I am setting up a large high school with PtP connections to all the builbings and I just started testing the 2.6Ghz P4 main AP which has 2 SR2 cards now but I am going to replace them with 4 CM9 cards. The client ends are rb532s with CM9 cards.
The thing that is making my crazy is that all I can get from the setup is 15mbps TCP. Thats testing from two 3.2Ghz PC on each side of the link.
I am using AP-bridge and the two wireless cards and ether1 are in a bridge. On the client rb532 I am running station-wds and bridgeing it to ether1.
I ran the tests and only got the 15 mbps speed so I tryed the same test on a 2.5Ghz pc as client and got the same speed.
Any idea why it’s so slow?
This could be because of the data rates, link quality, distance, etc…
ok, here’s what I have.
PC#1 3.2ghz PC with FTP server and MT Bandwidth Test Server.
PC#2 2Ghz Laptop with FTP Client and MT Bandwidth Test server.
RB#1 RB532 with SR5 miniPCI card and OS ver.2.9.24, AP-bridge WDS, Ether1 and Wlan1 in Bridge1
RB#2 RB532 with SR5 miniPCI card and OS ver.2.9.24, Station-WDS, ether1 and Wlan1 in Bridge1
Tests are running on the PCs.
The two RBs are sitting next to each other with no antennas.
I have PC#1 connected to RB#1 via ethernet, RB#1 wirelessly connects to RB#2, RB#2 connects to PC#2 via ethernet.
The Signal is -64 and the connection speed is 54mbps.
I have ran the BWT and it only gets 13.2 TCP rx or tx, but it gets 27mbps UDP.
The FTP client shows 2000kbps on transfers.
What’s the problem here?
update:
I have added antennas and I moved the things 6 feet and 20 feet away from each other. It has made no difference.
Still only 13 to 14 mbps TCP one way.
I tried the SR5s and the NMP8602s.
I have ordered more CM9s and R52s for testing.
Has anyone else had any speed issues?
I am routing it now and I get 21mbps from 532 to 532 with BW tester.
BUT if I run the BW tester on the two PCs I only get 12 to 13mbps.
WT@#$%& ?
Do you do the bwt in both directions?
see the cpu load on the 532
when you generate packages it is on 100% the load
do the bwt and see if ther is a broblem in your lan 
turn off connection-tracking?
remove ap-bridge out of bridge (you need only bridge wds + ether1) and set it in ‘bridge’ mode.
SR5’s…those are stronger than 65 mw cards? then they get hotter than the 65 mw cards..
limit supported-rates to 6mbps through 36mbps. set basic rate to 18 mbits only. (do on both sides)
You mean change the AP-Bridge to Bridge? And how should I set the client side?
I will try these things and let ya know how it goes.
PS Thanks for the help. It’s greatly appreciated.
Connection tracking is off.
