<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>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>
