Wi-Fi password requirements for same SSIDs and non-Apple device negotiation on TP-Link router

After receiving alerts that my WiFi had 'limited compatibility' when connecting iPhones, I used Apple's "Recommended settings for Wi-Fi routers and access points" (Recommended settings for Wi-Fi routers and access points - Apple Support )to update the settings on my TP-Link router (BE19000 Tri-Band Wi-Fi 7 Router).


Apple's instructions specified that all WIFI SSIDs have the same name, but mentions nothing about the passwords. Using the same name for all SSIDs seems strange to me but I will keep the same names and assess performance over the next few days.


My questions are:

Since the SSIDs have the same name, are the passwords also required to be the same?


How will non-apple devices negotiate wifi access points and are there any other settings to consider?

Yes, the passwords for all SSIDs must be exactly the same if they share the same name (SSID).


Non-Apple devices (Windows, Android, smart home tech) handle unified SSIDs using industry-standard protocols, though their success depends on how modern the device is.


  • Modern Devices (Android/Windows): They negotiate the network similarly to Apple devices. They will look at the signal strength (RSSI) and the capabilities of the band, usually preferring the faster 5 GHz or 6 GHz bands when close, and dropping to 2.4 GHz when far away.
  • Older or Legacy Devices: Some older devices (especially cheap 2.4 GHz smart home electronics like smart plugs or older printers) can get confused during setup if the 2.4 GHz and 5 GHz networks share a name. They may fail to connect because their Wi-Fi chips cannot process the multi-band broadcast properly.

All passwords for the SSIDs will need to be the same. (This if you’re not also running PPSK or 802.1X RADIUS authentication, which can be configured to have per-client or per-person credentials for network connections.)


You’ll want one IP router too, and either that router and access points, or a separate router and all access points, or a mesh network. (More than one IP router is possible, but has some configuration requirements, and usually trades off AP or mesh roaming.)


You’ll probably need WPA2-WPA3 transitional, or all WPA3. WPA3 and 6 GHz go together.


It is also possible to run multiple SSIDs and each SSID with the SSID-specific password, and to tune (or de-tune) one for IoT and gear that might be incompatible with 5 GHz or WPA3 or whatever, or less than robustly secured and less than trusted. Downsides include more channels used, and probably VLANs.


Random Wi-Fi trivia: 1: it’s easy to make a QR code for a guest network. 2: Apple also makes sharing SSID and password easier.

Thank you, WheelieNick.
