5Ghz WiFi and Windows 10

NullLeave a comment

I have been having issues with devices maintaining connections to my 5Ghz SSID on multiple devices. After the latest Android update, it seems my phone is able to maintain reliable 5Ghz connections but my Windows 10 laptop was still having issues. After some searching I decided to update the driver and see if it made a difference. Its still too early tell for sure, but it seems the new driver is doing better. The AP in question is a Synology RT2600ac with SmartConnect disabled, running 2 separate SSIDs for 2.4Ghz and 5Ghz. Support has been of absolutely no use. They repeatedly stated they didn’t see any disconnects in the logfile dumps.

Normally I would only stay connected, if I could connect at all, for a few minutes.

System Manufacturer:LENOVO
System Product Name:20L50017US
BIOS Date:05/22/2018
BIOS Version:N24ET39W (1.14 )
OS Build:17763.1.amd64fre.rs5_release.180914-1434

The driver version I was having an issue with:
Device: Intel(R) Dual Band Wireless-AC 8265
Current driver version: 20.70.11.3
Driver date: 6-29-2019

The latest version in testing:
Device: Intel(R) Dual Band Wireless-AC 8265
Current driver version: 20.70.12.5
Driver date: 8-26-2019

I ran “netsh wlan show wlanreport” to get some insight on what was going on.
BOLD items below are 5Ghz specific errors and warnings. The 2.4Ghz SSID has been working without issue.

Session Success/Failures
Status Count
Successes 2
Failures 10
Warnings 16

Disconnect Reasons
Reason Count
The driver disconnected while associating. 8
The network is disconnected by the driver. 7
The network is disconnected because the user wants to establish a new connection. 4
The network is disconnected by the user. 2

The error I was repeatedly getting while trying to connect to the 5Ghz SSID is:
Failure Reason:The driver disconnected while associating.

The red Xs in the image below are all dropped connections to 5Ghz.

http://www.linuxquestions.org/questions/debian-26/how-do-i-get-apt-get-to-completely-uninstall-a-package-237772/
http://www.rootkit.nl/files/lynis-documentation.html

apt-get install deborphan debfoster

#apt-get remove –purge package
#apt-get clean

the later will clean the /var

#debfoster

will show files and libraries still left after the apt-get remove –purge, if you don’t recognize a library, keep it, later on, deborphan will give you a list of ‘orphaned’ libraries that are hanging with no use, and are safe to nuke.

if you make a mistake with debfoster, type ‘u’ and will ask you again if you want to keep it. When you are thru with it, invoke deborphan.

#deborphan

will give a list of libraries that are hanging just taking space, to get rid of them:

#deborphan | xargs apt-get -y remove –purge

when thru with that:

#apt-get clean

recently after a dist-ugrade to sid, it installed emacs21, i removed it, and debfoster found some files like emacsen, etc.

aptitude purge ~c
apt-get autoremove

Also you do not need the “remove” when doing apt-get remove –purge package, just apt-get purge package.

deborphan | xargs apt-get -y remove –purge

To remove all orphaned data packages run:

deborphan –guess-dev | xargs apt-get -y remove –purge

To see all the orphaned packages on your system run:

deborphan –guess-all
