Wifi password change with the help of command prompt.

[umarcrespo]

Hello,
So I think I am doing the wiser thing of expressing my issue in words rather than posting the whole picture of it. This issue seems complex for me but maybe a walk in the park for the guy with higher knowledge.
So, my sister opened up command prompt and typed in ipconfig/all and some data came up. She took a picture of it and the next day the Wifi isn't working anymore. It shows in available connections but doesn't work on my device. Luckily I have ethernet and I am able to seek help.

What I can say is that she has used that info to change the password, and now she won't say a thing to me. If I am right then help me reverse this problem. If I am wrong, help me still. I'll be grateful.
Thanks.

That should not have enabled the changing of the wifi password, what she's probably done is blocked your mac address, which she would have gained by running ipconfig.

Sorry to say it, but you need to understand why your sister has done this, and what you have to do to make her undo it. Start talking to her.

Running ipcofig will not change settings on your router.

Try restarting the router(unplug the power for ~30 seconds then plug it back in) . If that doesn't with reset it(instructions will be in the router's manual).

Urm thanks for the knowledge. Maybe I'll sound crude so... sorry. It's a personal matter and talking won't cut it out. It's not about talking because...you don't really know what it is about, and I can't really tell you right here about the matter cuz it is totally off topic and off place. Anyhow, there's gotta be a way other than talking right?
Ethernet is working but wifi...nope.

I would have reset the router but it's configuration settings page is locked by a username and pass which is known by my isp. Only they are authorized to make changes on it so, just pressing the reset button is gonna make a huge ass bill that i am not in the place to pay.

I suppose theoretically, if you picked up a small USB wifi adapter, it would have a different Mac address.

Don't let her know you're using it, and don't ever let it out of your sight. Plug it in when you want to use it, and take it out when you're done with it.

This might be only a temporary solution, though. I believe most routers can be set up to handle MAC addresses in two ways:
- blacklist specific MAC addresses - which is what we've been assuming she did to you, blocking MAC addresses she doesn't want to go through.
- whitelist only specific MAC addresses. ie: Listing which MAC addresses are allowed, and everything NOT on the list is blocked. More work, but it's POSSIBLE she did this instead.

If she did the whitelist method, you're SOL. If she did the blakclist method, and then figures out you're using a different adapter somehow, she might resort to going the whitelist method.



A little strange that she'd block your wifi, but not stop you from using a cabled connection.

So, I did try the adapter thing and concluded, the password has been changed.
How?

 

[13thmonkey]

she changed it at the router, that's the only place it can be changed.

 

[umarcrespo]

Alright, so when i type in 192.168.1.1, authentication required. How do I get through that?

 

[umarcrespo]

Although, can I not find the password using my ethernet?

 

[King_V]

By typing in the password.

There is no way around it.

 

[13thmonkey]

You use the password, it's normally on the router, I'm assuming that having physical access to the router is not a problem. If it is a problem then we cannot help you.

 

[umarcrespo]

So, here's the amazing update. Although you guys couldn't help me because I did not tell you all the resources that i had access to.
... [redacted] ...and lo! I have wifi now. Although I really want to thank each and every one for wasting your time for me. I'm sorry and thanks a lot.
I put this thread to rest.
edit:how do i chose my answer as solution? 😛

 

[King_V]

So, just throwing this out there, I'm thinking that you might need to hash out with the family who has access to wifi and who should and shouldn't be restricting anyone...

 

[nigelivey]

Think this is more a family issue than a technical one, sorry.

I'm closing this, and redacting the answer.
