I feel it is necessary to give my review on the EnGenius ERB9250 2.4 GHZ 300 Mbps Wireless N Range Extender to help others like myself with bad wireless connections. 03-15-2011-update My Linksys WRT600N router blew the 2.4 Ghz circuit (5-6 years old), the 5.0 Ghz remained, but this is the signal that doesn't penetrate walls. I now have a new EnGenius ESR 9855G Wireless N, 2.4 Ghtz-only router. This is working fine. The remaining content is based on my Linksys WRT 600N wireless router. I have used in the past a Linksys WRE54G - G Range Expander b/g with a with a Linksys WRT54G router to the same location. I am currently running 300Mbps with an excellent signal. In the past my Linksys WRE 54 G range expander had a maximum 54 Mbps with a fair to poor signal strength, used in combination with the WRT600N router and a HP premium "N" adapter. This old setup ran typically 2-20 Mbps with a fair to poor signal.
I am technical average, below average or novice when it comes to wireless networking. After reading someone's comment maybe I'm an expert and just doesn't know it. I have spent hours enhancing locations, changing configurations, and praying for a decent signal. I have by pure accident discovered solutions to problems that no one ever addresses. I've come to the conclusion that the advanced techs out there work for the manufactures sales department and really don't understand wireless systems and their wireless routers. Very seldom can you actually talk with someone. If you do get a hold of someone, they seem to know a lot less than me, which is frightening.
I have a home office in a separate building from my home. The nearest exterior stucco wall to exterior stucco wall is 17 feet. I have my WRT600N (now ESR 9855G) wireless router in my family room which is a straight 49 feet from my EnGenius ERB9250 Range Expander in my office. The Range Expander is 7 feet from my computer. The signal is going through 3 walls with windows.

Number 1 -Important Things That All Web Sites Stress -you can just ignore. You REALLY DO NOT need to pay attention to: 1) line of sight (you shouldn't have obstacles) between the router and the range expander. They must be living in a tent, but I really don't know anyone that is so lucky as to not have obstacles i their way. DUMB LESSONS are important lessons or information I have learned creating a decent wireless network and is probably more information than what you need. DUMB MISTAKES are mistakes I made, but because of frustrations, and trying to think logically when I am tired and frustrated; these mistakes have eaten a tremendous amount of my time and were quite easy to fix.
Dumb Lesson #1 the 2.4 GHz setting is to broadcast all Wireless N, Wireless G, and Wireless B systems all at the same time on all this same frequency. REMEMBER THIS RANGE EXPANDER (WRT600N) IS USING ONLY THE 2.4GHz part of the Wireless Router, not the 5.0GHz. My new router only broadcasts in 2.4 GHz. I originally thought that 5.0 Ghz was only N systems, and 2.4 Ghz was only B or G systems, wrong. 2.4 can be for all three. A, B, G, and N are just standards. N is the most recent allowing higher transfer speeds and more unused frequencies. The frequencies are by far the most misunderstood.
Dumb lesson # 2, Misinformation is very prevalent even from known authorities. Just remember, this is part of the problem we all deal with and affects our judgment, when we try to make improvements to our wireless networks. The higher the frequency the more likely it will penetrate walls. This is the complete opposite from what all the wireless geeks say. 5.0 GHz will do better than 2.4GHz going through walls. This is straight from my engineer father-in law who helped put the lander on the moon. So ignore what is being said by so called experts, I am a wireless novice with real scientific information. 5.0 GHZ has less distortion from other electronic products in your home. Therefore it has a clearer less obstructed and distorted signal from other household devices. Items that can overlap the 2.4 GHz are: wireless telephones, remote controls, wireless game controls, microwaves, and many more. Ignore this concern. Using a wireless G router, my 2.4 GHz cordless phone blocked all wireless signals. I bought a new DECT 6.0 phone. No more problems. WHY 5.0 Ghz APPEEARS TO BE WORSE is that 5.0 Ghz takes an extremely large amount of power to go the same distance as 2.4GHz, which the best consumer wireless routers don't have. The router and adapters signals are really going around walls and through windows to best of their abilities. My need has been getting my wireless signal to a far distance with a decent signal and decent speed. The 2.4 GHz is the only way to go with the "N" standard setting allowing the faster transfer rates up to 300 Mbps and a much longer distance with a range expander. Maybe someday 5.0 Ghz wireless routers with be available with more power, but don't count on it with all the energy efficiency requirements.
