Hello all.
I bought a few days ago the D-Link DIR-860L AC 1200 router, 4 x Gigabit LAN, USB 3.0, set up, set off ... all good. On my phone (LG V20) work both networks, on another android goes well the 2.4 network, the problem is on a Lumia 540XL (windows phone) that goes very badly network, barely connects and sometimes does not see it at all. I tried different settings on 2.4 network, sometimes it went, sometimes not ... it's not working more often. I noticed that it started to lose networks, when 2.4 when 5 ... at configuration appeared that the network are ok. Frequently the speed is fluctuating. I tested it with the old router and it works perfectly on the 540 XL network, so it's not problem with the phone.
Data from the router: current Firmware Version: 2.03, Current Firmware Date: 2015-04-20 16:35:00, on the paper on them is B1 / 2.03
I have a PPOE connection at 300 mb (romania) speed and I have the following speeds (phone beside the router):
- 5: U-92 Mbps, D-84 Mbps
- 2.4: U-0.94 Mbps, D-0.84 Mbps (at that time)
On both networks all settings are on auto. Please have anybody have these problems and can help me with some advice. My brother has the same router model and works very well. I want to know if there is a problem with settings, software or is a problem with the router, I give it to service or replace it with another mark ...
I tryed to change settings on both networks but not working
Thank you.

• What region are you located?

Are wired speeds good?

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. Be sure to log into the Admin account on the router.

• Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
• 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.
• Turn on or off DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
• 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.
• Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.
• Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
• Turn off WISH, and WPS under Advanced.
• WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed

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.
• 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.

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Romania, i have 300 Mbps PPPoE connection.
I replace the router with a new router same model. Still have same problems...Slow speed in another room at 2.4, lose connection, very unstable. I try to change settings like you tell me, no result. I cannot understand what is the problem with this router...
Tomorrow i will give back the router and take from another producer.
