Qualcomm Atheros WiFi intermittent connectivity after Win 10 updates. |Fixed|

For couple of weeks i have observed this issue that after creators update Qualcomm Wifi adaptor specially 1707 is not working properly.

This all starts to appear after windows 10 creator’s update, as you can see in our previous post we have successfully resolved Audio issue of creator update, 100% disk usage issue of Windows 10 no matter which version it was, wifi network is again part of the same series of issues which occurred after creator update.

System restore and Reset is making it work but just for time being as Windows 10 has its own mind of installing updates which is making PC device manufacturers go crazy.

We tried uninstall reinstall the drivers,tried 3 different version of drivers still not working.

Then we tried resetting the PC to factory settings and fixed the problem.

BUT within two hours Windows got updated and we started facing the problem again.

We identified that the issue is somewhere with Windows creators update.

With some RnD recently we have come to conclusion that Microsoft Windows virtual driver is causing conflicts with it.

Steps to fix it :
1) Run Command with admin rights.
2) Type in below commands.

  • Netsh wlan stop hostednetwork
  • Netsh wlan set hostednetwork mode=disallow
3) Restart the system and check.
Just in case you want to start it again if it does not fix the problem then follow below:

  • Netsh wlan set hostednetwork mode=allow
  • Netsh wlan start hostednetwork
Right now we found it working in some odd cases trying and will check more.

We are still figuring permanent fix…

Changing Desktop icons text font colors | Windows 10 |

Sometimes you may find that the Icon’s text/Name/Font color is too bright or too dark, it is even not readable because of the matching contrast with the background image are being used.

So you may want to change the color of text of the desktop icons in order to read their names.

Sorry there is no such option in Microsoft Windows 10 to change the text color of desktop icons but there is one trick which you can use to let Windows change its color as a workaround.

That is changing background color of the desktop background which will automatically adjust the text color against it and later put back whatever images you want to use.

Issue resolved.

How to do it ?


If you don’t know how to change background color then follow below link by Microsoft :

Ensure changing the solid color not the background image, for example Orange color for black text font color of Icon.

Once you will change it’s color again put whatever background wallpaper image you want to put up over there.

Suffering Password and Fingerprint Stress/Rage?

You’d think with a notebook full of passwords, and 10 fingers registered for biometrics that getting into my computer every morning to get to work would be a breeze. Well, it’s not. For some reason, when I’ve just washed my hands and dried them perfectly my fingerprint swipe just isn’t good enough for my laptop. ‘Swipe from first finger joint’ (or words to that effect), it says. I try four, five times. Then I start yelling. I’m SWIPING FROM THE FIRST FINGER JOINT, YOU IDIOT! After the third yell, Woohoo, suddenly I’m in, and life begins again.

I’m in, yes, but that’s not the end. Popups, ‘sign in to Google for backups and sync’. No, I don’t want to, so rack off. Then I want to sign in to both my Gmail accounts and my Drive accounts so they’re there all logged in and I can swap when I need to swap between them while working, but no! I get signed out of one if I go to the other. What’s the password again? I check the long list in my notebook because not all of them are in my head and I am asked to change them so often my brain couldn’t contain them all anyway. Then Avast wants me to save the password for this service and even IT wants a master password, but I don’t want any of it. I just want to get to work. GO AWAY!

Make another cup of tea and calm down. Some toast? The phone beeps, my index finger has peanut butter on it; I wipe it on a tissue, swipe to unlock the Motorola. Nope. Oh, wipe the finger again, wash hands again for pity’s sake (must register all 10 but haven’t had time) and press lightly. Nope. Press again. Nope. Swipe and try password. At last, they’re all numbers and I remember them, so I’m in. It’s Messenger. I hate Messenger. I liked it when Facebook sent emails and I could instantly read the message without having to log into Facebook with yet another password to see it. So I ignore it.

I check Google and find others suffer from this malady and it’s called Password Rage. More people must be suffering from it now because my search only goes back three years. It seems other people realise technology has created a monster. Hackers have made life harder for us all. It’s true that we already need a password to exist as a bank customer and with the Government. We’ll soon need a password to go to the toilet or have a shower, to leave the house (this is probably already a thing), to eat and sleep or walk the dog!

Computers were supposed to make life easier. What happened to that?

