USB-based wireless modem adapters are usually offered because all modern laptops have USB connectors.
Wireless modems are commonly used by laptops to connect to third party "hot spots" set up by Internet service providers (ISPs) in various places. What distinguishes wireless modems from the standard internal wireless network adapters found in laptops is that wireless modems connect to wireless cellular networks, rather than to terrestrial cable-based networks. This can cause unique connection problems that have to be addressed in a different manner than those of a typical wireless network.
Instructions
1. Move the laptop somewhere where a cell phone signal would be strongest. Since wireless laptop modems use cellular networks, they are subject to the vagaries of cellular network reception. Sometimes, ISPs use wireless repeaters in areas such as hotels and airports to strengthen these signals.
2. Make sure there is no interference from other cell phones, microwaves, cordless phones, wireless routers, etc., by changing the channel your modem operates on from the default, which is usually Channel 2, 3 or 11.
3. Insert a compatible PCMCIA wireless modem card, rather than a USB wireless modem. Just as with a cell phone, a bigger antenna can provide a better signal. With cellular Internet, consider upgrading to a 4G data plan, which is much faster than the standard 3G technology.
