Re: [Karlnet] Transfer Rates

[Bryan <blsutton@airnetwifi.net>]

Interesting - I was just getting ready to purchase KN-200s to resolve 
that very same issue, I was using Orinoco AP2000s and having same 
problem.  I will hold hold off pending a resultion to your problem - no 
sense spending the money for new equipment with same problem.

I proved to Proxim that it wasn't a network congestion problem or a 
problem with the internet speed tests by:
1. Setting up an FTP server internal on my network.
2. Shutting off all customers - this wasn't much of an issue as I was 
testing network and only had people that were willing to use for free, 
under the understanding that it could go down at any time.
3. Repeatedly DLing & ULing a 120meg file from server to laptop & back, 
at vatious points in the network while watching with DU Meter.

As for your Ping test - it would seem to me that if you are Rxing ~3.4 
mbps ROUND TRIP - since thisis  half duplex the one way should be 2x 
that or 6.8mbps...?????

Personnally - I don't give rat's @ss about any latency tests or any 
other built in tests - Those can be manipulated by the writer of the 
software to show favorable results.  The only thing a customer, and 
therefore myself, cares about is that if they are being sold a service 
at particular speed, they get it.  The only way to prove that is to have 
an internal network speed test of some sort.

Here what they told me would support upto 1mbps thruput to customers at 
any point in the network (using TC for backhaul on one radio -the other 
radio to serve customers)


Anyone using a network in similiar config, i.e. 4 wireless backhauls, 
that can verify this?
