Title: DIR-655 and DAP-1522 (bridge mode) issues
Post by: grishnak on June 05, 2013, 12:27:31 PM

Hi,

I am having issues with my DIR-655 (HW v.B1) and DAP-1522 (HW v.A2) as a wireless bridge at home. I have had this configuration for several years without any issues.

However, some months ago the DIR-655 started to fail, freeze and restart itself at random situations. After several troubleshoot attempts and consulting with others, I decided to get a new DIR-655 (HW v. A4).

Using the same configuration (as far as I can remember) as before, I can't access the internet with a PC via cable through the DAP-1522. I have looked through other issues people have with these two units and have tried to test various suggestions given to them.

I know I can get the DAP-1522 to connect to the DIR-655. I know this since besides seeing this in the Wireless Status of both units, when I connect a PC via cable to the DAP-1522 I can access the admin interface of the DIR-655. However, as I mentioned - I can't access the internet.

Any ideas or suggestions would be greatly appreciated!

Thanks!

• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) versions is currently loaded? Found on router/DAP web page under status.
• What region are you located?
• Has a Factory Reset been performed and then set up each again from scratch?

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. Rev B Routers only.
• 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.

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 Routers only: Try single mode G or N or mixed G and N?
• 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.
• Any cordless house phones?
• Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
• Try turning off Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
• Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.

3rd Party Security Software Configurations

• Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
• Turn off all devices accept for one wired PC while testing.

I think there was talk of Rev A DAPs not working correctly with Rev B routers. Or vice versa. Something to do with the Draft N and Certified N not being compatible.
