ENC28J60 + M430G2553: Build an http server with uip to solve the problem of "access is allowed under Windows XP and cannot be accessed under Windows 7". enc28j60uip

Recently, a simple HTTP server was built on M430G2553 using ENC28J60. It was found that the server can be accessed under the XP system and cannot be accessed under Win7, which is a very strange problem.

Packet capture, for example, the computer (IP Address: 192.168.1.104) does not add Checksum information to the TCP packet initiated by the server (IP Address: 192.168.1.150.

The preceding problem causes the TCP packet to be discarded directly in the uip, such.

To adapt to the default Win7 system settings, you can only modify the uip so that it does not perform Checksum and comment out the process.
