Windows 10 creators update no Wifi Internet multiple driver duplicate Code 12

If after installing creators update internet stops working, open the device manager and check if the drivers are showing errors. Probably you see yellow exclamation marks and multiple entries for the same driver. If you check the error code you will probably have this error [Code 12: This device cannot find enough free resources that it can use.]

This is linked to 945GM chipset, a popular chipset 10 years ago with many intel dual core CPUs.  It seems that it is not fully supported with windows 10 creators update. Hopefully Microsoft will fix this issue.

A possible solution that has been found to work for many people is to plug something into the pcmcia slot. There are cheap usb pcmcia adapters, so getting one of those adapters may be a way to make the laptop work again and get a few extra USB ports. Why inserting a pcmcia card would solve the issue is really weird, but it does.

Another option is to roll back the installation. Press shift key while clicking on restart. Choose troubleshooting and then click on [Go Back To Previous build]. The previous build will only be supported for 18 months, so you may again try after a few months if the creators update is already fixed.

To avoid the creators update from installing automatically you can use the instructions bellow and choose [defer feature updates]

Ubuntu 16.04 LTS network / wifi disconnecting after a few minutes

There are many people having network and wifi issues after upgrading to ubuntu 16.04.

A common problem is that wifi or network stays connected but the browser (firefox, chrome, opera) shows page not found or a similar error after a couple of minutes. Clicking on the network icon and reconnecting usually fixes this but it happens again after one or two minutes.

It seems that there is a bug and IPv6 is creating this issue the solution is to disable IPv6 on your connetion. Most home and business LANs are not using IPv6 so this should be safe.

To disable IPv6 click on the network icon, click on edit conections, choose the connection you are using and click on edit, on the IPv6 tab method dropdown menu choose IGNORE.

This has helped many of our customers. I hope it helps our blog readers too.

Ubiquiti router disable WAN access to GUI

If you do not plan to change settings on your ubiquiti router remotely it is a recommended security measure to disable SSH and graphical interface (GUI) access from the Internet. By default anyone that knows your public IP can try to log-in using the GUI or SSH.

The commands to disable the above as as follows:

configure
set service gui listen-address 192.168.0.1
set service ssh listen-address 192.168.0.1
commit
save
exit

(192.168.0.1 is the default gateway, if you LAN gateway is not 192.168.0.1, you should change the IP to match your LAN gateway IP).

It is also possible to disable SSH completely from the GUI. Click on system tab and un-check ssh access. This will block SSH completely wont work even from your LAN, , only the GUI will remain accessible.

Text file recovery after deleting or quick formatting

If you deleted  a text file or you made a quick format that erased an important text file, first of all, if it is your boot disk do not boot from it again as it may overwrite the sectors where the lost data is stored and now marked empty. If it is not a boot disk, do not write any new data to the disk.

If you followed the recommendations above, there is a good change the data can be recovered. Usually you would like to use Photorec from another computer or from a live Linux CD and save the recovered files to another disk.

However if the text file did not have an extension (text files created with gedit do not have extensions by default), you will not be able to use Photorec. In that case you may try the command bellow from a live Linux CD or from another linux machine.

sudo grep –binary-files=text -C 1000 ‘tex string on the deleted file’ /dev/sdX1 > outfile.txt

You just need to remember a word that was in the text file you are trying to recover. It should be a word that does not come up on any other text file. Then edit /dev/sdX1 and change sdX1 with the correct path to the disk where the erased text is.

Good luck with the recovery! If this text was useful, please do not forget to link to this blog.
