Wireless adapters 5.8ghz vs 5ghz

[Randomgamingguy]

I'm looking for a wireless dual band adapter right now for my laptop which only supports the 2.4ghz channel and I want to use the 5ghz channel since my laptop is just in the next room from the modem. My cable modem is a Netgear N600 model C3700 that supports 2.4ghz and 5ghz wireless channels. So while browsing wireless adapters online I noticed the dual band adapters say 2.4ghz and 5.8ghz compatible. So is there a difference between 5ghz and 5.8ghz wireless adapters or am I fine if I just buy a 5.8ghz adapter for my laptop?

There's no such thing as 5.8GHz for WiFi networking.

The 5.8GHz band is used on remote control devices, TV video sender units etc

WiFi networking uses only 2.4 & 5GHz

Actually the poster has a point. I've been shopping for one on Amazon and about 90% of them are saying 5.8Ghz. Why are they all saying this if what you say is true?

See Eeero 2nd generation. It supports 3 bands: 2.4, 5.2 and 5.8. I am trying to research what is 5.2 vs. 5.8.
With this Eero we can't say there is no such thing...

I've bought 2 different adapters in the last month. The first one was from Asian company (EDUP AC600). This adapter required hoops to jump thru for 10 to see it. After getting it to see the 5ghz channels, the download speeds were at under 10% of where it needed to be. I ended up getting a Ourlink AC600. You do not want Windows giving you the driver on this one either. I had to go the website on this one as well but it's driver is performing at the optimal speeds...so far.

And fyi, both were advertised at 5.8ghz. To my knowledge, my Netgear is not reported as a 5.8 ghz. However, from what I have read, 802.11 ac goes to 5.725ghz. But there still seems to be conflicting articles on what's what.

I think we can agree that Phillip did not bother researching when he posted his little response.

Plus, it's very easy to find a full list of wifi channels: https://en.wikipedia.org/wiki/List_of_WLAN_channels

In the US, 5170-5835 MHz are part of the range of frequencies with WLAN channels in the U-NII rule sets.

The original poster's C3700 router is listed at fccid.io/PY313300241 as operating at 5180-5240 MHz and 5724-5825 MHz. The center frequencies for DFS (where/if offered) cover 5180-5720 MHz.

It may be that some manufacturers try to market DFS as its own band, and others don't feel it's necessary to highlight that. "Tri-band" is also sort of meaningless as marketing hype these days since 802.11ad would include 60 GHz.
