Recommended settings for Wi-Fi routers and access points - Apple Support

If your WiFi has been set-up according to Apple’s recommended settings, WiFi and Internet connection difficulties are usually an indication that your device does not have a routable IP Address - your IP Address usually being assigned by DHCP. When this occurs, your iPad may only have a self-assigned link-local IP address that begins 169.254.x.x.

If you have a VPN App or profiles installed, or a security App such as Norton, these may be interfering with DHCP and preventing your device from obtaining a valid IP Address for your iPhone hotspot - or the WiFi network to which you are attempting to connect. The resolution is usually simple; if installed, you may only need to temporarily disable or remove the Security App and/or VPN.

DHCP is frequently used to automatically obtain an IP Address. Until your iPad has a valid IP Address to connect to your network, you will not have an internet connection. Disabling or removing VPN and/or the offending security App should allow DHCP to operate normally - allowing connection to your network and the internet.

If this resolves your issue, the VPN and/or security App can be reinstated after the connectivity problem has been resolved.

If your Internet service is the newest of WiFi connection standards, a 10-year old iPad may not be able to connect.

Other possibilities.

Make sure however you connect to WiFi has the sane user login ID and password settings on what it is that allows yoo to connect your iPad to a WiFi netwotk

If these have changed, your iPad will no longer connect and be able to access the Internet.

If you have a home wireless, WiFi/MODEM network box, you will need to find the instructions for this box so you can enter that box's internal software to check security/firewall settings and set those settings for less strict security settings to allow your device to connect.

Also, to be able to confirm wireless network login ID and password settings, as well.

You might be able to get help from your Internet service provider to try and help you with your device connections issues if this is all beyond your knowledge.

Since you own such an old device,

It may become necessary to try and change the DNS server settings on both your MODEM/router ( consult your MODEM/router instructions to access its software ) and/or on your iOS/iPadOS device.

For recommended DNS servers (to be configured at your home MODEM/router and/or your iPad), you can choose from one of the following Recursive DNS Provider numbers below.

Quad9 (recommended)

9.9.9.9

149.112.112.112

2620:fe::fe

2620:fe::9

OpenDNS

208.67.222.222

208.67.220.220

2620:0:ccc::2

2620:0:ccd::2

To change the DNS server settings on any iOS/iPadOS device, Go into the Settings app under the WiFi Settings panel, tap small round blue colored circle with an “i” inside of it, shown next to your home WiFi MODEM/router network name, to get info on your home WiFi Network info.

Then, scroll down to where is shows DNS

Tap the gray colored disclosure triangle at the far right of the settings panel immediately below.

If under automatic, somwhere on this page, if you see any other recursive DNS server settings listed, try one of those.

If not, tap to check the Manual setting and input or copy/paste one of the recursive DNS server addreses I have listed above.

See if this solves your WiFi connectuon issues.

If not, there is really not much left to do or try and you may need to consider a purchase a new or “newer” used or refurbished iPad model that is more current and supported on the latest iPadOS operating system.

Apple is up to iOS/iPadOS 15.7 and iPadOS 16 will be released sometime in October 2023.

iOS 9 and 10 devices are completely unsupported and obsolete and have been for quite a few years.

There is NO MORE third party app support for these 10 and 11-year old iPad models, any longer.

Also, FYI, if using any Web browser from the 2016/2017 time peroid, these old iOS Web browsers are no longer safe NOR secure to be trusted, any longer, on today’s Internet.

Apple has NOT issues any security updates for such old devices in many years!

Best of Luck to You!
