Yes, had DNS relay enabled. Never thought of disabling it until I got the new one. Still have the old one here.

Same thing happened today. Everything was working fine until i started using my MacBook. If my MB stops the internet connection, it needs to be an issue with the router, doesn't it?

[FurryNutz]

What OSX version are you using on the Mac Book? I haven't seen any issues with my OSX 10.7.5 or 10.8.3.

Ensure the Mac is getting a valid reserved IP address.

Something between the Mac and the router. I presume something maybe on the Mac.

You might reset one of the old 865s and see if by turning DNS relay OFF resolves that problem.

Hello,

I'm suffering the same behavior.
Router can work as espected for two or three days, but after that, it lost internet conexión and reboots automatically ones and again.

It's connected to a Thomson cable-roter TCW 770 that works perfectly.

My ISP is Euskaltel and it gives 3 public IP per cable conection (TCW 770).

This is an arquitecture overview:


                                               ISP
                                                  |
                                                  |
                                        ---------------
                                        | TCW 770 | (Configured as Bridge)
                                        ---------------
                                           |           |
                            (for LAN) |           | (DMZ)
                (dhcp1 from ISP)|           | (dhcp 2 from ISP)
                                           |           |
                           ---------------     -------------
   (WAN: dhcp-c) | DIR-865L |     | SERVER |
    (LAN: dhcp-s) |                 |     -------------
                           ---------------
                             |    |    |    |
               (LAN clients, wired & wireless)


Where:
   dhcp-c = DHCP client
   dhcp-s = DHCP server

Has anyone any idea of how to solve my problem?

Thanx in advance.

Link>Welcome!

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

What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values

Ok, so after monitoring it over a couple of weeks I can now say for sure that it's my MacBook that's wrecking the network. I've had the network stable over several consecutive days without any issues - all up until I turn on my MacBook. Then it takes a couple of minutes and all internet traffic stops until I reboot the router.

I've had multiple iPhones, an iPad, and Apple TV, an Xbox 360, a Windows Server 2012 and a Windows 8 laptop running fine for several days as long as my MacBook is shut down.


The MacBook is running OS X 10.8.3 with all the latest software updates. It's set up using DHCP but with a manual IP address. I thought I already had reserved the IP on the router, but that was probably on one of my old routers. However I've reserved it again on the new one now.

What on my Mac can be causing this?

[FurryNutz]

Hmmm...I use the same OSX version and don't see this issue. However My MBP is a 2007 edition so a bit older. What year is your model?

This happens both wired and wireless?

I set the OSX networking for Automatic and reserve the IP addresses ON the router for the wired and wireless connections on my Mac. So there are 2 reservations.

[toeggi]

It's a MacBook Air 13" Mid 2011 model. I haven't used a wired connection in a while, but I will definitely check next time.

I'll set my MB to automatic IP and keep the reservation on the router only and see if that makes a difference.

[FurryNutz]

Ok, Does the air come with a LAN wired connection? 

Keep us posted.

No, but I have both a USB and a Thunderbolt to ethernet adapter

Will do!

[FurryNutz]

Any status on this?

Anyone has resolved this issue?

I have the similar issue.  I have many devices eg. Ipads, androids mobile, macbook air, iphones and MBP.

Only 1 particular MBP will cause Internet connection unavailable whenever i used it for a while eg. 10mins or so.  I need to reboot the router to make internet available again.

Link>Welcome!

I haven't seen any issues with my 865L. I had it online for a couple of weeks and is a solid router. I have a few WiFi devices and also do gaming on it as well. Lets see if you can provide some answers to some of the questions and lets see if we can help you get yours going...

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• 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?
• What ISP Modem service link speeds UP and Down do you have?
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

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.

• Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS or Gamefuel.
• 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 Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
• Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
• 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.
• Ensure devices are set to auto obtain an IP address.
• If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options 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
• Set current Time Zone, Date and Time. Use an NTP Server feature. Tools/Time.
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

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

• Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N 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.
• 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?
• Any 2.4 or 5Ghz cordless house phones?
• Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
• If you have any of these options, Try turning OFF  Short GI, WLAN Partition, HT 20/40 Co-exhistence and Extra Wireless Protection if you have it. 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."
6" minimum safe distance between devices.
