Hi,

I have an issue where clients connecting on the 2.4Ghz band can't see the internet. In particular I have a Sony vaio that connects, receives an IP and cant see internet. It's an old laptop. 5Ghz band is functioning correctly for other devices. Any help on this would be appreciated. Wondering if theres any legacy setting that I'm missing.

Hello,

        The configuration checks out, though we have seen issues with wireless clients and mix-mode encryption, which both WLANs have enabled. Not sure what the legacy 2.4GHz clients support, but if everything supports WPA2/CCMP/AES, I would configure encryption type as "encryption-type ccmp". If the legacy wireless clients only support WPA (TKIP), which has been long deprecated, I would modify the 2.4GHz WLAN with the following:

wpa-wpa2 exclude-wpa2-tkip (Exclude the WPA2 version of TKIP, support only WPA-TKIP). 

Only WPA-TKIP legacy clients would be able to auth/assoc to WLAN (not WPA2-CCMP). 

I also see that Smart-rf is being utilized for channel/power. Smart-rf only works with 3 or more APs in the environment and highly recommend statically assigning channel/power to the radios based on what is around the AP (use a freeware scan tool to see channels and power of neighboring APs). 

If issue is still persistent after making the above mods, I would get logging enabled on the AP, in order that we can see why the wireless clients are failing. 

Thanks,

Chris Frazee

Can you please provide a copy of the startup-config? Also ensure that the version of firmware is provided as well. There should be no additional configuration required for 2.4GHz.

Hi Chris thanks for picking this up. The config above is from a fresh setup which was tested and doesn't accept any 2.4Ghz clients.
