First of all, the first piece of advice we give you before you even get your hands on the settings of your PCs and smart devices, is trivially to perform a connection test, so that you can see what problems you are experiencing in both download and, possibly, upload. For this, we recommend Ookla’s Speedtest, which can be used free of charge at this address.
One of the first solutions you can possibly adopt in the event of a slow connection is to change the DNS servers, i.e. those servers responsible for translating the nodes of the network into IP addresses. If you have Windows as your operating system, simply go to ‘Network and Internet’ and change the value of the DNS parameter, filling it in with the following value, “8.8.8.8/8.8.4.4″, which corresponds to Google’s DNS.
If you have a MacBook with the MacOS operating system, on the other hand, you will need to go to Preferences, click on Network, continue on Advanced, and change the DNS parameter, both primary and secondary, again with the value 8.8.8.8/8.8.4.4 mentioned above. Changing the Wi-Fi channel can also be a good solution to avoid interference that would significantly slow down your Internet connection. In this case, you will need to turn to the settings of your router (reachable by entering the address 192.168.1.1 in the search bar of your browser).
If you use your wireless device far away from your home router (perhaps on a different floor from where the router itself is located), it is useful to make use of a wireless repeater, which connects to the router and extends the Wi-Fi connection, avoiding the risk of slowing it down due to distance. Even between browsers, surfing speed changes. If you are using Internet Explorer, for example, our advice is to try switching to Google Chrome, which allows you to open web pages faster.
