WPS DISCONNECT ISSUE

[anjalik at iwavesystems.com]

Hi,

  I was using Cisco router Model WRT120N. With this router,the  
disconnect issue happens . I tried with Cisco Router Model E200 , now  
the issue seems to be gone .I am able to ping but have some issue in  
the Android upper layer in updating the status as "CONNECTED". This  
issue is completely out of topic here i guess.

After changing the router the connection and pinging are working fine  
as far as now.

Thanks & Regards,
Anjali
