Region : India

Model : TD-W8151N

Hardware Version : V3

Firmware Version :

ISP : BSNL India

Not able to connect Google Chromecast to TD-8151N.
In Chromecast website troubleshooting tips, they suggest the following:
1. Disable access point isolation (also known as client isolation or guest mode) - I cant find this anywhere in 8151N
2. Enable UPnP - done
3. Enable IGMP - There are 3 versions of IGMP. I have tried with v1 and v2. Didnt help.

Not sure where is the problem. My chromecast just done connect.
Please help
thanks
