To ensure that your devices can connect securely and reliably to your network, apply these settings consistently to each Wi-Fi router and access point, and to each band of a dual-band, tri-band, or other multiband router. Before changing the settings, you should take these steps:
The security setting defines the type of authentication and encryption used by your router, and the level of privacy protection for data transmitted over its network. Whichever setting you choose, always set a strong password for joining the network.
Don't create or join networks that use older, deprecated security protocols. These are no longer secure, they reduce network reliability and performance, and they cause your device to show a security warning:
Settings that turn off security, such as None, Open, or Unsecured, are also strongly discouraged. Turning off security disables authentication and encryption and allows anyone to join your network, access its shared resources (including printers, computers, and smart devices), use your internet connection, and monitor the websites you visit and other data transmitted over your network or internet connection. This is a risk even if security is turned off temporarily or for a guest network.
The Wi-Fi network name, or SSID (service set identifier), is the name your network uses to advertise its presence to other devices. It's also the name that nearby users see on their device's list of available networks.
If you don't follow this guidance, devices might not connect reliably to your network, to all routers on your network, or to all available bands of your routers. And devices that join your network are more likely to encounter other networks that have the same name, and then automatically try to connect to them.
Hiding the network name doesn't conceal the network from detection or secure it against unauthorized access. And because of the way that devices search for and connect to Wi-Fi networks, using a hidden network might expose information that can be used to identify you and the hidden networks you use, such as your home network. When connected to a hidden network, your device might show a privacy warning because of this privacy risk.
When this feature is enabled, your router can be set up to allow only devices that have specified MAC (media access control) addresses to join the network. You shouldn't rely on this feature to prevent unauthorized access to your network, for these reasons:
If possible, set your router to automatically install software and firmware updates as they become available. These updates can affect the security settings available to you, and they deliver other important improvements to the stability, performance, and security of your router.
It's usually best to enable every mode offered by your router, rather then a subset of those modes. All devices, including older devices, can then connect using the fastest radio mode they support. This also helps reduce interference from nearby legacy networks and devices.
Each band of your router is divided into multiple, independent communication channels, like lanes in a street. When channel selection is set to automatic, your router selects the best Wi-Fi channel for you.
If your router doesn't support automatic channel selection, choose whichever channel performs best in your network environment. That varies depending on the Wi-Fi interference in your network environment, which can include interference from any other routers and devices that are using the same channel. If you have multiple routers, configure each to use a different channel, especially if they are close to each other.
DHCP (dynamic host configuration protocol) assigns IP addresses to devices on your network. Each IP address identifies a device on the network and enables it to communicate with other devices on the network and internet. A network device needs an IP address much like a phone needs a phone number.
Your network should have only one DHCP server. If DHCP is enabled on more than one device, such as on both your cable modem and router, address conflicts might prevent some devices from connecting to the internet or using network resources.
NAT (network address translation) translates between addresses on the internet and addresses on your network. NAT can be understood by imagining a company's mail department, where deliveries to employees at the company's street address are routed to employee offices within the building.
Make sure that your device has Location Services turned on for Wi-Fi networking, because regulations in each country or region define the Wi-Fi channels and wireless signal strength allowed there. Location Services helps to ensure that your device can reliably see and connect to nearby devices, and that it performs well when using Wi-Fi or features that rely on Wi-Fi, such as AirPlay or AirDrop.
Wireless carrier Wi-Fi networks are public networks set up by your wireless carrier and their partners. Your iPhone or other Apple cellular device treats them as known networks and automatically connects to them.
The upside of Wi-Fi? You can connect to the internet wirelessly. The downside? Others nearby who connect to your unprotected network might be able to see what you do online, including your personal information. And if anyone uses your network to commit a crime or send illegal spam, the activity could be traced back to you.
Protect your devices. Just as hackers can get to your data through unsecured networks, they can also get to your network through unsecured devices. To find tips on locking down your devices, read about keeping your devices secure.
Google Nest Wifi and Google Wifi secure your Wi-Fi network with either WPA2 protocol or the newer WPA3 protocol. Using WPA3 protocol makes your Wi-Fi network highly resistant to security risks like offline dictionary attacks.
By default, Google Nest Wifi and Google Wifi use the WPA2 protocol to maximize compatibility with legacy connected devices (such as phones, tablets, or laptops). However, you can turn on WPA3 transition mode in the Google Home app. This setting allows both WPA2 and WPA3 devices to join your Wi-Fi network. For Google Wifi devices initially set up in the Google Wifi app, you will need to add your network to the Google Home app to use this feature.
A network access control list (ACL) is made up of rules that either allow access to a computer environment or deny it. In a way, an ACL is like a guest list at an exclusive club. Only those on the list are allowed in the doors. This enables administrators to ensure that, unless the proper credentials are presented by the device, it cannot gain access.
When ACLs were first conceived, they worked like firewalls, blocking access to unwanted entities. While many firewalls have network access control functions, some organizations still use ACLs with technologies such as virtual private networks (VPNs). In this way, an administrator can dictate which kinds of traffic get encrypted and then sent through the secure tunnel of the VPN.
Networking ACLs are different in that they are installed in switches and routers. Here, they are traffic filters. To filter traffic, a network ACL uses rules that have been predefined by an administrator or the manufacturer. These rules check the contents of packets against tables that govern access parameters. Based on whether the user checks out, their access is either granted or denied.
Also, with FortiNAC, you can protect not just wired networks but wireless ones as well. This is accomplished using a centralized architecture that allows you to deploy access control solutions across your entire network, as well as automate how the system reacts to requests.
An access control list on a router consists of a table that stipulates which kinds of traffic are allowed to access the system. The router is placed between the incoming traffic and the rest of the network or a specific segment of the network, such as the demilitarized zone (DMZ). The ACL examines the information held within data packets flowing into or out of the network to determine where it came from and where it is going. The ACL on the router then decides whether the data packet should be allowed to pass to the other side.
Your home network is naturally vulnerable, which means the responsibility falls on you, the end user, to keep an eye out for signs of suspicious activity and figure out what to do if your network is hacked.
Once a hacker has access to your computer, they also have access to all of your data, including sensitive documents, emails and images. They can also install new software on your computer and uninstall security measures like your antivirus and firewall.
If your default browser changes suddenly or redirects you to an unfamiliar page, then your home network has probably been hacked. Usually, this type of activity is caused by a browser redirect virus. Be especially careful with browser redirects, since attackers may send you to a spoof website where they will try to harvest personal or financial information.
When the VPNFilter malware gained infamy in 2018, the FBI recommended a router reboot as the best way to get rid of the virus. Every wireless router comes with a reset button that restores the router to its default settings. When you hit the reset button, it will disrupt anyone lurking in your network.
Remote administration is a setting on your router that permits someone to access your system from a far-away location. While the setting can be useful in some legitimate scenarios, it can also be abused by hackers. There are red flags that a hacker has gained remote access to your computer, such as when your cursor moves on its own or programs seem to install themselves all on their own. Deactivating remote administration will no longer allow hackers to abuse that feature to access your network.
There are multiple ways to hack a home network, and one of them is via malware. Certain viruses, like a keylogger, record everything you type on your keyboard, including your usernames and passwords. Running a virus scan should detect and remove any malicious software lingering around on your computer. 2b1af7f3a8
