Hi, found there are multiple unauthorized devices connected to my home wifi and I want to know if there any loopholes that causing this. Here is my home setup 1) using unifi lite 2) using ZTE ZXHN H267A modem from TM 3) I setup another wifi access point using bridge mode with my old streamyx DSL-2750E Dlink modem the unauthorized devices are all connected through the access point of my Dlink model, is there a bug that allow them to hack it? all of them are using xiaomi phone....
now i try to block them by increase the firewall level to high and block their mac address. Did i do it correctly? and is modem default password is good enough? now the default password are using serial number unlike last time all using same password

1. Change your WiFi name 2. Change your WiFi password to WPA2 3. Disable WPS
Don't ask me how to do those things. RTFM or google

If you use WEP on the 2750E or any modem for that matter than it is easily hacked.

And seriously, that's exactly what happened after I helped my friend re-secure her wifi after noticing 10(!) unknown devices connecting to her router!

New or old I see, but i have block their mac address in my ZTE ZXHN H267A modem, so even they can access my dlink modem, they still not getting internet connection.

I wonder, how far people can hack our router? just get password to join? or can even access router to remove themself from blacklist?
