Hi,
We have a 3448 controlling a 160. Just recently the 160 started not allowing connected client's to access the internet/network. They receive an IP address but no traffic goes anywhere. Eventually they are disconnected (might be windows reconnecting automatically after no network access found) and reconnect just fine. Over and over without ever having access. This happens to all devices and the issue is temporarily solved by rebooting the 160. Any ideas on what/how to troubleshoot this? I've upgraded the device to the latest firmware which didn't fix the issue.
Here are the access point related configs:
interface dot11ap 1 ap-type nv16x
access-point mac-address 00:19:92:11:D1:E0
name somethingAp1
location copy_room
ip address 10.34.63.2 255.255.255.0

Upgrading to the firmware just released seems to have fixed our issues: NetVanta 160 (6.5.5-16)
After reviewing your configuration, I recommend changing the channel bandwidth and packet aggregation settings as I have shown below (also, you must apply the changes to the AP for them to take affect):
The following example enables the 20 MHz channel width on the 802.11a/n radio:
(config)# interface dot11ap 1/2 radio-type 802.11a
(config-dot11ap 1/1-an)# channel-width-20MHz
The following example disables packet-aggregation for the 802.11n clients on the 802.11b/g/n radio:
(config)# interface dot11ap 1/1 radio-type bg
(config-dot11ap 1/1-bg)# no packet-aggregation
Use the dot11ap apply-changes command to apply any configuration changes to a NetVanta 160 Series access point (AP). Any configuration that is performed on the AP is not completed until the configuration is applied to the AP using this command. Variations of this command include:
# dot11ap apply-changes all
Please, do not hesitate to reply to this post if you have any further questions or information.

Thanks Levi, I've made the changes and I'll update this post with the results!
Sincerely,
Ryan
Actually the command above 'channel-width-20MHz' didn't exist. I was able to make the changes through the GUI though...
Levi,
We still have the same issue. Here is the updated config:

I sincerely apologize, I missed your response on this post. Are you still experiencing trouble with this design? In the configuration you submitted, I do not see the channel-width-20MHz command in the "A" radio? This command was not implemented until firmware version R10.4.0. What firmware version is the wireless access controller running?

Levi,
It wasn't an option for me to set... I unchecked the use 40MHz in the web gui but that was the closest I could find. Here is the output:
