Method 3: Renew IP and DNS addresses
DNS serves to translate server names into IP addresses and vice versa. All this data is stored in the DNS cache, and when it fills up, it can lead to connection loss. To address this, follow these steps:
Step 1: In the search bar, type cmd and from the search results, right-click on Command prompt, then select Run as administrator.
Step 2: Enter the following command lines one by one and press Enter after each:
ipconfig /release
ipconfig /renew
Step 3: Wait for a moment and continue typing the following command line, then press Enter:
ipconfig /flushdns
Step 4: Finally, simply close the Command Prompt window and try reconnecting to the Wifi to see if the issue of the laptop not connecting to Wifi has been resolved.
Method 4: Set the frequency to 2.4 GHz instead of 5 GHz for dual-band Wifi
Although the 5 GHz frequency runs faster and more stably, the 2.4 GHz frequency broadcasts signals over a longer distance, can penetrate walls, and is compatible with many older wireless devices. Therefore, if other devices in your home are using the 5 GHz frequency and can connect smoothly to Wifi, consider switching back to 2.4 GHz like your laptop.
Step 1: First, press Windows + S, and type Control to open the Control Panel.
Step 2: Set the View by option to Category, then find and click on Network and Internet.
Step 3: Select Network and Sharing Center. On the left panel, choose Change adapter settings.
