GS305P bocks connection to Internet

Unable to connect through this unmanaged switch. Direct to Comcast modem is ok. The switch is used for a 4 camera surveillance system on Windows 10.

Just a little bit confusing. Four cameras and a PC and a Comcast Modem - with just five ports?

Does this Comcast modem also serve act as a router, serving the LAN for DHCP, assigning private IP addresses to the cameras and the PC?

[POEsystem1246]

I’m sorry. 4 camera capable. I only have 1 camera. The switch is used on the PC. The switch is connected to the Xfinity router/modem. The switch is only connected to Xfinity periodically to update, then disconnected.

“Does this Comcast modem also serve act as a router, serving the LAN for DHCP, assigning private IP addresses to the cameras and the PC?“

Yes. The modem does everything but I believe I need to do some stuff in the PC surveillance app and Windows.

Please tell us more about the switch link and activity LED.

Does the PC get an IP address assigned from the router DHCP server? Show the ipconfig details

C:\>ipconfig

How is that single camera connected - do you see from the unknown recorder software if the camera is on that very same IP subnet, too?

Can you login to the Comcast router via it's LAN IP, and locate the list of connected devices - MAC addresses and LAN IPv4 addresses?

It’s flickering amber on the port to the Comcast router and amber/green to the camera. I’m on Ubuntu now.

Consult the NETGEAR 5-Port Gigabit Ethernet PoE Unmanaged Switch GS305P (55W) and 5-Port Gigabit Ethernet PoE+ U... for the LED indications.

This has no relevance, the switch LED indications are the same.

Not sure what you expect here from the Netgear community members now. You have not told us what camera, what recorder software, of the cameras and the recorder does get IP addresses assigned from the modem-router, not even mentioned you are able to access and login on your router LAN IP, to check if the cameras for the IP address(es) on the LAN. One would imagine this Ubuntu system is kind of workable, you can login, open a Web browser, and access the router Web UI - a feature almost certainly available on your Comcast modem/router - assuming it's really router, and not just a cable modem.

Any simple computer with a graphical desktop, and a Web browser would allow the Internet access even in that case. Start letting us know what Comcast cable modem or modem-router you have in place, and some experienced user could chime in here.

An workable switch won't block any Internet connection by the way.

I have the Comcast cable modem with WiFi and 4 Ethernet ports (3 available). The POE camera is an Amcrest IP5M-T1179EW-36MM and the unmanaged switch is a Netgear GS305P. IIR, the issues began when I connected the switch. I’ve reconnected the camera directly to the Optiplex 7040 (1 Ethernet port) to see if Xeoma (surveillance software) can see the camera.

Of the unmanaged switch, I see that ports 1-4 are marked as POE and #5 is not identified as for POE.

When Xeoma can see the camera, I would like to know how to connect the unmanaged switch to the Ubuntu box. At that time I’ll look at the cable box’s IP settings.

Since port 5 is not PoE supporting, I would connect the GS305P to the host router using port #5. Connect any PoE ethernet devices to ports 1 thru 4 on the GS switch. Connecting other non PoE devices, PCs or laptops, to the host routers LAN ports and then you should be able to access devices that are connected to the GS switches PoE ports for there web pages.

On IEEE industry standard compliant PoE, PoE+, and PoE++ switches (802.3af, 802.3at, 802.3be), there is a signalling and/or handshke before poower is applied to the port, the line, and the PD, the powered device.You can connect and Ethernet device to any port, regardless if its  PoE port, or not.

Things might be different on cheap "passive-PoE" systems.
