How can I get a new IP address from Comcast with the Netgear C7000V cable modem? Yahoo will not allow me to login to email from any account
Yahoo for some reason would not allow me to log into any email account and received the message . “Something went wrong. We could not sign you in. Try again from a different device.” After spending a few days spending time clearing cache, attempting to log in from a different PC and performing many other PC tasks I figured out the reason I could not log into Yahoo email. For some reason Yahoo was keying on the cable modem IP address created and assigned by Comcast for not enabling me to log on.
The ipconfig/release then ipconfig/renew may not always work in getting a new IP address assigned. The C7000V cable modem software does not support changing the C7000V MAC address which would enable Comcast to issue a new IP address. However, I believe I have found a work around way to have Comcast issue a different IP address to the cable modem.
At the command prompt on your pc, issue the ipconfig/release command. Then from the Xfinity web site or Xfinity app on your phone issue a reset to the cable modem. After the cable modem has fully reset issue the ipconfig/renew command at the command prompt.
After receiving the new IP address I was able to log into my email accounts

The online manual at http://www.downloads.netgear.com/files/GDC/C7000v2/C7000v2_UM_EN.pdf has instructions for this on page 29, step 9: "For the Router MAC Address setting, select one of the following radio buttons".
