Hi all,
I wrote a custom web server based on FreeRTOS lib for a ARM micro.
I put a couple of pages and I request them from a PC browser. Sometime (especially with a WiFi connection) I'm not able to receive the page.
I captured the network traffic and I put it here

Please, which is the problem ?
Thanks a lot !

Could you mark that capture as publicly accessible?

Ops: i'm sorry, now it should be public ..

The first full-size packet (tcp.len 1460) from the server is not getting to the client.

You can try with a ping to test which MTU size is supported on your connection and reduce the MTU size accordingly

ping–f –l 1472  (MTU size 1500) 
ping–f –l 1372  (MTU size 1400)
