The wireless network card of the old laptop may not support wpa2 encryption.

When an old laptop is connected to a NETGEAR wireless router with wpa2 encryption, it will always be in the "getting network addresses" status. Disable the wireless feature of the notebook and re-open it. The problem persists, as a result, the laptop may be old, and its wireless network card does not support wpa2 encryption, so the wireless route is changed to WPA to be slightly safer (not to be fooled by boring people ), A super abnormal long password (uppercase/lowercase letters + numbers) is set, and the notebook is connected again. Everything is normal.

If you do not want your wireless network to be seen by others, you can disable the SSID broadcast of the wireless router after you have configured all the wireless networks and can use them normally.
