I have numerous 802.11b cards that will not see the wireless network but 802.11g see it fine. I have set it up per the directions to make the 1.0, 2.0, 5.5, and 11.0 as the basic rate. What else do I need to do? Thank you for your help.

That should be all you need to do. Also, make sure you're not using WPA with AES for encryption, as most b-cards won't support this.
At this point you need to isolate whether it's a problem with the access point or a problem with the cards. See if you can find another access point or wireless router, and see if the b-cards can connect.
If you can post your configuration, that would probably help us troubleshoot.

I am not useing WPA. The cards can access other access points. Here is my config file and thank you for all of your help:

Try the following in config mode:
dot0
channel 1
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
See if that works. For some reason this configuration is missing under dot11Radio0. Feel free to use a channel other than 1 if desired.
10-10-2008 07:08 AM
I am sorry to ask this but I am a point and click guy. To perform what you want me to do I will need to log into the device through a Telnet session right? Then once logged in I type config and then start typing one line at a time and enter after each one? Sorry for the neophyte questions but I am not a strong Cisco guy.
10-14-2008 12:04 AM
It might be that Your old cards dont support short preamble.
Try disabling short preamble for the 802.11b radio from the GUI or from the CLI:
Step 1
configure terminal
Step 2
interface dot11radio 0
Step 3
no preamble-short
Step 4
end
Step 5
copy running-config startup-config
Short preambles are enabled by default.
10-14-2008 03:34 AM
Thank you. I will try that and post my results.
10-14-2008 05:13 AM
Sorry for not responding for several days, I somehow missed that you had responded. Disabling short preamble is a good idea as well.
When you log in, you actually type "config t", t being short for terminal. Let me know how it goes!
10-14-2008 10:56 AM
No problem at all. I tried what sanamon suggested but it did not work. When trying to type the first line of yours I would get an error after the dot0. The error is invalad entry pointed at the 0. Below is my config file now. Thank you for your help.

That's totally my fault. The command line should read "int dot0". I must have been sleepy when writing that out :D
10-14-2008 12:48 PM
I input the info as you suggested unfortunatly it still does not work. I will paste my config agian but I do not see you had me configure. Do I need to do something to save the config? Thank you so much for your help.

Are You sure the old cards support 128bit WEP? Some cards only supported 48/64 Bit WEP (such as the Orinoco silver cards etc)
From the config I can see that long preambles are now configured.
10-15-2008 03:52 AM
Yes. They were connected to an Aironet 1200 series with 128bit WEP before it died. I really apperciate your help.
10-15-2008 05:00 AM
Are your clients configured with the wep key on index 1 and not on 2,3, or 4? So even with an ssid that has no encryption at all, your clients still can't connect?
10-15-2008 11:13 AM
That was a good question and yes they are configured on index 1. I am just going to get the users new wireless cards. I have already put more time in this than the cost of the new cards. Thank everyone for all of your help. How do I need to close this thread.
