Question

pc refuse to work on the switch

Mar 3, 2018 7:12AM PST

I have a weird problem with one of my pc's on my network

it refuse to work on the switch, when I connect both of them with cat5e cable the lights on the ethernet ports at the back off the pc and the corresponding port on the switch are off, no blinking, just nothing. However if I connect this particular pc to the router/modem it works!

btw I don't think that it is anything wrong with the switch becase I have connected other devices on it including other pc's without problems.

Switch: D-LINK DGS-1100-08
Router/Modem : Speedport W 724V Type Ci
PC mobo: Gigabyte GA-G41M-ES2L link

What about drivers?
Mar 3, 2018 7:43AM PST

I'm running into more and more folk that haven't heard about drivers for the motherboard and network. Tell more. If this work is done, be sure the network chipset on the motherboard (it's not a card) is enabled and try again. Some onboard devices are dead so we slip in a network card, install drivers and re-test.

default windows 10 drivers for the network adapter.
Mar 3, 2018 8:13AM PST

like I said the pc CAN connect on the network via the router/modem but NOT with the switch.
Also it have the default windows 10 drivers for the network adapter.

At least you have more to try now.
Mar 3, 2018 8:24AM PST

There are switches and network cards that have Auto-MDX so it is very possible that there is an issue there. But running on Microsoft's choice of drivers at least gives you something to try now.

I have already try the usuals

I have already try the usuals, power cycle, try different ports on the switch and cables.
I don't know what the Auto-MDX is and if there is an issue there how I am going to find out and fix it?
Also worth noting is that this particular PC when I connect it to the router/modem it limits itself to 100Mbps instead of 1000Mbps.

This means you install the motherboard and LAN drivers from the maker. I do occasionally run into owners that can't do that. They have to get it done by whoever supports them.

motherboard is old
Mar 3, 2018 1:30PM PST

because the motherboard is old, Gigabyte doesn't have any drivers for w10 so I have to rely with whatever drivers the windows provide

default settings
Mar 7, 2018 12:13PM PST

The switch is at the default settings

You have to configure it.

It's an advanced setup. I can't guess what settings you need but a standard switch would be best if the gear is too advanced.

Have had similar happen
Mar 4, 2018 5:34AM PST

and still haven't figured out why. In my case, the PC worked fine in my home but not in the school in which it was placed. What it came down to is that, when connected to the switch in the school, the network device was being misidentified. When I'd bring up device manager, the network device was offset with a failure warning that it could not start because it did not exist. To make it work again, I needed to highlight the device, got to "Actions" and select the option to re-scan for hardware changes. When I'd do that, the Intel network device would properly identify and work just fine. This was also an older MB on a PC that was, unfortunately, coaxed into upgrading (I say downgrading) from Windows 7 to Windows 10. Eventually I replaced the Intel device with a cheap Realtek add-in card. I had to install the Realtek drivers and tell Windows 10 to never again update hardware drivers on the machine. So far, so good. Good luck to you.

PS. Forgot the usual.

When you move gear around these switches may not figure it out. You may have to power cycle them.
