Inconsistent connection of devices on switch
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have bought this switch as there is only one port on my Gigaclear fibre modem. I have connected that port to one port on the switch and my Linksys wireless node and my PC to the other ports, all with ethernet cables. However, I cannot get the wireless node and the PC to both connect to the internet, only one or the other, even though the LAN lights are green on all three ports in use. I have read the article on this from your FAQs but do not understand it. What am I doing wrong?

You should test that on your own.
If your Plusnet router has an ethernet port dedicated for a broadband connection it probably would do the job.
But I will recommend you to buy a new decent router. You can alway use the switch after the router if you need extra ethernet ports.

It's quite possible that the reason is your Gigaclear fibre modem is in bridge mode.
Thus only one device connected to its sole ethernet port can have an Internet access.
You can easily check that - connect the PC to the Gigaclear fibre modem directly and check the PC IP address.
If the PC IP address is public IP address then that's the case and you'll need a router to accomplish what you want.

Thanks, have checked it but it means nothing to me. What is a public IP address?

Private (internal) addresses are not routed on the Internet, and no traffic can be sent to them from the Internet; they are only supposed to work within the local network.
Private addresses include IP addresses from the following subnets:
Range from 10.0.0.0 to 10.255.255.255 — a 10.0.0.0 network with a 255.0.0.0 or /8 (an 8-bit) mask
Range from 172.16.0.0 to 172.31.255.255 — a 172.16.0.0 network with a 255.240.0.0 or /12
A 192.168.0.0 to 192.168.255.255 range, which is a 192.168.0.0 network masked by 255.255.0.0 or /16
A special range 100.64.0.0 to 100.127.255.255 with a 255.192.0.0 or /10 network mask; this subnet is recommended according to rfc6598 for use as an address pool for CGN (Carrier-Grade NAT)
So, if the PC IP address is not in these ranges then it is Public.
The other way to check if your Gigaclear fibre modem is in bridge mode is to open this URL in a browser: https://www.whatismyip.com/
Then compare the IP address from the browser with the PC IP address and if they match then your Gigaclear fibre modem is in bridge mode.

Thanks again. Yes the public IP address is the same as my PC IP address, so conclude my router is in bridge mode. With my Linksys Velop hub wired immediately downstram of the router, and the switch downstream of that, everything appears to be working. I guess that the alternative would be to buy a router to put immediately after the modem to give more flexibility and bin the switch? I have my old Plusnet router, would that be suitable?
