Mobile routers are expensive because they are designed to provide reliable and high-speed internet connectivity on the go. They are equipped with advanced technology such as 5G capability, multiple antennas, and powerful processors to ensure seamless connectivity. Additionally, mobile routers often have built-in battery packs for portability, which adds to the cost. The demand for mobile routers is also relatively high, which can drive up the price due to market forces. **

GL.iNet routers are generally considered secure due to their use of open-source firmware and regular security updates. They also offer features such as VPN support, firewall, and ad blocking to enhance security. However, like any device, the security of GL.iNet routers also depends on how they are configured and used by the user. It is important for users to regularly update the firmware, use strong passwords, and follow best security practices to ensure the security of their GL.iNet router. **

Some good 5G routers currently available in the market are the Netgear Nighthawk M5 Mobile Router, Huawei 5G CPE Pro 2, ZTE MC801A 5G Indoor WiFi Router, TP-Link Archer MR600 5G Router, and the Inseego 5G MiFi M2000. These routers offer fast and reliable 5G connectivity, advanced features, and good coverage for multiple devices. It is important to consider factors such as network compatibility, speed, range, and additional features when choosing a 5G router. **

Third-party routers are networking devices that are not manufactured by the internet service provider (ISP) and are instead purchased separately by the user. These routers can be used to create a wireless network in the home or office and provide access to the internet. Third-party routers offer more customization options and advanced features compared to the routers provided by ISPs. Users can choose a router that best fits their needs in terms of speed, range, and security. **

Routers can vary in age depending on the model and usage. Generally, routers can last anywhere from 5 to 10 years before they start to become outdated or experience hardware issues. However, with regular maintenance and updates, some routers can continue to function effectively for longer periods of time. It's important to keep an eye on the performance of your router and consider upgrading to a newer model if you start experiencing connectivity issues or slower internet speeds. **

WLAN routers can be considered "bad" for a few reasons. Firstly, they can be susceptible to security vulnerabilities if not properly configured, potentially leading to unauthorized access to the network. Additionally, WLAN routers can experience interference from other electronic devices, leading to slower or unreliable internet connections. Furthermore, some WLAN routers may have limited range, making it difficult to maintain a strong signal throughout a larger space. Overall, while WLAN routers are convenient for wireless internet access, they can present challenges in terms of security, reliability, and performance. **

Yes, there are routers available that do not have external antenna connections. These routers typically have internal antennas that are built-in to the device. While routers with external antenna connections offer the flexibility to upgrade or replace antennas for better signal strength and coverage, routers without antenna connections are often more compact and aesthetically pleasing for users who prefer a sleeker design. **

Routers that have a SIM card slot are typically referred to as 4G LTE routers or mobile hotspots. These routers allow users to insert a SIM card from a mobile network provider to access the internet via cellular data. They are commonly used in situations where a wired internet connection is not available or as a backup for unreliable connections. Some routers also have the capability to use a SIM card for failover in case the primary internet connection goes down. **
