No internet on bootup - strange new behaviour

Hi, first thought: have you tried disabling Fast Startup? (Fast Startup affects a cold boot, not a restart so fits the pattern).

Have you tried rt clicking the taskbar icon when there's no connection, and clicking Troubleshoot..?
Not suggesting that as a solution, but it might tell you more.

I'm guessing the relevant driver isn't being loaded when you boot up with no connection- check that in Device Manager.

... disabling/enabling the adapter is not an option.

1 Why not?

2 I used to have to do that when I saw diagram B in a couple of computers.
I wrote a batch file for convenience.
DisableEnableWiFiCard batch file - post #9 - TenForums

3 Please comment on the notion that your WiFi adapter driver is at fault - you might need to update your Bios & re-install the WiFi adapter driver.


Best of luck,

I'm sorry. According to my notes and a printout made at the time, I posted my batch file in post #9 of that linked thread [which now only has 6 posts in it].

The text of my post was:

Try3 said:

I have a script.
- It disables then re-enables the WiFi adapter
- It automatically detects the WiFi adapter name then uses that in the relevant commands.
- It assumes that there is only one WiFi adapter. This avoids having to include checks of multiple adapters being detected.
- I run it from an Admin shortcut set to run minimised.
- The two netsh commands are the ones that necessitate the Admin permission.
- I do not need any delay between the disable & re-enable commands but I added a remarked out one for you to experiment with.
- There is no user interaction because none is required.
- I have been using this script for at least six years on multiple computers without any glitches occurring.

Here is the batch file I use.
DisableEnableWiFiCard.bat

Code:

:: This script will enable-disable the last-found WiFi adapter name so is really only suitable for single-WiFi-adapter computers 
:: Written by Denis, Try3
:: The WiFi switch, if one exists, must be turned on
:: I always run this using an Admin shortcut set to run minimised so I don't bother suppressing with @echo off

prompt $g
Set /a Found=0
set FindString=Name
Set UseExpresssion=netsh wlan show interfaces 

for /F "tokens=*" %%X IN ('%UseExpresssion%  ^|   find /i "%FindString%"') do Call :Interfaces "%%X"
GoTo EndGetWiFi

:Interfaces
:: Detect the WiFi adapter name
Set ThisLine=%~1
Set AdapterName=%ThisLine:*: =%
GoTo :EOF

:EndGetWiFi
:: Do the disabling-enabling
netsh interface set interface "%AdapterName%" disabled
     :: If you need a delay between disabling and re-enabling then this is where you'd put it
     :: Sample delay 1 second
     :: TIMEOUT /T 1 >nul
netsh interface set interface "%AdapterName%" enabled
::Pause to check outcome during testing

All the best,
Denis

I've also found a little note saying that it is worth trying these commands [both need to be run as Admin]

Code:

net stop "Netman"
net start "Netman"

I haven't made any note about why I think it is worth trying or where I got it from.

Yours does what mine does so there's little point trying mine.
- Mine adds in automatically detecting the exact name as shown in Change Adapter Settings because I found that easier than always having to talk people through finding out for themselves.
- Mine also dwells for a second between the disabling & the enabling and that might help.

Does Settings, Network, WiFi confirm that WiFi is turned on?
Does Device manager show any warning triangles?

Is my second suggestion any use - post #7 above?

Code:

net stop "Netman"
net start "Netman"
