Fix WiFi instability/intermittent behavior in connecting to the Internet, GRHub nodes and other devices.

 


I have a home fiber Internet installation, running into a modified Mikrotik HAP Lite router. (above) Unfortunately this router is a distance away from my shack and I experienced WiFi instability in connecting to the Internet at times.  This also resulted in instability/intermittent behavior when connecting to both GRHub nodes via DDNS and other clients.  This caused a lot of frustration and unable to connect issues as well as core dump errors.  Now I can ask my service provider to move the fiber installation closer to my shack but that would mean extra costs but also WiFi instability/intermittent behavour to other areas of my house.  I can also buy a new more powerful router or fit an external beam antenna to the Mikrotik router.  So I do have a few possibility.   However I had a few old Modem/Routers lying around doing nothing.  Now why buy a new router if I can use one of  the old routers.  I opted for the TP Link  TD-W8960N, not the best but it will have to do the trick here. (below)

Here is how I linked the Mikrotik and TP Link to solve my instability problem only costing me a few "bucks" for the LAN cable.

MODEM/ROUTER SETUP GUIDE: LINK TP LINK TD-W8960N ROUTER TO THE MAIN HOUSE INTERNET ROUTER (MIKROTIK hAP LITE) VIA LAN CABLE

Log into the W8960N Router with 192.168.1.1 default IP address:

First connect all the cables, power and LAN cables. LAN cable from PC to Eithernet port of the TD-W8960N Router. Power cable to Router but do not switch the router on. First switch the PC on and after boot-up open Network and Sharing Centre. Your basic network information and setup connections will show up in a new window. Click on Local Area Network and status window will show up. Select properties and then click on Internet Protocol v4 or v6 whichever is selected. Click on properties and an Internet Protocol (v4 or v6) will open giving you the option in the general tag to select either auto or use the following IP. Select “Use the following IP address”. Now enter an ip address that is the same as the routers. I used 192.168.1.50 Now click on the subnet blog and it will be filled with the required sub-net. Default gateway will be 192.168.1.1 Click OK and then Close and again Close. Now restart the PC. After reboot open a terminal screen and type ipconfig and hit enter. Your selected IP 192.168.1.50 will be displayed. Close the terminal and open an internet browser window. Enter the TD-W8960N default IP address (192.168.1.1) into the address bar. Hit enter and you will see the login pop-up window. The default username and password is admin.

Go to Wireless-->Basic/Security to change the SSID and Wireless Network Key to whatever you like, then click on Save button on the bottom. Ensure you write this info down as you will need it to connect via wireless to the TPLink Router.

Go to Advanced Setup-->Lan-->IPv4 Lan Configure to change the IP address to the one with the same subnet but different IP address from your main router, then choose Disable DHCP sever, click on Save. Note: Nonot the same as your router's IP address.
For example, if your router has an IP address 192.168.88.1, then the IP addresses with the same subnet are 192.168.88.2-192.168.88.254. Write this new IP down as this will be the new access IP to your TPLink router’s configuration/setup. The TD-W8960 can use anyone among 192.168.88.2-192.168.88.254. SubNet: 255.255.255.0 Click Save/Apply.

Now we need to change the default password. Click Management->Access Control->Password on left page, and type the old password (admin) and new password. (Whatever you choose) Click Save/Apply. Now plug the main internet router (Mikrotik) LAN cable to one of the LAN ports of the TP-Link modem.

Nearly done. Before Reboot we need to select Obtain an IP address automatically. Again open Network and Sharing Centre. Your basic network information and setup connections will show up in a new window. Click on Local Area Network and status window will show up. Select properties and then click on Internet Protocol v4 or v6 whichever is selected. Click on properties and an Internet Protocol (v4 or v6) will open giving you the option in the general tag to select either auto or use the following IP. Select Obtain an IP address automatically. Click OK and then Close and again Close. Now restart/reboot the PC as well as both routers. When the TPLink router comes back up, it will have the IP address you configured. As long as the Mikrotik Router has Internet access, the TPLink Router will now also be online with an Internet connection. Remember anytime you connect a computer to a new network device, it's a good idea to restart/reboot your computer and also the router/s.

Connect other computers and devices. This can be done wirelessly, or by connecting Ethernet cables to unused LAN ports on either router. The Mikrotik Router’s DHCP server will automatically assign each device its own IP address in the same subnet.

Gone are the WiFi instability/intermittent behavior and I can now access the GRHub nodes and other devices "cleanly".   Yes at a slower speed (100mbps) but who cares, it is now working !!

I am aware of other options that I could have followed but I used what I had on hand.
