Hi there,

I run a new i7 8700T desktop with Win 10 Education installed. All drivers and Windows are uptodate. The wireless Internect connection remains intact but webpages stop loading. Or they timeout often. Through trial and error and web searches I found that if I run the following script, one by one, on CMD, the problem get resolved for sometime only to run into the problem later again.

ipconfig /release
ipconfig /flushdns
ipconfig /renew

In the same room, I run a Surface Pro machine (low specs, Win 10 Pro) with absolutely no wireless Internet issues. So it can't be the router that's playing up.

Any thoughts on how I can get this solved please?

Thank you!

Where do I find the 'DNS record'?

When pages do not load, it says DNS error or proxy error. Settings are exactly the same in the Surface Pro which works fine but the desktop doesn't.

Cheers.

Sounds like a problem I had/have on a windows pc that I installed a tp-link wifi dongle on.
It worked fine on windows 7, but then I reinstalled the pc with windows 10 a year or so ago.
Then the fun began.
The install used windows drivers and appeared fine, but then would do what you describe. Sometimes it would 'connect' to the wifi SSID, but show no actual internet connection. Usually, turning the pc's wifi off/on would fix it. The problem often happened on waking from sleep, but sometimes at random times.
I checked the tp-link site for drivers, but this particular model had nothing later than windows 8.

I managed to install the old drivers despite windows not making it at all easy, but it worked faultlessly for quite some time until a windows update decided to 'update' the drivers with some windows driver. Then the bad behaviour above returned. I found how to block windows from updating that particular driver and it's all good again.

Anyway - I would suspect it is a driver issue - check if you can find the latest driver for your wifi hardware.
I saw some suggestions about disabling power saving on the wifi connection as well.
See : https://support.microsoft.com/en-us/help/928152/you-may-experience-connectivity-issues-or-performance-issues-when-you
It might give you an idea on what might be happening.

In Win10 settings, advanced network settings, there is an option (a button) "Network Reset" you could try that....

Have you tried start-> restart a couple of times (not shutdown then restart)?
Also just double check your windows updates manually again before doing that.

Many thanks for all the responses!!

Before I started this thread I had tried the following, none of which were a permanent solution.

Restarting the machine
Stopping and then starting the machine
Unchecking the power save option in the WiFi adapter
Network reset

What was a temp solution was typing the ipconfig script mentioned in my first original post. It was a pain to do it many times over the course of a day.

Following the lead from @robjg63 I changed the power management of the computer to maximum performance! This worked! Yay! Finally! Thank you heaps!

I notice that @K8Toledo has directed me to the Intel documentation. Thank you. I shall follow that up too.

Thanks again everyone!

What this tells me is that the computer has problems coming back from sleep or hibernation. This is likely a driver problem - as per the Intel documentation updated drivers fix this kind of problem so I would look into that.

It fairly much points to a driver problem I think. That's your best course of investigation at this point.

Hi All,

Sorry for the delayed response.

I updated to the latest Wifi-adapter router (2020 Aug version). I didn't see a change in response. I tried toggling between maximum performance and balanced but still not much of a difference. Internet would work initially but drop to a slow speed down the line. This went on for a couple of days.

However, now it is working well! It has been working really well over the last few days now. I didn't know it takes the machine a few days to get better lol. It is now going well even under the balanced power option.

Thanks everyone for all the help! :)
