Discussion Overview

The discussion revolves around troubleshooting an unresponsive unmanaged switch, specifically a Cisco Linksys model. Participants explore issues related to DHCP functionality, connectivity, and potential hardware failure.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant reports that their computer cannot retrieve an IP address from the switch set up with DHCP mode, while it works fine when connected directly to the main router.
  • Another participant notes that unmanaged switches do not function as DHCP servers and should be connected to a main router for Internet access.
  • Several participants suggest that the switch may be dead or that a port may be malfunctioning, as the settings on unmanaged switches cannot be changed.
  • One participant mentions that they have tried changing ports and recycling power without success, reinforcing the idea that the switch is likely non-functional.

Areas of Agreement / Disagreement

Participants generally agree that the switch may be dead or malfunctioning, but there is no consensus on the definitive cause of the issue, as some explore the possibility of a dead port while others emphasize the switch's limitations.

Contextual Notes

Participants express uncertainty regarding the functionality of the switch and the implications of its unmanaged status. There are unresolved aspects concerning the specific failure of the switch or ports.

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!
