Reviews around advertise (3.80 of 5)

  • The weak physical connection to the coaxial is something I can deal with, but the fact that it gets nowhere close to the advertised download speed for the specific provider is just blatant false advertising
  • After getting it set up with COX it worked as advertised, things per specs, then the next morning I went from 110Mbs to 10Mbs, lots of chat with COX, they too had slow speeds
  • So overall the product works as advertise, its just dealing with the IP/cable company the reason it isn't given 5 stars.
  • and he could not get this modem to work with their system, despite stating -- as advertised -- it works with their service.
  • I'm giving this just 1 star based on false advertising

mac numb

Reviews around mac numb (1.49 of 5)

  • I told them that the label has a "CM MAC" number and I asked them if that was what they were looking for.
  • I called and gave them the mac number and two days later had a tech visit house as he had to run new cable from the street
  • After a wild goose chase of scouting around for some mysterious "MAC" number, I was unable to find any others they were looking for.
  • Works as
  • They come back on, only to then apologize and to tell me that the router label's "MC MAC" number was in fact the same as a "MAC" number that they were asking for to begin with.

ip

Reviews around ip (1.00 of 5)

  • (-/+ 5 minutes, the modem would loose its IP and my router behind it would report, "ISP DNS/DHCP configuration error".I travel and also remote office ( even prior to COVID-19)
  • Losing the IP, reboot....and repeat
  • I get about 650Mbps down which is my rated speed from Comcast after upgrading to this from an older one that maxed out around 250.During activation, make sure you connect directly to it from your pc and set your pc to dhcp if you are using a static IP.
