If you're unfamiliar with interpreting its results, skip Wireshark—it's a specialized professional tool.
It works at 2.4GHz and 5GHz because it actually supports those speeds. Your computer struggles with 5GHz regardless.
He isn't discussing the TCP protocol version the system picks automatically. I'm not sure about that either. I haven't seen a Windows setup use IPv6 before. My ISP in Australia seems to have added it.
It functions with both IPv4 (a standard format like 100.100.100.100) and IPv6 (a modern address structure). If the link supports IPv4 but not IPv6, you may want to turn off IPv6 to test its impact.
Disabled it and there seems to be some improvement. It's unclear if it's just random changes, but I'm fluctuating between 4-10 Mbps. Still not ideal, but better than before. EDIT: Spoke too soon, now it's between 800kbps to 3 Mbps.
@Tabs Funny.. you've challenged a seasoned network expert with just two words: "dual stack". If I'd asked earlier, I'd say it wouldn't really matter, but the details count. I imagine it would involve DNS handling—resolving an IPv6 address would use that format, while IPv4 might get wrapped up. It could be encapsulated or not, depending on setup. Great job!
From a user standpoint, when both IPv6 and IPv4 options are available—through DNS or simply because a non-link-local address is offered—Windows tends to favor one protocol over the other, usually IPv6. This can lead to performance issues because traffic often goes through ISP-managed 6-to-4 servers to maintain connectivity across the internet, even when IPv6 is used for host-side communication. Without these 6-to-4 proxies, minor delays in DNS requests would be noticeable, but the complexity of ISP-level routing makes the situation much more complicated.
Uncertain whether we're connected, but the performance has gotten better, though it varies widely—sometimes under 1mbps, other times near 10mbps.
It’s interesting to discover something fresh each day. This approach often happens on the ISP side without the customer’s awareness. Why would they send everything from 6 to 4? That doesn’t make sense!
