There are times while surfing the internet when you are reading a critical article or downloading a file or streaming video online, and the speed of the internet falls or the network times out. This may often happen if your Wifi range is not adequate for proper networking. To solve this problem, the best method is to use an old router, connected with the existing one, and form a repeater or extender. Now, a Wifi repeater or extender is a device or combination of tools, used to extend the coverage area of your Wifi network. The old router, working as a repeater, receives a signal from the existing router, amplifies it, and then transmits the boosted signal, widening the network coverage area.
Before we know the configuration, we must check whether the DD-WRT router ( your existing router) is in its default settings. If not, we have to do a hard reset, removing all the current configurations from the NVRAM of the router. These steps can do this:-
- Hold the reset button located on the lower side of the router for 30 seconds. During this, the router must be plugged into the power supply.
- Next again, press and hold the reset button, now with the unplugged router, for another 30 seconds.
- Again press and hold the reset button and plug the router into the power supply for 30 seconds.
Now, your router is ready for configuration.
How to Extend your Wifi network with an Old Router
Since we don’t need Ethernet cables for a repeater, unplug it and connect to the old router wirelessly. The default SSID will be DD-WRT. For this, first, you need to set an admin username and password.
- Go to the Wireless section in Control Panel and click in Basic.
- Change Wireless Mode to Repeater Mode.
- Now, select Wireless Network Mode to match your router.
- Choose and set the SSID to match your router.
- Below Virtual Interfaces, option, click on Add.
- Now, change the SSID and set a unique one.
- Click on Save and go to the Wireless Security section.
- After opening it, go under the Physical tab Interface and check the settings to match those of the primary router.
- Now, keep both the settings of the Virtual Interface section and Physical Interface section similar. Click on Save.
- Go to the Security option and disable the SPI Firewall and remove the checkmarks from each box listed under Block WAN Requests option. Click on Save.
- At last, open Setup and select Basic Setup. Change the router IP to another subnet other than that of your primary router. Click on Apply.
After these, the router will restart, with the SSID you chose for the repeater enabled. Connect to it, and you will have a wireless repeater to extend the Wifi network using an old router.
Generally, people use 802.11g routers for a stable 54 Mbps connection. This is enhanced by its newer version 802.11n routers, giving a higher speed but with some limitations. Setting a repeater in the home, office, or inside school premises enables better network connection and availability.
