Please post a capture file of the non-working scenario and I'll try to help with the networking stuff. Try to actually describe what you have and what you do in terms of lwIP API function calls, some of us don't have a clue on vendor kits. If you are "getting the IP address of the PC", either the server is nuts or the "bridge" is not bridging but masquerading, acting as a proxy and sending your requests as his. You should be able to know what it does and configure it accordingly. If it bridges, your MAC goes out on your request and you get assigned an IP. If it masquerades, usually that also means different IP networks, routing. You either run your own DHCP server on your internal interface or assign fixed addresses. What is a TP-Link access point in 'client' mode ? Is it a wireless bridge ? Have you captured traffic in both ends to actually known what is going on and why it is notr working ? The most efficient way to solve networking problems is by looking at network traffic (after checking the socket light, the cable is in the socket, and issuing a couple pings...)
