1 edit | [Speed] Finally: A True Comcast Network SpeedTestIt takes a little work to find, but it is definitely the best speed test (IMHO of course) available to Comcast users. You need to find one of the 'cdn' server IP's that serve your area. For a little background, the cdn servers serve the 'downloadable_install_wizard.exe' file that is used when signing up and/or changing modem.
A somewhat buggy procedure to find it:
1. ping -a your dhcp server and get the reverse DNS name:
In Central Jersey/Philly that would be:
phil2-pdhcp.inflow.pa.bo.comcast.net
2. If there is a number by the first part of the address (phil2 in this case), remove it, and replace pdhcp with cdn01, cdn02, cdn03, or cdn04 (I don't know if all areas have 4 cdns; some may have more or less)
3. You should now have phil-cdn01.inflow.pa.bo.comcast.net, or whatever your local cdn is.
4. Open Internet Explorer and go to
http://yourlocalcdn/downloadable_install_wizard.exe
This is a 36MB file and should be a decent speedtest.
For those of us in my area, you can use
http://phil-cdn01.inflow.pa.bo.comcast.net/downloadable_install_wizard.exe
without following the above steps.
Please keep in mind that the above method is by no means fool proof and just a suggestion on how to get a true speed reading on Comcast. |

Re: [Speed] Finally: A True Comcast Network SpeedTest I feel kinda dumb but how do I find out my dhcp server...
Ive got a router and it shows nothing in dhcp, I know via ipconfig /all on my pc it shows my router as the dchp server, so would the dhcp server on my router be the default gateway, if so I get...
cdnt01-a-rtr.******01.**.comcast.net

I couldn't find anything for my ex-attbi area in Napa, CA but »phil-cdn01.inflow.pa.bo.comcast.···zard.exe still maxes out my 4Mb connection. I'm on the 67.xxx ip and a reverse dns of my dhcp server only shows c-67-xxx-xxx-xxx.hsd1.ca.comcast.net. |

Re: [Speed] Finally: A True Comcast Network SpeedTest Unfortunately, most routers do not tell you what the ISP's dhcp server address is. You will have to temporarily remove the router. |

I get a connection refused from my dhcp server. Speed still not what it should be. go comcast! |
