solution if you need all the gain you can get from a flat panel or highly directional antenna to each station when using a common or single Wi-Fi transmitter and receiver such as a LinkSys or other wireless router.
Here is a good rule of thumb for line of sight radio shots without buildings or other terrain in between, every time you half the distance you increase the received power from a remote location by six dB, or if you double the distance you lose six more dB of signal level. In areas where there are trees and buildings or hills between each location this rule does not apply as the signal losses can be very great for short distances.

D-Link Wireless G USB 2.0 Adapter 802.11g, 54Mbps Review

Average Reviews:

(More customer reviews)I like this little gem. I had a PCI wireless card for my desktop that was several years old and no longer supported by the manufacturer. I needed to upgrade, but I wanted a USB wireless adapter this time around. I wanted to get it out from the bottom of my desk so I could a better signal. I had certain requirements for my new purchase. It couldn't cost any more than $45. It had to be USB. And it had to have some sort of USB extention cable or cradle. It had to be reviewed by Windows Vista users. It also had to have excellent reception. I don't have a big house, but there were a lot of walls and electronics near and in between the Access Point and my computer.
After searching I found the DLink Wireless G adapater fit the bill. I picked it up for $30 (at least $10 less than local stores). All of the reviews talked about great reception, even indepent review sites. And it had the USB craddle I was looking for. I bought it and got free shipping along with it! What a Deal!
I've had this little gem installed for about one month now, I coudn't be happier. It gets great reception. This adapter runs absolutely great with Vista. I am also using the included connection software and it plays very well with Vista.
The only downside is the optional craddle. It requires either a direct computer USB port, or a powered USB hub with an external power supply. It draws more mA than a non-powered hub can handle (at least it did on mine). I had to use the power supply on my USB hub to get the craddle to work. This is the only reason I give it 4 stars instead of 5.
I highly recommend this product. You will not be disappointed.

2000mW 2W 802.11g/n High-Gain USB Wireless G / N Long-Rang WiFi Network Adapter and Suction cup Window Mount dock *Strongest on the Market* Review

Average Reviews:

(More customer reviews)I bought this because my netbook's atheros was not pulling in very much.
I used xirrus and could only see about 2 to 3 users in my neighborhood.
I bought this and then went to install it.
NOTE: You do not just plug this in and let windows add a device driver.
You MUST run the installation prorgam from the CD that comes with it.
After running the install off of the CD, all was great.
The installation CD gives you an app that shows access points in your local vicinity.
Tells their type of connection (802.11b, or 802.11g or 802.11n)
Shows if their access point is open, or which type security is being used.
WEP,WPA, etc.
After installing this device, I reran xirrus.
Awesome! Instead of like 3 or 4 AP's in my area from my built in atheros wireless, I now found like 10-12.
Xirrus' radar screen view was now lit up with all sorts of dots, each indicating an access point.
To test range, I set in my vehicle, about 3 blocks away from Village inn.
I had no problem connecting to their AP and surfing.
My built-in atheros saw that there was a Village inn connection, but the signal was too low to even try to connect.
So far, it's the best usb add on wireless NIC I have found/used.

Alfa 2000Mw 2 Watt High Gain indoor or Outdoor 802.11b/g WiFi Booster and Signal Amplifier Review

Average Reviews:

(More customer reviews)Works well, and is at a fair to lower cost price. This 2 watt is just abit over the 1 watt. You can find documentation for it easily on the web. It uses a PS, into the small injector, which goes to the amp. The connectors are N females all around. You have to have a G type access point with output via cabling. Also, get a "yagi" type antenna (indoors - bidirectional or unidirectional). The kit came with the PS, and injector, and amp. Cords were on me, but I found adapters and cabling quickly, cheap too. A real good project. That's what I like doing, creating small systems such as these. You will have your neighbors hooked up in no time at whatever rate you charge, instead of feeding the big guys.

Average Reviews:

(More customer reviews)I read mixed reviews of this product, but decided to give it a try. I used it with two different laptops that have their own built-in adapters, in areas where signals were weak and inconsistent. In both cases, the signals were at least usable. It's not a miracle-worker, but there is a definite difference between the built-in adapters and this one. And because it is on a USB cable, the antenna has more positioning versatility than a whole computer does.

(More customer reviews)Purchased for use with a laptop that has 10.04 Lucid Lynx installed and it was pure plug n play! The reception is awesome. I expected it to be weaker than the installed internal wi-fi card on the laptop. 5 starts for the price! It does get very warm, but I use a cooling pad that is blowing on the laptop so it has not been an issue. Since I am using Linux I cannot comment on the install for Window$, but it did come with a driver CD-ROM. Shipping was fast too, I would buy again!
