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?
Swap out router without affecting the line
- Thread starter Lither
- Start date
Straight swap with minimum down time and I doubt anything will be affected at all.
I would first plug Netgear D7000 into your computer and check to see what firmware version it is running on. If it is an old one go to https://www.netgear.com/support/product/D7000.aspx#download this Netgear support site to download the new firmware then once that is updated.
Unplug the HH5 from the wall and leave it for half an hour to an Hour then connect the Netgear D7000 router. This length of time is important, otherwise DLM will think there is a line fault.

DLM really isn’t that sensitive.
You can swap a router without DLM thinking the line is unstable. Power it down while it's still attached to the line, then swap the cables over and power your new one up.
Maybe do the firmware updates on the new router and set things up in advance so all the reboots are out of the way.

The proper way to have DLM ignore any DC on your line, whether you are changing modems, routers what have you. Is to:
1. Power down the Modem/Router. Ideally by logging off the connection so DLM gets that signal first.
2. Then unplug the phone line to your Modem/Router.
3. Wait 30 minutes.
4. During the wait, set up your new device by plugging everything in except for the phone line, and power.
5. After 30 minutes is up, put the phone line in, and power up the device.
DLM will ignore that power outage period and won't count it against you. The actual wait time is 15 minutes as DLM takes snapshots at those intervals, however, if you powered off exactly at 1s before and powered it back on 1s just as it takes the next one, DLM will see it as a fault issue and count it against you in future DLM changes. So to be safe, just take a 30 minute break so there's a clear "block" of time that DLM see's that the line is out. Therefore it won't count those against you as it's too long for a reconnect attempt and instead sees it as a full on line issue that an engineer is either going to be looking over or already is.

I've been reading that BT DLM doesn't record the last gasp properly, or doesn't count it, just the time out periods, and hence the method I typed out is utilised by people to prevent DLM error count from working against you. Could have changed I guess, but I'll be honest, I'd rather take 30 minutes to make sure DLM won't count it against me as this works against the system in place for DLM, or I can chance it and see how it goes. And as I've done the manual switch off before and all it did was count it against me, 30 minutes it is for me forever more.

Just to add, this method is best if your line has frequent disconnects if the line is unstable originally. Since it's just one more DC that DLM sees. Hence the need for the 30 minute window. If your line is super stable and clear (free from any noise), then a one time switch is perfectly fine that is done over a few seconds or minutes. As there won't be more DC's along the way. However, as OP was talking about moving from a Biweekly Reset on a HH5b, I'd suggest taking the 30 min approach just to reduce the amount of disconnections that DLM sees.
