I generally have high latency when browsing web from my home internet connection. The connection itself is reasonably fast and I normally get ~120 Mbps of download speed, but the latency is often in the realm of several seconds.

The internet connection I use is a fiber by Australian NBN network and I live some 200m from the exchange. I'm located in Perth, Australia, but these latency issues exist even when accessing Australian websites.

Initially, I thought that the issue was with my modem/router which is a pretty cheap model. But when I use a VPN (through ExpressVPN) the latency issues disappear even when I use a VPN server that is physically very far away, say, Seattle.

What could be the issue here? I don't want to spend money on the new modem/router if the issue could be with something else. What diagnostics should I run to identify the cause of the latency? (Win10 PC).

maybe the DNS you are using, when not on VPN, is slow.

How did you measure your latency?

one quick way to test it is to ping a URL and then its equivalent IP address like:

ping google.com
ping 172.217.169.14

Ping time should be almost the same for both otherwise your DNS is slow.

Mind that 172.217.169.14 is a European server, you should find a google IP from Australia by querying your DNS. In Linux you do it with "dig google.com"
