Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesIf Wi-Fi is slow only on your iPhone, compare it with another device on the same network, then try the iPhone on a different Wi-Fi network. If the slowdown follows the iPhone, check its software, VPN or security filters, and Wi-Fi settings. If it stays with one network, look at the router, signal, and internet service.
First, pinpoint what is actually slow
Note whether the problem is slow web pages, streaming, downloads, or joining or maintaining a Wi-Fi connection. Check that the iPhone is connected to the expected Wi-Fi network and whether cellular data appears to be in use. A Wi-Fi connection and an internet connection are not the same thing: poor signal, router congestion, DNS or VPN filtering, and an internet-service problem can all feel like “slow Wi-Fi.”

Use two comparisons to locate the problem
- Try another device on the same Wi-Fi. If it is slow too, the iPhone is less likely to be the only cause. Investigate the router, local network, or internet service.
- Try the iPhone on a different Wi-Fi network. If it works normally there, focus on the original network. If it is slow across unrelated networks while other devices work, focus on the iPhone or its settings.
Apple recommends checking other devices and trying another location or network to distinguish a device issue from a network-specific one. Apple’s iPhone Wi-Fi troubleshooting guide
If the problem follows the iPhone
Restart and update iOS
Restart the iPhone and install any available iOS update. These are sensible first checks for connectivity problems before changing network settings. Apple’s connectivity troubleshooting guidance
#1 Best Overall
- DUAL-BAND WIFI 6 ROUTER: Wi-Fi 6(802.11ax) technology achieves faster speeds, greater capacity and reduced network congestion compared to the previous gen. All WiFi routers require a separate modem. Dual-Band WiFi routers do not support the 6 GHz band.
- AX1800: Enjoy smoother and more stable streaming, gaming, downloading with 1.8 Gbps total bandwidth (up to 1200 Mbps on 5 GHz and up to 574 Mbps on 2.4 GHz). Performance varies by conditions, distance to devices, and obstacles such as walls.
- CONNECT MORE DEVICES: Wi-Fi 6 technology communicates more data to more devices simultaneously using revolutionary OFDMA technology
- EXTENSIVE COVERAGE: Achieve the strong, reliable WiFi coverage with Archer AX1800 as it focuses signal strength to your devices far away using Beamforming technology, 4 high-gain antennas and an advanced front-end module (FEM) chipset
- OUR CYBERSECURITY COMMITMENT: TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Secure-by-Design pledge. This device is designed, built, and maintained, with advanced security as a core requirement.
Temporarily test VPN or security filtering
A VPN or third-party security app that monitors or filters connections can interfere with some connections. Apple recommends removing the software for a test, restarting, and checking again. If the connection improves, contact the software provider or administrator rather than leaving a required protection tool removed. For a work- or school-managed iPhone, ask IT before removing managed software or settings. Apple’s Wi-Fi troubleshooting guide
Review settings for the affected Wi-Fi network
Open Settings > Wi-Fi, then tap the information button beside the network. Check DNS, HTTP Proxy, and Low Data Mode. If DNS or proxy details were set by an employer, school, provider, or network administrator, find out why before changing them. Apple documents these settings in its Wi-Fi settings guidance.
Rank #2
- Dual-band Wi-Fi with 5 GHz speeds up to 867 Mbps and 2.4 GHz speeds up to 300 Mbps, delivering 1200 Mbps of total bandwidth¹. Dual-band routers do not support 6 GHz. Performance varies by conditions, distance to devices, and obstacles such as walls.

Leave Private Wi-Fi Address enabled by default. It uses a private address for a Wi-Fi network to help reduce tracking. Turning it off is not a general speed fix; consider it only if a specific network’s administrator identifies a compatibility or authorization issue, and understand the privacy trade-off.

Connectivity Assist can use cellular data to improve an internet connection when Wi-Fi is slow or unusable, which can make a weak Wi-Fi connection seem better than it is and increase cellular data use. Apple’s current guidance places the setting in Wi-Fi settings and says it supersedes Wi-Fi Assist on updated software. Check whether cellular data is being used when comparing performance.

On older software, Apple’s Wi-Fi Assist documentation describes restrictions, including foreground-use behavior and exceptions for certain apps. Do not assume every app or background download will switch to cellular. Apple: About Wi-Fi Assist
If the problem stays with one Wi-Fi network
Check coverage, router, and internet service
- Try the iPhone closer to the router. If performance improves, range or obstacles may be involved.
- Restart the router and modem, and check whether router firmware is current.
- If the router offers separate Wi-Fi bands, compare them. Apple uses 2.4 GHz and 5 GHz as examples in its troubleshooting guidance; the best result can depend on range and the network environment.
- Check that the router supports the Apple device. Apple’s router recommendations also address radio modes, security, DNS, and NAT.
- If all devices have trouble reaching the internet, contact the internet provider. If this is a hotel, school, workplace, or public network, contact its administrator if you do not manage it.
For router settings, Apple recommends enabling WMM; it warns that disabling WMM can affect performance and reliability. Avoid changing advanced controls unless you know how to restore the original settings. Apple’s recommended settings for Wi-Fi routers and access points

Match the symptom to the next check
| What you observe | Where to investigate | Next step |
|---|---|---|
| Other devices are slow on the same Wi-Fi | Router, coverage or interference, local network settings, or internet service | Restart and update the router, compare available bands, and contact the network administrator or provider. Apple Wi-Fi troubleshooting; Apple router guidance |
| The iPhone is slow on several unrelated Wi-Fi networks | iPhone software or settings, VPN/security filtering, or a device issue | Restart and update iOS, test without VPN or filtering where appropriate, and contact Apple if the problem persists. Apple connectivity troubleshooting |
| Only one app seems slow | App or service behavior, VPN/filtering, or DNS may be involved; the symptom alone does not identify the cause | Compare another app and another Wi-Fi network before resetting settings. |
| Wi-Fi seems slow while cellular works | Weak Wi-Fi or a network-side issue; cellular fallback may obscure the difference | Check signal and per-network settings, and watch for cellular data use. Apple Connectivity Assist guidance |
| The iPhone has trouble only on a network that identifies or controls devices | A private-address compatibility or authorization issue is possible | Keep Private Wi-Fi Address on unless the network administrator identifies a specific reason to change it. Apple Wi-Fi settings guidance |
Save Reset Network Settings for last
Reset Network Settings is more disruptive than restarting or checking an individual Wi-Fi network’s settings. Apple says it removes saved Wi-Fi networks and passwords, along with cellular, VPN, and APN settings. You may need to rejoin networks and restore required settings afterward. If the iPhone is managed by work or school, consult IT before resetting. Apple’s reset and troubleshooting guidance
