First of all, after reading the 300mbps sticky I realize I'm not going to get that kind of speed.  However I am able to get between 120mps to 150mps with xp pro and trendnet tew643pi adapters.  It seem it shows the 120-150 mps when I'm not using any applications but when I use a program (games especially) I get 60mps after several minutes of play.  I believe I've forwarded the appropriate ports and only use mac filtering.  I have the router set at 100mps and set to receive only "n" signals (before i did this I could not connect at anything higher than "g" speeds.  The only thing I see thats questionable is the noise level -47db which seems rather high to me.  Could this be my problem? or is there a better place to check for the constant speed drops?

Forgot to mention signal strength is "very good,getting all bars on the trendnet signal strength software"

-47 dBm strikes me as a noisy environment (mine flirts around -96m).  I wonder if that's the cause right there.  Any other 2.4 GHz users around (phones, baby monitors, wireless speakers, etc.)?  Anything that would throw noise across spectrum (dimmers, touch-lights, fluorescent lights, air purifiers, or other stuff that puts static on AM radios)?

First, you should confirm that you're actually getting a throughput drop at the lower wireless bitrates.  The bitrates are supposed to float in order to maximize throughput (useful data). 

For example, if the error rate is high at 120 Mbps but low at 60 Mbps, you probably want it to float to 60 during these times because the amount of actual error-free data it can deliver per second is higher.

I have two computers both on the network right next to each other (almost touching).  Could that be the cause?  I have 900mhz phones in the house but thats about it.

How would I check the error rate and check throughput drop as you suggested.  I'm new to wifi networking! and thanks for your reply.

If you're new, I'd probably just set to to Automatic.   But if you're technical or curious, you can test and observe. 

If they're configured for file sharing, then transfer a 10-20 MB   and then transfer it back.  Look at throughput -- don't worry about looking at the error rate, throughput is what you'll care about and throughput is inversely proportionate to error rate. 

Do this with the Setup - Wireless - "Wireless Rate" fixed at the various rates and then set at "automatic"

I have two computers both on the network right next to each other (almost touching).

If the cases are closed and all the connections are tight then computers shouldn't be too bad of a nose source.  (Turn one off and check the noise level on the other with it off.)

These shouldn't be a problem.
