IP conflict, I think it's a hardware problem.

Is this with an ethernet connection, wireless, or happens with either?

Install, or re-install, the latest correct network driver(s).

TCP/IP stack repair options for use with Vista through 10.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8 thru 10: <Windows Logo> + x - Command Prompt(Admin)]

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine after all three commands; no need to boot after the 1st and 2nd.

This is what I have reinstalled if that helps?

resetting it to default would have to be my last resort, since it's not my router. But i will keep it in mind to try.

I did try a static IP for some time. unless there was something I was missing about it. It didn't change anything. Do you know if i have to set a DNS also? because I just left it blank.

If you set a static IP address make sure it's outside of the DHCP scope handled by the router. CHeck other devices for static IP' and also set them outside the DCHP scope. Yes, you'll have to DNS as well. Set the first one to the DNS server which is handed out by DHCP. THat'll typically be the internal IP address of the router. FOr second you can use the one that's first in the router's WAN IP settings. Or you can use, I believe it's a google DNS server @ 8.8.8.8 or 4.4.4.4

Lastly if you router has that ability and I'm quite sure 95% of them can do that now. You can use a Sticky (static DHCP) IP assigned by DHCP server to a device which has a specific MAC address. Those IP's should also be assigned IP addresses outside on the normal scope. For that last option both IP address and DNS should be set for "Obtain Automatically.

I hope I didn't confuse you too much. If so, please ask with any question you may have. If you give me the exact make and model of the router, I'll look it up and see how to set "Sticky" ip's.

Hi FireFlycph

Thanks for your reply. I am a little confused to be honest. I've read a lot of DHCP related topics. but my computer itself has never mentioned anything to do with DHCP, so I don't actually know what it is. But you asked about my router... I have the Sky Hub (not the Q hub, the first one.) could you please help me understand DHCP and setting a DNS for a static IP? I will post a screenshot below of how I believe you want me to set things. Please correct me if anythings wrong with it Thanks for your help

Can you explain how I can achieve this please?

Hi again,

My router is the Sky Hub SR02, and it has 10 devices connected to it (was 9 when it started with the issues.)

Also I have just found where you mean to set the scope (see image below.)

But one thing is that it seems to have stopped (for nearly 2 days now) I don't want to mark this thread as solved just yet, since:

1. It may come back
2. Nothing was actually solved

My last actions was that I set a static IP with 8.8.8.8 for the DNS... It worked for about 6-8 hours, then it went down, and it wouldn't reconnect. so I went back to a dynamic IP and it came back immediately. Since then, I have not had an issue.

I will hold onto this thread for a couple more days. If there's no change I will mark it as solved, and in the mean-time, thank you all for your help. If anything, I've learnt a lot from all of your troubleshooting

Kind Regards

Well, you can do as dckeks says. Which is absolutely fine. As long as you can remember what number you set as starting IP.
Assigning the already assigned ip of 192.168.0.42 to your machine makes no sense to me. You can force it to a new ip.

What I normally do is to set the DHCP scope to, in your case 192.168.0.100 to 192.168.0.200. Then you have 98 addresses you can assign to specific devices. Either as static IP's or as 'Sticky or reserved" IP's

If you want to make it static.
1. Make the change to the IP scope.
2. Set your machine's ip to the following.

a. IP ADDRESS: 192.168.0.2
b. Subnet Mask: 255.255.255.0
c. Gateway: 192.168.0.1

DNS 1: 192.168.0.1
DNS2: 8.8.8.8

And each subsequent static IP you assign will increase the last IP quadrant by 1. So next device will be 192.168.0.3 and 192.168.0.4 etc. etc All other info stays the same.

You can do the same in the ADD STATIC (sticky) RESERVATION.

You'll put the address of 192.168.0.2 . And you'll probably have a a dropdown box where you can pick your device. If so, it should automatically fill in the MAC address. It won't work if your device is set for a static IP.
Anyway you'll put the IP, Hostname and MAC address in and save it. Then that particular IP address will be assigned to the device with that MAC address, every time it connects to that router. Make sure you enter the MAC address in the correct format. Some devices require a dash (-), while others require a colon ) between the hexadecimal characters. (0-F).

It's a little more work to do the IP reservations. But for me it's worth it. But that's a different discussion.

Remember that you'll need to reboot or renew the IP address if you make a change. Easiest way to do this is to reboot the router and the machine. THen you'll know that the routers DHCP cache has been cleared and the new sticky ip will be assigned when you reboot the station.
