Why does internet work on one device but not another?

Troubleshooting WiFi Connectivity: Why One Device Works While Another Doesn’t

WiFi connectivity issues can be frustrating, leaving you wondering why your laptop flawlessly connects to the network while your tablet struggles. The answer often lies in a combination of hardware and software factors, specifically concerning the nuances of WiFi standards and device compatibility.

The seemingly seamless connection of one device can mask underlying compatibility problems that hinder another. A crucial factor is the different WiFi standards supported. Modern routers often support multiple standards, like 802.11a/b/g/n/ac/ax (and beyond). While your laptop might flawlessly utilize the latest ax standard, your older tablet might only support the older g or n standards. If the router is broadcasting on a frequency your device doesn’t support, a connection simply won’t happen. This explains why a newer device might connect flawlessly to a network while an older one fails, despite both being in the same physical space.

Beyond the specific WiFi standards, the crucial role of drivers cannot be overstated. Drivers are software components that act as intermediaries between your device’s hardware (like the WiFi card) and the operating system. Discrepancies in these drivers can lead to connectivity problems. If the drivers on your tablet are not up-to-date, or if they’re incompatible with your specific router, a connection might be impossible. Similarly, firmware updates on the router itself can impact compatibility with various devices. A recently updated router might not be compatible with the drivers on an older device, or vice versa.

Another contributing factor is the device’s hardware itself. The WiFi chip within a device might have limitations regarding frequency or signal strength. If the signal from your router is weak or isn’t reaching the device, even if it’s theoretically compatible, problems will arise.

Furthermore, network settings on the device itself can play a role. Incorrectly configured security protocols or channel selection on the device can also hinder a connection. In cases where you have multiple WiFi networks available, automatic connection can be influenced by the priority given by the device. This becomes especially problematic if the network your device prioritizes is not the strongest or most reliable.

In essence, WiFi connectivity issues are often a complex interplay of hardware and software limitations. While a simple restart or router reset may resolve some problems, deeper issues might require checking for updates, driver compatibility, and verifying the support for particular WiFi standards on both the router and the device in question. If the problem persists, consulting a technician or checking online forums specific to your device and router models may provide valuable insights into troubleshooting the issue.
