How we can use the wireless connection on PSP’s, laptops, etc, using the same username and password

You can use the internet connection username and passwords on multiple PC’s and share the Internet and the cost between the two, but there might be a catch. You will have to find out from your Internet service provider about the legal issues here and also the way it works. Firstly, check if you and your neighbor can connect at the same time and use the Internet. If you connect, and then your neighbor connects using the same username and password, you may get logged off . Both might not work at the same time. Check with your ISP for details. Secondly, check with your ISP whether they are tracking MAC IDs for Internet connection security. This means that only the registered (one or multiple) computers’ MAC ID will be allowed to use the Internet connection with your username and password. Check with your ISP if you can have multiple MAC IDs logging in using the same username and password. Also, check if there is a limit on how many machines can login at the same time. If the above criteria are allowed and you can use multiple machines, then the speed will be shared. For example, if your ISP is providing you a 1 Mb/s connection and two computers are using it at the same time, then you will be sharing this 1 Mb/s between both machines. Both the machines will not get 1 Mb/s each. If you want to be safer and manage without the above issues and hassles, I would recommend that you make use of a wireless router and share the Internet connection between other computers and your neighbor from your router. Your ISP will not be involved in this matter. You can use as many computers to share the Internet connection as you wish. One more issue that can be a cause of issues between you and your neighbor is the sharing of cost with the ratio of the usage/bandwidth shared. What I mean here is that if you have a 1 Mb/s connection and you are only browsing and accessing email, while your neighbor is downloading movies, software and music, he will be drawing a larger amount of bandwidth than you. This could slow down your internet connection id he is hogging up almost all the bandwidth. If your neighbor is involved in any illegal Internet activity, such as downloading illegal content such as pirated music and movies, the law will trace the IP address to your Internet connection and you will be held responsible. Do this at your own risk. I would recommend that you let him opt for his own Internet connection.
 
Use a wireless router to share the connection between PCs where a physical wire is not possible.
