yes go into the routers config page and i think usually on the first page you should see what mac addresses are connected. if you only have one pc attached but it shows two macs then someone else if connected, just block that mac address. it would also help to know what router you have.
Most practical and cross-platform friendly would be MAC address logging, but that only shows active list. I have seen a few Linksys models that keep a log, but I think the logging is off or on a very low expire level by default.
I would also assume if the suspicion is there that someone is connected, your router is un-encrypted.
If that's the case, I suggest tightening your encryption to the highest level your router and wifi devices will support.
incorrect. If you leave the keys in your car or a loaded gun on the front porch and someone uses them to kill another person you will be tried for murder. The legal term is "contributory negligence". The legal precedents do exist. It also applies to products and companies. Do not beleive? Ask the tobacco industry why it is paying hundreds of billions in fines, penalties etc. in spite of a warning on the side of the package.
You never shop over the internet and use a crdit card? You never bank or use a stock account? No site you access ever requires a SS number as a user ID? You don't pay bills online or renew your car registration?
Think that if indited you will never be convicted. You are convicted by the very indictment process. It will cost you 10's of thousands to beat the charge (if you can). There will be records spread all over the web, newspapers and governemnt saying you were indicted. Some of the records can be expunged (at additional cost to you) but not all. These records can be used to deny you employment or to terminate your employment. You can agfain get the action reversed at large expense to yourself.
It happened to my brother. Took 5 years to get everything dropped and $30k. There is no compensation for false criminal accusation by the police, DA, governemnt agencies, etc and only recourse is civil suit against individuals which will cost another $30-50k to prosecute and can yield no money even if you win. Ant attempt to recover losses requires proving "malice" on the part of your accuser. Very difficult to do (see the movie).
Keep your doors locked, your tool shed locked, your guns with trigger locks and your internet encrypted with the best WPA, hidden ID and anything else you can find.
I'm not incorrect, the INTERNET is free, your car or a license to drive is not free, it's not illegal to provide free INTERNET, it's done all the time all over the country, it's done in coffee shops, it's done in municipalities
water is free too
The legal precedents do exist. It also applies to products and companies. Do not believe? Ask the tobacco industry why it is paying hundreds of billions in fines, penalties etc. in spite of a warning on the side of the package.
the legal precedents don't exist, a prosecution would be novel and it would fail
tobacco companies lied to their customers, that's why they are liable, that's the only reason they were liable
