FYI:
SSID: Or Service Set Identifier, is used to identify wireless networks. By displaying
a list of SSIDs in your range you can select one to connect to.
WPA2: Security protocols used to secure wireless computer networks.

Wireless networking is a great way of accessing the internet. However, due to the nature of wireless
networking and environmental influences - for example interference from other equipment or thickness of
internal walls - we cannot guarantee that wireless will work in every location.
Like radio and television waves, wireless is subject to interference from electrical sources. If you have low
signal strength, or you keep losing connection, it could be because some objects are interfering with your
router and causing ‘noise’. Your wireless signal will be the strongest when it is clear of any obstacles and is in
a clear space. Try these tips to get the best out of your wireless:

Do not place your router in an
enclosed space, such as a cupboard as
this can limit the signal. Your router
needs space and should be in your
line of sight.

as these send out radio signals which
can interfere with your router,

Keep your router away from reflec-

these objects.

A wired connection is always going
to be faster than wireless. For faster
speeds, try connecting your PC and
router with an ethernet cable and
leave Wi-Fi for your other devices.

• Most wireless routers will provide a range of approximately 100 meters. If you live in a larger property and
need greater coverage then you may need to add an additional wireless access point. If you are unsure on
how to do this we recommend you contact a local computer technician to assist.
• Your wireless performance could be slowing down due to interference from other wireless networks
in your area. Your router will automatically look for the channel with the least interference or “noise”,
however from time to time, other devices in your area could overlap onto the channel your router is
broadcasting on and will compete for the airwaves, causing the Wi-Fi to slow down. You can try and
overcome this by changing the channel/frequency that your router will communicate on. We have
provided instructions in section 4. Changing the wireless channel on how to do this.
• Try disabling your firewall software and then try to connect again. If this works then contact your firewall
supplier for more help
• Remove any old wireless networks as your router may be trying to connect to these instead of the new
one. See section 8. Removing wireless networks
• Change the Wireless Network Name (SSID) of the router and then try connecting to this newly named
network. If you are using a router not supplied by seethelight then refer to the manufacturer’s
instructions.
• Check your computer for viruses by running an anti-virus software. You can get a free trial download of
AVG anti-virus software at www.seethelight.co.uk
• And remember...wireless Encryption Keys are case sensitive
• Check the lights on your router to make sure there are no faults here. More about your routers’ lights can
be found in the internet user guide, hosted on our website at www.seethelight.co.uk
If none of the above solutions worked, we recommend connecting your PC to the router via an Ethernet
cable and check for online solutions, or getting a computer technician to look at the problem.
3. Other things to consider when connecting wirelessly

4. Changing the wireless router’s channel/frequency
Your wireless performance could be slowing down due to interference from other wireless networks in your
area.
From time to time, other devices in your area could overlap onto the channel your router is broadcasting
on and will compete for the airwaves, causing interference, or “noise” which will in turn cause the Wi-Fi to
slow down. You can try and overcome this by changing the channel/frequency that your router will com-
municate on.
Your router will automatically look for the channel with the least interference or “noise”. If your laptop/PC
is unable to “see” your Wireless Network Names (SSID), you may need to login to the router and change
the channel manually.
To change the wireless router’s channel/frequency:
1. Connect your router to your computer or laptop via an Ethernet Cable
2. Launch the wireless router’s administration webpage by typing the address http://192.168.1.254 into
your web browser. When prompted, enter the username admin and the password quick
3. Click Network on the left hand side of the screen and then click Wireless LAN on the left hand side of
the screen
4. If it is ticked already, un-tick Auto Channel Selection
5. Select a preferred value in the Channel Selection dropdown menu and apply the settings
6. Wait for confirmation that settings have been applied and then power your router o an on again
7. Wait 1 minute before scanning for the Wireless Network on your computer or laptop

There are a number of options you can select:
No security
This is not recommended by seethelight as this will allow anyone with a wireless device to connect to
your router and use your internet connection and possibly access devices and information in your home
network. This option would generally be used for fault finding & turning it to this mode is at your own risk.
WEP
This is an older version of security and although it is secure, it is the weakest of the options. This works
best with older router models.
WPA
This option is more secure than WEP and the password can be letters and numbers.
WPA2
This is the latest security standard and is the recommended security type. The password can be letters
and numbers.
To change the Encryption Type:
5. Changing the Encryption Type
1. Connect your router to your computer or laptop using an Ethernet Cable
2. Launch the wireless router’s administration webpage by typing the address http://192.168.1.254 into
your web browser. When prompted, enter the username admin and the password quick
3. Click Network on the Left side of the screen and then click Wireless LAN on the left of the screen
4. Select a new Security Mode. Selecting WEP option may require a pass number to be entered. Click
Apply
When the wireless router restarts, it will operate the new Encryption Type. You may need to delete the
wireless network from your preferred networks list, and then reconnect using the new password.
6. Changing the Wireless Network Name
The wireless network name (SSID) is the name your router shows, enabling you to see your own network
to connect. Changing the wireless name can sometimes correct or fix errors with wireless networks.
1. Connect your router to your computer or laptop using an Ethernet Cable
2. Launch the wireless router’s administration webpage by typing the address http://192.168.1.254 into
your web browser. When prompted, enter the username admin and the password quick
3. Click Network on the left side of the screen and then click Wireless LAN on the left of the screen
4. Enter your desired Wireless Network Name (SSID) in the Name (SSID)1: Box then click Apply
When the wireless router restarts, it will operate the new Wireless Network Name (SSID). You may need
to delete the wireless network from your preferred networks list, and then reconnect using the new
password.

We recommend you regularly change the Encryption key/password to help keep your wireless network
secure.
Note: The Length of the password you can use depends on the Encryption Type you have selected.
WEP ASCII : 64 bit = 5 ASCII characters
WEP ASCII : 128 Bit 13 ASCII characters
WEP Hex : Hex 64 bit = 10 hexadecimal characters “0-9 , A-F”
WEP Hex : Hex 128 bit = 26 hexadecimal characters “0-9 , A-F”
WPA-PSK & WPA2-PSK encryption recommended characters is around 8 or above “0-1 - A-Z” ,
Make it secure but easy for you to remember.
8.1 Windows XP
1. Open network connections and right click Wireless Network Connections, then click properties.
2. Under preferred networks, click the wireless network you want to remove and select “Remove”
8.2 Windows Vista
