When I connect my laptop to Wi-Fi using the default MAC address, it connects but shows "no internet connection." The internet connection only works when I use a random MAC address. I've reset the router twice, but this problem keeps recurring every 2-3 days. The issue occurs with the default MAC address on the 5GHz frequency, and the 2.4GHz frequency doesn't connect at all with the laptop's default MAC address. The router is using channel 1 (40MHz) for 2.4GHz and channel 128 (160MHz) for 5GHz, and the laptop's Wi-Fi card is an Intel AX201 160MHz.
