Subject description: puppypc daemon.info dhcpcd: eth1: carrier lost		  
Hello all,

When I first installed Puppy it successfully connected to my wireless network, but later this error suddenly appeared, and I don't know what could have caused it: " DHCP client failed to negotiate with wireless network". I didn't change any network-related settings in Puppy and neither did I modify the configuration of my wireless router.

Could you please help me troubleshoot it?

Here's the log file referred to from the window with the error message:
Code:

When this happens to me I unplug and remove the
battery from the cable modem for about a minute.

rjbrewer, that's not it: Puppy is the only one of several devices who is unable to connect to my network, so the problem is with Puppy.

When I tried configuring it using the Network Wizard, I got it working, but dhcpcd didn't start. Then I tried to start it manually and got an error message saying that the file
Code:
/etc/resolv.conf

couldn't be accessed because of a too high number of nested symbolic links. So I just deleted the file and now dhcpcd is working. Very strange.

In my case it also happens to the other machines
using the router; windows, macs, nintendo, etc.

I'm a wireless dummy.
If I ever want to start learning, I would probably start
studying posts by Tempestuous:

Thanks for the link.

This time, using the Internet Connection Wizard instead of Simple Network Setup seems to have helped.
