"Oh No, My Internet is Down!"
A computer network is a complex organism, and its functionality depends on many components and systems. Occasionally any of these can fail. When this happens, we're interested in restoring the network as quickly possible -- probably as interested as you are.
In the interest of this, we've put together this document based on all our experience so far. Over half of our support calls are solved by the few simple steps outlined below. More often than not, you'll be able to restore network connectivity quickly and easily on your own.
Make sure it's plugged in
Believe it or not, the most common problem we see is that the client's equipment has simply gotten unplugged - by accident, or by someone looking for a place to plug something else in. Make sure the AC adapter that powers the antenna gear outside (see below) is plugged into an AC outlet or power-strip (and that the power strip is on). If you have a router, make sure that's plugged in, too.
Power-cycle your antenna equipment.
The most common problem seems to be a lock-up of the piece of equipment that translates your network traffic into radio signals. For most customers, this equipment is outside the house in or near the antenna. This gear gets it's power from inside the house, via a power-over-ethernet (PoE) adapter. It has 2 network plugs and one power plug, and is located near where the wire from the antenna enters your house.
To power-cycle you antenna gear: unplug the round power plug from the PoE adapter, wait a few moments, and then plug it back in. Alternately, you can unplug the AC adapter at the other end of the power plug from the wall, wait, and plug it back in. Just make sure you are unplugging/replugging the right one! Often there is more than one AC adapter.
Power-cycle your router
Customers with a router should power-cycle the router AFTER the antenna gear. To power-cycle a router: unplug the round power plug from the back, it, wait a few moments, and plug it back in.
Restart your computer
Unfortunately, today's most popular operating systems (while feature-rich) are not as reliable as they could be. Often network connectivity issues can be solved simply by rebooting the computer.
Of course, sometimes network problems aren't solved by any of the steps above. In these cases, it's almost certainly time to call us. When you do call, our support will be quickest and most effective if you have a few bits of information ready. The following things are what we will almost always want to know first, as soon as we're on the phone with you:
Make sure your antenna is still attached to the house, and is aiming in the right general direction.
If you have a router, note if the WAN or INTERNET light is lit. It should be; if it isn't, it indicates that your router isn't sensing the network link to the antenna gear. This can be a due to cable problem, loss of power to the antenna gear, a zapped Internet port on the router, and many other things. You might be able to get the Internet light to come back on by simply making sure all network cables are tightly plugged in.
For some clients (those with older equipment), your router's (or computer's, if you don't have a router) network MAC address (a unique identifier address) needs to be in our system in order for it to function on our network. If you have gotten a new computer or router, we will need the new address before it will work. But this only applies to some clients.
Did the outage coincide with any weather events, like thunderstorms, heavy rain, or snow?
For Advanced Users
If you are feeling adventurous and are comfortable with computers, there are a few more complicated things you can try.
Confirm your computer's network settings
Your computer's network card ("Local Area Connection" in Windows-speak, "Built-in Ethernet" in Mac-speak) should be set to use "DHCP", or "Get Address Automatically".
(DHCP stands for "Dynamic Host Configuration Protocol". This is a method for configuring a computer's network settings over the network. It allows your computer to obtain it's address and other critical network settings automatically from Nedernet's servers so that you don't have to be responsible for keeping track of all these settings yourself.)
You can check to see if your computer is getting it's address:
Windows XP/2000: Start Menu->Run->type in "cmd", his enter, then in the window at the prompt, type "ipconfig" and hit enter.
Mac: System Settings->Network->Show: Built-in Ethernet, under "TCP/IP"
Your IP address should be 192.168.x.y (where x is usually 0,1, 2, or 100, and y is 2 to 254) or 10.x.x.x (where x is anything 1-255). If it is 169.x.x.x, 0.0.0.0, or anything else, there is something wrong. Power-cycle everything. Make sure all cables are plugged in firmly.
Forcing DHCP renewal
You can try to force your computer to renew it's IP address.
Windows XP/2000: Start Menu->Run->type in "cmd", his enter, then in the window at the prompt, type "ipconfig /release" and hit enter. Then type " ipconfig /renew" and hit enter.
Mac: System Settings->Network->Show: Built-in Ethernet, under "TCP/IP", hit the "DHCP Renew" button.
If it comes back and shows a 192.168.x.x address, your Internet should be working (if not, there may still be a problem with the antenna gear) . If is returns zeros or a 169.x.x.x address, something is still wrong with your router or the antenna gear.
