Wireless client fails to connect (iHealth)

Sun Mar 23, 2014 8:55 am

Greetings,

I experience a very strange problem: My Mikrotik runs very smoothly for several years now but one of my wireless clients (namely an iHealth wireless scale) fails to operate properly in the WiFi network. It seems to join the network without problems but can't transmit or receive any traffic. I've switched on the wireless debugging and here's how it looks:
2014-03-23T10:35:56.558722+04:00 wireless,debug wlan1 - - - wlan1: 00:1D:C9:13:61:99 attempts to associate

Looks like the client fails to negotiate the group keys. The network is an WPA2-PSK/AES and it serves a lot of other devices (several different Androids, several Apple devices, a couple of PCs). The wireless config is :
[admin@MikroTik] /interface wireless> print                  
Flags: X - disabled, R - running 
 0  R name="wlan1" mtu=1500 mac-address=D4:CA:6D:26:E3:29 arp=enabled interface-type=Atheros AR92xx mode=ap-bridge ssid="8-2-1"

     radius-mac-caching=disabled group-key-update=5m management-protection=disabled management-protection-key="" 

I've checked with a pocket 4G/WiFi router that it's not the client's problem as it connected and worked properly with the same security level (the pocket router was providing a WPA2-PSK/AES network too). I'm running the 6.11 SW on the router

Can anyone suggest a way out of this or steps to further debug the issue?

Regards,
Alex

UPDATE:

Just reconfigured my Mikrotik to provide a WEP network. The results are exactly the same -- the client joins the network, gets the IP address and then fails to communicate completely -- no pings.

Please help

Did you ever find a solution to this? I am having issues getting my scale to find the iOS app as well.

I bought a DLink AP and hooked it up to my 2011 router and the iHealth scale works fine so it is certainly something with the wireless in the 2011.
