GS108 Switch Uplink Speed Drops from 1000 to 100 Mbps

I have a GS108 that initially negotiates at 1000 Mbps with my ASUS RT-AC68W, but after ~30 min to a few hours drops down to 100 Mbps. I can see this on the router's status screen (vis web interface) and I notice the difference with transfering files from one computer to another (which is how I found the issue to begin with).

 

I have tried a few things to try to narrow it down.

 

  1. I switched ethernet cables from one cat 5e to another. Same problem.
  2. I tried a different port on the router. Same problem.
  3. I tried a different port on the switch. Same problem.

Just a note, every time I tried any of these, the uplink connection went back to gigabit for a time, then dropped down to 100 Mbps. Other gigabit devices connected to the switch and the router are working fine--it is only the link between the switch and router that slows down.

 

Does this indicate the switch is failing? I've had it for about 10 years now. Or perhaps there is something else I should try?

 

Thanks.

Hi @grossner,

 

Welcome to the community! 🙂 

 

If ever the ASUS RT-AC68W router is not yet on the latest firmware version, I suggest you to upgrade its firmware to the latest version then perform a factory reset and reconfigure the settings from scratch.  Afterwards, check if the same problem still occurs.  

 

If the same problem still occurs, if ever you have a spare switch, disconnect the GS108 switch from the existing network then connect your spare switch and monitor if the same problem occurs.  If the same problem occurs, then you need to ask assistance from Asus regarding the router.  Otherwise, if the problem is gone using the spare switch, I suggest you to replace the GS108.
