When DHCP server is not responding with an IP address

If the DHCP server on your network (cf. wifi, internet, ethernet) is not responding, and you're stuck with a "self-assigned IP address" and "not able to connect to the internet", one workaround that might work is to assign a static IP address that's within your network. Here's what worked on my network —

On Windows PC:

go to Control Panel > Networks Connections
double-click on the Local Area Connection (or whatever your Internet connection is named)
scroll down to Internet Protocols (TCP/IP) in the "This connection users the following items:" window
click on "Properties"

instead of "Obtain an IP address automatically", select "Use the following IP address:"
* IP Address: 192.168.130.88 [note: the last number is what's available on your network and not being used by another PC]
* Subnet Mask: 255.255.255.0 [note: depends on your network]
* Router: 192.168.130.1 [how to find router address? look at IPCONFIG of another PC that is successfully connected…]
instead of "Obtain DNS server address automatically", select "Use the following DNS server addresses:"
enter for DNS Servers (Preferred and Alternate): 8.8.8.8 and 8.8.4.4

click OK all the way out

On Mac:

go to System Preferences > Network
select Wi-Fi (or Airport) and then click "Advanced…"
select tab 'TCP/IP"

for Configure IPv4, select "Manually" and enter this info, after you find the router address:
* IPv4 Address: 192.168.130.88 [note: the last number is what's available and not being used by another PC]
* Subnet Mask: 255.255.255.0 [note: depends on your network]
* Router: 192.168.130.1 [how to find router address? look at IPCONFIG of another PC that is successfully connected…]

select tab DNS, and enter for DNS Servers: 8.8.8.8 and 8.8.4.4

click OK
click Apply
