Once you have located your ISP router, you should see some login credentials on it. It may be labelled as admin settings, or admin address, or something of that sort.
I have Telus as my ISP and this is the router they supplied. On the device you can see the admin settings IP.
This is probably the easiest way of finder the admin address or technically “default gateway address”. If the router does not give you this address, that’s ok — there is another easy way of finding it.
Firstly, make sure you are actually connected to the network you are wanting to change. The easiest way to do this is take an ethernet cable and directly connect to the router. I know some laptops have done away with the ethernet port in the interest of saving space. In this case I recommend getting a USB to Ethernet Port Adapter.
Alternatively you can connect to the WiFi network wirelessly but in the interest of robustness I do recommend the hardwire method.
If you are on a Windows machine hit the windows + R key to get the run command window. Next type in cmd to get the command prompt. Then type in ipconfig into the command window and hit enter. Look for the label “Default Gateway”, next to it you’ll see an IP address. You may have two line entries next to default gateway. The top one is IPv6 address (contains numbers and letters and is long) and the bottom is the IPv4 address we want (contains only numbers and three periods).
After entering the ipconfig command look for the default gateway label and the IPv4 address.
If you are using a Mac the command will be slightly different. First launch the terminal app by pressing command + space bar on your mac keyboard. Next type in Terminal in the search and click the Terminal utility in the search results. Next enter the command: route get default | grep gateway
Using the route get default | grep gateway command, we get the gateway address.
You will now see the IPv4 gateway address we need to log into the router.
Yes, it’s even possible to change your WiFi network name and password via your phone. Again, I much prefer being directly connected to the router via an ethernet cable — but I know that sometimes isn’t feasible for everyone.
On an android phone go to Settings > Connections > Wifi > Connect to your WiFi and click the gear icon next to it once connected > Click Manage Router. You’ll see the gateway address in the browser address bar that pops up.
On an iOS device go to Settings > Wi-Fi and tap the small (i) next to the network you’re connected to. Next to Router is the default gateway.
