You are a cable modem or xDSL customer, and cannot acquire a DHCP address from your provider. In addition, You have checked all the common problems regarding DHCP client setup, as documented in the support article Client configuration of DHCP, but you still do not receive a leased DHCP address from your cable modem or xDSL provider.
Some broadband providers have particular requirements of the DHCP client, or particular quirks in their configuration of their DHCP servers. These will be listed, by provider (and region) below.
Please note that this list is far from complete. If you have helpful information to provide regarding the necessary steps for acquiring addresses or getting on line with a specific cable modem provider, please send it to dhcp-tips@suse.com. Please note that this is not a support address, and all support requests sent to the dhcp-tips address will be deleted. Support requests regarding installation, setup, and troubleshooting must be sent to isupport@suse.com with a valid registration code from the manual.
@Home networks have a history of leaving their IP addresses unchanged for long periods of time. For this reason, some people find it more convenient to avoid DHCP altogether, and simply statically configure their addresses. This SDB author had been doing this for some time before asking for details from @Home. However, @Home does not guarantee a consistent IP address, and has renumbered from time to time. A correct DHCP configuration will allow this to occur with a minimum of trouble.
Setting up DHCP for @Home:
nslookup <IP-address>where <IP-address> represents the IP address assigned, to your machine, such as 192.168.0.5 . This should return an address such as c123456789-a.somewhere.ab.home.com. The first section, c12345879-a is your Computer Name. Note that successive IP addresses on a given account will be named -b, -c, etc. Thus, the the fifth such address would be named c12345789-e.
send dhcp-client-identifier "c123456789-a";where your own Computer Name is entered into this field.
