Hi,

I have 2 computers connected to the same router, and after some time the laptop loses the ability to access a website and also my Outlook mail is unable to send or receive emails, but I can still ping ok.

The desktop computer (also Windows 10) continues to have perfect internet access.



I have both computers running on Windows 10 for over 2 years, and both running fine with no major recent changes. Windows Updates are auto on both machines, but one updates a few days earlier than the other.



Both computers are Windows 10 Pro 64 bit.

Desktop: Version 1809 (OS Build 17763.503)

Laptop: Version 1809 (OS Build 17763.379)



This has been happening the past few days. When I restart the laptop everything works fine for a while, and I can click on websites, and all works fine.



After some time (I am not sure how long… 30 minutes?) the problem reappears and I am unable to click on a website and my Outlook mail is unable to send or receive emails.



The weird thing is that I can still do a ‘google search’ using Chrome browser and it returns the list of websites as normal, but when I try to click on a website it says no internet connection.



My Outlook mail is also unable to send or receive emails.



I can ping www.google.com and it also works fine.



I have tried disabling BitDefender Total Security (which I have on both computers) but I still can’t access websites.



When I restart the laptop, it works fine for a while.



I tried

Try reinitialising the network states. Run the following commands in an elevated cmd shell:

· Reset WINSOCK entries to installation defaults:

netsh winsock reset catalog

· Reset TCP/IP stack to installation defaults:

netsh int ip reset reset.log

· Reset Firewall to installation defaults:

netsh advfirewall reset

· Flush DNS resolver cache:

ipconfig /flushdns

· Renew DNS client registration and refresh DHCP leases:

ipconfig /registerdns

· Flush routing table (reboot required):

route /f



When I restart the laptop to complete the above actions it works fine for a while, and then the problem appears.



The problem happens either when I connect the laptop to the router with a wired connection, or by WiFi.



The desktop is connected by a wired connection to the router and does not have a WiFi card.



Any suggestions?



Thanks in advance,

Dave
