Question about safely sharing broadband

in Techie Stuff
I would appreciate a knowledgeable answer to this question...
My neighbour has approached me with a proposal. He is building a new house adjacent to my garage for his son. I currently have broadband on the old copper wire, but recently BT have made fibre available. He is offering to pay the difference for me to upgrade to fibre, in return for me setting up a piggyback router in my garage where the son can access it from the new house, so that they don't have to have a landline and can use mobile WiFi. (My neighbour's own house is further away from both my house and the new house, out of reach of WiFi.) Now, I know how to set up the router, and I know that it should be technically possible. But if I do this, and set up a password on the additional router for him to use, what is the risk (not that I mistrust my neighbour or his son) of some techie friend hacking into my own router and accessing my data (bank details, for example)?
Thanks in advance!

You'll probably find this is against the terms of just about evey domestic broadband provider would be the first thing, and when neighbour's son lets his friends use your connection and they start downloading horse !!!!!! or uploading ISIS videos, the police will be knocking on your door.
Think about that first, and if you still want to go ahead, learn about VLANs, internal firewalls and network segmentation.Proud member of the wokerati, though I don't eat tofu.Home is where my books are.Solar PV 5.2kWp system, SE facing, >1% shading, installed March 2019.Mortgage free July 20230 -
while they are way to hack in. providing you do not have shared folders, blocked 'everyone' groups/users and all your local accounts are passworded, you are fairly safe.
You could also set up firewall on your PCs. and disable his ip's from coming in to your system.

Think dd-wrt software supports multiple ssn and vlans on select routers?
############
I would enable qos on the router as his downloads or connections could eat your bandwidth too, and for an extra 30-40 a year would put a vpn on the router to avoid horse !!!!!! problems.
if you start start downloading horse !!!!!! or uploading ISIS videos, the police will be knocking on your door, you have a viable defence that you modem is shared.
############
Taking up the cash difference for no gain, more electricity use, knocks on the door to get a router rebooted, is possible not worth it for you? However a greater incentive may swing it to your benefit.
When my neighbours moved in I let them use my wifi till they got connected.
############
For about £30 you can buy on ebay a Draytek 2820 or 2830. These allow 4 multiple wifi access with separate ssid and p/words, qos, and you can isolate the networks, but they do not support openvpn. Check them out before you buy.0 -

Sounds right, but certain companies will not extend their infrastructure. The house may be bound by the wrong area, or the exchange is full etc.

yes how stupid of me to think that when building a house you can get running water, power other various building regulations but don't be so stupid to think you can get connected to the internet and not have to piggy back off another house.

Sorry john, just re-read the OT and I read as far as "is building" , missed the point aboutHe is offering to pay the difference for me to upgrade to fibre, in return for me setting up a piggyback router in my garage where the son can access it from the new house, so that they don't have to have a landline and can use mobile WiF

The risk is small - but it is there.
It is completely dependent on how skilled the teenager and/or his friends are ..
Wort case scenario for you is that teen/friend is a "script kiddie" with an interest in Kali linux.
Would take him mere minutes to poison your ARP table, start pretending to be your gateway, strip ssl and then start watching ALL of your internet traffic ..
Dont bother0
