Free, browser-based diagnostic tools to test your internet speed, discover your public IP address & location, locate default router gateway addresses, and manage your WiFi extender setup.
Instantly check your public IPv4/IPv6 address, internet service provider (ISP), city, region, country, and geographic location coordinates with 1-click copy.
Measure your download throughput, upload performance, latency (ping), and jitter to diagnose WiFi dead zones and find the perfect extender position.
Lookup default IP addresses (like 192.168.1.1, 192.168.1.250, 192.168.0.254) and web domains (mywifiext.net, tplinkrepeater.net) for all router & extender models.
Complete database of factory default usernames and passwords for 27+ brands including Netgear, TP-Link, Linksys, Asus, Wavlink, Cudy, and more.
C-wire power requirements, terminal diagrams, 2.4 GHz Wi-Fi pairing guides, and troubleshooting for Nest, Ecobee, Honeywell Home, Sensi, Amazon, and Mysa.
Verify that your computer or smartphone is connected to the internet and check your public IP address and ISP details using our What is My IP tool. This confirms whether your router has an active WAN uplink.
Run the WiFi Speed Test while standing next to your primary router. Record your baseline download speed and ping. This is your maximum achievable bandwidth.
Move to the area where you plan to install your WiFi range extender (ideally halfway between router and dead zone) and run the speed test again to verify adequate signal (at least 50% baseline speed).
Connect directly to the extender's WiFi network and use our IP Address Directory or Default Logins database to configure SSIDs and encryption passwords.
Your Public IP address (e.g. 98.245.12.180) is the external address assigned to your modem or router by your Internet Service Provider (ISP). It identifies your home network to the wider internet.
Your Local IP address (e.g. 192.168.1.1 or 192.168.1.250) is a private internal address created by your router or extender DHCP server. Local IPs are only accessible within your home network and are used to open device admin settings panels.
Standard single-band and dual-band WiFi range extenders typically cut your effective bandwidth by up to 50%. This occurs because the extender must receive data from your router and re-transmit it to your device over the same wireless channels (half-duplex re-broadcasting).
To maximize speeds, use Tri-Band Mesh extenders with dedicated wireless backhauls or connect your extender to the main router via an Ethernet cable in Access Point (AP) mode.
Our tool looks up your public IP address against global geolocation routing databases (GeoIP). It maps your IP block to your Internet Service Provider's nearest regional distribution hub, identifying your city, region, country, and approximate coordinates without accessing your device's GPS hardware.
No. Public IP addresses cannot be used to log into your extender admin dashboard. You must be connected to your extender's local network (via WiFi or Ethernet) and browse to its private default gateway IP (such as 192.168.1.250) or official web URL (such as mywifiext.net).
