<DIV><FONT size=2>I have done some tests here as well (all this discussion about
speed has caused me to get out my ftp program and transfer some files around the
place !)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Test 1: 10mbps Hub to WL400 (75mw to 2 x 10dbi Omni's) when I
have a 11mbps Signal.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Transfering from a PC (with a 10/100 card) to a half duplex
hub onto the wireless back to the client I get 240-280KBps with 1mb 2mb 5mb 10mb
20mb files.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Test 2: Client to Wireless AP to Wireless AP to
Client</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Regardlesss of what I did they maxed out at 280KBps. Min was
75Kbps</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Test 3: Ping -f ( he he) from 6 machines on the network
to the AP, then transfer files, still 280KBps max min 220KBps...</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Looks like thats it max speed.... still its nice
!!</FONT></DIV>

<DIV><FONT face=Arial size=2>I did a bit more testing the other
night.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On my local Windows Access point, I can get up to
260 kilobytes/sec transfer rate from my laptop with a wireless card through
the AP to the wireless card that acts as a client on the linux router. Client
-> AP -> Client - 260Kbytes/sec. Both of the client cards were in range
of each other. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My thoughts are that because I didn't have
the hidden node problem, both clients could hear each other, the transfer rate
was higher. The other links to this local Access Point which are 400m links
(two of them) only achieve around 75kilobytes/sec. They both have LOS. They
have to route their traffic through the Wireless Card on the linux router (as
previously mentioned), but in theory they should be able to do the 260 KB/sec
I can with my laptop.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any idea's on how to speed the transfer rates
up?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Just thought I would share my
findings.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi Guy's,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Over on our Digicate Nodes in the Beenleigh
area, this is the sort of performance I have found (I am trying to up the
performance but I believe I might need to fiddle with RTS/CTS values or
possibly look at some driver changes. Hidden Nodes seem to be a major factor
in performance problems. There are some special windows drivers that use a
Turbo Cell custom mode that only works with Karnet Access Points that are
supposed to optimise the network bandwidth via some polling
arrangement).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Firstly, we find if someone is doing a major
file transfer, they knock out the weaker nodes (mainly our 7.5km Client
node) under the large file transfer is done. We are using an Apple Airport
(Lucent Silver card 8.10 firmware) as our main AP, all other cards are
Cabletron Roamabouts running 6.06 to 8.10 firmwares.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Transfer speed</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Wired client > Client Node (linux
router) > AP > Wired Client (hanging off the access poing) ~ 450
to 500 Kb/sec</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Client Node > AP > Client Node, between
75Kb to 100 Kb/sec</FONT></DIV>
<DIV><FONT face=Arial size=2>Client Node (linux router) > AP > Client
Node (7.5 Km link) ~ 50Kb /sec</FONT></DIV>
<DIV><FONT face=Arial size=2>Client Node (7.5 Km) > AP > wired client
~ 150Kb/sec</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We also have a second access point running
under Windows (with driver hacks) but it does not seem to allow the traffic
to pass to the Windows PC to be routed over Ethernet. Thus we use a second
Wireless Card to route traffic via this Windows Access Point. Performance
seems to be between 75Kb/sec and 120 Kb/sec. If the Windows drivers can be
modified to allow local routing of the traffic over its ethernet interface,
then I assume we should be able to get close to 450 - 500 Kb/sec (Client
-> Ap -> wired)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Anyone know what all the values are for the
lucent drivers in the registry? Anyone got a Linux AP driver for Lucent /
Cabletron cards?</FONT></DIV>
