"I am unable to install/uninstall software programs." Why? What happens when you try, and what error messages do you see?
"I can't bring up "connect to a network". Without knowing more I am not sure what help can be given, eg what type of internet connection, broadband, cable, wireless, router?
Don't forget those words in red;
Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.
Mark
1) I am unable to install/uninstall software programs.
2) I can't bring up "connect to a network". I can't see the network I connect to. Some locations I go to require that I see the network so that I can click connect. By my not being able to see it then I can't connect.
