I have picked up the Netgear D7000 router from Maplins to replace the BT HH5 Type B which keeps restarting itself within each week or two and I'm wondering what is the best way to swap out the router without it affecting my line DLM etc, should I just unplug the HH5 power from the wall and connect the Netgear router?
One disconnect will not cause DLM to affect your line. Just unplug it and fit the new router.
TGo to hub manager then you should find that you can disconnect from inside hub manager. You can then unplug rj11 and power and install the netgear
more controlled disconnect than just pulling cable out
De-power the Hub then disconnect from line. Power up the Netgear and make all connections except connecting to line. Wait at least 30 minutes and then connect Netgear to line and complete configuration if necessary.
Yes disconnect from the internet from within hub manager then just unplug rj11 and switch off hub
then just connect up the netgear
