How should you troubleshoot access problems with specific websites and Google services through a router?

First, confirm which device the phone and tablet are actually connected to, then compare connections “through the router” and “without the additional router.” In the reported case, the company website and Google services were inaccessible through the Chunghwa Telecom equipment but worked over a phone hotspot. This is a troubleshooting clue, but it does not establish that the router is faulty, nor does access to other websites rule out a problem with this connection setup. The available discussion suggests a testing sequence but does not establish the cause of this case.

First, clarify each device’s role and the scope of the problem

Whether the “Chunghwa Telecom router” is a modem with built-in Wi-Fi or a separate router connected behind the modem affects how testing should be done. Replies in the supplied material also asked about the device model, whether it was actually a network switch, and which device established the internet connection. Do not apply settings before confirming these details.

• List the models of the modem, any additional router or mesh equipment, and the order in which they are connected.
• Confirm whether the phone and tablet connect to the same device and whether both experience the same problem.
• Break “all Google services” down into the services actually tested. Record the error screens for the company website and each service, distinguishing timeouts, certificate warnings, and other messages.

Compare with a single-device direct connection to narrow down the problem

If there is an additional router, several replies suggested bypassing it first and testing with a single device connected to the modem. If the same website fails through the router but works with a direct connection, there is a more concrete reason to investigate the router’s settings. Another respondent had encountered this difference with LINE and eventually traced it to router settings, but that was not a diagnosis of this case.

Another suggestion was to connect a computer directly to the modem and test using a PPPoE connection if restarting the modem and router did not help. First, confirm whether the connection setup at the location supports this procedure. A working phone hotspot is not a substitute for a direct-connection test. If the problem persists after bypassing the router, ask the provider to investigate further.

If the direct connection works, check routing settings and filtering features

Views on routers differed in the supplied material: some said ordinary routers rarely interfere with website access, while others reported that security features had blocked websites and that disabling those features restored access. Check the actual settings rather than assuming that all routers either do or do not block websites.

• Check whether website filtering or security protection is enabled. The ASUS router example is only a lead for investigation and cannot be directly applied to Chunghwa Telecom equipment.
• Confirm the connection-establishment, DHCP, and NAT settings on both the modem and router. One comment suggested bridge mode to eliminate double NAT, but in a separate online postal service case, switching between AP and router modes did not help. Changing modes is not guaranteed to resolve the problem.

When requesting repairs, provide comparison results rather than simply saying “the internet does not work”

Compile the device models, affected services, and differences between hotspot and direct-connection results, and ask the technician to reproduce the issue using their own equipment. In the reported case, the provider’s staff responded by pointing out that other websites worked, but the material contains no follow-up testing sufficient to establish responsibility. Another person said a similar problem was resolved after a technician updated the modem’s internal software. This is something to ask about when requesting service, not evidence that this case necessarily involves a firmware problem.
