iOS 14.0.1 wifi issues

Go to settings and in the first group, if you see VPN, uninstall it. That worked for me. I also have a 7 that had no issues because there was no VPN. The VPN tried to connect. Once I deleted the vpn the connection was stable.

Go to Settings/Wi-Fi and tap on the i next to the network name.

• Is Auto-Join turned on? Does your network have SSID enabled?
• Is the network name unique, or is it a default name that might be used on other networks?
• Have you tried forgetting the network, then reconnecting?
• Have you tried Settings/General/Reset - Reset Network settings?

Try this team i found this on another forum... worked and is easy.

Forget the Wi-Fi Network, Toggle AirPlane Mode, then Rejoin

1. Open the Settings app, then go to “Wi-Fi”
2. Find the wi-fi network you’re connected to, then tap the “I” button next to the network name
3. Tap on “Forget This Network”
4. Exit out of Settings
5. Turn on AirPlane Mode by pulling down Control Center and tapping the AirPlane icon (or by activating it from Settings), leave it on for a few seconds, then turn AirPlane mode back off again
6. Return to the Settings app and go back to “Wi-Fi”
7. Re-join the wireless network you were previously connected to

Following-up on my previous post -

The post on the Apple Developer Forum has been updated with some great feedback, in particular, confirming my suspicion related to WiFi security type - see below:

Apple just told me that WPA-2 security is a known issue for ios 14. Their support rep said I should use WPA-3. Problem is my broadcom-based router (Netgear AC1750 purchased in 2018) does not offer WPA-3.

Chat transcript:

Apple:

Security

WPA3 Personal for better security, or WPA2/WPA3 Transitional for compatibility with older devices

The security setting defines the type of authentication and encryption used by your router, and the level of privacy protection for data transmitted over its network. Whichever level of security you choose, always set a strong password for joining the network.

• WPA3

Personal is the newest, most secure protocol currently available for Wi-Fi devices. It works with all devices that support Wi-Fi 6

(802.11ax), and some older devices. 

• WPA2/WPA3 Transitional is a mixed mode that uses WPA3 Personal with devices that support that protocol, while allowing older devices to use WPA2 Personal (AES) instead.

• WPA2 Personal (AES) is appropriate when you can't use one of the more secure modes. In that case, also choose AES as the

encryption or cipher type, if available.

Don't create or join networks that use older, deprecated security protocols like WPA/WPA2

Mixed Mode, WPA Personal, TKIP, Dynamic WEP (WEP with 802.1X), WEP Transitional Security Network, WEP Open, or WEP Shared. These are no longer secure, and they reduce network reliability and performance. Apple devices show a security warning when joining such networks.

Apologies, discard that  

Me:

OK

Apple:

Once you change the Security, you will need to monitor the devices for dropping connections intermittently 

Me:

So are you saying there is a problem with iOS using WPA2-PSK [AES]?

Apple:

Yes 

Me:

Introduced in iOS 12.4?

Apple:

Correct 

Is there anything else I can assist with today?

Unfortunately, this may mean that I have to invest in new network hardware, which is not ideal. Others having this connectivity issue should check their router settings per Apple's recommendation above to see if their settings can be modified and tested.

Does the problem happen with all Wi-Fi networks, or only your home network? If it is only your home network the problem is pretty obviously with your router, as it is affecting unrelated devices.

Also, have you updated to iOS 14.2, which fixes a known Wi-Fi problem with 14.0.1?

@steve.mccormick2

Thanks for sharing that information. For reference, I only have WPA2-PSK [AES] or WPA-PSK [TKIP] + WPA2-PSK [AES] as choices on my router and I had to change the setting to WPA-PSK [TKIP] + WPA2-PSK [AES] in order to make my WiFi stable on my phone again. You may want to tinker as a test - iOS will warn you that it is an insecure connection type but in my case I don't have another choice unless I upgrade my hardware. FWIW, my brother-in-law is using an earlier model of router than mine (Netgear Orbi) that only uses WPA and he never experienced the type of WiFi issues we have been seeing.

Re-posting my text from an earlier post for reference - this is another user's interaction with Apple where Apple confirms WPA2 is a known issue.:

I have an Iphone XR and unluckily upgraded to ios 14, now is ios 14.2. My wifi issues in home network started afterwards this upgrade., my home router does not support advanced encryption methods, only wpa, wpa-tkip and wpa aes are supported, I am aware that apple has a bug in ios 14 and upper versions to support these encryption methods.

I tried everything, deleted all vpn apps, disabled private addresses etc. none of them helped me.

i saw in an entry that setting manual dns could help and did this. I defined google dns for my home network and it did work. Now I can use my iphone at home without any wifi interruptions.

RS.

Umfortunately not an official one. Apple and their supporters still claim that it is not a bug. I have found a workaround. In WiFi networks which ios 14+ shows with weak security, I change "Configure DNS" to Manuel and enter Google DNSs, as 8.8.8.8 and 8.8.4.4. This solved my all problems, hope works for you too.

I appear to have fixed the problem for me. I think 14.0.1 is a lot more sensitive to WiFi configurations than before.

I noticed that the dropouts were considerably worse in one area of our house.

Our WiFi setup is a Ubiquiti network. This has 4 Unifi mesh network access points. I noticed the firmware version of the Unifi in the area with more dropouts was older than the other Unifi modules. I updated all the Unifi modules and the Ubiquiti switch to latest firmware and now (3 hours in so far) I am not having any dropouts.

So, I suggest everyone checks and updates the firmware of their WiFi equipment.

Good luck, and I’m keeping my fingers crossed here.

Restoring your phone won't fix the issue if it's a bug in 14.0.1. I actually updated my phone from a restore. If you want new software I would try getting the 14.2 beta (beta 2) if your still having problems. Also have you tried turning off WiFi assist?

I had the same problem as well. I did not have Bitdefender either however my ISP provides Macafee security and it was for some reason trying to open a VPN connection. Maybe it uses it to connect but not sure at this point. I just disabled my VPN in settings and problem is gone. I did notice that before I turned VPN off I would see a very small VPN flash in upper right hand corner of iPhone screen that I hadn’t seen before. That was my clue.

I believe the only global “solution” is what I’ve posted above, which in short entails completely resetting the device and setting it up as a new iphone/ipad, ie WITHOUT restoring it with your backup. The problem is somewhere within the software, so the problem will be migrated back into the device again...

I am having the same issue and the only thing that seems to work is to change the the DNS settings to Manual and add a dns server 8.8.8.8 or any other dns server in your region. This bug is really frustrating and expecting more from Apple

After waiting AND hoping for an update that never came. RESET. .No backup restored. Worked for me..

Authenticators and lots of apps reinstalled. 6hours later and I am half way.

Had to call (Nice waiting tune) the ING creditcard company.,

They had to manually reset my account.

Dear Apple this BUG cost me a lot of time.

Not a happy Apple customer.

Riotten22 are you using a vpn? What ISP are you using? Some providers offer antivirus free but they use a VPN to do it. Mine was Cox and went to my settings and deleted the cox VPN. Haven’t had an issue since.
