Re static mode, just checking that this is on the X7 Ultimate, not your modem/router, yes?
In case you don't often get a chance to play with your device, I'll go ahead with some basic instructions now.
First check your modem/router's IP address and your laptop's. (Internal, not your ISP-assigned IP address).
It will probably be something like
192.168.1.1 (for modem/router) and 192.168.1.2 (that 2 could be anything from 2 to 255)
OR
192.168.0.1 (for modem/router) and 192.168.0.2 (that 2 could be anything from 2 to 255) - basically just a change from 1 to 0 in the third number of the IP address.
Now head to the DHCP/Manual area of network settings on your X7 Ultimate, and enter the following (the order and precise labelling could be different depending on your firmware revision)
GATEWAY: 192.168.1.1 (IF YOUR MODEM/ROUTER is actually 192.168.0.1 , use that instead)
SUBNET MASK: 255.255.255.0 (if you're not asked this, it may have prefilled Network Prefix Length with 24, leave that as it is)
IP ADDRESS: 192.168.1.250 (IF YOUR MODEM/ROUTER was 192.168.0.1 then use 192.168.1.250)
DNS1 and DNS2: You can decide which DNS settings to use. Some people enter just their modem/router's IP address (192.168.1.1 or 192.168.0.1) and let the modem/router farm out DNS requests correctly to the actually DNS servers (your ISPs).
Or you can look up your ISP's primary and secondary DNS servers and enter these. OR...
You can use a 3rd party's DNS servers. Most people would either go with Google or OpenDNS.
Google's primary= 8.8.8.8 and their secondary is 8.8.4.4 .
OpenDNS primary= 208.67.220.220 and secondary = 208.67.222.222 .
Please note:
There is the outside chance that instead of 192.168.1.x or 192.168.0.x your home network is based on a different range, or that your modem/router isn't 192.168.0.1 or 192.168.1.1 , but those addresses cover 99% of default setups on home networks.
Also, using 192.168.x.250 is being a bit lazy/naughty, as we should really set up the X7's IP address in your modem/router as static, and remove it from the DHCP pool. However, unless you've got hundreds of devices connected to your home network, a clash isn't likely to occur.
