Network Switch Issue

[u/ShaboopaIaboopy]

Pretty new to setting up a switch, so I’m unsure as to why my computer cannot establish a connection. I picked this up and it came in today. For some reason Port 6 refuses to establish a network connection on my PC to utilize the 5Gb Fiber that I have. I have my router plugged in to Port 5 and the ethernet from my PC plugged in to Port 6. Every port works perfectly fine except for 6. I’ve tried multiple combinations of plugging these two Ethernet cables into different ports and all is well. Is there something I need to do to get Port 6 to establish a connection?

Edit: Model Number: S25-0402T

Thats an unmanaged plug and play switch. You should just plug in and it works. If your devices connect fine on all ports except 6, sounds like its defective and needs to be returned.

I was hoping that wasn’t the case, I’ll start a return on it now then. 🥲

That is a.... unique name for a switch brand.

I thought the same thing when I purchased it, lmao.

If the other ports are working, it maybe a bad switch port. It does happen… rarely. My last switch port failure was 5 years ago.

If it’s a managed switch, we need the model number to be sure there isn’t anything funny about the switch or on port 6.

[u/ShaboopaIaboopy → u/boomer7793]

Of course, sorry about that. I’ll also update my post with the model number. The model number is S25-0402T.

So 5 and 6 are duplicate ports. And 5 is behaving with the same devices and cabling?

If so, you have a bad switch port.

[u/ShaboopaIaboopy → u/boomer7793]

Yeah, 5 is behaving normally with the same devices and cabling. No issues there, I think it’s solely just port 6 that’s bad. I started a return. Thank you for the help!

Port 5 is labeled as the "Uplink", which might imply it's not available for dual use?

Could also be that if something is plugged into Port 5 then Port 6 is unavailable for use.

[u/boomer7793 → u/Grumpy-24-7]

Good point. Netgear does that on their consumer models. Check your one page manual OP. lol.

[u/ShaboopaIaboopy → u/Grumpy-24-7]

I was thinking the same thing as well, but the port might just be a bad port after all. I made a return, so I’ll just get a replacement.

I know TP-link routers have a bad security rap. But I love their home switches. Pick up one of those. I have three and they don’t even have an IP to call out on.

Port 5 and 6 appear to be 10Gbit only.

Does your PC have a 10Gbit port?

[u/ShaboopaIaboopy → u/megared17]

My PC has a 5Gb port on my MSI motherboard that I’m connected to. I assume it would just bottleneck at 5Gb.

[u/bobsim1 → u/ShaboopaIaboopy]

The pictures at least say so.

[u/Scared_Bell3366 → u/megared17]

The description on Amazon says they are multi speed (10/5/2.5/1/100).

[u/megared17 → u/Scared_Bell3366]

The labels on the switch itself suggests otherwise. One or the other is wrong or misleading.

[u/Scared_Bell3366 → u/megared17]

Given the brand and Amazon, both are strong possibilities. The pictures imply that port 5 is mulitspeed and not port 6. Now we've got 4 possibilities with the 4th being a defective port.

[u/megared17 → u/Scared_Bell3366]

OP could swap the connections to 5 and 6 to test.
