Alienware 17 R4 2017 review
I have an intermittent problem which has just resurfaced recently. On startup I get a warning on the network access icon that the internet is not connected. On running resolve problems in the network and sharing centre the connection is made. The problem found message is 'local area connection does not have a valid IP configuration' fixed. When I restart, the problem reoccurs. My router is wired LAN connected.
Open the Services window ("Start > Run", type SERVICES.MSC and click OK) and double click the DHCP Client entry to open its Properties sheet. Make sure the service is "Started" and that its Startup Type is "Automatic".
If that's all OK, and the PC is continually failing to get its IP address automatically, you could give the Local Area Connection a fixed IP address. Post back if you need instructions on how to do that.
I should have said when you have done what I said in my first post
net stop dnscache and press enter
net start dnscache and press enter.
Thanks mgmcc The service is started and the startup type is automatic. Perhaps I could try a fixed IP address if you could post instructions.
Rawprawn - tried your suggestion - no luck!
>>> Perhaps I could try a fixed IP address if you could post instructions.
Firstly you need to know the IP address of your router. Open a Command Prompt window ("Start > Run", type CMD and click OK), type in...
...and press Enter. This will display details of all network adapters installed in the PC. Look for the address of the DEFAULT GATEWAY and that's your router's address. Make a note of it - it will probably be 192.168.x.1 but the third octet (number) varies between makes.
Now go into the Network Connections folder ("Start > Run", type NCPA.CPL and click OK), highlight the entry for the Local Area Connection, right click it and select Properties.
In the Properties sheet that opens, click the entry for "Internet Protocol Version 4 (TCP/IPv4)" and then click the Properties button. Click "Use the following IP address" and type in...
IP address - 192.168.x.5 (where 'x' matches that of the router's IP address)
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.x.1 (the *ROUTER'S* IP address)
DNS Server address - 192.168.x.1 (the *ROUTER'S* IP address)
(Leave the second DNS server entry blank)
Note: To revert to automatic IP addressing, set *BOTH* IP and DNS sections back to obtaining their addresses automatically.
I followed your instructions but got an error message 'another computer on this network has the same IP adress as this computer' so coudn't apply the settings.
ipconfig /flushdns remember to leave a little gap between ipconfig and the forward slash or it will not work.
it should tell you DNS cache has been flushed if so reboot and see if it works any better.

I selected the address 192.168.x.5 thinking it would be a safe bet that the address ending in 5 wasn't already in use in the network. Try changing to 192.168.x.20 (again with the third octet matching that of your router's IP address).
