”Weak Security”, you have WPA, you should use WPA2 etc.

iPadOS14 produces these information messages to indicate that the security settings are less than ideal.

This support page will describe the more secure (recommended) settings for WiFi:

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

It is possible that your WiFi Router is too old for you to be able to set more secure settings on the router - so you can either configure the most secure settings that your Router will support, or update your Router for something that provides better security features.

We have ADSL and the modem/router is 3 years old; we also do not have a choice re. that hardware: it was (still is??) the only one for a DSL line from our provider. The highest security setting is WPA2 Personal. I contacted them today to see if there is a more up to date router I can buy. Have not heard back.

It isn’t always necessary to update your ISP-provided router. Many have no alternative other than than to use the ISPs router/modem. The easiest (and often best) way to upgrade your home WiFi is to add either a more sophisticated WiFi Access Point (AP) - or a WiFi Router of your choice that is configured in “bridge mode”.

Of available choices, the Uniquity AmpliFi series of devices are currently very popular.

Thanks, will check that out after talking to the ISP as there also appear to be some download speed problems: am supposed to get 20M, but on the modem website, it shows 11. Regularly have problems with movie streaming mostly where audio suddenly lags way behind the video or just quits altogether.

Check the setting on your router. How you do that varies by router brand/model.

If WPA2 is the best that is available in the modem/router settings, contact your provider and ask if they have a more up to date modem/router available. Apple currently recommends WPA2 (AES) or WPA3.

Always my pleasure to help 🙂
