Boosting your Wi-Fi signal through walls can be done in a few different ways. The simplest and most cost-effective way is to use a Wi-Fi range extender. These devices will amplify your existing Wi-Fi signal and extend the range of your network, allowing you to get better coverage in areas of your home that previously had poor signal. Another way to boost your Wi-Fi signal is to upgrade your router antenna. A higher gain antenna will direct the Wi-Fi signal in a specific direction, allowing for better coverage and stronger signal strength. You can also try setting up a wireless mesh network. This involves setting up multiple access points in different areas of your home and connecting them together. This will create a larger coverage area and allow for better Wi-Fi signal strength. Finally, you can also try using Wi-Fi channel bonding. This technology will combine two or more Wi-Fi channels together to create one larger, faster channel. This will allow you to take advantage of the increased bandwidth and get better performance.
