Cannot connect to WIFI Nighthawk AX$ AX3000 4

[JamieJammer]

Hi

Just come back from holiday and cannot connect to WIFI. Device see it, but will not connect. I cannot check if there has been a firmware up date either

Any ideas

What error are you getting when you try to connect? 

Does it connect and say "connected, no internet"?

Does it not see the wifi broadcasting at all? 

Does it see the wifi but not able to connect? 

What modem is the router connected to? 

What actual router is it? AX3000 is a speed, not a model. 

Did you try factory resetting the router?

Hi

It is a NightHAWK AX4 AX3000- Model RAX40

You can see the router on  phone but will not connect

Connected to Ethernet cable. Connected cable to my PC and worked fine

Tried factory reset with no success

You didn't answer the question from @plemans about the modem/gateway. What is it?

The first thing to try, even before going anywhere near the nuclear option of a reset, is to restart the network.

Be sure to restart your network in this sequence:

• Turn off and unplug modem.
• Turn off router and computers.
• Plug in and turn on modem. Wait 2 minutes for it to connect.
• Turn on the router and wait 2 minutes for it to connect.
• Turn on computers and rest of network.

This can unscramble the router's brain and get it to behave itself.

Hi

That did not work.,  It now says cannot get IP address when i try to connect with my phone

The modem/gataway is a virgin media one. Hub 4 /TG3492LG- VMB CM MAC ACF8CC80CA06

Any other suggestions?

That will be a modem/router. So you are piling router on router. A bad idea:

When you set up the RAX40, it will have tried to avoid any conflicts. Sadly, it doesn't always stick. Maybe something rebooted itself in your absence and screwed up the settings.

The preferred fix is to put the Virgin box into bridge (modem only) mode:

virgin media one. hub 4 bridge mode - Google Search

At least Virgin, unlike BT, does not block this mode.
