Cannot access my router settings (log-in) in any way (factory reset'd several times)

Hey everyone, before I start I want to apologize if this is not the correct section to post this thread.

 

The router I currently own is this one (click here) and I simply cannot access my router settings (routerlogin.com or 192.168.1.1) I do get the text box to input my username : password but all the login infos I've looked up in google won't work. Text Box I get to see.

 

I tried multiple sites to check for login info and none work, one of those being this huge "2018 updated" list:

At the beggining I thought it could be my router messing stuff around because sometimes I got a message saying "Your conenction is not secure" so I tried on MS Edge and then on Firefox, no luck either.

 

I decided to contact ISP, blah, blah, for security reasons they cannot give me admin : password (not sure why?) [My ISP provided me this Netgeat router, I didn't buy it by myself].

 

Anyhow I did not care about what they said because I used to have TrendNET router and could access to my router settings with no interference from them; the next big step I did was holding the little "factory reset" until the power light started to blink (Not sure if it's held more time it might do something).

 

After factory reset I got the default SSID and PW of the network, I logged in, and had to "log-in" to the network, the only thing it said was the SSID and PW I already knew and 2 buttons, one was to print all the info and the other one to proceed and "activate" the internet.

 

Tried all the possible combinations of admin : password after factory reset and no luck either, no I'm stuck with a SSID called "SureWest-f1" instead of the custom SSID I want.

 

I remember once after a while (because I gave up and submitting a live chat here required a proof of purchase which I don't have because like I mentioned before, my ISP gave this to me) I remember attempting to factory reset it again like 4+ times, and only ONE of them allowed me to access the router info, I had like 3 options to choose, continue with net, configure settings, etc. (instead of the print thing screen I mentioned before) but amazingly unlucky me something happened and after settings everything I wanted, the save button or whatever it was simply didn't work, didn't have connection anymore, had to factory reset again and since then I haven't ever been able to access my router settings apart from that lucky try. (Not exactly sure WHAT I did that one time, maybe I held the factory reset button longer? Who knows..)

 

I'd really like to access my router settings to change SSID how I want, custom password, and doing some port-forwarding.

 

Please any help is appreciated, my ISP just won't help me, they're limiting me what to do with my OWN router.
