I have weird situation here, I cant figure out what could be the cause of this. So, my W5100 device is connected to local ethernet switch, which is connected to the wifi router.
I can telnet to w5100 from my PC connected to either wifi or ethernet, but cannot connect from mobile phone wifi. But my phone can connect to PC tcp server. Also my phone connects to the wifi<->uart chip without problems.
I cannot see anything on wireshark cause I guess packet is rejected or something… Now i dont know if the problem is with MTU settings on the router, w5100 or something else.
Anyone have idea what could be the cause of this ?
