How can I improve a wifi signal/connection?Note: it's for outside use (school's wifi).
Get a simple wifi antenna, my computer came with one. Works nice.
The signal strength relies mostly on the router and settings and you can't do much about it unless you're the admin, as far as I know. If you want their signal range to reach farther, ask them to install a repeater in one of the outermost indoor areas.I'm not very knowledgeable with networking though so you would probably be better off talking to your IT guy here.
