![]() Ideally, you are looking to fall in the -60 dBm to -50 dBm range (since -30 dBm is unlikely). You are not likely to connect to internet at this level. You may be able to connect to your network, but you will not support most online activity. 80 dBm: This is an unreliable signal strength. 70 dBm: This is not a strong signal strength. This is the minimum for any online services that require a reliable connection and Wi-Fi signal strength. ![]() 67 dBm: This is a reliable signal strength. 50 dBm: This is considered an excellent signal strength. If you have this measurement, you are likely standing right next to the access point. 30 dBm: This is the maximum signal strength. Here is what the scale looks like and what each signal strength measurement means: Any signal between -67 to -30 dBm will let you perform most online activities. Likely, you do not have a perfect signal, but that is OK. What is a good signal?Ī perfect signal is -30 dBm. Signals measured in dBm will display as negative numbers. ![]() Understanding different measurements like milliwatts (mW) or Received Signal Strength Indicator (RSSI) can be helpful, but it is more common that you will see signals measured in dBm. Wi-Fi signal strength is measured in multiple ways, but the most common is in decibels per milliwatt (dBm). It doesn’t matter if you are using a phone, tablet or laptop, you will need a strong Wi-Fi signal for all of them to browse the web, check emails, stream videos and more. We wrote a whole article on how to run a test to check your Wi-Fi signal strength. ![]() You need a good Wi-Fi signal strength for different online activities. Wi-Fi signal strength refers to the reliability of your Wi-Fi network connection. This will generally give you better performance and let you isolate each Wifi interface separately to examine the differences in functionality and performance between the two radios.Have you ever had your Internet completely cut out? Sometimes, this is because of obstacles, but other times it is because you have a bad Wi-Fi signal strength. To further remove variation from testing, you can use one of these interfaces to connect to CDRouter’s simulated WAN or LAN ports. It may also require some specific configuration changes in your CDRouter config.Īlternatively, many range extenders also have wired Ethernet ports. To enable bridge mode within CDRouter, set the testvar forwardingMode to bridge. CDRouter will assign IP addresses to its simulated LAN hosts on the same network as the booster’s management interface to run management protocol tests. If the booster has a management IP interface, it will receive one via DHCP from CDRouter’s simulated server. In this setup, test traffic passes through the booster directly (acting as a bridge itself). You can perform testing on a Wifi range extender directly by using two of CDRouter’s Wifi interfaces to simulate both ends of the test loop (called “Wifi on the WAN”). It’s not necessary to use an in-line access point to test a Wifi range extender. Setting up a Wifi range extender test using two wlan interfaces CDRouter’s wlan test interface will force itself to connect to that specific node in the mesh. To do this, use the lanBSSID testvar, and set it to the BSSID of the Wifi node. When there are multiple repeaters forming a mesh, as is the case with a lot of consumer Wifi systems, it’s best to isolate the DUT that you want by telling CDRouter which BSSID in the mesh to connect to. A Wifi booster or Wifi range extender is sometimes a simple repeater, but more often they act as layer 2 bridges, and can still be tested for performance and management via TR-069 or SNMP. ![]() Devices that enhance consumer Wifi are becoming more and more prevalent, both off the shelf and deployed by service providers. ![]()
