The moment my wifi connection is re-enabled/selected, universal control drops out. If I leave wifi on and unselect my wifi connection, universal control works. Universal Control: Not working with iPad Mini with wifi enabled on MacBook Pro 14 Does anyone have any issues with trying to get the universal control to work with iPad mini 6 or any iPads? I have issues with my MacBook Pro 14 inch trying to link to my iPad when my wifi connection is selected. Your suggestions and speculations will be welcome. How does macOS learn of this problem? Does the modem somehow tell it? Where are logs stored where I can see timestamps for when this alert came up? To help me research this problem, I have two questions: I'd love to ask our ISP to try replacing our DSL modem, but, by the time I were to initiate a service call, the situation would have cleared. About 15 devices connect to the web (and sometimes each other) via a DSL modem/router and one extender. Again, their experiences seem to occur at unique times, while all other devices and computers on our LAN continue uninterrupted web access in the meantime. Other non-computer devices on our LAN (Roku, Echo, iPad, garden sprinkler timer) also seem to experience a web access outage in a similar pattern: for a few minutes a few times a week. The alert box stays up, however, so we'll know that it did happen. The affected computer can connect via WiFi to the web via another path, such as an iPhone, and that works OK.Īfter a few minutes, the situation clears: The affected computer's WiFi icon in the menu bar returns to normal and its web interface returns. The WiFi symbol in the screen-top menu bar of the affected computer displays a dimmed icon with a bang "!" over it. The affected computer is not connected to the web, but all other computers remain connected and seem to work fine. While one computer is experiencing this situation, At least three Macintosh computers on our LAN, each running a different operating system, get this message and experience this effect, then recover in a few minutes, a few times a week. This situation lasts a few minutes, then recovers by itself. The user clients and Screenbeam devices are in the same vlan.Another device on the network is using your computer's IP address. On the guest network, I set Broadcast filtering to Disabled, and Deny inter user bridging to off, but it still didn't work.Turned on AirGroup with Enable Bonjour, Guest Bonjour multicast, allowall, but it still didn't work.On the Aruba Instant AP network, I tried the following: I took it back home, and again it works great. I took it into the building expecting the same, as the Cisco LAN is the same, but with Aruba AP's, and it worked one time on the Internal network, and never on the guest network. I configured and tested it at home in a Cisco LAN environment with Meraki AP's, and it worked flawlessly. Is Screenbeam still working ok for you? We purchased a Screenbeam 1100 for our organization. Subject: Aruba upgrade causes Miracast projection failures Theories so far: DRC interference seen as rogue device switch configuration in this building. I know this because an engineer from Screenbeam responded to a thread I posted on another forum and gathered data for us to help troubleshoot his client's problem you can see our session in this video. It is also close to the hospital and state emergency communications towers (we are in the capitol city) there is a small airport and an Army national guard base about 2 miles away.Īnother district in another area of the country is having the same problem, and also has Aruba equipment. Problems are throughout the building, but seem to be concentrated on higher floors (whether that is related to the height, a physical aspect of the floors, the switches, or VC's, I don't know). Location: only occurring in one school building out of 8. Test laptops do work fine in other school buildings. We've updated drivers and operating systems. Laptops: we have multiple models of Dell 5310 & Lenovo windows 10 laptops showing the problem, all using Intel AX201 160Mhz NICs. Symptoms: as soon as we press Windows K to scan for devices to connect to, the laptop's network slows to a crawl (ping -t response times shoot up speedtests fall to under 1M). Miracast, as I understand it, using the wireless NIC and both 2.4 & 5GHz, but is a point-to-point connection. In every classroom in the district, we have miracast devices (Microsoft wireless display adapters) which allow our teachers to project wirelessly from their Windows 10 laptops to their projectors. We had 200-series APs in a controller environment and upgraded over the holidays this winter to 500-series APs using Aruba Central. We are a public school district which has been using Aruba since 2016. We have a TAC open, but it's been 3 weeks and I wanted to put this out here - any direction would be much appreciated!
