Cisco 877W Wireless Connection Dropping Off

Hi,

I do need again your help. Sorry. I got issue with my 877w wireless connection.

Wireless connection is OK when 887w rebooted, and speed is good.
ping 10.10.10.1 get 10ms response.

Just after 1-3 minutes since rebooted, the wireless connection become terrible, either >1000ms response or just dropped off and hard to connect back, until I reboot the 887w again.

The wireless light and wireless data light seem to be just normal, one solid, one flashing.

The wired connections are all very good all the time.

below is a piece of config code:

dot11 syslog

dot11 ssid double5

Is this an 877 or 887?

Why do you have "ip nat inside" in your Dot110 interface?

Is the antenna attached?

Have you tried scanning if your wireless is interferring with someone else's?

Try IOS update.

Alos, this should post in WAN or Wireless, not SBCS. Your product is not SB.
