Community Reviews

This refurbished Netgear Nighthawk cable modem is a DOCSIS 3.1 option aimed at high speed cable internet, but the thread focuses more on compatibility and value than on features. It can work well once activated, and one long term owner has had 18 months without issues. The main theme is that cable providers, especially Comcast and Xfinity, can be picky about modem support and upload speed tiers, so the right model matters. There are also concerns about refurbished units being returned for faults or old age, and the price feels high for older hardware.

  • Comcast/Xfinity customers who want to try a compatible DOCSIS 3.1 modem for better upload performance because cable providers push configuration/firmware and some modems only work for "mid-split upload" on specific models.

  • People who already have a working setup and just need a replacement cable modem because one commenter has used this exact type for 18 months with no issues.

  • Comcast/Xfinity customers who need guaranteed "advertised" speeds because community members report refurbished/third-party modems often get returned when they don't meet provider speed requirements (for example, upload limits on some models).

  • Buyers who are unsure why a refurbished modem would be returned because commenters point out that with no moving parts it can feel unclear what could break, and they've seen stock/checkout errors that add to the uncertainty.

  • People who want maximum reliability from a refurbished unit because reviews cited in the thread mention failure modes like dying after about a year, getting stuck rebooting, or not delivering signal.

Quote from Caleo View quoted comment :
You don't necessarily need the CODA56, there are some others you can choose from... but I think it's among the least expensive, and it works for me as indicated above so I'd say I'd recommend it. Can't comment on longevity though, as I've only had it for about a month so far.List is here under All modems -> "Compatible modems for enhanced speeds"https://www.xfinity.com/support/i...tomerowned
Yeah I have been all over this for the last month plus to no end. They tell me if I use their modem the speeds will be closer to advertised. Never get above 1k down and 200 up with the night hawk cm3000. Very annoying!

appreciate the link and info
