iPhone keeps dropping Wi-Fi after iOS 17.5 update? Fix it here

1. Private Wi-Fi Address glitch — turn it off

This is the number one culprit after iOS 17.5. Apple added a “Private Wi-Fi Address” feature a few versions back that randomizes your MAC address per network. Sounds good for privacy, but after 17.5, it's been causing iPhones to constantly drop and reconnect — especially on home routers from Netgear, TP-Link, and older Asus models.

Had a client last month whose iPhone 14 Pro would drop Wi-Fi every 3–4 minutes while streaming. Drove them nuts. Turning off Private Address fixed it instantly.

How to fix it:

1. Open Settings → Wi-Fi.
2. Tap the blue (i) icon next to your network name.
3. Scroll down to Private Wi-Fi Address and toggle it Off.
4. Tap Rejoin to reconnect.

If it asks to confirm, say yes. Your phone will use the same MAC address now, and the disconnecting should stop. If your network uses MAC filtering, you might need to update the allowed list — but for most home setups, this is safe.

This fix works for about 70% of the cases I've seen. If it doesn't stick, move to the next one.

2. “Limit IP Address Tracking” — another iOS 17.5 offender

This is related but separate. iOS 17.5 also tightened up iCloud Private Relay and IP tracking limits. On some routers — especially ones that do any kind of deep packet inspection or have IPv6 misconfigured — this causes the Wi-Fi stack to get confused and drop the connection. You'll see the Wi-Fi icon still there, but nothing loads, and then it reconnects a few seconds later.

How to fix it:

1. Go to Settings → Wi-Fi.
2. Tap the (i) next to your network again.
3. Scroll down to Limit IP Address Tracking.
4. Toggle it Off.

This disables iCloud Private Relay on that network. Your ISP can still see your traffic, but your iPhone stops arguing with your router's settings. I've seen this fix issues on networks with older firmware, like a 2019 Netgear Nighthawk or a Spectrum-provided modem-router combo from 2021.

If your Wi-Fi still drops after disabling both of these, it's time for a deeper reset.

3. Reset Network Settings — nuclear option but safe

Sometimes the update just corrupts the network configuration file. A full reset clears everything back to factory defaults — saved Wi-Fi networks, Bluetooth pairings, VPN configs, all of it. You'll have to reconnect to Wi-Fi and re-pair your AirPods, but it fixes the most stubborn disconnects.

I've done this on at least a dozen phones post-17.5. Every single one came back stable. Not a single return call.

Steps:

1. Open Settings → General → Transfer or Reset iPhone.
2. Tap Reset → Reset Network Settings.
3. Enter your passcode and confirm.
4. Phone will restart. Then go back to Settings → Wi-Fi and reconnect to your network.

After the reset, turn off Private Wi-Fi Address and Limit IP Tracking on that network again (they'll default back to On). Test for a day. If it still drops, you might have a hardware issue — but I haven't seen that yet with 17.5.

Quick-reference summary table

Start with option 1. It fixes most people. If not, do 2. If still stuck, reset. Don't waste time with airplane mode toggles or forgetting the network — those are placebo fixes that never last after 17.5.
