I was given a DIR-615 which I reset to factory defaults - I have a cable internet connection, with two computers running off the router. One runs Windows XP, the other Linux.
When setting up router, should I clone each PC's MAC address or leave it as it was when the router was connected to the modem and both rebooted ??

I did clone my MAC address on the Linux machine and it still worked....when I did that to the Windows machine it no longer had internet access. Should I have rebooted everything again ?

For now I reset factory defaults, rebooted the router and modem and it's working again. But both machines have slow access when they are both on...sometime so slow Chrome times out...other times we wait a long time to get to some webpages.

There are too many things to setup 
Thanks for any help

No need for MAC Cloning.

What Hardware version is your router? Look at sticker under router.
What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
Are you wired or wireless connected to the router?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

What wireless modes are you using? Under Setup/Wireless/Manual.
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.
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.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partition and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

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.

Keep us posted on any results.
Maybe someone can review your router settings with you using teamviewer if your interested. Its safe and secure.

Well the changes you suggested **seem** to have improved things - I don't know how much of the residual slowness is due to my crappy ISP.

We'll see how it goes..


Thanks to everybody

Hope it keeps going well. Keep us posted. Might try a new ISP or ISP Modem as well. Good luck.
