Network connectivity issues refer to problems that prevent devices from connecting to the internet or communicating with each other. These issues can arise from various factors, including faulty hardware, software glitches, or problems with the internet service provider (ISP). Common symptoms include slow internet speeds, dropped connections, or the inability to access certain websites. Troubleshooting network connectivity issues often involves checking cables, restarting devices, or resetting the router. In some cases, users may need to contact their ISP for assistance. Identifying the root cause is essential for restoring a stable connection and ensuring smooth online experiences.
