Hi.
I recently purchased an NC10 and trying to connect using a wired connection directly through a cable modem fails. I’ve tried in two different locations, in both cases swapping the ethernet cable directly out of another computer that functioned properly. Wireless connectivity works fine but I don’t have a wireless router and had to test over open networks in the area.
Any ideas what the problem might be? I’ve tried going through samsung’s customer support and was redirected to another dept that’s closed on weekends. Thanks for any insight you might be able to provide.
Have you had the wired connection working previously or has it never worked?
Is the connection definately enabled in Network Connections?
Is it set to obtain an IP address automatically?
The wired connections in both cases were working previously and after with other computers but never with the NC10. The NC10’s set to obtain the IP automatically. In the network connections window under Local Area Connection it says: “Limited or no connectivity General Marvell Yukon etc etc”
If I go into the Local Area Connection Status window I can see that packets are getting sent out but nothing’s received. If I check my Network Connection Details, the following are blank: Default Gateway, DNS Server and WINS Server.
Do you have other computers plugged into your cable router that work ok? I.e. is DHCP enabled on your cable router and is it assigning IP addresses to other computers?
A couple of things to look for. You should be set to obtain an IP address automatically.
Therefore the boxes for DNS etc should all be greyed out.
Check the status of the connection under the support tab. It should look something like this.
Next try going to command prompt (Start, Run, CMD, Enter) and typing “ipconfig /release” and press enter. Then type “ipconfig /renew” and press enter. This will force it to obtain a new IP address from the DHCP server on your cable router.
Hmmm if the LAN port wasn’t enabled in the BIOS then I don’t think you’d see the LAN connection at all in windows.
Feel free to correct me if i’m wrong!
Adatay,
Other computers work okay, but I’ve only got one plugged in at a time. I just swap the cable out from one computer to the NC10 and back. As I’m typing this, the computer I’m typing on is not connected to the internet. Before I send my reply I’ll have to swap the cable back to this computer. The TCP/IP properties are all set to automatic but when I go into the support tab under local connection status I see the following message:
“Limited or nor connectivity
You might not be able to access the Internet or some network resources. This problem occurred because the network did not assign a network address to the computer.”
The details button below that message shows the physical address, IP address and subnet mask, but the default gateway, DNS server and WINS server are blank. I put in the ipconfig /release command and it went through, but the other one brought up the following message: “An error occurred while renewing interface Local Area Connection: unable to contact your DHCP server. Request has timed out. No operation can be performed on Wireless Network Connection while it has its media disconnected.”
After running that, however, the support tab of the local area connection status window changed. It now says, as address type “Automatic Private Address” followed by the IP and subnet mask, but no default gateway.
PanMan,
I don’t know how to check that. I was brought up on macs and aside from gaming with XP under bootcamp I’ve stuck with the mac OS until purchasing the NC10. My primary computer’s an imac.
Thanks for your help.
Hmmm ok so you have a cable modem with only one port. In the long term I suggest you buy a wireless cable router (which will usually have 4 ports on the back) That way you could have both computers (and more) connected to the internet (and wireless if you want). Something like this perhaps. Anyway thats off-topic.
I know very little (nothing) about macs. I suggest you looks at the settings on the Mac and try and mimic them in Windows. It is possible that your cable modem does not have a DHCP server (to assign the computer with an IP address)
If your Mac has a fixed/manual IP address then do the same in Windows on the NC10. It will be fine to use the same IP as the two computers won’t be connected at the same time and therefore won’t conflict.
If your Mac obtains its IP address automatically then I’m afraid we’re back to square one and I’m starting to run out of ideas.
What make/model is your cable modem?
Try updating the drivers for the LAN card from the Samsung website (download them from your other computer and transfer on a memory stick)
It is possible you have an NC10 with a LAN port that just doesn’t work in which case you might need to send it back / off for repair!
adatay,
My plan is to eventually get a better router. Up until now I haven’t needed it. I’ll probably just get something from Linksys. Right now I’m connecting directly into the cable modem.
The setup here and at my home is automatic. I’d tried punching in the info from my mac as well as the one here and it hasn’t fixed the problem. Most recently when I put in the info here I noticed that the router number has one additional place than is allowed for the default gateway. I’m not sure what that means. I can say that running XP under boot camp on my imac at home I’ve run into no issues with internet connectivity and as I understand it, when under boot camp it runs native.
Oh another bit of information. When I was first having these problems I installed ubuntu to see if it would repro under a different OS. It did. Since then I’ve wiped and restored the NC10 as per instructions from samsung so that they could troubleshoot. So atm it’s back to the way it was when I first got it up and running, no additional software.
Is there any possibility the ethernet dock on the nc10 I got could be defective?
edit: Just saw your edit. Thanks. I’ll check that.
2nd edit: Cable modem’s a motorola SB5100 here, I’m not sure what I have at home but this model looks similar to mine.
ah missed you have a CableModem
They ‘learn’ the MAC address of the device which is connected to it. If you want to swap devices that are connected directly to the CM then you need to power cycle the CM first before connecting the new device too it
IIRC the Surfboard has a status page which is access on http://192.168.1.100 (or that may be http://192.168.100.1 ) which shows you the ‘learnt MAC addresses, power levels etc.
Been 6 or 7 years since I did CM support sorry so a bit rusty
you may need to reset the modem if you keep swapping from a desktop to netbook using just the one port on the cable modem.
a friend as the same trouble going from desktop pc to PS3 he needs to reset his modem (switch it off for 30 seconds or more) each time he switches over the ethernet cable.
worth a try perhaps ?
