There's only one tiny spot in my dorm room where I can get the campus wifi network. Is there any way I can set up my MBP to act as a repeater so other devices in my room can have wifi access?
sharing your network connection would essentially do the same think as acting as a repeater. it would allow for a small boost in the signal to other computers.
No, he's trying to take an existing wireless signal, pick it up via the airport card in his laptop and then broadcast it. That's not possible.
HOWEVER, if he as an ethernet jack in his room, he can hook his laptop up via ethernet, go to sys prefs>sharing>internet and create an ad hoc network for his other devices that SHOULD work, depending on the school's network settings.
no that is not correct. he CAN share the network signal from his computer to other computers. in network settings there is a tab that allows for sharing, which will not extend the network, but will share it to other computers close by (only macs??)
It would be, like, trying to plug two ethernet cables into one port.
Your Airport thingy in your MacBook only can recieve OR send, not both at the same time. If you really want to use it as a wireless repeater, I suggest you buy a wireless card you can stick into your MacBook (some you can even directly plug into you USB port like a memory stick).
Dude, no. You can't both receive and broadcast using the same connection.
For instance, you can tether to a blackberry via Bluetooth, connect to the internet and share your connection to other computers via WiFi.
Or you could connect to the internet via WiFi and share it to other computers via ethernet.
But you CANNOT receive via WiFi and then "share" that WiFi connection. The sharing tab is sys prefs does NOT work like that.
Get it?
