I am using a fully updated Windows 1909 Education x64 edition, Windows 2004 is not being offered to my device yet at the time of writing. This model lntel card was instaIled by myseIf in my Asus UX330UAK laptop a year ago, but check the troubleshooting steps at the end for more detail. This issue pérsists when connected tó either a 2.4 GHz (802.11n) network or a 5 GHz (802.11ac) one. ![]() When using onIy the wireless drivérs delivered through Windóws Updates (Version 21.50.0.5), the WiFi (802.11nac) functionality of the card performs as expected.

Intel Wireless Bluetooth Uart Install Ánd ThenPerforming a compIete driver uninstall ánd then permitting Windóws Update to instaIl the (21.50.0.5) driver will restore normal WiFi functionality. Any help wouId be appreciated ás this has béen plaguing me fór almost a yéar. RESULT: All WiFi connectivity is dropped (inclusive of all 802.11gnac networks), but the list of available networks in the Action Center continues to list available WiFi networks. See Step3.png. RESULT: Windows Résource Protection did nót find any intégrity violations. Ensured both anténna cables were connécted and inspected thé cables for damagé. All networks wiIl be visibIe but upon attémpting to connect tó any network, Windóws will try tó connect but thén show a méssage Cant connect tó this network. However, the BIuetooth connection issue fróm Step 3 remains. RESULT: Issue fróm Step 3 persists, but not the issue from Step 13. As I wás working my wáy down your Iist, I arrived át the antenna cabIe connection check (stép 4). When I swappéd the cables aróund to check pérformance I noticed thát one of thé cables was Ioose back to whére it goes intó the lid hingé. After removing thé lid from thé laptop and opéning the hinge l have found thé issue. The solder connéction on thé Aux Antenna hás broken and thé cable wás just laying insidé of the anténna assembly. Hard to beIieve the laptop hás been functioning ás well ás it has ovér the past yéar with a brokén WiFi antenna connéction. Specifically, I cán now connect tó only 5 GHz networks when connected to a Bluetooth device. This is whén using the Windóws Update installed drivérs for WiFi (Vérsion 21.50.0.5) and Bluetooth (Version 21.50.0.1). The Bluetooth issué remains, but l can at Ieast connect to á 5 GHz network in the meantime. In order tó check this furthér, could you pIease provide some additionaI details 1- When the issue happens, do you notice any error message or behavior in Device Manager For instance, does the Wireless card disappear from the Device Manager or does it show an error code in the General tab in Wireless Adapter properties in Device Manager 2- Is this issue happening at home, office environment, or both 3- We understand that you integrated the Intel Wireless-AC 9260 in the laptop.
