<DIV><FONT face=Arial size=2>Hello... Here is a follow-up and more
information concerning my last post about WDS Speeds... dont know how
much of this will be helpful, but here we go. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>My test machines are: </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>AP-A Celeron3 533</FONT> <FONT
face=Arial size=2>with 64Mb. SuSE 8.0 , 4/2/03 Hostap CVS. Linksys
wpc11 pcmcia card in a pci/pcmcia bridge. i used the minimun install and added
just what i needed (pico, wireless tools, etc) to create a hostap
box.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>AP-B p90 with 64Mb. SuSE 8.0, same software, CVS,
etc. Linksys wpc11 pcmcia card in a Linksys PLX adapter
(pci).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I compiled the hostap driver with
PRISM2_DOWNLOAD_SUPPORT turned on, and using prism2_srec i install intersil's
1.5.6 FW image to RAM (not flash), thereby endingup with:</FONT></DIV>
<DIV><FONT face=Arial size=2>NICID: 0x8002 v1.0.0</FONT></DIV>
<DIV><FONT face=Arial size=2>PRIID: 0x0015 v0.3.0</FONT></DIV>
<DIV><FONT face=Arial size=2>STAID: 0x001f v1.5.6</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I found a FTP server on my local net (10.0...)
thereby bypassing any routing, for my testing (Im trying to get an idea of the
bandwidth available using WDS).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Command line FTP from AP-A (which has the
wired connect to the network), i get 6.3 MEGABYTES/sec download. AP-A is hooked
to the same switch as the ftp server. (for comparison, a machine
daisy-chained one more switch out from the ftp server gets 5.9 MEGABYTES/sec
download).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Command line FTP from AP-B (which has a WDS link to
AP-A ONLY) gets </FONT></DIV>
<DIV><FONT face=Arial size=2>90 KILOBYTES/sec downloadspeed !! :(
!!!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A client machine (win98 laptop using ftp
program) associated to AP-B gets </FONT></DIV>
<DIV><FONT face=Arial size=2>83 KILOBYTES/secdownload speed. If I
walk to where AP-A is, the client computer will then roam to AP-A
(like i thought it should). Without loseing the download that was
running!! :) The speed then, with the client associated to AP-A
is 260 KILOBYTES/sec, although this is slow, its much more acceptable than
90Kb/sec. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It occured to me, as i was typing this that alot of
my problem might be the wireless link between AP-A and AP-B, doin some figuring
i discovered that 1Mbit is appx = to 100Kb/sec (hope i figured this correct),
anyway with this in mind, 90Kb/sec isnt out of line. tomorrow i will move
AP-B within range so that a maximum connect speed can be established, then see
how it runs...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, (if anyone besides me is interested) i will
reverse the situation and make AP-A become AP-B and viceversa and see how the
numbers do...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do my benchmarks seem consistant? or are they
unusual as they seem to me? </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Please everyone, post your comments and thoughts
all input is appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2>oh. the question is: what happens to all the
bandwidth over a WDS link...?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
