Raxe500 wifi6e 6ghz network invisible to s21 ultra
Hi as the title says I am unable to see or connect to the 6ghz wifi. I've used their smart connect and also ungrouped so all 2.4 5 and 6 broadcast their ssids. I can't see any settings to tune in the ...
So this is unaceptable. What did they beta test the router with, since the Samsung s21 Ultra is the only dang device that fully supports wifi 6e?
Netgear support have said the 6ghz band is not available in Australia as it is not approved for use. So that leaves me with
- the router was imported from the USA....so it should broadcast 6ghz
-the ultra phone is an au model. So 6ghz may be disabled. Can not confirm this
I had a look at the regulations to see if AU has approved the 6GHz band for WiFi use, and it seems that their government has not even started looking into it.
The UK as well as the EU are currently going through the approval process for the 6GHz band, but has not approved of it yet. So far it seems that only the US has done what is effectively a partial approval where transmit power is more heavily restricted (250mw for the AP and 127mw for client devices).
Overall, it seems like over time, the FCC may loosen up on the arbitrary restrictions, and other countries will have their own approvals.
I never considered the government regulation side of things since for decades, the FCC has been slow to ease up on restrictions compared to other parts of the world, but it seems in this case, the FCC ended up being first to allow that spectrum to be used for WiFi.
- Hi Razor - I wonder whether these bands can interfere with equipment....seems like a long red tape road ahead
While I am unsure how other countries seek to approach it, in the US they have used 3 methods detailed in their report. https://docs.fcc.gov/public/attachments/DOC-363490A1.pdf
The first is just harsh and unnecesary blanket transmit power limits. 250mw for APs and 127mw for clients (can be lower if SDP detects a noise floor allowing for a 3dB or so SNR above the detected noise floor).
The second method is allowing for proper transmit power using AFC 36 dBm for the AP (3981 mW), and 30 dBm for the client (1000 mW). When AFC starts being implemented, it will use the AP's location and check with a list of registered commercial point to point microwave links in the area, and if no one in range of you us using the channel, then you will have access to even better transmit power for the AP than even the 5GHz band.
The 3rd is designating certain channels for indoor use only. The transmit power for the AP is limited to an overall max of 30dBm (1000mW), but they add a further arbitrary limitation of 5 dBm/MHz, thus at 160MHz channel width, you would effectively be limited to 505mW, though it is not clear if that more recently change limit requires AFC indoors, or if it can be used without needing AFC.
Clients in that mode are limited to an overall max of 24dBm (251 mW) and a unreasonably low -1dBm/MHz which makes for a 127Mw transmit power limit at 160MHz channel width.
The rules are likely to change over time, especially if another major country approves the 6GHz band for WiFi use and decided to not be overly restrictive about it, then that may convince the FCC to be more reasonable.
