Divide the bandwidth among two routers.
Divide the bandwidth among two routers.
Also, if you intended to divide the cost, the ISP might view it as reselling their product, which is against the law. You could claim it's a split, they might argue reselling, and you'd have to go to court to resolve it. Alternatively, if you're trying to be considerate and let your neighbor use it for free, do so discreetly. Avoid setting up equipment or creating extra subnets—anything else could be seen as intentional sharing. If anything goes wrong, those actions might serve as evidence of your intent. Ideally, if your neighbor accidentally gets your password, leave it untouched.
It’s simple to purchase a 16-port switch with 100 Mbps Ethernet and connect each neighbor via cable. Your ISP likely has terms stating your plan is for personal use only, and they might inspect traffic patterns—like many YouTube streams—to determine if it belongs to one household. If you’re accessing many sites simultaneously, it’s unlikely to be a single family using the service. There are drawbacks: you could face legal responsibility if neighbors misuse their accounts, such as using stolen cards or torrents. You might explore business accounts offered by ISPs, though these are usually pricier and come with restrictions.
They monitor your activity. How do you believe Comcast managed Bit Torrent or Netflix traffic? They employ packet sniffing techniques, revealing the data flowing through your network. The only effective way to prevent this is by using a VPN. Additionally, ISPs track usage patterns as well. Every ISP I’ve encountered enforces a data usage policy, warning users that exceeding limits may result in service termination—even with unlimited plans. I’ve heard Comcast and Verizon both impose roughly a 10 TB limit before you receive a stern notice from them. With Comcast, extra charges apply for the "Unlimited" plan. Another method of surveillance comes through DNS servers; that’s why I avoid using my ISP’s DNS services. ISPs also maintain access points to equipment they rent. There was a post where a Comcast employee admitted they can view devices connected to their gateways. That’s why I own my own modem and router. You’re also aware that much of this traffic is routed to the NSA, as seen with AT&T’s NSA equipment in their data centers. In short, you’re being watched. Adapt accordingly. Comcast ignores it all. Many rely on Business Accounts for unlimited data, which often come with static IPs and other perks. The trade-off? You usually pay more for slower speeds, especially compared to your residential customers. They clearly target residential users while offering better service to businesses.
Well... but here's the uglier side to that coin... and I KNOW you can find lots of cases of it online... is that the account that bandwidth is coming from is you. Whomever you are sharing it with (even though think they are top shelf and all that) decides to be searching for kiddy porn. Maybe not even getting, but searching. Your IP is tagged and the Feds come in and raid your house. "They won't find proof of anything, so what?" So your house gets tossed and damaged. Your name gets smeared all over the federal lists as a "potential" child molester and you spend a few weeks in jail while they forensically dig through your computer gear. You lost your job and even though you weren't guilty, a flag comes up on your record that you can't escape. Your skeevy neighbor/friend/customer gets off scott free. Happens man. Just sayin... You really don't want that kind of liability. People do weird shit for strange reasons even when they seem to be perfectly decent human beings. Smart people do dumb shit. Don't involve yourself. That's a tag you can't ever shake...even if you did nothing wrong.
