C7100V cable modem/router will not recognize external USB device
Modem/Router doesn't recognize external HD. This seems to be an issue with this model. Previous solutions (replace until you get one that works) and power cycle (reset) and hope that works. Any ot...
What format are they in?
The router supports the following file system types for full read/write access:
- FAT16, FAT32
- NTFS
- NTFS with compression format enabled
- Ext2, Ext3, Ext4
- XFS
- HFS
- HFS+
Well, that could be my problem. The two HD's I tried are Mac OS Extended (Journaled). The thumbdrive I tried (32 Gb) to make sure it wasn't a HD size issue is APFS. I will try format a thumb drive with FAT16 or FAT32 and give it a try.
Ya, Modems don't respond to Apple formatting. NTFS would be best and most compatible between the modem and Apple if you are using Apple PC platforms.
I will have to give that a try. I found an old thumb drive that was FAT32. I tried it and it still doesn't recognize it. Maybe I need to do a reset with the thumb drive installed? Other option would be to format the thumb drive with NTFS. I should be able to do that on my work computer which runs Win 10.
BTW, I just upgraded our old home network from an Aris 722 cable modem + Apple Airport Extreme wireless router which still works fine but compromises speed to the Netgear C7100V modem/router combo. We still have and need for a landline so we needed a cable modem that had a landline port. Rather than purchase a modem and router I decided to get the combo. I also really wanted USB to run my back-up HD. That is how we unded up in this space.
I'm willing to reformat the HD if necessay. I just want to make sure it's working before I go that route. I was hoping the thumb drive formated with FAT32 would immediately get recognized. I will have to wait until early tomorrow morning to reset the modem.
