Help
Could some one write out the Steps to help me and others set up their 825's routers for speed. A Step by Step Guide would be Great.
I currently have a DIR-825 rev B running 2.07 Firmware, I have downloaded the 2.09 but have not installed it yet.
Any help would be greatly appreciated.

Internet Service Provider and Modem Configurations
- What ISP Service do you have? Cable or DSL?
- What ISP Modem Mfr. and model # do you have?
- Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
- What ISP Modem service link speeds UP and Down do you have?
- Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
- 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.
- If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://computer.howstuffworks.com/nat.htm). 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. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
This is a good router. Solid and works great. I have mine to my buddy down the road. He's still using it.

Thank you for your welcome and your information.
1. I am located in Colorado Springs, Colorado in the Foothills of the Rocky Mountains, about 60 miles south of Denver.
2. I to think it is a good modem, but I do not know why it slowed down so much lately.
3. a. Cable
b. Xfinity XB3 Modem ( http://www.cisco.com/web/consumer/support/modem_DPC3939.html ).
c. Dynamic ( I think )
d. 105mps upload / 25mps download
e. Cable Replaced with Cat6
f. MTU 1500
g. Not using DSL
h. The Modem is Bridged
I have replaced all of my Cat5 and Cat5e cables in my network with Cat6.I am going to buy a new RG-6 cable to replace the one between the Modem and the wall outlet.
??? - Should this Cable be Shielded or UnShielded ?
In addition to my D-Link Dir-825 Router I have a D-Link GO-SW-8G Switch for additional Ports ( This is plugged into the D-Link Router which is plugged into the Xfinity/Cisco Modem. The Cable coming into the House ( by Xfinity ) and splits into two lines one for my Network and one for Cable TV.
I will do the firmware update in the next day or two.
Thanks for your help and if you can answer the question about the RG-6 cable I would really appreciate it.

Since your uplink is high, try disabling Traffic Shaping...

Any status on this? ???
