Purchased the unit about three weeks ago. Updated to the newest firmware because I was having trouble getting my machines to connect. Seemed to work better. About hourly the router will require rebooting to start working again. Any help? Ideas?

- Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.
- What region are you located?
- Has a Factory Reset been performed?
- Was a Factory Reset performed before and after any firmware updates?
- Was the router working before any firmware updates?
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 (http://forums.dlink.com/index.php?topic=53008.0)
- 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 (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) 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 (http://forums.dlink.com/index.php?topic=53222.0)
- 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 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 (http://forums.dlink.com/index.php?topic=48695.0) feature. Tools/Time.
- Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
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)
- 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 (http://en.wikipedia.org/wiki/Wireless_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 (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.
- What wireless devices do you have connected?
- Any cordless house phones?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) 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, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
- Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.
How close are other devices to the router?

I have the same problem with newest firmware 1.02. My wired network (through dir-868l) is fine, but the wireless network keeps dropping (required a reboot to work again). I re-uploaded the firmware 1.02 (tried both with reloading configure and manually re-set) many times even download 1.02 twice, but it didn't work. Back to 1.01, everything is OK again.

I'd like you to run thru the list if suggestions and questions I presented to you in that thread or this thread and copy and paste back your results here and let see if we can figure this out. I haven't had any issues with my 868L wireless and just yesterday I put it online in AP mode and connected a DIR-865L in bridge mode to it. A xbox 360 is connected to the 865L. Gaming for roommate was great. This is on the 5Ghz AC mode on the 868L. 2.4Ghz is shut off currently as I'm testing a different router with 2.4Ghz and a DAP-1533 for a different thread.
I also recommend turning OFF ALL wireless devices and then turn on 1 device and start testing. Graduate adding 1 more device. Keep doing this until you notice anything or something. Shut OFF the printer as well.
Please let us know results of the wireless suggestions and questions in the thread.
Maybe someone can review your router settings with you using Link> teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.

Sorry for not answering a long time. I'm very busy now. The firmware 1.01 is fine for now. I'll do what you said when I have time but not now. Thanks a lot.
