Hi
I have a 655 with a few PC and a NAS attached on ethernet, and a Raspberry Pi plus Android phones on the wireless network (all with fixed addresses reserved in dhcp).
The problem initially was that the XBMX remote control software on the phones could sometimes not connect to the xbmc server on the PI. So I put a PING tool on the phones, and found that sometimes, it was impossible to ping the PI, even though the PI and the phones were happily playing content from the web and from the NAS device. I also found that sometimes the phones could not ping each other - in each case the result was 'no route to host'. I also tested from one of the PC, and found the same problem: sometimes it is impossible to ping the PI. In one test, I had ping running on the PC (no reply) and then used the PING tool built into the router. As soon as I started that to the PI, it worked, and the connection from the PC started working at the same time.
The router is running 1.37 NA, with WLAN partition set to OFF.
Any suggestion?
Thank you

- What region are you located?
- Was a Factory Reset performed before and after any firmware updates then set up from scratch?
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.
- 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.
- 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.
- 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.
