I'm new this forum as well as new to my 2750u, though I have owned it for 2 yrs. & still don't have a clue as to settings. All I know is someone set up it up, & it worked. Seems with my age I don't necessarily want to learn anything new. However when there is a problem you want solved, you must.
A while later I noticed I was crawling with piggy-backers in range of my Wi-Fi. I went inside & thought I limited access to only my 4 devices, which seems to be holding true, & changed my password.
Lately I wanted to look at something in settings, only to realize I didn't have, or remember the log-in password. I went to the shop who built my custom desktop, & upgraded my 2008 HP laptop, as they have been helpful in the past with everything caused by me.
They said go to your svc provider, I went, they said we can't recover it, but if you have to reset the modem you'll need our password to reconnect as though it's your first time. They sent me back to the shop where I got it. I talked to their techs, the last thing I wanted to do would be to reset it not knowing anything about setting it up. & the last thing I need would be not to have svc. since I live in a foreign country.They said there is nothing else you can do, but bring it to us, they would reset it.
For the last 3 days I have been searching for a way to recover the password & avoid a complete reset. A just now I found one. A small free file I found on goggle, in less than 2 min. I had my password back. Though I don't know if I can name it according to forum rules. If I get the OK from the OP's I'd be glad to share it.
In order for it to work you must have a backup of settings stored. Lucky for me I did one after I changed the password. I am so happy to have it back, now I don't remember what I wanted change. Tried telling myself, don't worry about until I have a problem, which I wouldn't know how to correct anyway. But at-least now I know how important it is to me to start learning more about it..
