In Btest window, change TCP Connection Count to 1, and make another test. Put results here, then I can explain you why the results are like you descibed.Hi All,
I have just setup a link for a customer using a pair of RB411AH, Mikrotik > Mikrotik is doing 80mbps TCP using the test tool however from a windows machine running the iwndows BW tool I only see 40mbps tcp and this is reflecting the internet speed also which is topping out around 45mbps with a 100mbps connection on the other end.
I have check everything I can think of, CPU load on both devices is between 35 - 45% at 45mbps, If I plug in directly on the other end the internet connection is doing roughly 120mbps.
Any pointers? or suggestions.
Now everything looks like it should. `
What antennas do you have there? -59 on one chain, and -72 on second... it looks like antenna problem.Ok so I switched one of the chains around as it was mismatched and tried to align the antennas a little better and now it looks like this: http://dl.dropbox.com/u/8790688/Mikrotik3.PNG
Remember that TCP i a protocol that use duplex connections. It sends ack, so making one side ccq better can't solve 100% of your the problem.Hi,
So I havent had a chance to check the antenna at the primary site yet so I switched the AP to send on the good Signal/Condition Chain and recieve on the misaligned chain and the ClientAP the oposite as below:
As you can see the Signal and CCQ is now perfect for the recieve chain:
However we are still only able to on 1 connection get 35 - 45mbps and 4 connections we get 75mbps/100% cpu
So Any ideas how with 100% CCQ and 150mbps on the chain 100% of the time how to achieve a higher single TCP session throughput?
