I am using Dell laptop and it has old wifi driver. So I am using Tp-link AC1300 T3U for my wifi connection. When I connect to wifi, it shows connected in settings but actually there is no internet access and a Question mark is showing on wifi mark.

I have changed DNS and the problem remain same. If I connect the same wifi with my laptop's wifi then it got connected and also have internet access.

Please help me to solve this problem, else I have to shift to windows which I don't want. I provide all detail which you want. for now I am at Ubuntu 22.04 LTS.

Result of following command is: lspci -nnk | grep 0280 -A3 for above command

    Subsystem: Dell QCA9377 802.11ac Wireless Network Adapter [1028:1810]
    Kernel driver in use: ath10k_pci
    Kernel modules: ath10k_pci

and for rfkill list all the result is:

2: phy1: Wireless LAN
    Soft blocked: no
    Hard blocked: no
