Antenna for Ralink Technology 802.11n wireless lan card

[kmbannar]

I am missing the antenna(s) for the wireless card.  As a result the wireless connection is very weak and not all available networks are showing.  The card is working properly and the driver is up to date.  I just need to replace the antenna(s).  Are the antennas one size fits all?  The hardware IDs are

@kmbannar Welcome to HP Community!

The antenna is inbuilt, its not something you can purchase an connect to your device, I suggest you use the below steps to improve the wifi signal performance, instead:

Go to Device manager > select the WIFI drivers under network adapter> Right click go to properties  > Under properties go to Power Management Tab> Uncheck  "Allow the computer to turn off this device to save power". 

If the issue persists, continue with the below steps: 

• If your computer has a wireless key or button on or near the keyboard and the wireless activity light is off or amber in color, then press the key or button to enable your wireless adapter. This key might be the F10 key, F12 key or labeled with a symbol of an airplane. 

• If wireless activity comes on or the activity light turns blue, you have enabled wireless on your system. Try connecting to the Internet again. If problems persist, continue using these steps. 

• If your computer does not have a wireless key or the wireless activity lights remains off or orange then continues using these steps. 

• Click Start, type troubleshooting into the Search field. 

• Select troubleshooting from the search results. 

• Click Network and Internet. 

• Click Internet Connections

Hello.  I previously tried the steps you listed.  No luck.  I googled the Ralink wireless card and it showed an external antenna.  There is bolt (for lack of a better word) on the back of the tower where it would screw on.  I have a wireless signal, it's just weak. Thank you for your time.

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
