Ethernet connection drops when uploading to NAS

[joe360]

I have just set up a new home network. The setup is as follows:

1) Basement: Internet (Fibre)-->Optical Network Terminal (Bell)-->HomeHub 1000-->2x Ethernet LAN connections to 1st floor and 2nd floor

2) 1st Floor: Ethernet --> Office Computer (Win 7 Pro)

3) 2nd Floor: Ethernet --> TP-Link Gigabit Switch --> NAS (Synology ds214se)

Everything seemed to be working fine, expect when I would try to upload files to my NAS (from my office computer), it would transfer one file then the network would crash.

I removed the TP-link switch, and tried it again, and it transferred maybe about 200 files, then it crashed again.

Then I tried to connect the basement like so:

Internet (Fibre)-->Optical Network Terminal (Bell)-->HomeHub 1000-->TP-link switch --> 2x ethernet LAN connections to 1st floor and 2nd floor and it's the same problem

Is this problem with my NAS, network or both? Any help is appreciated! (I'm new at networking and am having a pretty rough first go)

Can you elaborate as to exactly what it means "then the network would crash"? What, exactly, would happen?

Sorry for the confusion. When I upload files to the NAS, the transfer hangs, and then I lose internet connection.

Do you have any other devices to verify? This sounds like it is an issue with just your office computer, which means likely an issue with just it.

Now if other devices get kicked off the network or something, then I'd say network issue.

Try different drivers for your network adapter? Try a fresh install of Win7? Try a new network adapter for it?

Good thinking. I unplugged the Ethernet out of my office computer and plugged it into my laptop and everything uploaded fine. (Can't believe I didn't think of that myself, d'oh!)

The office computer is an new install of Win7 (~1 week), I'll try fooling around with the drivers.

**Update**

I think the issue was the Ethernet card. It's 8 or 9 years old and doesn't have native Win7 support. I bought a new $10 Ethernet card, and everything seems to work! Thanks Azazel!

Sure thing. Glad everything is working for you now.
