Slow connection with Cisco Aironet 1040

justinregan — Sun, 04 Jul 2021 06:03:42 GMT

I have been racking my brain for a while and cannot figure out why I am not getting 144Mbps out of my Aironet 1040. I was reading a previous thread (

https://supportforums.cisco.com/thread/2141961) and set it up exactly like it said. I have set the encryption to Cipher AES CCMP and set the SSID to open authentication. I also set the SSID's key management to enable WPA (WPAv2).

I was reading that WMM has to be set. I have 3 options: Disabled, Legacy, and dot11d. If i chose dot11d I have to put in a coutry code. Problem is there are no options in the country code pull down. I cannot even manually type it in.

Another problem is that cell phones cannot connect. It keeps saying authentication fails in the log.

Any reason why I am having such slow speeds?

WMM is enabled by default, or at least it should be.

What type of client are you using? Check the specs of the WNIC, and see how many spatial streams that it supports.

That seems to have done it. Right now I am about 50 feet away from the AP and I am getting 58Mpbs. When I get closer to it it increases and does go up to 144.

Now my last question is why cant my wireless device connect? I haven a iPhone 5. I took a screen shot of my wireless interface. Do I have something selected wrong?

have you tried after removing the dot1h command? Some devices can't connect when that is enabled.

It tries to connect. I dont get the error anymore since we made that change, it just doesnt pull an address. It just keeps spinning.

I've had that happen with my phone as well. A few pops in and out of the WiFi and it usually picks up.
