Ralf2, Thank you for posting in the Intel® Communities Support.

In order for us to provide the most accurate assistance on this scenario, we just wanted to confirm a few details about your system:

What is the complete model of the laptop?

Is this a new computer?

When did you purchase it?

When did you buy the Spectrum Router/Modem?

What is the precise model of the Router?

Did the wireless connection ever work fine with this new Router/Modem?

Is there any particular reason why you replaced the Router/Modem?

Did you make any recent hardware/software changes, besides installing the new Router/Modem, that might cause this issue?

The wireless card, did you purchase it separately or did it come installed on the computer?

Does the problem happen at home or in the work environment?

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":

Inspiron 7558

Bought new 6 yrs ago, home use, built in wireless 

spectrum old dual band router/modem setup required frequent resets. Last week installed new spectrum single band modem/router, it auto chooses 2.4/5.  All other devices can see the new network except the laptop. Spectrum said router is 3.1. 

no other hardware/software changes 

On the new spectrum router data tag is says Wi-Fi 6 router. Shows serial number, MAC address and HW Version:7.2

I haven’t been able to try the laptop on a different network. I’ll do that  and run the ssu report
