Network – Macs Wifi shuts down automatically after rebooting

My WiFi in Mac (with MacOS Mojave 10.14.6 (18G87)) can not be turned off even after several attempts

  1. Reset SMC
  2. PRAM reset
  3. Delete the airport.plist files
  4. Restart several times.

behavior

When I restart, the WLAN will work for some time. It stays on, connected and works as intended. I have internet, but after a while it just turns off and clicks Turn on Wi-Fi Infinite times are useless.

Any idea why this behavior happens?

This is what my system information shows. It changes from en3 to en0

Network – Poor Wi-Fi performance on the iPhone

When migrating to a new router, I found that my iPhone (7Plus) had a lousy TX performance compared to the others 80211.ac Apple devices connected to the same Wi-Fi SSID as shown in the screenshot below:

BEFORE fig

Since this was a new router, I assumed there might be an inconsistent configuration somewhere. Everything checked; all good.

Comparative analysis: What sets this iPhone apart from other devices that work properly?!?!?

I noticed that my iPhone was right next to the router. So I set it up about a meter away (in the same room). Still terrible TX performance on just this one device. Aside from the proximity (which I've just reviewed), which can affect Wi-Fi performance, why was not this iPhone performing?!?!?

The offensive case (wood with a kind of rubberized material) is pictured below at the request of Dan:

Wi-Fi – Wi-Fi can not be enabled or / and its settings can not be changed

Some time ago without obvious cause it started. When I try to enable Wi-Fi via the icon or change the settings, the icon changes as if it were enabled. However, if I navigate to another location and back, it will be displayed as disabled again. And the Internet does not work over Wi-Fi. Also, I've tried to change the bandwidth frequency from automatic to 5 – if I go somewhere and back, the automatic mode is reactivated. Is it more of a software or hardware problem? What can I do to continue testing?

The device is Xiaomi with Android 6, when it matters.

Wireless network – No Wi-Fi after upgrading to Ubuntu 19.04

I upgraded to Ubuntu 19.04 two weeks ago. Two weeks ago I ran an update and the basic Ubuntu package update was not installed. A week ago, it was again trying to get the message that third-party updates (I own VirtualBox and Chrome) disabled and a command (I think it was sudo apt-get install -f & # 39;) in the terminal to be executed.
First, the display was shaky, then I lost Wi-Fi. & # 39; No network devices & # 39 ;. I googled like crazy and tried different things without success.
I have Wi-Fi on Windows 10 (dual boot) and also on the previous kernel version (5.0.0-21), so I can continue to use Ubuntu. However, for security reasons, it is advisable to rely on an earlier kernel version? If this is ok, I will continue to use the previous version instead of the current version (5.0.0-23).
Googling seems to be a problem with Realtek, Dual Boot and 19.04. From the file & # 39; wireless-info & # 39; It turns out that I have a RTL8188CE 802.11b / g / n wireless adapter (10ec: 8176) (Rev. 01).
Out of frustration, I tried to reinstall Ubuntu 19.04 from DVD, but that could not find my WLAN, so I canceled it.
I posted on askubuntu.com (https://askubuntu.com/questions/1163588/no-wifi-after-upgrade) and was told to run https://github.com/UbuntuForums/wireless-info. I have not received any feedback on the results found here: https://paste.ubuntu.com/p/kFTK62fmqB/
Can someone help? Thanks a lot!

Terminal – My MacBook Pro keeps disconnecting itself from a working Wi-Fi network. Genius can not figure it out. Any ideas?

The WiFi is ok. My MacBook is just disconnected. As soon as I click on the network again, a connection is established immediately. Only the connection to the network is disconnected.

This is a list of disconnects on my Wi-Fi network in the last 24 hours (I've tried to do this in image format, but the screenshot was apparently too big):
