intermittent ethernet connection problems |
Posted: Tue Oct 28, 2008 6:47 pm |

Hello,
I'm using the CCS ethernet development kit and a modified version of the web code (the LCD key controls a synthesizer and the LED key enables the system). The code will be working for a while (I can pull up the web page, control the electronics) and for no reason I can consistently replicate, the page will time out. If I reset the board, that does not necessarily fix it- so I'm not sure that this is a board or software issue. However, after a few minutes sometimes the problem goes away and it works.
The device has been set as a static IP on a router (the router DHCP range is 192.168.168.100 to 149, the device is set to 168). I did try using DHCP on the board and that might actually be helping- or I've been lucky. I have another device on the router and I haven't had problems accessing it (commercial spectrum analyzer), and I haven't had problems connecting to the network. I'm wondering if the router might be sending queries to the board which is confusing it.
The question is: what might be causing this, and more importantly, what steps can I take to actually debug this. I know that the device isn't stuck off in the weeds (I put the watch dog timer on).
Thanks,
Greg |

check to make sure the IP address is unique and not being assigned by network's DHCP server to another device _________________ Regards, Andrew

static IP shouldn't conflict |

The static IP shouldn't conflict- it's outside of the range that dynamic IP addresses are assigned. Also, the router can tell me which IP addresses have been assigned (though it won't say which static IP addresses are lurking), and of the devices on the router the two computers are assigned non-conflicting IPs and the two pieces of test equipment which are static IPs do not conflict. |

DHCP also having problems |

DHCP is also having connection issues. We can talk to it for a few minutes, it starts timing out, then we can talk to it again. How can we try to fix this?
Thanks |