For the WRT 600 N wireless router:
A) Get access to your router through the IP address using your web browser at 192.168.1.1, click on the "Wireless" button next to "Set Up" - Basic Wireless settings the 5.0 GHz setting the 3 bottom categories for Radio Band, Wide Channel, Standard channel set all of them to AUTO. The Basic Settings for the bottom 2.4 GHz are Standard 20 MHz, Auto, and Auto. Under the 5.0 GHz -Wireless Mode setting, set it to Wireless N, Network Name SSID to something similar to your original network you have chosen, such as Digital add underscore media so you know what name you are looking for "Digital_media" and your regular Network to "Digital".
B) Under 2.4 GHz set the Wireless Mode to "Mixed." "Mixed" allows everyone in your network to use your Wireless Network no matter what kind of adapter they have (a, b, g, and n) for their computer. This is probably the biggest mistake and most misunderstood setting.
Dumb lesson # 3, I learned that the Dual Wireless Adapters will LOOK FOR MORE THAN ONE NETWORK AT THE SAME TIME, hence the name DUAL.
C) You need to set up your wireless adapters that are dual G & N adapters on each computer to do just that, by going to Control Panel, "Network" or "Network and the Internet", you need to get into the network adapter setting. It is very easy in Windows XP and Windows 7, which is what I use. The web also has good details on doing this.
D) If you have a Wireless Router N router always use security at least WPA2-Personal and give each of your network users the password, set the encryption at "AES". It is easiest to use the same password for 5.0 GHz as well as 2.4GHz. Remember old "B and A" standard adapters don't allow encryption. If you are using Older Network Adapters in your network of computers you can't have a WEP or WPA security password. The old computers and adapters don't allow encryptions and won't be able to connect to you network. My new ESR 9855G router allows up to 4 accounts using the same setup and guest users. I enable an additional account with a simple password for my visiting clients and friends and then uncheck the additional account box when they leave so it doesn't disrupt the 4 users and 2 businesses at my home.

Dumb lesson #4, The real reason the N standard is important is the transfer rates and MIMO. MIMO (Multiple Input, Multiple Output) refers to the ability of 802.11n and similar technologies to coordinate multiple simultaneous radio signals. MIMO increases both the range and throughput of a wireless network.
Dumb Lesson # 5, My wife would come to visit in my home office (separate building) in the late morning to see how my day was going. When she left my wireless signal disappeared. I was beginning to think she was really from Venus. This went on for 2 months and had me totally baffled. Solution - when she came to visit me in the morning I had my sliding glass door closed to keep the heat in the office. In the late morning after warming up outside, she left my office by opening the sliding glass door and closing the screen door behind her and saying, "enjoy the nice weather outside." My wire screen door was blocking my signal. I went down to the hardware store and replaced my screen with a heavy duty pet screen material made of some tough durable synthetic rubber/fiberglass material and I had my solution and signal back. I also replaced 2 other screen doors in my house, because of this issue. The signal strength did improve significantly.
DUMB MISTAKES WHEN TIRED AND SETTING UP THIS WIRELESS RANGE EXTENDER
Dumb mistake #1, I tried to setup my Wireless ERB9250 Range Expander using the "Manual Configuration," I plugged the LAN connection into the back of the wireless router for a network connection. Then I tried to go to the ISP 192.168.1.2. Wrong you must plug it into the wired LAN connection in the back of your computer's wired LAN connection. I had to reread the booklet. The online booklet doesn't specify this.
Dumb mistake #2, When I resolved my dumb mistake #1, and plugged it into the LAN connection, I went to ISP 192.168.2 and it wouldn't connect. It just said Windows Internet Explorer connection is not available. After scratching my head a few minutes, it dawned on me that I had to connect to the wired LAN (Local Area Network), not the wireless LAN. So I disabled the wireless adapter and allowed the computer to connect to LAN with ISP 192.168.1.2 and then followed the directions in the booklet. Note: it may be easier to print out the setup booklet online at EnGenius web site than to read the small size 6 font in the booklet, especially at night (see the missing note on the...Read more›
