Hello, I have the DIR-655 Hardware Version: B1 running Firmware Version: 2.11NA, and for as long as I can recall I have been getting painfully slow internal transfer speeds. From wired to wired I manage 8-12MBps, and from wired to wireless 1-3MBps. Wireless to wireless I get <1MBps.

I have been pulling my hair out trying to figure out why the performance is so slow but have been unable to resolve it. Is there anyone who can help me figure this out?

Link>Welcome!

• 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?

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. For the DGL-5500, review this for Streamboost information and settings: Furry's DGL-5500 Review
• 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 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 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 and Wired devices, swap out to be sure. Link> Cat6 is recommended.

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 LAN PC while testing.
• Disable any downloading client software managers, i.e. Torrents or similar.

Also the addition of installing a external Gb network switch between the router and wired LAN devices is recommended.

Thanks!

I am in Canada, and have performed factory resets before and after upgrading firmware.

I have a cable 30Mbps service, and do get the full 30Mbps more often than not. I have a DCM476 modem.

I have also tried every suggestion you've posted as I've been lurking on these forums for a while trying to solve this issue. Nothing I've found posted here has been of use unfortunately.

Installing a external Gb network switch between the router and wired LAN devices is recommended.

That wouldn't help my <1MBps wireless speeds though. Is there nothing I can do short of getting a new router?

[FurryNutz]

Give the external Gb switch a try.

Wireless, make sure your any adapter drivers are up to date for those devices that have those.
Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

• 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 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 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 or ON Short GI, WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
