Sharp LC40LE810UN 40" 1080p 120Hz LED Edge-lit LCD HDTV Review

Sharp LC40LE810UN 40 1080p 120Hz LED Edge-lit LCD HDTV
Average Reviews:

(More customer reviews)
I already own 4 Sharp LCD TV's. This TV is to replace my bedroom 37" Sharp LCD that is about 6 years old (still works great, but will be putting it in my kids' playroom).
So, after looking around at all the different brands I decided once again to buy a Sharp, the LC-40LE810UN. Reading about all the nice features of this unit, including the introduction of the new color (yellow) technology is what did it for me.
After 1 week of using my new TV I am happy to report I made a great choice picking this unit. I explain the main points why:
* LED technology provides cleaner, brighter lighting. This is apparent as soon as you turn on the TV. As this unit is edge lit, not sure I see a difference between it, or a back lit LED unit. Need more time to evaluate this I guess.
*Adding yellow as a fourth color is definitely noticeable, and I like it. As most people know plasma TV's give you better color than LCD TV's. My Panasonic plasma TV is proof of this. However, I believe the LC-40LE810UN is a step up in LCD technology that brings it closer to plasma-like colors.
* Overall picture quality is excellent.
*The speakers are great, clear and loud. To me this is a major improvement for Sharp as their speakers are always horrible (like on the other Sharp units I have).
*The picture and sound adjustment options are plentiful and easy to use. This has always been the case with every Sharp TV I've owned. This one is slightly better/more user friendly.
*The unit is very well built and elegant looking, especially the glass base.

In closing, I am definitely recommending the LC-40LE810UN to all. You'll really like it!

Linksys by Cisco WAP4400N Wireless-N Access Point - PoE Review

Linksys by Cisco WAP4400N Wireless-N Access Point - PoE

I read the prior reviews but went ahead and bought this on the advise of a friend who intalls wireless networks for a living and he uses this access point a lot. I am completly pleased with this Linksys product. When you plan to use it for what it is designed for, an Access point, and don't have any notions that it is anything more, it chugs right along. I ran CAT 6 cable, (keeping under 300 meters total length) and used the AC adaptor supplied to power the unit. It is ran off a Linksys wireless-N router and a 5 station Linksys Workgroup hub. I mounted it in the downstairs coat closet behind my TV room and turned on my laptop, found it, and connected. I then entered it's webbased setup utility and configured it to my liking, (WPA2 security to match my wireless router) and I works like a charm. I am writing this review on my laptop, in my bedroom, where my upstairs router alone could never reach. I now have full bar service all over my complete property, inside and out. It is just what was needed.

ASUS PCI-G31 - Wireless PCI Adapter - 802.11b/g Review

ASUS PCI-G31 - Wireless PCI Adapter - 802.11b/g
Average Reviews:

I just upgraded my main PC and wanted to create a media server in the living room from my old box. It only had a CAT-5 on-board network adapter so I needed a wireless card. This is great for the money - does exactly what it's supposed to do. The router is on the opposite side of the wall about 6' away, so of course the signal strength comes in 100%.
It was not immediately recognized by Windows XP SP3, but I just ran the autoplay from the CD and installed everything from there. The mistake was to use ASUS' proprietary network manager and disable Windows' network manager. The ASUS network manager looks like something from 1995 and works like it too. It's just some other piece of junk to run in the background to hog more resources. It can connect just fine, but you have to navigate to several screens to connect. Also, it claims that it will save your password and settings, but it never does. So, I have to manually connect and enter the password every time I boot up -- lame!
Just install the drivers and bypass the ASUS network manager install and you'll be very satisfied.

Belkin Wireless N 4-Port Router Review

Belkin Wireless N 4-Port Router
Average Reviews:

