Unable to connect 2/3 PC's to internet via tplink Switch
Unable to connect 2/3 PC's to internet via tplink Switch
I was attempting to connect 3 PC's (Personal and two servers) via the TL-SG105 un-managed network switch. Beforehand i just connected one server and the personal pc into another switch i have. But i got this switch to accommodate this new server. However it seems as soon as i plugged in and turned on the new switch all of a sudden both servers no longer are able to recognize their cables. Personal PC is running linux mint, one server(the one i had before) is also running linux mint, and another server is running ubuntu 22.04.
-
Home network consists of 1 comcast gateway (modem+router combo) with two ethernet LAN ports. One ethernet LAN port is connected to a seperate switch that functions perfectly for all other devices connected to it, the other is connected to TL-SG105.
-
Personal PC can connect to internet just fine, either threw TL-SG105, or the other switch- I have attempted to plug both servers directly into the other switch and still no link.- Both servers show via ifconfig command that their respective ethernet flags indicate UP, but not RUNNING. Usually this means cable is not recognized. confirmed via ethtool command that link status is 'NO'
-
Swapped cables between all 3 devices on TL-SG105 and confirmed all cables are operational.
-
Reset TL-SG105 multiple times during each swap of cable. And restart network manager multiple times as well as turned both servers on and off again.
Edit: I actually had to double check the switch, turns out i do have the SG105 not the SG105E. SG105E is managed, i have unmanaged.

Not sure if this was resolved or not, but did you check for static IPs on devices? I ran into an issue when setting up the SG108E where even though I had Linux set to DHCP, it was assigning the manual entry. Rookie mistake 😞. Once I cleared the manual entries and cleared the static IPs from DHCP leases it cleared.
Hey, thanks for posting. The issue is not actually solved and it angers me so. I figured it might have something to do with the static ip, but I have Comcast so it literally takes a day for it to stop applying a static ip to a device. I will attempt to do this.
