HP Pavilion Desktop - 550-153w

My PC's wireless network card cannot handle my new T-Mobile 5G Gateway.  I soon learned that it always crashes my PC because the wireless network card isn't designed for the 5v GHz signal.  I bought a USB adapter that supposedly fixes this but it doesn't work.  When I disable the internal card it doesn't help.  Troubleshooting is pointless; all it tells me is that it can't detect a network, even though it shows up every time I go online.  The new network also shows up in the list of known (Control Panel/Networks & Internet/Wi-Fi/ Manage known networks).

Hi @OJ75,

 

Welcome to the HP Support Community. 

 

I'd like to help!

 

If you have checked the authentication type on the wireless NIC and are sure you have entered the password/passphrase correctly then you might start by flushing the wireless network information that the computer’s wireless network card has saved previously. It might be with the authentication type that the wireless NIC is using. Sometimes starting from default helps. If you are working with a Windows PC or an Apple or whatnot it still sometimes comes down to clearing out old information and starting over. 

Be sure to confirm if it is WPA, WPA2, or WPA3, and make sure the SSID on the gateway also includes the type that the client is trying to use. If the client only uses WPA and the gateway does not have WPA authentication then you might have to make config changes to allow it or if the client supports WPA2 authentication just set the client for WPA2. Some older clients can’t handle the newer authentication types. 

 

Also, try updating the BIOS. Click here

 

Hope this helps! Keep me posted for further assistance.

Thanks for your message.  Frankly it's too technical for me but I hope I can work it out.

 

For one thing, I have a desktop PC, a Pavilion 550-153W running 64-bit Windows 10.  The built-in network adapter is a Realtek RTL8723BE 802.11 bgn.  Needless to say it wont accept the 5 GHz signal from my T-Mobile 5G Gateway, so I bought and plugged in a TP-Link Archer T3U Nano, a.k.a. "AC1300 Nano Wireless Mu-MIMO USB adapter" and disabled the built-in card.  I can connect through the Nano with an existing "My-Fi" 4G device but the mere presence of the 5G, even before I log in, causes the Blue Screen of Death and it says there's a DPC WATCHDOG VIOLATION. 

 

As for flushing out info from the internal card, I don't have any idea how to do that.  Also, I don't know how to check those other thinks, like WPA and SSID.  I've been in contact with TP-Link for a month but they've yet to be of any help.

 

I will try updating the BIOS and anything else that might help.  But maybe there's nothing; in a month of searching the Internet I've yet to find an example of a computer like mine that has successfully worked with 5G.
