I was using hub 3 in modem mode when I went to add a access point to my network, put while doing this, my internet dropped out. Upon checking the hub 3 the light was red. I rang support. The support agent tested the line and rebooted the hub 3. But it still red lighted. The support person told me that it looks like my hub needs replacing. After waiting for a call back for an engineer to come out. I thought I’d try a few things
i reset the router and the connection came back and solid green light.
I then tried to put the hub back into modem mode. But again my internet went down and red light appeared.
So again I reset the hub 3 and connection came back.
I just can’t see why turning router into modem mode breaks the router.
now a week later still no one has rang me back.
