And they mainly include deleting the Office app icons, removing related files, and unlocking apps from the Dock. In fact, the steps to remove Office 365, 2019, and 2016 are similar. Uninstalling newer versions of Office, such as Office 365, is more complicated than uninstalling Office 2011 because you have to delete not only the application itself but also related files stored on the hard drive. How to Uninstall Office 365, 2019, and 2016 on Mac Locate the Microsoft Office 2011 folder and move it to Trash. Open Finder in the Dock and go to the Applications folder.Quit all the Office applications first.To uninstall it, follow the following steps: Although you can continue to use its functions, you cannot keep up to date with all the latest features, patches, and security updates. Microsoft Office stopped supporting Office for Mac 2011 on October 10, 2017. This applies to the neighbor's Wi-Fi, which of course has the most impact when there are many smaller residences grouped closely together.īut additional Wi-Fi networks within the same household can also be a source of noise - for example if you have Wi-Fi running on a multi-function gateway in addition to a Wi-Fi mesh network.Īrticle by Geir Arne Rimala and Jorunn D.Make sure you have signed in to your administrator account on Mac. High Network Density Creates InterferenceĪny wireless network nearby can cause noise or interference to a Wi-Fi network. However, when many people are moved to the same channel at the same time, there is a high risk of congestion. The channel area marked in green is never used by radar, and that's where all connected clients are moved when a radar is detected. The channels marked in yellow on the illustration require radar scanning for 1 minute, and these are the channels we refer to when we are talking about dynamic frequency selection. This is so impractical that many Wi-Fi manufacturers choose not to to use these channels at all, because the network would otherwise be unavailable for 10 minutes at a time. Two of them - those marked in red on the illustration - require a radar scan for 10 minutes before you are allowed to connect to them. The illustration shows 80 MHz channels, which is what mesh Wi-Fi uses. When the device detects a radar, other connections are automatically moved onto different channels on the 5 GHz frequency band so as not to interfere with the radar.įive (non-overlapping) channels on the frequency band illustrated above are reserved for radars. This is solved in most routers and other wireless access points by a functionality called DFS – dynamic frequency selection. Simply put: The channels used for radar can also be used by Wi-Fi, as long as Wi-Fi moves as soon as a radar is nearby. This means that wireless networks can create interference for the radar, which is why anyone who produces Wi-Fi equipment is required by law to make sure their equipment does not get in the way of radars. This technology uses some of the same frequencies as wireless internet. Radar technology is used, among other things, in marine navigation to detect obstacles, avoid collisions, and so on. Radar and Dynamic Frequency Selection (DFS) In some cases it is even legally required for them to change channels. You can set up which channel a wireless network should use, but in most cases it is better to leave this decision to the Wi-Fi equipment itself. When (too) many clients are connected on the same channel, this can create Wi-Fi congestion - overload - and very poor performance on the networks. When there are multiple Wi-Fi networks in close proximity to each other, the ideal is for these networks to make use of wireless channels that do not overlap. Wireless internet (Wi-Fi) uses two frequency bands:Įach frequency band is divided into smaller areas called channels.
