What you will needOver the years I've moved homes several times and changed ISPs several times too. I've acquired a number of wireless routers so I didn't have to buy a second router. This is what you'll need:
- A 2nd wireless router. I had a spare one already but if you need to buy one expect to pay about £35 for a new one or £20 second hand. Ebay and Amazon both sell them as do computer shops.
- A length of CAT 5 Ethernet cable with an Ethernet plug on each end. Get the length you need plus a little extra. These can be bought ready made, in various colours, quite cheaply on Ebay.
- Cable clips to fit your Ethernet cable.
- A short Ethernet lead (one probably came with your routers)
- A computer to change the settings with.
Position the second router
Find out some information about your current router
- The channel number the router uses. It may be set to auto. My BT router used Channel 6.
- The DHCP network range of IP addresses the router uses.
On my BT Home Hub 3 I found this by going to Settings > Advanced settings > Home network > IP Addresses. The addresses on mine were 192.168.1.64 - 192.168.1.253
Setting up the second router
- Find where you can change the router's IP address. On my D-Link I found this under Setup > Network Settings. Look at the gateway address you found and the DHCP network range of IP addresses the 1st router uses. Choose the nearest number to the Gateway IP address
My BT Home Hub 3 gateway address was 192.168.1.254
The DHCP network range of IP addresses the router used was 192.168.1.64 - 192.168.1.253
The nearest IP address was then 192.168.1.253
- On your computer open a command window and type in ping 192.168.1.253 (or whatever number was your nearest available one). IF that IP address is unused you'll see something like this:
This is exactly what you want to see. Set the second router's IP address to this value
If the IP address is already being used you'll get something like this:
If this is the case you'll have to choose a different IP address - change the last part of the number only.
- In the same area of settings (2nd router) look for DHCP server settings and disable the DHCP server
- Save the second router settings. At this point your connection to the second router will end.
- Disconnect the second router from your computer and connect it to the first router using the long Ethernet lead. Again avoid the WAN ports on both routers.
- Back on your computer, in a web page type in the new IP address you gave the second router. Again enter the username and password to access it.
- Change the Wireless Network Name (or SSID) of the 2nd router. Choose a simple to enter name but not one which contains personal information or the router type. On my D-Link router I found this under Setup > Wireless settings > Wireless network Name. I resisted the temptation to call it 'GoogleCameraCar' or 'MI5van'
- Set the Wireless security mode to WPA-Personal or WPA/WPA2
- Set the wireless access key (on D-Link routers this is called a pre-Shared key) to something cryptic, at least 10 characters long, and using both letters, numbers and symbols. Don't use a word found in a dictionary or a name. Make a note of this key!
- Set the wireless channel to be different to the one used by the first router. If you have an older Kindle don't use channel 11. The further away the channel numbers are from each other the better. I used 6 on my main router and 10 on the 2nd router.
- Save your settings again.
- Now you need to set a new administrator password for the 2nd router. On my D-Link I found this under Tools > Admin. Again set this at least 10 characters long and make it a mixture of letters, numbers and symbols. NOT 'Password', blank, your car registration, your mother's maiden name, your pet's name, your date of birth or anything else easy to guess. Make a note of this password!
- Save your settings again!
Tidy up those cables
