The Dell Inspiron 1150 is a laptop computer based around an Intel Pentium 4 or Celeron processor. The Inspiron 1150 has an internal mini PCI slot that supports a wireless card. However, depending on the wireless card that you selected when ordering the computer, your Inspiron 1150 may have a card that only supports up to 802.11b wireless networking, which is significantly slower than the 802.11g standard. The 802.11g standard can raise the maximum speed of wireless data transfers on the Inspiron 1150 to 54 megabits per second, and you can upgrade the card yourself with off-the-shelf parts.

Shut the Inspiron 1150 off. Remove the battery pack and place the computer on a flat work surface with the bottom facing up.
Unscrew the Phillips-head screw holding the large rectangle-shaped cover to the underside of the Inspiron 1150. With the screw loosened completely, place your fingernail in the seam between the cover and the casing of the Inspiron 1150 and lift the cover to reveal the compartment underneath. The card with two small wires connected is the Inspiron 1150 wireless card.
Make a note of which cable is connected to the "MAIN" antenna post on the Inspiron 1150 wireless card and which is connected to the "AUX" antenna post. Remove the two antenna cables and move them out of the way.
Pull the two metal arms apart that hold the Inspiron 1150 wireless card in place. When the card rises out of the slot, remove it and place it in an anti-static bag.
Hold the top part of the new wireless card over the metal arms. Tilt the bottom of the card downward and insert it into the empty slot. Press the top of the wireless card down until the arms snap around it.
Connect the two antenna cables to the posts on the wireless card and move any slack out of the way so that the cover does not crush the cables when you reinstall it.
Lower the cover onto the casing of the Inspiron 1150 and screw it down.
