I have a Linksys WRT54GS and have two machines on my network connecting wirelessly. DHCP is enabled, and is granting IP addresses in the .100-120 range. The one machine is a laptop running Ubuntu 10.04 and it is working via DHCP, IP address .103.

- Intranet, no Internet after switch to static IP on OS X. Ask Question Asked 8 years, 11. It's grabbing an IP address outside of the DHCP range;.13. Since I did so, the Mac can see the local network, and I can access the router config from it, but all traffic outside of my LAN is blocked for that machine. 'DHCP with manual address.
- If you configure DHCP with a manual address you have to enter the IP address you want to use. The computer will not get an IP address from the DHCP server. If the computer does not get the subnet mask, gateway address, etc. Then the router does not support this mode. You have to set either Manually or DHCP then.
The second machine, OS X 10.4, I set to a static IP in order to allow port forwarding from the router, as per these instructions: http://portforward.com/networking/static-Mac10.4.htm. It's grabbing an IP address outside of the DHCP range; .13.
Since I did so, the Mac can see the local network, and I can access the router config from it, but all traffic outside of my LAN is blocked for that machine. I see no settings indicating any sort of filter or rules that would block web access.
Where did I go wrong?
Jul 21, 2006 Airport DHCP fails to get address (Mac on Windows Network) Discussion in 'Mac Accessories. Databases, proxy server for internet etc, etc.). NOTHING with wireless connection, not even ping, even if I type in a manual IP address (valid, in-range, unused etc.). I have not tried 'reserving' a mac address on the dhcp server, I will try that. Mar 20, 2014 This occurs when the static IP doesn't take and the device (in our case, the XB1) can't retrieve a valid address from a DHCP server. If this is occurring, it suggests that either the XB1 networking configuration isn't being recognised or that the manual configuration is taken, but the XB1 defaults back to DHCP after it fails to contact the gateway.

When manually configuring the 10.4 machine, did you enter the subnet mask and the router's address correctly?
When testing off-network connectivity, did you try connecting to things by IP address or just by name? Because maybe you forgot to enter a valid DNS server address on your 10.4 client, and since it's not getting that information via DHCP anymore, it doesn't know who to ask when it needs to look up the IP address for a given hostname.
SpiffSpiffAre you trying to use the 'DHCP with Manual IP' setup available in OS X's Network system preferences? I personally have never gotten that to work properly. Make sure you're configuring TCP/IP 'Manually' and copying all of the addresses (Including DNS) from what would be distributed by DHCP except for the IP address.
Something else I would recommend, not as a fix but as an advanced alternative, would be to set up your router to do some static DHCP: distribute a predetermined IP address to the 10.4 machine based on the MAC address of its ethernet interface. You probably can't do this with the stock firmware on that router, but that router is well known in the community to be a good candidate for alternative firmware such as DD-WRT. I personally have had great success with Tomato, which is very lightweight and easy to use, while drastically expanding on the limited feature set of Linksys stock firmware.

Internet Fails When Changing To Dhcp With Manual Address Machine
1) your router might be set in a way that it hands out the .3 IP via DHCP, so another machine on the network might be using the .3 address already
2) do you have another device set up to use .3?
3) do you have set your subnetmask, routing and DNS information? those are important. subnetmask should be 255.255.255.0 and routing and DNS is the IP of your router in most cases
4) your static IP should start with either 192. or 10., is that the case?
5) if all of that doesn't help, can you access your router with the static IP (entering its IP in the browser URL field)?
edit: also, OS X has a little annoying bug where it sometimes deletes your DNS info when you switch from DHCP to manual IP. after you are done, click apply in the network settings dialog, go back to the system preferences main dialog, back into network, click advanced, switch to the DNS tab and make sure your DNS IP is present in the DNS-Servers list. if not, add it and apply the changes.
