WAP54G very slow compared to WAP55AG

[wweide@shrinenet.org]

WAP54G, ver 3.04 12/27/07, Default settings except IP Address, no security, broadcast SSID.

I have multiple WAP54G Access Points configured to be Access Points.  They are all on different channels, broadcasting the same SSID. When I connect to any of them via wireless, my "speed" crawls... to the point of failing to load even Google or MSN.  My connection status via my wireless connection on my laptop shows Excellent/54MB. When connecting directly to switch, HP2524, get full speed (10MBPS Up/Down).  When I install one of my defaulty configured WAP55AG Access Points, (except IP Address), to the same location, in place of one of the WAP54G Access Points, I get full speed, or just shy of it.  This is a new installation of these WAP54G devices, so I cannot say if they EVER worked at full speed.  I have updated the Firmware, tweaked almost every setting, including the Fragmentation Threshold and RTS Threshold without any success. 

I had planned to implement about 8 of these access points throughout my facility for our "public" wireless.  My other wireless network runs over Cisco AP1131 in conjunction with a WLC 4404.  Both of these wireless networks are in the same location, but even with the AP1131's turned off... completely powered down... the wifi provided by the WAP54G's crawls.

Any help is appreciated.

Thanks!

Make sure the IP Addresses of your access points are not in conflict.

Make sure the channels don't go beyond channels 1, 6, 9, and 11. These channels are safe to use. 

Try these and tell me what happens.

Thank you for the reply.

The IP addresses were not in conflict, the two wireless networks are completely different, one a 172.x.x.x and the other a 10.x.x.x.  As far as the channels, the Cisco network runs on 1, 6, 11, so I have stayed away from them with the Linksys.

In further troubleshooting, I found that the system simply will not run efficiently when using the same SSID.  When I set the SSID for the AP's to the same one, ie; "Public_WiFi", the traffic throughput is varied, from 750KB to 3.5MB.  When I set each SSID to individual AP's, I get almost similar throughput as with the WAP55AG, 6.5MB to 8.5MB.  The WAP55AG consistently has a speed of 9.5MB to 9.8MB.  (I have a 10MB UP/DOWN direct Uplink to my ISP).

I have had to set up my AP's with Mixed mode (B & G), separate SSID's, Disabled Frame Burst, Beacon at 30, DTM at 3, Fragmentation at 1500, RTS at 1500.  When set to only "G", the responsiveness is slower than with mixed.  As I said before, it seems the major roadblock was the SSID.  When I set this to separate ones, the floodgate opened.  Not sure why this would be... as the AP's are not on top of each other, and I was troubleshooting directly under each AP, so I can't see that the system would be fighting to find the best AP to connect to.  It was pretty clear which one was the best signal.  The edges overlap probably about 15% or so.

Having the SSID's different per AP is ok since the users won't be roaming around, just in their assigned location... but I would have preferred to have one SSID instead of many for ease of administration.

Any thoughts on this?
