    Problems with network converting hostname to ip address


    For the last several weeks. I've been having a problem with Firefox taking several minutes to find and start loading a sites web page. Firefox tends to hang on looking for hostname. Once the site is loaded it still takes several minutes for the site to fully load. I also found that if I ping google.com from a powershell window it takes several minutes to respond. If you open a bash window and ping google.com it respond almost immediately. Also Microsoft Edge seems to work. It opens the hostname very fast. It seems that if is having problems with dns. I used Microsoft network monitor 3.4 to trace what is happening. From the trace I can see that the dns request gets a response in less that a second. But for some reason the application does not get the response for a long time.
    If I reboot the system the problem seems to go away. Yet at some point in time it is back.
    Anybody else having this problem?

    Windows 10 pro build 10.0.18363 build 18363

    Today I had to reboot the system I thought that it would fix the problem like it has in the past. But after the reboot I still had the problem. I also had a problem starting BeyondTV. It would open the starting window then freeze. No matter what I did I could not get BeyondTV to start. So I tried to boot in safe mode. In safe mode it would start. But It would not show any TV channels. The first safe mode boot was without the network. I then tried to reboot in safe mode with network. Again BeyondTV started but would not show any TV. So I did another revoot in normal mode. This time BeyondTV started and I was able to show TV channels. But a ping of google.com from the powershell window was very slow.
    Why is it that Edge can get the google.com web site fast. But powershell can't get an IP address for google.com fast?

    Have you changed DNS server.

    Yes. I tried 8.8.8.8. But why would one DNS server favor Edge over other browsers?

    I would change the router DNS servers this way every device on your network will use same DNS servers.

    I have 4 systems and three of the four work just fine. Just the one system is having problems. Also as stated above doing the ping google.com from the bash window works as you would expect fast.
    The question becomes why are some processes doing DNS requests fast and other processes are slow?

    They all using the same DNS servers but some web browsers faster when it comes to resolving host name.

    When one says faster. Are we talking about seconds or minutes or longer. Because when I tried to go to usatoday.com on firefox and edge. Edge opened the site within seconds. Firefox took several minutes. One would expect that once Edge got the response that it would be cached and firefox would get it quickly.

    Edge is faster but Firefox should keep up it should not take that long have you scanned your computer for malware infections.

    Start Firefox in Safe Mode and see if any one of the add-ons causing slow down.

    Please download Malwarebytes' AdwCleaner onto your Desktop.

    • Double click on AdwCleaner_xxxx.exe to run the tool.
    • Click on Scan.
    • After done scanning, please hit Logfile. Locate the logfile in the Scan tab, double-click on it, copy the information inside of it, and paste it into your next reply.
    • You can find the logfile at C:\AdwCleaner[Sx].txt as well.

    I will have to try that in the morning. It is past midnight here. A few hours behind Turkey. But also remember that powershell was very slow also not just firefox.
    PS chrome is also very slow like firefox.
    Thanks
