Ad hoc wireless mode: 802.11 B only.

Tx Rate: Auto.

There are no check on the following:

Please help me!!!

Kindly type in important selections to be made on the Wireless Connection Properties also.

The computer of my mom used to connect through Local Area Connection could this be one reason it won't connect wirelessly?

Some home devices can cause interference between your computer and networks that might be in range. For example, microwave ovens and some cordless phones use the 2.4 gigahertz (GHz) frequency, which is also used by 802.11b and 802.11g network hardware. Other cordless phones use the 5 GHz frequency, which is used by 802.11a network hardware.

There are two things you can try in this situation:

If any devices like these are near your computer, turn them off temporarily or move them farther away.
