Pico phew server hangs

The server hangs for hours and will sometimes connect. How can I troubleshoot the problem. I am looking at it using wireshark and only get arp commands. For example:
84 4023.264516616 Giga-Byt_8b:7a:72 Broadcast ARP 42 Who has 192.168.86.34? Tell 192.168.86.131. 34 is my pico address and 131 is another linux machine connected to a chrome browser and looking at address 192.168.86.34
