Are you able to access the Internet over wired connection via the router? Are you able to access its management console using the default username and password (or your own password ***** you have changed the default one)?
Okay first double check if below link is the product you have.
> Yes on 1 wired device I can
You mean you can access Internet over wired connection from a device of you, correct?
> I use the preset wireless settings username and password ***** set up
You mean you just unboxed the device, and there are preset username and password ***** the device or wireless password (no username) only?
Great, let me check the details and get back to you soon.
Okay, please see attached the screenshot of part of the device's installation guide. I guess you have seen the Wi-Fi network name and password ***** on the product label. If so, are you able to see the given network name (SSID) from the wireless network list on your device?
Again, please confirm this question:
> I am on the internet with one of them.
Not bad, that's a good starting point.
Now from that Internet connected computer, open your web browser, type "www.routerlogin.net" in the address bar and press ENTER to access the router's management console. Once asked for username and password, type "admin" and "password" respectively. Once logged in, let me know.
Again, please let me know:
If so, are you able to see the given network name (SSID) from the wireless network list on your device?
> I have tried that but I get a message that says you are not connected to your router's Wi-Fi network.
I know you are not connected to the Wireless network, but I want to know if you can see the given network name (SSID) from the network list. The SSID is given on the product label as mentioned above. This will tell me if the router's wireless is working or not.
> To access the router login.net your device must be connected to your router's Wi-Fi network check your current connection and try again.
That's a bit weird. Can you please show me a screenshot telling what the exact error message you got in your browser?
This means you really need to login at 192.168.1.1 or www.routerlogin.net to check if any settings is wrong. Please do this on that Internet connected computer.
If it is really difficult for you to manage the things like accessing the router's console and adjusting the settings, I may offer remote assistance service at your cost ($39). That way we may share the same screen and speak over the phone, and I may help you get things done remotely and directly.
FYI - the remote assistance is 100% guaranteed. If the things can't be done, you will receive the full refund.
If you think you can handle the router settings with my guide and do prefer chatting here at Q&A page, I am happy to help this way as well. Be aware, it might be lengthy, as I can't see what happens your side and your description might be missing some key details I need.
> I think I have some kind of IP address conflict.
Your computer is not using DHCP (Automatic IP address)?
> cannot access any of them to control the router.
Not sure what you mean. Can you successfully log in at 192.168.1.1 using the default username and password?
> No. I get s message that says this page can't be displayed.
From that Internet connected, wired computer?
> One of The suggested ones does go to my modem but none go to my router
Your modem? This is the first time to mention that. What's model of it? It should be normally staying before your router and can't be "seen" by your computer directly. Does your network look like below?
Internet <-> Modem <-> AC 1900 Router <-> Your computer
Okay, thanks for the confirmation.
Now I need to know your computer's internal IP address. What's the operating system running on that Internet connected computer?
Okay, it seems you are technical, so let me explain why somethings are unusual here.
If you do mean you can see your modem's web page from your computer (192.168.1.5) when accessing 192.168.1.1, that means you are on the same subnet of where your modem stays. That means your new router is not properly connected, or specifically its Internet port (yellow) is not connected. I guess probably your modem's LAN port is connected to one of your new router's four LAN ports. Please check.
Moreover, as the new your router's Internet port is not connected, none of your wireless device can access the Internet even correct password ***** *****
Just make it clearly: you need to use a wired cable to connect your modem's LAN port and the new router's Internet port (yellow one).
You mean, after resetting the new router, everything works fine as expected now?
Good to know that. Is there anything else that I could help with?
Just double check the status, your Nighthawk AC 1900 smart Wi-Fi router works well now?
As your laptop is connected now, please kindly accept my helpful suggestions as the answer and close this question. Thanks.
