Android 14 cannot print on Canon printer

 After updating to Android 14 on my Google Pixel 6, I was not able to print any more using my Canon Maxify GX7050. The printer is connected using the LAN. Android did not detect the printer in the network any more nor did the Canon print app.

How I fixed it:

 I disconnected the printer from the LAN, disabled and re-enabled LAN on the printer an re-connected it to the network. After that, Android detected the printer and I was able to print again.

Dell XPS 15 7590 with Wi-Fi 6 AX1650 looses connection or cannot connect and disturbes surrounding WiFi / WLAN

I am facing WiFi issues with my Dell XPS 15 7590 and the Killer Wireless 1650 WiFi card. Installing latest Windows 10 and Dell Updates, replacing Dell WiFi Drivers by Killer Drivers (Aug 2nd) did not fix the problems.

On some WiFi I only can connect, if I disable ac/ax in the card driver properties or set the 2.4 GHz to 802.11b or  802.11g (Otherwise Windows keeps prompting for WPA key, even if it is correct).  On others the connection frequently drops for 1-2 seconds and then reconnects, even if I am just browsing (no heavy load on the card).

How-I-fixed-it:
Found the solution in the Dell community forum:
https://www.dell.com/community/XPS/XPS-15-7590-disconnecting-Wifi/td-p/7365191 

Found out that Killer AX1650 is based on the Intel AX200NGW:

http://forum.notebookreview.com/threads/killer-ax1650-vs-intel-ax200ngw-which-wifi-card.830169/

I downloaded the Intel drivers for the AX200:
https://downloadcenter.intel.com/download/29003/Windows-10-Wi-Fi-Drivers-for-Intel-Wireless-Adapters?product=189347

I downloaded the driver removal software from Killer:
http://support.killernetworking.com/software/

I uninstalled the Killer drivers and rebooted my computer.
Then I installed the Intel drivers.

In the Device Manager it then looks like this:

Windows 8.1 dropping/losing Wi-Fi/WLAN connection, limited internet access, frequently re-connecting to router/access-point

Title in german:
Windows 8.1 verliert ständig WLAN-Verbindung zum Router / Eingeschränkte Verbindung

A while ago my wife's Dell Vostro 3500 running Windows 8.1 started to frequently drop the Wi-Fi connection to the router AVM Fritz!Box 7390 (sometimes once a minute), requesting a new IP-Adress by DHCP, but still showing limited internet access.

Things I tried, which did NOT fix the problem:
- Updating to latest drivers
- Switching to an AVM USB Fritz!WLAN Stick N v2
- Assignng a static IP to the network adapter

How-I-fixed-it:
I was able to fix the problem by changing settings for the WiFi-Adapter in the Power Options and disabling IPv6.

First:
Windows Key + R, type control panel,
go to Power Options. Click Change Plan Settings,
click Change Advanced Power Settings, then Wireless Adapter Settings,
then Power Saving Mode. Change the Plugged in option to “Maximum Performance”.
If this is a laptop, you might have On Battery option and set it to “Maximum Performance”. Restart computer.
I found thsi hint here:
http://atechjourney.com/fix-wi-fi-keeps-disconnecting-in-windows-8-and-8-1.html/

Second:
In the properties of the Wi-Fi network connection, DISABLE Internet Protocol Version 6 (TCP/IPv6), as described here:

Wi-Fi problems with Windows 8.1 are described in many threads, here are links to the ones i found:

Dell Vostro 3500 loses/lost WiFi-connection / drops out of WLAN and does not re-connect because of overheating

After being on for a few hours, my wifes' laptop lost WiFi Connection and direfused to reconnect. Leaving it off for some time then, WiFi was working fine again.

How-I-fixed.-it:
Monitoring the problem for a few days I recognized that the downside of the laptop was very warm at the time it lost WLAN connection. I remembered having troube with this system in the past due to overheating because of a dusty fan assembly, as described in a previous post: http://how-i-fixed-it.blogspot.de/2013/05/laptop-dell-vostro-3500-turns-itself.html

I disassembled the system and found the heat exchanger filled with dust. I cleaned the whole fan assembly and since the system is much cooler now, also the WiFi is stable.

Computer / Laptop / Tablet / Smartphone does not connect to AVM FritzBox WLAN/WiFi Repeater. It always connects to WiFi Router with slow speed because of different passwords

I set up a AVN FritzBox 7272 to act as repeater for the WiFi of my AVM FirtzBox 7330 Router. The base router showed the repeater as connected. But my devices did not automatically Switch their WiFi to the repeater but stayed connected to the base at very low speed.

How-I-fixed-it:
I found out, that in the WiFi security settings of the repeater my network had a different password than the base WiFi. Setting it to the same Password as on the base box, devices now connected to the fastet Connection available.

German/Deutsch:
FritzBox als Repeater eingerichtet, aber Geräte verbinden sich nur mit langsamer Basisstation.

Ich habe eine Fritz!Box 7272 als WLAN Repeater für das WiFi meiner Fritz!Box 7330 eingerichtet, aber meine Geräte bleiben immer mit der Basisstation verbunden, obwohl der signalstärkere Repeater in der Nähe ist.

