Internet stops working after a while

I have a ethernet connection to a router with a limit of 4 ip addresses and there are 4 computers in my houses, with no one else hacking my internet. recently, my laptop's internet will stop working after a while and I don't know why.

Hi zijincheng,

Do you have DHCP enabled on all the computers? Perhaps IP conflict, is there's only 4 IP limited in your router.

You may try assigning Static IP's on all the computers and see if that helps.

Pls. try assigning Manual or Static IP and see if the issue persist or not.

You may try to Power Cycle your Devices and if that would help.

Please install and run Advanced IP Scanner. You'll be able to see the IP Addressess including MAC's being used in your home network. See if you can find 4 diff IP Addresses.

Switch your the IP to DHCP and pls. provide another ipconfig /all in a text file:
Click on Start => in run or search box type cmd, run as Admin press enter. Open up a command prompt then Copy and Paste these ipconfig /all >c:\ipconfig.txt . Please attach the .txt file to be found in your Local Disk 'C' on your next post.

An update will be nice.
