Cisco 1121G Wirless Access point speed issue.

Posted on 2007-09-29

I have a Cisco 1121G Wireless access point with a Cisco ASA5505 firewall. When I plug a PC into the firewall directly, I do a speed test from my cable modem and get 29-30mbits/sec. When I connect with my wireless G card in my laptop to the AP, I can only seem to get around 8-8.1mbit/sec. I have gone through all the settings on the AP, and set it up to ONLY allow G connections. This increased my speed from about 7.9mbit/sec to the 8.1 I am getting now. My other laptop has a Cisco G card and the results are about the same. Does anyone know of any restrictions on the Cisco 1121G AP's, or has anyone experienced the same issue? Also, I have tried the AP in Powered and PoE setups with the same results.
Any ideas?

    Check these things:
    1) Your speed and duplex settings for the Ethernet connection from the AP to the Firewall.  Make sure they are set to 100 Mbps Full Duplex (hard coded).  If you have a switch in between, check that as well.
    2) On your AP, try a different channel for the wireless.  You may be experiencing interference, especially if you live in a densely populated area.

    Got those down...but I still can't seem to get more than 7.5-8mbits. It is almost like the AP is holding back somehow. I have even tried resetting to factory default as well. I am not using WEP, just mac filtering and no broadcasting. Any other thoughts?

    My only other idea would be to upgrade the AP firmware to the latest rev.  Sorry...

    Already upgraded firmware to latest. I am going to try another AP. Thanks.
