Improving Wifi via Channel (Frequency) Selection - Rectify Wifi Environment Congestion
article #1400, updated 5 days ago
Here is a very good comprehensive step-by-step discussion:
Mac is listed first, but Windows is well-discussed after, a Linux command-line (!) method is nicely explained afterward, and Android and iPhone afterwards.
The only item I might suggest, is that the 5 GHz band can sometimes produce far better performance, depending on many factors, including the makeup of walls, if and only if both the WAP and all client devices support 5 GHz. I don’t buy or recommend WAPs which do either/or though, just both, and on a client, if I get 4 bars with 5 GHz and 5 bars with 2.4 GHz, I generally see better throughput on the 5 GHz.

An excellent test recommended by Watchguard:
A very good one:
Here’s the first one we saw which was HTML5 only, no Flash or Java:
Here’s a commonly used one which requires Flash:
And another which uses java:
If you are checking this for wifi, we do recommend that you check for and rectify wifi channel congestion as a next step.
Tweaking Windows: the Multimedia Class Scheduler
article #372, updated 8 days ago
The MMCSS (not sure why the extra letters) is a service in Vista (SP1+), 7, Server 2008, and Server 2008R2, which places priority on video and audio data. Here are some good tweaks. Click here for a VBS script, called MCSO, which does everything below automatically.
So we go here in the registry:
open the item named “NetworkThrottlingIndex”, and change it to “FFFFFFFF” (that’s eight F’s) hex. We can do the same for “SystemResponsiveness”.
Then drill further down to here:
and you’ll see a list of folders. Each folder is a “multimedia profile” according to one reference. Each can contain the following:
Affinity dword:00000000 Background Only False BackgroundPriority dword:00000001 Clock Rate dword:00002710 GPU Priority dword:00000001 Priority dword:00000001 Scheduling Category High SFIO Priority High
I kept the “Window Manager” set at the default, and set the rest to the above. According to one reference it is possible to create custom multimedia profiles and use some applications’ capabilities to assign them, I have not tried this yet.
According to one reference, the above changes only activate at reboot. However, I have found that if you restart MMCSS and then Audiosrv, the same results obtain.
Addendum. Have just recently looked into Windows 10 in this. It appears to be a driver, not a service, in 10. Will be investigating further. Not sure about Audiosrv either.

A sample SMTP conversation. Blue is transmit, red is receive; all exists within a command-prompt window. The messages received will vary somewhat, but the initial numbers won’t. The greater-than and less-than signs (< >) are required. The below works fine in Cygwin with ‘inetutils’ installed (which includes ‘telnet’), or in CMD with the Windows ‘telnet’ installed. Linuxes obviously have various telnets! ‘putty’ on Windows will do it also, in telnet mode, port 25, just replace the first line with GUI putty setup.
telnet mail.srcdomain.com 25
220 mail.destdomain.com ESMTP
MAIL FROM: <firstname.lastname@example.org>
250 2.1.0 Sender OK
RCPT TO: <email@example.com>
250 2.1.5 Ok
354 Enter mail, end with “.” on a line by itself
250 2.0.0 Ok: queued as xxxxxxx
Connect PowerShell to Exchange Online / Office 365 / Azure
article #804, updated 54 days ago
The following method is the Microsoft-recommended current one. You may need to use Install-Module instead of Update-Module depending on pre-existing installations et cetera:
Set-ExecutionPolicy RemoteSigned -Force -Scope Process Update-Module -Name ExchangeOnlineManagement Update-Module -Name AzureAD Update-Module -Name MSOnline Import-Module -Name ExchangeOnlineManagement Import-Module -Name MSOnline Import-Module -Name AzureAD Connect-ExchangeOnline -UserPrincipalName firstname.lastname@example.org -ShowProgress $true
The following method is the previous, and is the one which works pre-Windows-10 and/or Powershell before 5.1:
$UserCredential = Get-Credential $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection Import-PSSession $Session -DisableNameChecking
When you’re done, be sure to do the following afterwards, or you may have to wait for automatic session expiration.