I guess it was always going to happen, this daily password and fingerprint stress and rage, what with the amount of times we have to use them. Results of a survey by Centrify, (whose findings have been mentioned in a story on the ‘Lifelock’ website), quote a UK password management company saying 25 per cent of us forget our passwords at least once a day. They say password rage can lead one to yell (we know that already) cry and yes, throw the odd tantrum.

So what is to be done? The best advice I’ve found is that since humans aren’t good at passwords we need to be more understanding. We also need to get it into our heads that hackers are at this very moment probably out dancing while their super high tech password-cracking programs are getting into our computers. In broad daylight. These boxes can apparently make up to four billion ‘cracks’ A SECOND.

Imagine what they can do with your password once they’ve cracked it. They can try all the social media sites, the banks and credit unions; get into your files, your finances, your health information, CentreLink and other government agencies. It’s like getting into your brain and taking over your body. Well, maybe not quite taking over your body, not yet. But your identity, for sure, they can take that, no worries.

You can always find out if your email address has been pawned or has been part of a breach by going to the website and typing in your email address. I did that and phew! No breaches so far. As long as this site can be trusted, but who’s paranoid?

So I’m advised by all the searches to get myself a password manager. Like, what? Hand over all my passwords to someone else to remember or so their computer systems can be hacked? Yeah, sure. But I’m assured that places such as KeePass, Dashlane or LastPass are all perfectly safe and good. But I groan when I read that the ones in my browser are good too, unless I’m separated from the browser. Another groan, password managers take time to set up, but wait — once it’s all set up you have to remember only ONE password. Sounds like Heaven.

Another option is to use double factor authentication, the same as when I login to my government account and have a text message sent with a code, right. Another piece of good advice from this website is to make passwords stronger, with 12 characters rather than only six or eight. Make it a combination of numbers, letters and symbols and make it not look like a word. Better still, choose five words without spaces such as Rumpencilglassclockpetrol and the hackers will be busy for the next five hundred years trying to crack it.

Next solution to cause problems will no doubt be voice authentication.

How to remove extras options from WordPress dashboard profiles

First you need to create a child theme. Creating a child theme when performing adjustments to your theme’s code can save you a lot of future headache. Child themes allow you to make changes without affecting the original theme’s code, which makes it easy to update your parent theme without erasing your changes. 

Use this plugin to generate your child theme

Child themes work on a file-level. When a file is used during the process of loading a theme it checks if it is present in the child theme. If it is, the content of that file is used. If it isn’t, the same file in the parent theme is used. There is one exception to this rule, the theme’s functions file. The functions.php file in both the parent and the child theme is loaded. 

To remove extras options from WordPress Profiles in the Dashboard, you can simply add codes to your child themes functions.php file. Please remember to move all your custom codes from parent themes functions.php file to child themes functions.php file.

this is the function to add in your file.

[SOLVED] Mysql error – Unknown collation: ‘utf8mb4_unicode_ci’

You have this issue because your server run an older versions of MySQL.

Open your sql script to import with a text editor and replace the collation from utf8mb4/utf8mb4_unicode_ci to utf8/utf8_general_ci

If you use linux, you can do it via shell

sed -i 's/utf8mb4/utf8/g' your_file.sql
-i 's/utf8_unicode_ci/utf8_general_ci/g' your_file.sql
-i 's/utf8_unicode_520_ci/utf8_general_ci/g' your_file.sql

and before load the script, create the database with the  command


If your sql script is for WordPress,  remember to change in wp-config.php:

define(‘DB_CHARSET’, ‘utf8mb4’);


define(‘DB_CHARSET’, ‘utf8’);

and also don’t forget to modify DB_COLLATE with

define(‘DB_COLLATE’, ‘utf8_general_ci’);

How To Upgrade Raspberry Pi Ubuntu Mate

Before doing anything, create a backup. You can restore your server in case anything goes wrong. Go to the shell and start by running this command with no options:

  • sudo do-release-upgrade

If the new Ubuntu has not been released yet, you should see the following:
Sample Output
Checking for a new Ubuntu release
No new release found
In order to upgrade to  the last version  before its official release, specify the -d option in order to use the development release:

  • sudo do-release-upgrade -d

If you’re connected to your system over SSH, you’ll be asked whether you wish to continue.
Follow the on-screen instructions.

You will now see the packages that are going to be upgraded and the changes that are going to be made. Note that the upgrading process can take several hours, and you can’t cancel the process once Ubuntu is upgrading.

After the upgrade has finished, you can confirm your server is running on the new version by executing the command

lsb_release -r
