PN:

I think E was rappin bout wifi itself.

Alright bud here it is....

A.)

First and foremost here are some things that can interfere greatly with WiFi connections drastically slowing you down.

PROBLEM:
- Channel congestion.

If everyone is using the same Wi-Fi channel - which usually co-insides with the default channel 6 on most wireless routers you usually end up with enormous amount of A fight (usually A fight with your neighbors over the best channel frequency) which leads to interference which leads to powerloss which leads to signal degradation which leads to your router having to sacrifice speed for power which leads to A slow internet connection.

Everything from fluorescent lighting to baby monitors.
Anything that puts out A sound.
Keep in mind frequencies are simply high pitched sounds the human ear cannot interpret.

Wi-Fi congestion is usually the bases for signal loss which causes slower speeds..

Solution (S):
o A good rule of thumb is to do A scan using your Wi-Fi adapter to see what
surrounding access points are using for there primary channels and set your wireless equipments primary channel to something that of the exact opposite.

EG: If most of the wireless routers in your immediate area where you will be surfing are using channel 6 , then changing your wireless AP to channel 1 or 11 would help your adapter to better communicate with your chosen router in this environment.

o If you don't have the ability to change YOUR AP signal you might be able to convince your neighbors it might be in A better interest to change theirs.
( So you are not competing with each others carrier signal frequency )

o And if all of the above don't help perhaps changing the position of the actual equipment might just do the trick.

Problem
- Signal degradation

Not everyone realizes that some Wi-Fi routers
(Like the ones found in coffee shops and airports and similar)
are simply repeated signals like the ones used in commercial cellphone repeaters. While this might work well and euphorically for A concurant connection like cellular voice signals operating on A proprietary codec using very small amounts of bandwidth in A stream high speed data is usually not meant for such burstable packets; especially with graphics intensive web pages like flash and hypertext.

In a case where to many Wi-Fi repeaters are being used
(and often times not setup optimally) , Latency can suffer greatly - which leads to slow connection.

Here is A prime example of Wi-Fi repeaters being used to serve A single connection using RuckusWireless's different mesh and zone technologys.

As you can see also- if multiple people are using the meshed access points that are being fed from A single "pipe" then this can cause signal degradation.

Solution(s)

o Here's A biggy.
Signal encryption. I know not everyone likes to encrypt there signal so I have A solution for that as well. If you have the extra resources try setting up multiple access points with the same name but one being encrypted and the other not. This would still allow your "guests" the freedom of utilizing wireless mobility but would give you piece of mind that you have control over the resources they are allocated.

In laymens terms you can throttle them to whatever you feel comfortable with, without cutting them off and at the same time keeping your surfing speed at your most comfortable and optimal level.

o Equipment placement!

If I had to count the amount of times I have come across improperly placed wireless network equipment that should overlap to the most optimal placement I would be very (as the president would put it) well-to-do .
Most consumers don't take into account things like weather and terrain in the placement of there wireless equipment for outdoor weatherized routers, or take into account things like signal interferences like wireless baby monitors or fluorescent lighting with indoor ones.

Be sure to give yourself some extra signal overlap when deploying A network of more than 2 wireless routers .

A little extra leeway can go A long way.

PROBLEM

- SPAM

Yes, unfortunately it plagues our browsing as well.
And while I agree with some using Ad-Blocking programs can help A little, they do little to stop the spams packet data from reaching your network.

SOLUTION !

o "Blackhole from the router NOT THE PC!"

What I would recommend doing is setting up what is called A PAC file or Blacklist file *DIRECTLY on your router itself* or using the windows PAC file itself.
Here you can add IP adress's of commonly used advertising agencies such as doubleclick and the like.

There are tons of guides on how to do this and even some tricks you can use on some older routers that might not have native support for this task.

Another little tip is to use this guide recently published by enGadget
(Especially if you are using A mac and a Airport base station)

http://www.engadget.com/2009/05/01/how-to-set-up-dual-band-wifi-and-juice-your-downloads/

Don't forget if all else fails you always have the option in the future of upgrading your hardware.
There are some amazing things coming just around the corner.

Including but not limited to A _TRI_ Band
802.11ABGN(WIFI)/FM/ AND Bluetooth 3.0 chip being released by broadcom that will nock the socks off any Wireless-G device currently being used.

As well as the first beam conforming 802.11N Access point being released by ruckus wireless.

One thing is for sure.
It's an exciting time to be alive !

Kind Regards,
XDS
