It doesn't really work like that. If she lives away with a crappy / slow connection, that would limit the maximum bandwidth she can receive and it's just crappy that would limit the quality she gets.
If she lives close enough and you have a long enough cable however...
Jokes aside if you want to share your home network with her to access files and directories you can do that. I would advise something like Hamachi for the first time. Easy to use, i belive it's still free.
There's a damn good chance that your ISP (or the NSA) keeps a log of all your traffic, but I don't know how plausible it is to request that from your ISP.
To watch in real time, I'd personally recommend WireShark. This is a pretty easy way to monitor all the traffic on your LAN in real-time.
If you're not planning on staring at your monitor to watch the traffic, you may consider something like Splunk Home Monitor. Splunk is a enterprise level security tool and is extremely useful. That Home Monitor version of Splunk looks like a neat tool, although I've never used it.
These options may be for a more slightly advanced user to use and configure, but going "incognito" only affects how the browser handles storage of the websites that are visited (cookies, cache, etc.). The traffic itself isn't really affected by this option (on a macro level).
I hope this answers your question. Feel free to PM me if you would like any further assistance.
That is just a router, not a modem.
If you wanted to bring your own modem, not knowing who your provider is or exactly what type of service you are on, I'd recommend something like: this
But you might want to just start with the router and having your ISP put their modem into bridge mode.
Depends on the ISP. A lot of the free streaming services (like PopcornTime) use torrents to stream their movies. Usually with torrents, they only say something if someone files a complaint about it. The only other way is if they block the entire Bittorrent protocol.
I would highly recommend using a VPN, especially with streaming. There's really no way for you to get caught if you use one. I personally use PIA (Private Internet Access). Pretty cheap and very reliable.
Use a VPN. Private Internet Access or Torguard. If you cant, atleast use a SOCKS5 proxy (Often free, but careful, this could do more harm than good if the proxy is a honeypot) If you need a (TEMPORARY!) fix, is free (Yes, I know free VPNs are looked down upon....) and does not log and allows torrents.
Uncap as in? Like get bandwidth without paying for it? Not very legal, could land you in trouble. If you really need a few extra megabits, maybe setup a high gain antenna and grab WiFi from around your area, and setup something like Speedify maybe? This can use a few slow links to make one fast one. If your ISP is throttling you, use a VPN which can get you much better speed. If you mean something else please explain
GTA online will have issues on a double NAT(cellular tethering), you'll have limited connectivity there and might get the occasional disconnect or two(my own experience). you could possibly use a vpn to bypass that network restriction. what i would do is get a travel router and bridge the mobile hotspot over to your main network.
on your travel router, set the netmask as the same as the main network, set the ip address to an unused one in your main network(ex: 192.168.1.2 for travel, 192.168.1.1 for main), and disable dhcp. connect the routers together via the lan ports, don't use the wan port on your travel router. then, if you want, in your main router's settings, set the default gateway to that of the travel router(ex: 192.168.1.2). then, devices will route internet connections through the mobile network by default, unless you change their gateway to that of the main router(which you can do in the device's network settings). in desktop operating systems, you can sometimes even specify multiple gateways. if you do that and set both gateways' network metrics(priority) to the same, you can then sometimes utilize both networks' speed(for example downloading a game through steam or using bittorrent)
or, before doing any of that, try to enable QoS in your router's settings.
