Wireless Issues

Why is the internal wireless signal I receive so poor?

Your wireless signal may fluctuate due to the following reasons:

Distance from your wireless router.

Signal power of your wireless router. Some routers give better coverage.

The density of walls can have an adverse effect on the distance wireless signals will travel.

Other internal wireless devices such as music systems can interfere with your wireless router signal.

Trouble Shooting Checklist

If you are encountering difficulties with your internet connection, more often than not it is something relatively simple, and in order to get you back up and running as soon as possible we have compiled this troubleshooting checklist to eliminate some common problems.

Before reporting a fault, we would encourage all of our customers to run through this troubleshooting checklist, to ensure that the cause of the problem is with the connection, and not limited to your computer, Local Area Network (LAN) or wireless router.

The old joke about ‘turning it off and on again’ is true. Often software problems and settings preventing your internet access from operating correctly can be cleared and reset by performing a restart on your computer.

For best results, it is wise to fully log out and shut down the computer and give it a good 10 seconds rest before starting it up again, but more often than not a simple restart will suffice.

Sometimes software problems can occur in any routers, access points or Ethernet hubs/switches that you may be using on your Fastcom connection, and these can be restarted in the same way by turning the power off, having a 10 second rest and turning the power back on again. Allow a good 30 seconds for the router to boot back up again before checking if your internet connection is restored.

Please note: On some routers, the reset button is not a power cycle button and will actually reset the router to its factory settings. Please ensure that you know this is not the case before performing such an operation, which should be highlighted in the manual that came with the router.

Initially it is a good idea to check that everything is actually connected properly, as it is very common for cables to be accidentally pulled out of their sockets, giving the appearance that the service it not working.

There should be a cable coming in from the main unit outside, that is plugged into a little black box, this connection is marked IDU.

Your computer or wireless router should be plugged into the opposite side of the black box and the green light should be on. If it is not, check that the power supply in plugged in and is turned on at the power socket.

There is a small black box with a single green light on, called the IDU and it is the power source for your Fastcom antenna mounted outside.

Check that the green light is on, and to restart the unit, disconnect the power cable from the unit for about 10 seconds before replacing, and also perform a manual restart on your computer to reset the settings. You can then check your internet connection once both units have restarted by trying to visit a common website like Google.com in your web browser.

If you are having difficulty with sending email, first check that your internet connection is working properly by visiting a reliable web page like Google.com in your web browser.

If you can still connect to the internet, your problem may be related to your email service or settings and you should contact your email service provider for support or access the help menu on your email application.

If you are still encountering problems and all else fails, report any difficulties that you are having to our Technical Support Team by calling 1890 71 71 71 or e-mailing support@fastcom.ie.

If you are calling outside office hours, please note all voicemails will be returned.

How to run a speed test?
Wi-Fi Router Set Up

The LAN cable left by our installer is your connection to the internet, this cable can be plugged directly into your home PC or laptop or can be plugged into a wireless router.

When plugging into a router, you must follow your router manufacturer’s instructions (usually it is a plug and play).

  1. Plug LAN cable into ‘internet’ or ‘WAN’ port on router.
  2. Turn on router.
  3. Go -> Wi-Fi setting on wireless device (laptop, smart phone).
  4. Select router name from the options available and enter the password that came with it (usually located on the bottom of the router).

My Wi-Fi cannot reach all areas of my house?

This is a common problem with large homes or homes with thick walls, it is advised to centralise the wireless router to the best of your ability but sometimes that is not enough.

There are two common ways to increase the range of your internal network:

  1. Wireless extenders/repeaters – these devices link with your main Wi-Fi router and then send the signal further. You usually have to place them somewhere central between your router and dead zone in your house.
  2. Powerline Adaptors – These come in sets of two or more devices which communicate with each other through the electrical wiring in your home. You have to place one of the plugs beside your Wi-Fi router and link it with the LAN cable. Then you can take the other Home Plug to the area where your Wi-Fi coverage is poor.
