Also, check whether the PCI card providers have dedicated 24/7 customer support. This will help you fix any issues you might face during the process.

Wi-Fi Security

Buy a product that has the best combination of security settings. Set up a password for your network, and also look for WEP encryptions. All this will safeguard your wireless connection from unauthorized access and hackers.
