Title: Apple iOS Devices disconnect from router on occasion
Post by: Ekerstan on October 13, 2016, 07:44:00 AM

I have a strange issue that comes up about every 10-14 days.  What happens is that on occasion all my Apple iOS devices will get disconnected from WiFi all at the same time.  When I attempt to reconnect in the device settings, it will cycle quickly between reconnecting and disconnect, however it will never reconnect.  The fix I've used to get them reconnected is to power cycle the router.  Then they will connect fine and remain connected until it happens again about 10-14 days later.  As I mentioned this only happens with Apple iOS devices, all other types of computers or devices using WiFi are unaffected.

What makes it even more puzzling is that recently I found that if I power up my MacBook Pro and connect to the WiFi when this occurs, it will connect fine and then I'm able to reconnect my iOS devices again.  I don't need to power cycle the router as I've done in the past.

Any help would be appreciated.

• What region are you located?

What iOS versions are currently loaded on the Apple devices?

• Has a Factory Reset (http://blog.dlink.com/what-is-a-reset-button-when-should-i-use-it) been performed?
• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

• Was the router working before any firmware updates?

Internet Service Provider and Modem Configurations

• What ISP Modem Mfr. and model # do you have?

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.

• Setup DHCP (http://forums.dlink.com/index.php?topic=58017.0) reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
• Ensure devices are set to auto obtain an IP address.

Set IPv6 to Local Only Connection.

• Turn off WISH (http://forums.dlink.com/index.php?topic=40459.0), and WPS under Advanced.

• Try single mode G or N does the same thing happen?
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner (http://forums.dlink.com/index.php?topic=48327.0) to find out. How many?
• If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.
