        There are so many extenders and mesh extenders models that Netgear distributes to the internet and network users. Here, we will talk about how to complete the Netgear AC750 EX6100 – new extender setup with the help of the different methods. We will also provide simple to apply troubleshooting tips to make the setup error free. 
AC750 EX6100 – New Extender Setup
There are some of the major setup methods: like mywifiext, app, & WPS, that will help you to make a choice in between which is easiest for you. 
Connection with WPS
Plug the extender in. Just find an outlet kind of halfway between your router and the dead zone you’re trying to fix. 
- The light on the side will do its usual blinking thing while it boots. Give it like a minute.
- Now, on the extender itself, there’s that big WPS button. Hit it. The WPS light should start flashing. That means it’s in “looking for a router” mode.
- Next, go to your actual router. Most modern routers have a WPS button too — sometimes on the back, sometimes on the side. Press it.
- You’ve got about two minutes after pressing the extender’s WPS button to press the routers, so don’t wander off.
- If all goes well, the extender’s WPS light should stop blinking and go solid green (sometimes amber depending on signal strength, but green = good).
- That means the handshake worked. Congrats, they’re talking to each other. At this point, the extender basically clones your existing WiFi network. 
- By default, it’ll copy the same SSID (network name) but with “_EXT” onto the end. 
Test it out. Grab your phone or laptop, walk over to the dead zone, and connect to the _EXT network. If it loads pages faster than before, you’re good.
How to Configure AC750 Extender via Interface?
- Connect your laptop, look for something like NETGEAR_EXT. No password by default. Just connect.
- Once you’re connected, open a browser and type this in the address bar: www.mywifiext.net or 192.168.1.250. One of those will load the setup page. If it doesn’t, clear your cache or just try another device.
- You’ll land on the Netgear WiFi extender setup login screen. It’ll ask you to make an admin login for the extender. Pick a username/password that you’ll remember. 
- Next, it scans for networks. This takes a minute. When your home WiFi shows up, pick it. Enter your WiFi password.
- It’ll ask if you want to extend the 2.4GHz, 5GHz, or both. Honestly, do both unless you have a reason not to.
- Give the extended networks a name. I left mine as HomeWiFi_EXT so I know which one’s the extender. 
- You could name it the same as your main WiFi if you want seamless roaming, but that can get confusing when troubleshooting.
- Hit apply. The extender reboots (takes a couple minutes).
- After it comes back, reconnect your phone/laptop to the new extended WiFi network. Test it. Load a site, run a speed test, whatever.
If it works, you’re good. If it doesn’t, unplug the thing and start over. 
How to Configure AC750 Extender via Nighthawk App?
- Download the Nighthawk app on your phone. iOS or Android, doesn’t matter. Open it, and it’ll immediately try to find the extender. 
- If it doesn’t, here’s the trick: connect your phone to the extender’s temporary WiFi first. It’ll show up as something like NETGEAR_EXT in your WiFi list. No password at this stage.
- Once you’re on that, flip back to the Nighthawk app. It should suddenly “see” the extender and kick off setup. Follow the prompts. 
- You’ll pick your main WiFi network, punch in your actual router password, and then it creates a clone network. Usually adds “_EXT” to the name, unless you rename it.
Troubleshooting Tips 
- If you bought it used, or even if you messed with it before and gave up—just hold that reset pin in with a paperclip for like 10 seconds. Watch the power light blink. Trust me, starting fresh saves you from chasing weird leftover settings.
- Push the button on the router, push the button on the extender. In reality, half the time it either fails or connects to the wrong band. If it works for you, cool. If not, skip it and go manual.
- If the extender is too far from your main router, it’ll still “connect” but crawl. Place it closer than you think you need to, then walk around with your phone and test the signal.
- Firmware updates. Go into the extender settings and check for firmware updates. Old firmware causes random drops. New firmware doesn’t fix everything, but it helps.
- When all else fails… Ethernet. If you can connect a cable to it, the EX6100 can act like an access point instead of just a repeater. 
Hope these setup instructions and troubleshooting guide have helped to complete the AC750 EX6100 – New Extender Setup in minutes.
