Can’t Detect WiFi Network on a Dell Laptop

[PHAM8899]

NEED SUPPORT FOR DETECTION WI-FI NETWORK. 

I can scan for many available Wi-Fi connections nearby, but not that at my house. Vice versa, my network appears on all other devices and works properly. 
Some details about my laptop: Dell Vostro purchased in 2015, but it has dualband wifi that works for both 2,4 and 5g.

As suggested by Roger customer service personnel, I went  to Roger center to ensure that my laptop can connect to other Roger networks. After successfully connecting to the network at the store, Roger staff at store advised me to call customer service and have someone come to my house to check on the network.
I spoke with many technical support staff from Roger and Dell to check on the network and the laptop itself in order to find a solution. Dell personnel confirmed that the hardware is operational. Rogers tech support advised me to reset and reconfigure the network modem, but this did not resolve the issue. He told me it was an isolated problem that only occurred in my laptop, which appears to be a third-party issue, so he sent me here to look for a solution myself.
Has anyone else had this happen to them? Please let me know.

Hello, @PHAM8899.

Thank you for posting your concern, and welcome to our Community! 😃

One of the devices not detecting the home WiFi network typically points to incompatibility of the WiFi adapter. I appreciate you trying resetting/reconfiguring the modem. 

For testing purposes, you can try disabling the band steering and try connecting your laptop to the 2.4 GHz network:

• Open the Ignite WiFi Hub app
• Tap on "Connect" at the bottom
• Tap on your home network
• Tap on the Pencil next to My Network
• Check the box > Use different names and passwords for 2.4 GHz...
• Under 5 GHz WiFi, Change the WiFi name. You can just add a number to change the name
• Tap on Apply Changes at the bottom

Turn WiFi Off/On on your laptop. Hopefully, you will see your home network, and you can connect. 

Irrespective of whether your laptop connects or not; we need to reverse the above changes so the rest of the devices can connect to WiFi. Revert the 5 GHz WiFi name, uncheck the box > Use different names and passwords for 2.4 GHz..., and Apply Changes. 

The other option would be to look into Wireless USB Adapters for your laptop. 

Cheers,
