Wireless N = latest, Get an Airport Extreme Base Station
Here's a review I posted on Amazon about the Airport Extreme Base Station in 2009. Since then, our business has moved out of the house and into a new office space, and we just added 4 new employees last October. For our office, I bought another Apple Airport Extreme Base Station! I also bought a new 27" iMac. I'm not necessarily an Apple "fanboy", as I also like Windows 7 and Office 2010 (but not 2011, until they fix the bugs).
Anyhow, I hope this helps!
I work with my wife and we own our own business (actually, she's the sole owner). We have about 5 employees and 24 consulting instructors. We provide consulting services in portfolio / project management, program management, and systems engineering, as well as training in all of the above as well. Our clients include Northrop Grumman, Joint Forces Command, the USCG, and many more. As a result, we rely heavily on our computers and our network.
My office is currently downstairs near the router, and hers is upstairs (our building is 4600 sq ft). We needed more range, so after researching what I thought was the best router, I bought a new D-Link Wireless N Gigabit Router DIR-655 - Wireless router + 4-port switch - EN, Fast EN, Gigabit EN, 802.11b, 802.11g, 802.11n (draft), and Hawking HWREN1 Hi-Gain USB Wireless 300N Range Extender (White). Still didn't have great coverage, so I tried even replacing one of the 3 antennas on the back of the DLINK DIR 655 with the D-Link ANT24-0700 2.4 GHz Omni-Directional 7 dBi Indoor Antenna after a recommendation by an employee of the now defunct "Circuit City" store.
Still didn't help. And to top it off, every time I lost power, the Hawking and the DIR655 wouldn't work together. Hawking tech support in India (nice people, by the way) told me it was because they got stuck on different IP addresses. So the last guy I spoke with set them both to be on a static IP address together, which, while that worked, it seemed to slow my network speed, although I never verified that. I spent MANY HOURS solving connectivity problems between the Hawking and the DIR 655. And it even got to the point where, when using my iPhone 3GS in the house, I would skip the Hawking network connection when I had a choice between that and directly connecting to the DIR 655 because the Hawking always seemed to slow or fail with my connection.
Anyhow, after seeing an article about Apple Time Capsule MB765LL/A 1TB, I decided that since I'm running a Windows machine I couldn't use the features of that (Time Machine), but I could try Apple's Apple MB763LL/A AirPort Extreme Dual-band Base Station because it had multiple advantages over the DIR655, such as having a "Guest Network" where we could allow our guests (sometimes employees) to use our network when visiting but not have access to our systems. It also has a USB port to plug in a hard drive, and we could share that for easy large file transfer, etc. And, I could easily extend the network by adding an Apple AirPort Express with Air Tunes (M9470LL/A) - all one has to do is when setting it up, check a box that says "Extend my network". IMAGINE THAT! DESIGNED TO WORK TOGETHER! No more IP address conflicts! WOW! I have been amazed ever since how easy my network has become! And, I'm getting much better range. And if you have a need to extend the network in a different direction, you can simply add another Airport Express.
The odd thing is, neither employees of Best Buy, Circuit City, etc., ever recommended considering an Apple solution. I wish they had.
So, what has all of this done for me? Well, for one, I love my iPhone 3GS, and now I also love my Airport Extreme Base Station / Airport Express combination, so much so, that I decided to switch my PC to an Apple MacBook Pro! About 6 days ago, I ordered a Apple 17 MacBook Pro Intel Core 2 Duo 2.8GHz, 4GBRAM, 500GB 7200RPM Hard Drive, NVIDIA GeForce". And, it will be here today! What about my customers that use MS Office products? Well, my new MacBook Pro comes with Office 2008 for Mac, and, it also comes with Windows Vista Ultimate so I can still run the same software as before.
Couldn't arrive at a better time too. Yesterday morning, my HP Pavilion DV6675US 15.4-inch Entertainment Laptop (Intel Core 2 Duo Processor T7250, 4 GB RAM, 250 Hard Drive, Vista Ultimate)laptop had a Blue Screen of Death......
So, bottom line - if you're needing more network range, and haven't invested too much in your current setup, I would highly suggest you consider the Airport Extreme / Airport Express combination instead. So much easier to set up, doesn't fail, better range, and for me, you save yourself a lot of time. And when you're in your own business, as the old saying goes, time is money.
