External Harddrive to router problems

Hey team.

Loving infuse6 and has been working well but…

Just upgraded my external hard drive to 4TB it’s got just over 3TB of stuff on it but now when I plug into router it doesn’t pick up the hard drive (it used to) and it also seems to also down the internet (to the point where internet stops lol)

I have set this up before and it was working fine using the same new 4TB hard drive (but with less stuff on it) but now it has more on it it doesn’t seem to load anymore?

Any advice recommendations on this?

Check router message boards. Some routers have weird USB limitations for external drives.
