Hi Kitsap,

 

Thank you for your fast response.

My modem is: ARRIS - SURFboard SB6190 32 x 8 DOCSIS 3.0 Cable Modem,

The Router Firmware version is V1.3.3.154_10.1.86.

I don't know the neighbors broadcasting Wi-Fi on the 5 GHz band.

Good things.   Your modem is a modem only and not a combination modem/router.  Your router firmware is current.

Log in to the user interface and check your 5 GHz Wi-Fi settings for channel, mode, and security.  Usually under the Advanced -> Setup -> Wireless Setup tab.  DFS channels can occasionally be knocked off line.  See attached screen snip.  I recommend Smart Connect be disabled so you have different SSIDs for the different bands.

Your radio frequency environment (neighbors) can have an impact on your connection.  There are a couple of scanning applications for mobile devices that can give you a picture of your situation.  I use an Android device.  There is a section in the Netgear mobile application called Wi-Fi Analytics and there is an application called WiFiman from Ubiquiti.  They should be available in the Play Store of your mobile device.  Look to see if the 5 GHz channel you are using is broadcasting the same as your neighbors or on a DFS channel.

Wi-Fi has a lot of variables that impact your connection and your satisfaction with performance.  Some background reading to help your understanding can be found here:  https://www.duckware.com/tech/wifi-in-the-us.html.  Duckware is a good reference.  Do not try to swallow the whole thing at one time.  Review of the first few chapters is a good start.
