HI there, thank you for reaching out

Yes Frogfoot uses PPPoE on our Network1. Does FF use PPPOE (ala OpenServe) or DHCP (ala Vuma).
Frogfoot does have Ubiquity ONT's in some areas, but normally has a Sticker with an FRG number on it, however we can place an "incomplete install" order so that FF can do a site survey to make sure all is in order.2. There is a fibre connection coming into the place but it was not plugged into anything. Found one of those small Uniquiti Fibre ONTs and I’ve plugged it in, but no router plugged into that. Found 2, not sure which it will be, 1 is a Tenda and the other is a Mi (Xiaomi). There was a TPLINK XE500 or some such TR069 capable router (I know Afrihost loves that). This relates to Q1. If the net is supposed to cancel only at the end of August and I can use it until then, how do I get somebody from FF to come out and make sure it’s all kosher still.
I would typically recommend a week before the time, perhaps a week/half if there is going to be a site survey needed.3. When do I place my new order for the new place with CI so that I am up and going as early in September as possible. Wife works from home so quickest resolution is important for me.
We can always request a early line release, but that would depend on Frogfoot unfortuantely. We would need your Proof of Address to show that you are the new tenant in the residence, which can speed up the process.. If I want to get CI in quicker, s there a way I can settle the full August month for the previous Tenant with AH and/or FF so that they release sooner?
Frogfoot would possibly be able to locate it with the address in question, or they would allocate a new one when the order is placed.5. The old tenant is not technically inclined so how do I get the circuit number or whatever it is FF uses.
