computer wifi problem
« on: September 07, 2019, 07:02:11 AM »

Seemingly used but good laptop had v.good working WIFI system. After 6 months it stopped working.
 The same WIFI is working on mobiles without any problems ever.
therefore the need arose to use this usb WIFI adapter.

usually its drivers were also installed.
Instructions in its manual said to disable the default windows 7 wifi drivers/adapter.so they
got disabled.
but the laptop is using  default windows 7  WIFI settings.

Remove the external USB adapter then go into Device Manager/View/Show hidden devices and look for any yellow alerts.

if they are only on Network adapters, expand that, right click on the wireless one and select Uninstall and check the box to include software.

Close off Device Manager and reboot then go back into Device Manager to see if it has been reinstated and that has resolved the yellow alert and that you are getting WiFi - you may need to re-enter the wireless password by clicking on the wireless icon then on your SSID and on Connect.

As you have previously been reported for Spamming, I have my doubts as to whether this is a genuine post, but for now I will give you the benefit of the doubt.

this only works for five minutes.This is an endless cycle of restarting to get wifi working again in my computer.i have done that before writing this post.
what is the proof that i am a spammer.Antivirus Programs,to increase its rating/image often give false positives.
The writer of this post is very important person.
Best Regards.

As a Moderator, we have tools to check the credentials of any new members and you were reported twice in August this year for spamming.

For me that was a slight infringement as some that I've checked out have been prolific Spammers.

Some Spammers post innocuous posts as a try out to fuller spamming which can include product links as you have done in your opening post.

From your Device Manager pic you have two USB adapter drivers installed which could cause a conflict.

I would also change your DNS servers from Google's to auto so that it will use your ISP's DNS servers.

Do you have a built in wireless adapter to use instead of the external USB ones ?

Go Start - type ncpa.cpl and press enter when it comes up.

Right click on your wireless one and select Properties then uncheck the box for (TCP/IPv6) - OK - as that can sometimes cause connectivity issues.

Unless you use them, you can also turn off the MS WiFi Virtual Mini adapters with this cmd run from a cmd prompt run as an admin -

netsh wlan set hostednetwork mode=disallow

shutdown /r /t 00

Checking after the reboot should show them as having been removed.

You can reinstate them by redoing the cmd using allow instead of disallow.
Tom.
