Hey guys. My HG850a is given to me by TM for my unifi connection. I want to set the VLAN as well. I followed the all the steps until step 5. Once 192168.100.1 responds to the ping, I pressed open immediately on Putty but after many attempts, putty still fails to connect.

I tried taking out the phone wire, WAN cable, as well as the optical cable and then restarting it, but putty still fails to connect. No firewall on my laptop. I tried it with another laptop as well but it was still the same.
