I often use my laptop to open a wifi hotspot for others to surf the Internet. Are there any side effects on the computer?

It affects the network speed and does no harm to the computer itself.

Set up a hotspot network by the following steps:

1. Open the start menu-Settings-Network and Internet in the control panel. Find the network and the * * * enjoyment center. Manage the wireless network in the upper left corner and turn it on. Then enter and select Add to add a wireless network. Select Create Ad Hoc Network.

2. In this Manually Connect to a Wireless Network panel, click Next. Fill in the network name,-Select WEP-As the security type-Set the security key-"Save this network".

3. Return to the Manage Wireless Networks panel, and there is an option to change the adapter settings. Enter, right-click Local Area Connection and select Properties. In * * * Enjoyment, select the wireless network connection option, then check "Allow other network users to control or prohibit * * * Enjoyment of Internet connection", and then click OK to create a hotspot network.
