In fact, anything worse than -70 dBm is not a strong signal. Wireless signal strength is measured in dBm and expressed as negative values, which means that, for example, -70 dBm is worse than -50 dBm. Signal strength: The strength of a WiFi connection is one of the most important measures because it directly affects your coverage and internet speeds.Here’s a brief overview of the information provided by the best WiFi analyzers for iOS: You can simply collect every detail about surrounding WiFi networks from one place and study their security, signal strength, noise, and configuration.īy combining these two methods, you can effortlessly select the optimal place for a WiFi router, set up a large enterprise WiFi network, or eliminate dead spots that are preventing you from fully enjoying your internet connection. ![]() ![]() If all you want to do is learn more information about other WiFi networks in your general area, you don’t have to go anywhere. This is easily done with WiFi analyzer iPad or iPhone apps because you can just walk from one place to the next and instantly see where your WiFi network leaves something to be desired. When analyzing your own WiFi network, you probably want to know where its coverage ends and uncover all areas of signal weakness, also known as dead spots. The comprehensive solution to this messy system:ġ) Make full backups (preferably at least two, on separate drives)Ģ) Make a Ventura installer on a thumb driveģ) (*) Boot from this installer drive, and:ģa) Use Disk Utility to reformat the whole internal drive as APFS (this will effectively erase it completely!)ģc) When asked, migrate ONLY the user accounts from the Time Machine backupo you made in step 1Ĥ) Install only the applications you do need, and NEVER EVER again install such crapware as "cleanmymac".You can use a WiFi analyzer in two different ways: to analyze your own WiFi network or to analyze other WiFi networks. You don't need old stuff made for intel macs running El Capitan, that you don't remember what was used for, polluting your new M1 Mac running Ventura. It is usually recommended to start fresh with each new OS - and particularly when moving to a new mac with a new architecture. It is hard to know which may or may not work in the present system. Getting rid of these conflicting stuff may help, but there are other issues probably due to those many old things lying around. Start by completely removing CleanMyMac, One Periodic, Sophos.Įffective defenses against malware and other threats You have more than one.Īntivirus software: CleanMyMac, One Periodic, Sophos, and Apple The correct number of third party antivirus is zero. More than one antivirus app - This computer has multiple antivirus apps installed. These issues do not need immediate attention but they may indicate future problems or opportunities for improvement. ![]() This could be a sign of hardware failure. Kernel panics - This system has experienced kernel panics. Unsigned files - There are unsigned software files installed that could be malicious and should be reviewed. No wonder there are problems.Īnything that appears on this list needs immediate attention. You have dozens of kernel extensions and daemons, some as old as OS X Lion (10.7). you have a lot of stuff that has been accumulated over the years, from one mac to another. This is easily one of the most polluted systems that I have seen around here.
