How can I setup Trendnet [TEW-652BRP] behind PTCL AZTECH router

I have a router TRENDNET -> TEW-652BRP. My computers are connected with TRENDNET wirelessly.

I want to connect TRENDNET with PTCL provided AZTECH router [DSL1000EW(L)] . PTCL router is in my friend's home and I can connect AZTECH only wirelessly. TRENDNET router provide wireless connecivity, but Iam unable to connect AZTECH and TRENDNET to access internet. Can some one guide me in this regards.
