Question Sagemcom FAST 5598

[LeVzi]

I have been given this router by the ISP (Youfibre) as a replacement, and it is WIFI 7 using the 802.11be standard. It's working great on the 2.4ghz and 5ghz bands, but I was under the assumption that WIFI 7 used the 6ghz band too ?

I cannot find any information on this router off the Sagemcom website, just some certificates to do with Youfibre.

I suspect the 6ghz band is disabled by the Youfibre firmware, but I maybe wrong here.

Does anyone know if this router is capable of using the 6ghz band ? Or it is simply a dual band router just using the WIFI 7 protocol ?

Either way, would I benefit from an updated 802.11be wifi adapter ? The one I am using is an 802.11ax only and I have decent speeds and latency, but looking to always drop that latency is something i'm interested in.

Thanks in advance.

A device to qualify as wifi 7 capable, vendor's device must support 6Ghz. No way a vendor will disable 6Ghz support intentionally.

Huh? Even the top rated Wifi 7 router here on Tom's lacks 6GHz, as do most of the cheaper ones. They are called "dual-band" Wifi 7.

I was wrong then. So exactly what was required?

Surprisingly the big new features of 16 spatial streams, 4096-QAM and 320MHz-wide are all optional. But Multi-link Operation by simultaneously using different frequency bands and channels is mandatory so at least we won't see any 2.4GHz-only single-band Wifi 7 routers.

WPA3 is also mandatory in Wifi 7. It was only required in 6E for the 6GHz band.

It says Wifi 7 dual band gateway. So very likely only 2.4Ghz and 5GHz.

Don't get too stuck on latency numbers. The so called "lower" latency in wifi7 is extremely small. If you were say saving 100ms of latency that you might see in real world usage. a couple ms at most you will never be able to see other than with some testing tool.

The largest issue is that all wifi is subject to massive latency spikes. This spikes and packet loss is what you see causing problems in online games.

No matter what they do there is no solution to the latency spikes in games when you use wifi.

Hard to say which is better. Games do not actaully need more bandwidth. Most use under 1mbps. Using the more dense data encoding methods athough they give you more bandwidth this also means they are more suspetable to intference. They do retransmit the damaged data faster.

Best is always use some kind of wired connection for online games.

That answers my question, its dual band. That is fair enough.

tbh all fps games are pretty decent just on the 5ghz band and I don't get much lag at all, sometimes none.

So I doubt i'll benefit anything from a newer receiver unless I go with a tri band.

Thanks for the reply.
