Hi Bad, It *is* specific to ad-hoc mode.  I can run in managed mode
all week no problem.

Here is a quick experiment:
on 7400:
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 channel 10
iwconfig wlan0 essid testnet
ifconfig wlan0 192.168.11.1
/sbin/udhcpd /* if need to use dhcp on laptop */
on a wifi laptop, associate with testnet and get a dhcp address (or
static)
on 7400: ping <ip address of laptop>

After about 2-8 minutes, the ping will hang.  Using dmesg you can
eventually see the timeouts.
