How do I change the network name and password, router's wps won't send ssid, tether app can't find device

Good day People, I've lost my antennas. What connectors are used for them, or where can I purchase replacements? Thanks

I´d like to monitor how many MB of data traveled through the router to the internet each month. How do I do this in my router? Thank you.

Recently router(AX55 AX3000) don't show 5Ghz on mobile phone but on laptop its working, I tried to seperatly wifi GHZ but nothing even reset it Note: I recently added another router of tplink as wifi

I have recently purchased a tp-link Wifi Range Extender TL-WA850RE from an online store in Australia. On the box it mentions as having 3 yrs warranty. Do I still need to register for the warranty. S/N

Is there a list of the wifi routers supporting NordLynx? I am in Australia and use NordVPN when I am working on my client's German servers. Thanks for your replies.
