The Wireless Neighbor War (Part 1)

April 14th, 2006 · No Comments

With the influx of wireless networks comes the wireless neighbor war. If your neighborhood has a lot of wireless networks, which one do you think interferes with yours??

One of the most common grievances about this problem is that each time a neighbor puts up a wireless network your wireless network is slower or you get booted off.

The easiest thing you can due is change your channel on your wireless router. Almost all wireless networks have default channel of 6. Change your wireless network channel to something try channel 11 first.

If you have the money purchases a MIMO wireless router. This will overpower one radio access points. The most common complaint regarding wireless interference is dropped packets. MIMO wireless routers let you transfer and receive at twice the rate because they have two transmitters and two receivers…or two radios!! This gives you a better quality signal and better coverage.

Another tip lies in the placement of your wireless router. If you have a wireless router in one of your edge bedrooms half you signal is being sent out of your house with the default dipole antennas.

If you are going to keep your default Di-pole antennas then you need place your router in the middle of your house away from large metal objects.

Learning the Ropes of WiFi Security (Part 3)

The idea was passed on from one company to another and so on. Later they went into the company to offer their services. Sure it might sound like a good and a win/win situation. It actually look like they were going to get away with it. But not so, the FBI High-Tech Crimes Division is all over the case.

Moreover, a recent GAO report as well as numerous other articles in Federal Computer Weekly, GovExec.com and other newsletters shows some concern as more than 1/3 of all government wireless networks are somewhat unsecured.

In order to learn more about this matter I have went out and consulted a former hacker and is now into security computer consultant. It seems that WEP or other such encryption is not even close to secure.

I think that in order to catch the International Terrorists Cells in the United States, everyone should get full time WiMax in every city and have an algorithm which looks for anomalies to see if you can catch those who surf all day Jihad websites, and see who they are? Now there is a thought “Reverse WiFi Hacking” to catch International Terrorists, why didn’t I think of that? Now you be the judge.

Learning the Ropes of WiFi Security (Part 2)

If you ask me, I think a lot of people buy these OTC peripherals and Linksys type systems and then simply put them in and turn them on. I know that one large Home Improvement Store did this and has fixed their units, but they were wide open.

A lot of small businesses everywhere are open, though they probably do not care. Meanwhile there are some who deliberately blast WiFi in order in order to increase customer base. Also they do this on different separate air-gapped systems from their store operations. For instance, if you take Bitpipe online you can get the latest white papers on these things. Therefore, it is important that you sign up for online security white papers.

Just recently, Florida was awestruck by case wherein someone was “War Driving” in order to pick up WiFi signals. He then stopped in front of someone’s house, as it turned out he accidentally loaded some programs and the icons that wind up on the host computer as well.

The police of course came in and arrested him. Meanwhile, in Silicon Valley another case was discovered but this one went on quite a bit. There were two-guys who sort of invented something.
