What, precisely, does "reset network settings" do on an iPhone? resetting network settings will remove all saved WiFi passwords in iCloud keychain, effectively deleting remembered WiFi networks from all your signed in devices. A workaround: turn off iCloud Keychain, then reset network settings, then turn iCloud Keychain back on. Your saved WiFi ...

No, reseting the Network settings only deletes all the network settings on that particular device. Your different apple devices have your same Apple ID and your iCloud Keychain is synced on all those devices. So keychain syncs the passwords between all those devices.

I've had this problem on PCs too. Turned out to be my router. I replaced it with a Ubiquiti Unifi LR Access Point and that fixed all of my issues. The Unifi is a little harder to setup because it has a software controller but the speeds are insane. I get 50-75 Mbps downloads frequently. The TX rate in the picture you posted is literally 108.37 MB/Sec so ...

WiFi devices will reduce speeds if they detect too many errors at the higher rates. For example, in your screenshot, your WiFi radio has negotiated a fairly decent RF speed (MCS 9, 867Mbps) with the router. (It would be interesting to see what the router says, as Tx and Rx can differ.) Over time, radio link quality changes, causing the radios at both ends ...

As @andrew-morozko suggested, Raspberry does not not redirect incoming packets to the vpn connection without configuration: sudo iptables -t nat -I POSTROUTING 1 -o tun0 -j MASQUERADE sudo iptables -I FORWARD 1 -i tun0 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT sudo iptables -I FORWARD 1 -i eth0 -o tun0 -j ACCEPT

I bumped into this question when searching for the problem. And I figured out iCloud didn't set up (or logged in) on my Mac OS X. When I logged in to icloud, KeyChain access created a new tab for iCloud just under the Login tab. Please be sure, you set up iCloud on your Mac OS X. https://support.apple.com/en-us/HT208682

Removing the custom DNS servers entry from Network preferences resolved the issue for me.

Unfortunately macOS does not provide a way to blacklist a specific access point. On some other operating system you can do this via the BSSID (basic service set identifier) of the access point. You were referring to a MAC, but it is not really a MAC - but rather a BSSID. The BSSID is usually derived from the actual MAC of the access point though, but it is ...

Have you confirmed if the hotel's wifi connection requires logging in via a connection splash page in the browser? (I would post this as a comment, but I can't)

I turned out that because I paired it with my phone, it was not in the pairing mode anymore. So, I held the power button for 10 seconds or so and it went into the pairing mode again and I was able to see it in my bluetooth menu.

There’s not much you can do but restart and remove any 2.4 ghz interference sources. iOS has some tips like making sure the device is reset. If it’s paired with your android, it might not broadcast it’s looking to pair with your Mac. https://support.apple.com/en-us/HT201205

I think this is a normal situation as well - see my answers here: Why is my Wi-Fi process using 3GB of memory? Why is my Wi-Fi Process eating >2GB memory I don't think there is any leak or issue on Apple side - just some programs you run open lots of connections and if they have bugs or you have more tabs open one day versos another and the specific web ...

This is expected if you have a lot of networking. I'll close this as a duplicate of a couple questions covering this, but if you @ me in comments if you edit this to cover new ground we can revisit the hold / close.

TL;DR - Your Wi-Fi program uses memory when you have network connections. It starts with little allocation and when you run other programs, Wi-Fi uses memory to do that work. Log out to free that memory if you don't want to quit programs or thr don’t release their connections to your liking. Why is my Wi-Fi process using 3GB of memory? As a developer (or ...

First thing first - memory is virtual, so Wi-Fi could take 100 GB and you might only have a low grade leak that seems bad, but in practice has no effect whatsoever over a two week period or longer. Here how I’d evaluate this measurement in context : What is the overall memory pressure graph like on the machine? How long after you started did it take to get ...

I have a late 2012 Macbook pro and changing the Wireless channel width from auto and/or 80MHz to 40MHz solved my problem. I was literally about to bang my head against the wall by the time I came across this solution.

This is Cisco's public document on the topic. https://www.cisco.com/c/en/us/support/docs/wireless/aironet-3800-series-access-points/214491-arp-responses-for-default-gateway-ip-add.html The issue is real. I have 1st hand experience with it at large scale. I have seen actual packet captures of the behavior described in the article. The workarounds listed ...
