TITLE Automatically connect to a Wi-Fi network when in Safe Mode With Networking
ECHO ^+---------------------------------------------------------------------^+
ECHO ^| Automatically connect to a Wi-Fi network when in ^|
ECHO ^| Safe Mode with Networking ^|
ECHO ^| V1.0 ^|
ECHO ^+---------------------------------------------------------------------^+
ECHO ^| This script is supposed to circumvent a ^"bug^" that Microsoft ^|
ECHO ^| obviously forgot it exists. Safe Mode with Networking IS supposed ^|
ECHO ^| to be just that^: a minimal boot environment with a fully working ^|
ECHO ^| networking layer. ^|
ECHO ^| ^|
ECHO ^| Well, as far sa Microsoft is concerned, Wi-Fi apparently isn^'t a ^|
ECHO ^| part of the networking layer. Some systems have the WLAN AutoConfig ^|
ECHO ^| service set to Manual, even if the OS is installed on a laptop and ^|
ECHO ^| it obviously has a Wi-Fi adapter. Sure, the service boots up when ^|
ECHO ^| the drivers load and you try to connect to an access point ^|
ECHO ^| ^(network^), but that^'s when the OS is booted in regular mode ^(not ^|
ECHO ^| Safe Mode with Networking^). ^|
ECHO ^| ^|
ECHO ^| Not only that but Microsoft considers this a FAD, LOL ^:D. According ^|
ECHO ^| to them, not having Wi-Fi access while in Safe Mode with Networking ^|
ECHO ^| is a FAD... I had no idea that Wi-Fi adapters are not networking ^|
ECHO ^| equpment, LOL ^:D. ^|
ECHO ^| ^|
ECHO ^| Let^'s say you have to do something for a client remotely in Safe ^|
ECHO ^| Mode. You^'re thinking ^"Hmmm... Safe Mode with Networking^? Should ^|
ECHO ^| work, right ^:)^?^". Incorrect! On some installs, the service won^'t ^|
ECHO ^| run Automatically, on other installs, you have to manually connect ^|
ECHO ^| to the Wi-Fi network that the rig ^(laptop^/PC^) was connected to ^|
ECHO ^| while the OS was booted in regular mode... which basically means ^|
ECHO ^| that, if there^'s no one at the other end that you can instruct how ^|
ECHO ^| to help you connect the rig to the internet, you can^'t continue ^|
ECHO ^| working on the damn thing. Not only that, but since you probably ^|
ECHO ^| booted in Safe Mode with Networking through msconfig ^(Win ^+ R --^> ^|
ECHO ^| msconfig --^> Enter --^> Boot tab --^> Boot options --^> Safe boot --^> ^|
ECHO ^| Network^), when the person that^'s using the laptop^/PC sits in front ^|
ECHO ^| of it and thinks the problem you were working on is solved and now ^|
ECHO ^| he^/she can finally get some work done, guess what... they^'re stuck ^|
ECHO ^| in Safe Mode with Networking. Yep, no matter how many times they ^|
ECHO ^| reboot the rig, the setting is permanent unless you manually change ^|
ECHO ^| it back to not boot in any kind of Safe Mode. And how are you ^|
ECHO ^| supposed to do that if you can^'t actually remote in and switch it ^|
ECHO ^| back. See what I^'m getting at. You have to harass the client ^(who ^|
ECHO ^| might not be tech savvy at all^), send videos or screenshots on how ^|
ECHO ^| to configure back the rig to boot in normal mode, and not only ^|
ECHO ^| that, but the problem you were working on is not solved^! You can ^|
ECHO ^| imagine how pissed off you^'d be if this happened to you... I know I ^|
ECHO ^| would be. ^|
ECHO ^| ^|
ECHO ^| Sorry for the rant, but I just had to vent since it has happened to ^|
ECHO ^| me on a number or occasions and I^'m getting pretty tired of having ^|
ECHO ^| to explain to clients that it^'s not actually my fault, it^'s ^|
ECHO ^| Microsoft^'s fault. ^|
ECHO ^| ^|
ECHO ^| Anyhow, run the script once to install the ^"hack^" ^(with ^|
ECHO ^| administrative privileges, right click --^> Run as administrator^) ^|
ECHO ^| that removes the ^"bug^", run it again to remove the changes and ^|
ECHO ^| revert everything back to the way it was ^(once again, with ^|
ECHO ^| administrative privileges^). A detailed explanation on what ^|
ECHO ^| information the script will need as input follows. ^|

ECHO Enter the SSID (the display name) and the profile name (in most cases,
ECHO they're the same) of the Wi-Fi network you'd like to automatically
ECHO connect to when in Safe Mode with Networking.
ECHO.
ECHO Remember, you're supposed to be already connected to this network while
ECHO you're in normal operating mode, i.e. if the network is protected (has
ECHO a password), you should've already entered the password and connected
ECHO to this network at least once while runnung the OS in normal mode.
ECHO.
ECHO Caption does matter, so make sure you type in the SSID (name) and the
ECHO profile name of the network correctly. For example, ^"Wi-Fi_NetWork^"
ECHO is not the same as ^"wi-fi_network^".
ECHO.
ECHO If you're not sure what's the SSID's name and the profile name of the
ECHO Wi-Fi network, run the ^"NETSH.exe WLAN SHOW ALL^" (without the double
ECHO quotes) command in a command line (Win + R --^> cmd --^> Enter). The
ECHO information you're looking for is in the ^"SHOW PROFILES NAME=*^" part
ECHO of the command's output. An example output follows.

ECHO What you need is the string in the ^"Name:^" row (that's the Wi-Fi
ECHO network's profile name) and the the ^"SSID name:^" row (that's the SSID
ECHO of the Wi-Fi access point). In this example, the profile's name is
ECHO ^"EXAMPLE-NETWORK^" and the SSID is ^"EXAMPLE-NETWORK^" as well (in
ECHO both cases, without the double quotes). As I've stated previously, in
ECHO most cases, they're the same, but double check to see if they are using
ECHO the command I mentioned earlier.
