I have 2 of these DIR-816L router with hardare version B1 and firmware 2.06 (different home)

Issue: Device needs to disconnect from wifi and reconnect again to have internet.

I noticed that if my device (e.g. iphone, ipad, laptop) is connected to wifi for too long, there will be no more internet connection but able to login to admin page 192.168.0.1.   
Solution is for the device (iphone/ipad) to disconnect wifi or switch from 2Ghz/5Ghz and then it will have internet again.

This is happening to both DIR-816L.  most likely a firmware issue.

Link>Welcome!

• What region are you located?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• 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.

• Enable or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
• Setup DHCP 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.
• If IPv6 is an option on the router, select Local Connection Only under Setup/IPv6.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• 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 to find out. How many?
• If you have any of these options, Try turning OFF or ON Short GI, 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.

• What Hardware version is your router? Look at sticker under the router case.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?

What is the Mfr and model of the main host router and ISP modem?
Please provide feedback to my original post and give answers to some of the questions presented.

After 10 months, I gave up, my solution was to replace 816L router
http://forums.dlink.com/index.php?topic=66057.0

@Furry, I followed your suggestion. nothing worked and 99% of my wifi-device have difficulty on reconnecting.

816L wifi disconnect issue can easily be reproduced: (happens everyday to me)
1. Rev B, firmware 2.06
2. Restart both modem and 816L router same time.
3. wireless clients (e.g. iphone on iOS8,9,10 and HP laptop) will loose wifi connection and cannot reconnect to 816L
4. Temp solution:  On iPhone, manually switch to another SSID (if on 2.4ghz of 816L, use the 5ghz, or vice versa)
5. Temp solution to switch WIFI network need for Apple TV3.  toooo cumbersome and some people (old folks) dont  know how to  switch wifi network.

What wireless modes are you using on the router? Manual mode is recommended. Same goes for security mode, manual WPA2 and AES only, not mixed.
If you have 5Ghz supporting devices, 5Ghz can be used more often than 2.4Ghz.

Using only wireless-N WPA2 and AES (no TKIP for this router), tried hardcoding to Channel 1 / 6/ 11 or Auto, 20Mhz.
2.4Ghz and 5Ghz have both the same issue.

Not using torrent, just few clients - apple TV3 , 2 iphone, 1 ipad, 1 laptop, 2 ip cam that is barely active, 1 nas.

dir-816L replaced my aging dir-655.  it was a regret
