Hmmm My solution is unlikely to be helpful but there is a chance but it'll need a device already connected (try to borrow a already connected device or try "Uyy! Paconnect may [insert reason mo]! Please)
Ngayon limited ang time mo dahil dito kaya kaylangan mong mag madali
(1) First, visit 192.168.1.1 - it most likely the owners havent visited this site because most will change the SSID and Password or just password
Now second is crucial for this because this is main part to access the setting of the router
(2) Second, Enter the default Username and Password. -
admin & 1234
adminpldt & 1234567890
Ito lng ang naiisip kong possible na default so try mo nalang.
(3) Third, Find the Network setting Network>Advanced/5G Advanced- Part nito ay easy kung may common knowledge kayo dito
Yan Nakita mo na password! Yay!
