RTL8822CE 802.11AC PCle adapter running slow on 5Ghz wireless

[VenkatHS]

 My laptop Wi-fi adaptor is   Realtek RTL8822CE 802.11ac PCIe Adapter . When connected to the modem / router via 5Ghz band, it runs only at 25 Mbps contrary to the router wireless speed of 400Mbps !  Need help to fix this slow speed operation.

Some notes :

The Wi-Fi status via the network & sharing centre shows a speed of 54Mbps with a signal strength of 5 bars.  (2.4 Ghz band is running at 90 Mbps though ) .  ( Not on 802.11 ac? )

Tried disabling and enabling the device.  Didnt make any difference.

Channel width selection setting is "Auto "  (Btw, it shows "802.11n channel width 5.2Ghz" )

Driver installed is the latest version  2024.10.228.3  

 Laptop model is Pavilion 15-eh1101AU  (4X7E6PA)

Any help would be deeply appreciated to get my 5Ghz connection running at top speed..

Thanks
