I possess nine gadgets linked to my 16-port hub, featuring my laptop for testing purposes. The hub then links straight to my router approximately two feet away. The issue is that the hub becomes unresponsive or forces all connected devices to lose network access. This is confirmed by regularly sending pings from my laptop through the hub while connected, and seeing the typical yellow warning icon appear. When this occurs, I can restart the hub and it resumes functioning immediately, though within one to two minutes it restarts again. To diagnose, I isolated each device individually on the hub to pinpoint the faulty unit or cable. Surprisingly, six out of nine devices triggered the hub failure or shutdown. Only three operate smoothly: my test laptop and two credit card terminals. This suggests the problem likely stems from a defective hub, as those working directly on the router remain unaffected. It’s unclear whether six faulty items could coexist without causing failure, yet they function normally when connected to the router. The likelihood of all six devices or cables being defective remains uncertain, especially since they perform well in isolation. I suspect a faulty hub is responsible, so I replaced it with another brand, and similarly switched the router, yet the issue persisted. This leaves me puzzled and seeking advice.
The six devices involved appear to be part of a loop or multicast/broadcast spam scenario.
Did you test Wireshark to observe the behavior when connecting one of the six affected devices? Could it be related to cables, with the router supporting 100MB and the switch handling 1GB? More details would be useful.
It seems the router could halt the broadcast storm or simply discard the packets that cause it, whereas the switch lacks the capability to identify and block them. Using models for routers and switches would also be beneficial.
I agree with the concern about the models involved. To assess the switch's specifications, I’ll also check Wireshark to observe broadcast traffic when a device is connected. Regarding IP allocation, it’s worth investigating if any unusual conflicts exist between the router and switch.
I plan to use Wireshark later today. I'm not sure about the impact if the router is 100MB and the switch is 1GB. Wouldn't the switch handle it by adjusting or transferring at 100MB for compatibility?
I’ll have it ready by the end of the day. I recall the updated switch is a Linsksy with 16 ports, while the previous router was a TP-Link. Both were purchased at Walmart.
