Normally this .cache file is removed when the dhcpcd -k command is used to shut down dhcpcd . If for some reason it remains, simply remove it and run dhcpcd again. This will allow the client daemon to successfully negotiate new settings. After completing the registration process, the Web page will instruct you to reboot. Simply wait for approximately two minutes, and then have your DHCP client renew its lease as was done above to begin the process.
Network access can then continue as normal.
Make sure that these are the only DNS servers available to your machine. In general it is easier to allow the DHCP client to do this automatically, but as always there may be circumstances where manual configuration is desirable. Beyond those covered in this document, most issues will be directly related to remnant legacy settings or general network connectivity. The first of these can in general be resolved by carefully making sure that DHCP alone is used to configure your interface. As noted, resolv.conf is the normal point of resistance here, but there may be other circumstances involved.
