Firmware Update on CM400 Docsis 3.0 cable modem

According to the website, I have to contact my ISP to upgrade my firmware on my modem, but my ISP says that the manufacture sends out updates to them and it will eventually be updated.  My only issue is that Netgear's website shows that I should be on firmware 01.01.13 and I am currently on 01.01.08.  Is there a way to get my firmware updated?  I am having random connectivity issues and I am trying to troubleshoot both my cable modem and wireless router.  Two separate issues seem to happening.  I have wireless access but no internet, and after a reboot of the cable modem everything is fine.  Other issue is wireless drops and reconnects.  Everytime I have to reboot the cable modem.  Any answers would be appreciated!

    Hello Jackler

     

    You will have to contact the ISP again and ask for there L3 or higher up tech support as they will be able to help with those type of issues.