(More customer reviews)
To begin, I purchased this router less than a few weeks before Christmas. This is actually my first wireless router (I had always used wired routers before), but I was able to plug it in, and connect perfectly fine. In less than 30 minutes, I was able to set it up, and my wired connections worked perfectly fine. Only problem was that the wireless didn't work at all.
I've struggled with the wireless for a week after I got this router. The problem was that upon first setting up the router, it would work fine, but as soon as you implement new settings (port forwarding or wireless security, for example), it would suddenly stop working. I found that hard resetting was the only way to get the wireless to work, but of course, leaving it as thus was unacceptable because I wanted to at least set up wireless security to prevent outside access. Unfortunately, after a few hours of struggling with this, it resulted in the wireless not working at all. Hard resetting, powercycling, reinstalling the firmware; nothing worked.
As a computer hobbyist, I usually pride myself on being able to fix things like this myself, but even I wasn't able to do anything. Needless to say, I had to call tech support. I may as well say here that tech support is absolutely worthless. I was routed to, where else, India, and got on with a tech support representative. I was led through the basic steps (and had to ask the rep. to repeat multiple times because I couldn't understand) and, at the end, the wireless still wouldn't work. The rep kept insisting that wireless isn't working for me simply because I either didn't have 'the drivers' or the 'proper wireless adapter'. Finally, I just had enough, and I was on my own getting the wireless to work again.
Just as I was having serious thoughts about making a return, however, I somehow managed to get the wireless to work. I must have had help from God because, at that point, it had seemed hopeless. Nonetheless, I did manage to get it working fine. I could port forward, set up wireless security, and basically do anything just fine. Unfortunately, it's not completely problems free. Like others, I have and am experiencing random connection drops (it seems as if the router randomly resets), but fortunately, it did not stop the wireless from working anymore. Furthermore, the Belkin Wireless N resets extremely quickly, so it's not as big of a deal as the previous problem to me.
Now that I am able to get the router working fine, let me review the actual router itself. Here is how the Belkin Wireless N ranks in the important areas of range, speed, security, stability, and features.
1) Range - I, like many others, purchased the Belkin Wireless N for the purpose of using the wireless feature. As such, one of the most important features to me is the range. After all, I didn't purchase a wireless router just to be confined to a single room because the range wouldn't extent past the walls. So then, how does the router rank in range? I would say it is fairly good.
I live in a three story house and the router is set up on the third floor. On the third floor and the second floor, the connection power is fully strong. However, on the first floor, the range just drops tremendously. On the first floor at the best location, the number of connection bars is usually one or two, which is a big drop. I suspect that there may be electronic interference.
For what it's worth, the range does seem to be pretty excellent, which is a commendable point on the Belkin Wireless N's part.
2) Speed - Of course, what worth is the range if there is no speed? I have tested the speed using the wired connections and the wireless connections and this is another commendable part of the router. The speed is just as fast wireless as it is with wired connections and both compares favorably with my previous router (all three matches the speed advertised by my ISP).
Truthfully, I had expected some loss of speed when using wireless, so this was impressive. It should be noted, however, that I was in the optimal position for speed testing (i.e. I was sitting right next to the router), so more likely than not, there would not some loss of speed if I had performed the test, say, on another floor in my house.
Regardless, the speed factor is definitely a category the router does well in.
3) Security - The Belkin Wireless N offers ample security to protect against outside invaders jumping on your network. From the simple WEP to the much more powerful WPA2 (I chose that one, of course), it really is nice security. Furthermore, if you chose one of the more simple security, the router actually offers an extra step of further encrypting the password for you.
Personally, I did not like the second encryption, but it is a nice thought nonetheless. I rank the router well in the category of security.
4) Stability - Well, as noted by the first four paragraphs of this review, stability is the one category the Belkin Wireless N fails miserably in (that and tech support anyway). Aside from the trouble of setting up the wireless to work correctly, however, there is also the problem of random dropped connections, which is fortunately mitigated by the router's ability to reset quickly, but it is still a problem nonetheless.
Aside from these problems, however, which can be solved through a router update (if Belkin ever decides to make another update, that is), the router really does not lose much else in the area of stability.
5) Features - Another category in which the Belkin router does well. The router comes with ample features which can all be found on the router's homepage. All the basic features and many more advanced features are here for the users' desire.
Personally, I have no use for many of the extra features (aside from port forwarding), so it's not a big deal for me, but the gesture is still appreciated nonetheless.Alright then, so out of five categories, the Belkin Wireless N does smashingly in four of them. One would think this speaks favorably of them, but lets look at the realistic side: For the vast majority of consumers, only three of those categories truly matters. Those three categories are the range, speed, and stability. The Belkin router does well in two of them, but it fails in the last one spectacularly.
Furthermore, unfortunately for Belkin, many other routers offers excellent speed and range too, so doing well in just those two categories is not necessarily enough to make it pass with flying colors. It really was crucial that Belkin made its router stable and it is unfortunate that it was unable to do this well enough.
Overall, what would be my recommendation for the Belkin Wireless N? My recommendation is this: If you're knowledgeable about computers and is willing to work at getting a slick and powerful router to work, then the Belkin Wireless N is not completely bad. However, if you're just looking for a simple wireless solution, I would recommend a better router.

The Belkin N Wireless Router uses the Wireless N protocol to provide an ultra-fast and reliable wireless network for your apartment or office. Offering outstanding performance, this router can handle the most demanding tasks, letting you stream HD video at the same time your kids are playing online games and sharing photos with their friends.
Smart Design with Wired and Wireless Connections The Wireless N Router has a striking, vertical enclosure that is both handsome and space efficient. The two built-in external antennas provide a wireless range of up to 1,200 feet and easily covers an apartment or small office. Six LEDs for Security, Wireless, Wired, Router, Modem, and Internet let you know the status of your network at a glance, making it easy to troubleshoot any problems.
Wireless N uses the latest 802.11n Draft 2.0 technology, offering better range and throughput than 802.11g and 802.11b networks. By using smart MIMO (multiple-input and multiple-output) antenna technology, the range of a Wireless N network is extended and can blanket a large home.
With wireless speeds of up to 300Mbps, you won't be waiting for videos to buffer or music to download because your children are playing online games. Wireless N provides more than enough bandwidth to make crystal-clear Internet phone calls, transfer a large amount of photos, and stream movies to your computer without any lag or hiccups.
You can also share networked peripherals such as a Wi-Fi printer, hard drives, and DVDs. If you have some computers that use the older wireless standards, they'll still work because the Wireless N router is backwards compatible with 802.11g and 802.11b devices (though they won't connect at the same blistering speed). For maximum speed and range, Belkin's N Wireless USB Adapter, Notebook Card, and ExpressCard adapter are recommended.
In addition to Wireless N, the router also has four 10/100 Ethernet ports at the back, giving you the option to plug in for a steady and secure, fast connection running at up to 100Mbps.
Thanks to the strong built-in security, including support for WPA, WPA2, Wi-Fi Protected Setup, and 64-and 128-bit WEP encryption, you will be protected from hackers and intruders trying to gain access to your sensitive files. Setting up security is simple, too: just push the Wi-Fi Protected Setup button located on the front of the router. The router also supports VPN for making secure connections between home and office.
Easy to Set Up Belkin designed the Wireless N Router to be as simple to use as possible. Simply connect your wireless router to your cable or DSL modem, plug the router in, and connect your computer to the router. That's it. To help monitor your network performance and usage, the router includes Personal Network Assistant software, which runs on Windows XP/Vista and Mac OS X 10.4/10.5.
The Belkin N Wireless router is backed by a 1-year warranty and includes free 24/7 technical support.
