The Graveyard - Products No Longer Supported => Routers / COVR => DIR-868L => Topic started by: tm07x on December 25, 2014, 06:51:08 AM

I've encountered to strange problems with the 868L. 1st being that the WAN keeps dropping out for a few minutes and the second, unusually high latency before devices connect to source. E.g Bose Soundtouch internet radio takes forever to load a channel and both xbox and ps4 have problems with high ping and connections.
When watching netflix on whatever device, TV, computer, xbox etc, it will disconnect every 2 hours and stay off for a few minutes.
I run one TV, Xbox and computer on WIRED lan. And I have tried disabling wifi all together and run LAN only but the problem still persists. The Bose soundtouch has same problems over wifi as over LAN.
I have tried firmwares 1.04 to 1.09 and YES, I have followed the instructions. Factory reset, etc etc etc.
I have even tried US firmwares on this EU model to no avail.
This is NOT a wifi issue. For the record, there is zero to little congestion in my area.
I have tried different Cat cables, rated from Cat-5 to Cat-6b, the problem is still the same. I have tried multicast settings, dhcp, disable upnp etc but pretty much all that I've tried doesn't work. The ISP has done a reset on their end, assigned me a new IP, I have done a modem reset and they have boosted my signal + increased my speed from 50 to 100mbps. The xbox connects fine when directly hooked up to the Cable Modem and there are no latency issues, same goes for netflix to TV and Bose internet radio.
I tried an Asus RT-68U and it does not give me the same latency + intermittent disconnecting issues. Again, the disconnections are NOT wi-fi related.
Asus 868L EU model - Rev A.
I have also tried disconnecting wifi + all LAN devices but one, and the problem is still there.
Any solution guys?

- What region are you located?
- Are you wired or wireless connected to the router?
- Was the router working before any firmware updates?
Please use your regional FW version, do not use cross regional FW version as they do differ.
Internet Service Provider and Modem Configurations
- What ISP Modem Mfr. and model # do you have?
- Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
- Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
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.
- 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 OFF DNS Relay (http://forums.dlink.com/index.php?topic=45143.0) under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0) and input new DNS addresses under Setup/Internet/Manual.
- 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.
- If IPv6 (http://en.wikipedia.org/wiki/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 (http://en.wikipedia.org/wiki/SPI) to test.
- Enable uPnP (http://en.wikipedia.org/wiki/Upnp) and Multi-cast Streaming (http://en.wikipedia.org/wiki/Multicast) under Advanced/Networking. Disable uPnP for testing Port Forwarding (http://forums.dlink.com/index.php?topic=4235.0) 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 (http://forums.dlink.com/index.php?topic=40459.0), 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 (http://forums.dlink.com/index.php?topic=48695.0) feature. The DST setting is only needed in the NA region. Tools/Time.
Wireless Configurations
Links>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0) and Managing Signal Congestion (http://forums.dlink.com/index.php?topic=53228.0) and Good Neighbour Policy (http://forums.dlink.com/index.php?topic=10634.0)
- Ensure the default (dlink) SSID name is changed. Can be anything and not something that's 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 or AC on 5Ghz?
- 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. 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 (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?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.techspot.com/downloads/5936-inssider.html) to find out. How many? Use v3, its free.
- 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.
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.

Like I wrote in the previous post.
Europe.
This is for wired connections. That being said, switching to wireless, or turning off wireless does NOT resolve the problem.
No, it has always had intermittent disconnecting problems. Upgrade - downgrade, you name it, it still doesn't work!
I use regional FW version, and have even tried other firmware solutions to no avail.
The modem is a bone stock Thomposon Canal Digital modem, and this is the second modem they've sent me so it's NOT the modem.
Again, there is NO latency and ping problem when going directly through the modem OR when I use an Asus router. There are no cable issues either.
MTU is 1500 which also happens to be stock for Cable.
In plain english, it's a ROUTER issue - NOT a modem, computer or other issue. The problem has been isolated to a router issue and all aforementioned solutions and settings have been tried and none fix the problem.
Seems to me there is an internal routing issue that the router can't handle. Which is why services like Xbox Live, PSN, internet radio etc have insanely long connection and ping times compared to the Asus router.
In truth an incredibly horrendous product if I must say so.

Ive never had any issues with my 868L and believe it's one of D-Links better routers. Its solid and works great.
I believe in this case, that you may have a faulty router and would just need to be RMAd. I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.
