Troubleshooting an Unresponsive Unmanaged Switch

    Switch
AI Thread Summary
The discussion centers around troubleshooting an unmanaged Cisco Linksys switch that is failing to allow a computer to retrieve an IP address via DHCP. The switch appears to be non-functional, as the computer works fine when connected directly to the main router. Unmanaged switches do not have DHCP capabilities and should be connected to a router for network access. Users suggest that since the switch cannot be reset and all ports have been tested without success, it is likely dead. Recommendations include replacing the switch if power cycling and port changes do not resolve the issue.

I have tried to reset my unmanaged switch (Cisco Linksys) by recycling its power several times but everything becomes the same. My computer can't retrieve the IP address delivered from it that is set up with DHCP mode.
If I connect my computer to the main router (the one that is connected to the Internet) then everything works fine (my computer is network-able). I guess my switch is being dead or likely already. :DD

Several comments:
  • In a computer network, an unmanaged switch is totally invisible.
  • I have never seen an unmanaged switch that is also a DHCP server.
  • In any case, an unmanaged switch should be connected to the main router if you want your computers to have Internet access. Then the DHCP server in the main router will work through the switch.

Thank you a lot. :biggrin: It is not a DHCP server, I mean the DHCP service is set up at the main router; and my cable if connected from the said switch is not functioning even though there are LED signals from the switch, so I think my switch is "dead" and I can't reset it anymore.

Failed: Internet ---- Main Router ---- Switch ---- My computer
Works: Internet ---- Main Router ---- My computer
 
You likely have a dead switch or dead a port. Generally, unmanaged switches have nothing to reset since none of the settings on them can actually be changed. The best you can do is to try different ports and turn the device off and then back on.

If that doesn't work, then its time to throw it away and get a new one.

Thank you for your reply,
I did change the ports (all of which work fine (LED signals are all on)), cycle the power to no avail.

Then it's likely a dead switch. Time to go out and get yourself a new toy!
 
Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'
Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
