Please try the following:
1 - Set the preferred band to Prefer 2.4GHz band
2 - Set the HT Mode to HT mode for 802.11n compatibility. VHT mode is for 802.11ac compatibility.
3 - Set the 802.11n Channel Width for 2.4 to limited 20MHz. Please understand that 20MHz has smaller dandwidth than 40MHz, but has better penetration capabilities which improves the connection signal.
Furthermore, as additional information, turning off Bluetooth* if there is no need to have it on, would increase your experience positively.The wireless and Bluetooth* combo card share the same bandwidth and the antennas, so by turning off the Bluetooth* function will allow the wireless connection to have the entire usage of bandwidth and the antennas if choosing 2.4GHz band as it also decreases the signal interference since Bluetooth* devices use the same band.
