The HP 250 G3 Notebook PC may want to replace the Ralink RT3290 802.11bgn Wi‑Fi/Bluetooth module due to Bluetooth issues, wireless connectivity limitations, or to upgrade to a dual-band wireless adapter.
The HP 250 G3 Notebook PC may be equipped with a Ralink RT3290 wireless card. Users seeking improved wireless performance or Bluetooth functionality can replace the module with a compatible wireless adapter. However, successful upgrades depend on the processor type and the notebook's antenna configuration. Systems with only one antenna may experience limited Bluetooth or 5 GHz Wi‑Fi functionality after the upgrade.
Troubleshooting Steps

Open Device Manager.
Expand Network Adapters.
Confirm the installed adapter is Ralink RT3290 802.11bgn.
2. Check Processor Compatibility
Before replacing the WLAN module:
If the notebook has an Intel Core processor, a compatible upgrade option is the Intel Dual Band Wireless-AC 7260.
If the notebook has a Pentium or Celeron processor, a compatible alternative is the Broadcom BCM4352.
3. Verify Antenna Configuration
Power off the notebook.
Access the WLAN card compartment.
Check whether the notebook has:
One antenna cable (Main), or
Two antenna cables (Main and Aux).
Note: The second antenna is used to improve Wi‑Fi reception and support full wireless functionality.
4. Replace the Wireless Module
Shut down the computer.
Disconnect AC power.
Remove the battery (if removable).
Remove the existing Ralink RT3290 card.
Install the replacement wireless card.
Connect the available antenna cable(s).
Reassemble the notebook.
