T: Do you have an extender router that is not used? The router at home is broken.

S: Wireless router or what do you mean?

T : bla bla bla bla bla …

It turned out that he needed  an additional router to connect to the internet from the main router  because he router was currently using was broken. After I checked in the warehouse, I found the TP-Link TD-W8101G router modem.

For this guide, it’s similar to the one I’ve made before here, so it’s just a different router and this time I’ve made it a bit detailed enough to make it easier.

Here is  the default  information of  the router:

IP: 192.168.1.1

Username : admin

Password : admin

SSID : TP-Link_XXXXX (XXXXX is usually the MAC Address of the TP-Link, in this case what I have is TP-LINK_E72C6C), so it can be adjusted from the sticker attached to the bottom of the modem.

For the final topology as follows but when doing this guide I am using a PC, so just connect the LAN cable  to the PC and modem (like in the red box), do not connect to a network that is already running as it will cause looping.

Here is the guide :

1. Because this router has not been used for a long time, I will immediately reset it by pressing  the reset button between the power port and the LAN port for 5-10 seconds.

2. If the reset is successful, then when you type IP 192.168.1.1 on the browser it will be the following image, type admin in the Username and Password  column and then click Sign in.

and I check the IP on the PC will get the following.

3. Once opened, it will be directed to the Status tab.

4. Click the Interface Setup – Wireless tab. You can change the SSID according to the name you want, but in this example I will only provide a password, here is the information and then click SAVE :

Authentication Type = WPA-PSK/WPA2-PSK

Encryption = TKIP/AES

Pre-Shared Key = wireless password

5. I will replace the default IP with  an empty IP, in case I change from 192.168.1.1 to 192.168.2.5 and turn off the DHCP (Disable) feature because DHCP is already provided from the router before, then click SAVE.

Note: The IP that will be given must be the same as the IP block that is already running, otherwise you will not be able to connect to the internet.

6. Click OK if the following confirmation appears.

7. If I refresh (press F5 on the keyboard) the page will likely look like this (I’m using the Firefox browser, the error will be different if you’re using a different browser).

8. Unplug  the LAN  cable from  the PC and connect it to the previous router, as well as for the TP-Link TD-W8101G router modem (as in the topology). If true, then when we type IP 192.168.2.5 on the browser the following image will appear.

and I check the IP on the PC will get the following.

9. If you are logged in, then the IP has changed.

10. The following are the results of the test using a laptop and cellphone.

To be honest, the results are not very satisfactory because they are very far from the available bandwidth, which is 50 Mbps, here are the test results from cellphones using the same frequency, namely 2.4 Ghz, the results are better for downloading.

Finally, hopefully this article can help take advantage of unused routers, hehehe, thank you and have a nice day.

Technology is increasingly developing over time, such as ADSL technology which is increasingly being replaced by fiber optic media because it provides much faster bandwidth. For me, customers who have used ADSL modems and have now switched to fiber, of course, still have the “historical legacy” of the ADSL modem.

Can ADSL modems still be used? Of course yes, if you still have an ADSL modem that is still functioning properly, don’t rush to store it in a warehouse, because it can still be used. The ADSL modem I am referring to is a modem that has wireless features, which will be used as an additional medium to expand the wifi signal area in my home.

The ADSL modem I have is a D-Link DSL-2730E, which was manufactured around 2013. To shorten the time, here is the topology and guide I have created.

Final Topology

1. I reset the modem to the original configuration, simply press the reset button for about 5-10 seconds and release it when the indicator light flashes. Here’s the initial look after logging in with the default IP 192.168.1.1 with the same login and password, namely admin. Here’s what Device Info and WAN Status look like.

2. To change the SSID, select SETUP – Wireless Setup – Wireless Basics, but I won’t change the SSID, just change the Band mode to 2.4 Ghz (B+G+N), then click Apply Changes. Why did I choose the 3 codes? Because the internet speed I am currently trying is only 10 Mbps.

3. Next, select SETUP – Wireless Setup – Wireless Security to provide the wireless password in the Pre-Shared Key column, then click Apply Changes.

4. The modem’s default IP is 192.168.1.1, however this IP has already been used by my primary router, for which I will change it to 192.168.1.100. Actually, I can freely change to any IP, it can be equated with an existing network or a different one, but because I want to be able to remote the modem, I equate it with the existing network and the IP that is not being used, then click Apply Changes.

5. For DHCP I disable it, since DHCP is already provisioned from the main router, select SETUP – Local Network – DHCP Server, select None in DHCP Mode, then click Apply Changes.

6. To view the connected wireless devices, select STATUS – Wireless Clients.

7. Here are the results of the tests I conducted from a smart phone device.

Basically, this method can also be applied to other ADSL modems, maybe only the method is different, if there is a chance I will try it for other ADSL modem devices. Thanks.