How-I-fixed-it:
Die Lösung habe ich hier gefunden:
http://avm.de/nc/service/fritzbox/fritzbox-7270/wissensdatenbank/publication/show/1192_WLAN-Reichweite-der-FRITZ-Box-mit-einem-Repeater-vergroessern/

Die WLAN's in Basis und Repeater müssen die gleiche SSID, den gleichen Funkkanal und das gleiche WLAN-Passwort haben. Dann verbinden sich die Geräte automatisch mit der signalstärksten Station.

Vodafone EasyBox 803 forgets WLAN/WiFi key / Clients can't connect any more / Preset, Default WLAN key is not accepted

On an friend's EasyBox 803 I run into the following problem:
The WiFi was running fine for Ages, but some day he called me because the Client Computers did not connect to WiFi any more. Rebooting EasyBox and Clients did not help.

How-I-fixed-it:
I connect my Computer to the EasyBox using a LAN cable and opened the WebInterface by typing http://easy.box into my browser address bar. Login using your credentials (or the standard ones "root","123456").
Select "WLAN" in the left side menu and change the WLAN key to a new one. Save the data. Enter the new key in the client computers WiFi Connection settings. This fixed it for me.

As a side note:
I then tried to set the WLAN key back to the one printed on the backside of the router. But it did not let me set it to this value because it is not allowed to set it back to the default value once it was set to a different value. So i had to stay with the new key.

How to connect a TP-Link TL-WA850RE 300Mbps Universal WiFi Range Extender / WLAN Repeater to a Vodafone EasyBox 803 using WPS?

A friend asked me to help him to setup his TP-Link WiFi Repeater with his Vodafone EasyBox 803.

How-I-fixed-it:

Setting up the connection using WPS is pretty straightforward:
1. Plug in the repeater to a socket next to the EasyBox and wait until the Wireless and the RE LED are flashing (the RE will turn off after a while)
2. Press the WPS button on the upper left of your EasyBox (the one with the antenna symbol) for min. 2 seconds until the WiFi light on the frontside of the router starts flashing slowly
3. Press the RangeExtender/WPS button on the frontside of the repeater to start WPS setup. RE is now flashing.
4. After some time (can be up to 1-2 minutes), the RE LED should stay on.
5. The repeater is now connected to WiFi.

No Connection / Manual setup:
Plug the repeater into a socket and connect it to your computer using a LAN cable. In your browser address bar type http://tplinkextender.net. to Login use "admin" for username and password. On the status page it tells you, whether it's connected to WiFi or not.
For manual setup, please refer to:

Blue Screen of Death BSOD on Windows 8.1 with WiFi Adapter Intel 4965AGN: DRIVER_IRQL_NOT_LESS_OR_EQUAL in netwlv64.sys

Since the update wo Windows 8.1 I'm getting random BSOD reporting there's an issue with DRIVER_IRQL_NOT_LESS_OR_EQUAL in netwlv64.sys.

How-I-fixed-it:
In the thread
https://communities.intel.com/message/207413#207413
there's a suggestion to use the driver NETw4v64.sys version 11.0.5.32:
http://support.toshiba.ca/support/isg/drivers/common/vista/Intel%20Wireless%20Driver-11.5.0.32.zip

Did this on Dec 4th and there were no BSOD so far :-)

Also here they suggest to use older drivers:
https://communities.intel.com/community/feeds/messages?thread=31441

Here's a little update:
Although the driver works fine without any crashes so far, it stopped me from being able to Internet Connection Sharing with my Nokia Lumia 920 because the driver does not support the FIPS profile!

How to Delete/Reset Wireless/WiFi Profile in Windows 8 / 8.1, WLAN-Profil löschen unter Windows 8 / 8.1

Randomly my Laptop refused to connect my company WiFi. I wanted to delete and re-add the wireless Profile manually to see, if this fixes it. In Windows 8.1, i did not find the wireless profiles manager known from Vista or 7.

How-I-fixed-it:
Steve Sinchak wrote a blog entry how to delete a wireless Profile in Windwos 8 / 8.1 using a command prompt.

WiFi Authentication issues/failed after Standby/Hibernate after Upgrading to Windows 8.1 with Intel 4965AGN on Dell XPS M1330 with Fritz!Box 7330

Before upgrading from Windows 8 to 8.1, everything was working fine on my computer. After upgrading to 8.1 yesterday, it happens, that my Computer does not re-connect to my WiFi after StandBy/Hibernate. I have to disable/enable the Adapter to connect to the WiFi again.
My Router reports that the "Autentication failed" for my adapter's MAC-Address. I have a Fritz!Box 7330 with latest Firmware. The error message is "WLAN-Anmeldung ist gescheitert: Autorisierung fehlgeschlagen".
The Network Adapter is a Intel® Wireless WiFi Link 4965AGN in a Dell XPS M1330.
I went through numerous threads on the forums reporting similar issues with Intel WiFi Adapters, but none of the suggestions fixed my Problem.

The Driver Version displayed for the Adapter is 13.3.0.137, dated 15.08.2010 by Microsoft.

How-I-fixed it:
In the device Power Management settings uncheck "Allow the computer to turn off this device to save power". Since i did this, the WiFi is stable.

Update:
Found out that the same problem occurs with Intel 3945 ABG network adapter. Fix also works for this adapter.
