But if I can only barely catch their networks, won't interference from me to them be low too? Assuming no one thinks hidden SSID is a security feature, so you don't know about them.

Also, the setting is actually 20/40 so should be able to fall back in case of issues? No. It's one or the other. But if the name is 20/40 one assumes that it automatically chooses 20 or 40 depending on circumstances, right?

In my experience, it's a setting in the access point configuration. So, it's either one or the other.

That affects what channels are available, not how they're used. WiFi is an unlicenced service that has no protection from interference, so you can do whatever you want, so long as you comply with the regs, WRT frequencies used, power etc. Also, some of the WiFi channels are shared with other services, which are protected from interference. For example, the lower part of the 2.4 GHz band partially overlaps an amateur radio band. In that range, amateur radio has priority and protection from interference caused by WiFi and other unlicenced uses. Parts of the 5 GHz band are used for navigation and other uses that are protected from WiFi.

If they cause interference to a protected service, the government may make them aware. ;-)

And then the customer will raise hell against the ISP that supplied and installed the gadget. And even remotely admins it.

Actually, in the 5 GHz band, WiFi gear has to check for the other services, before using a channel.

Makes sense... -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" (Minas Tirith))

And the takeaway for me is that 40 MHz channels on 2.4Ghz are at best a stopap measure and I really need to get a 5 Ghz donge onto the Linux desktop, but nobody can tell me whether the dongle will work :)

Which Dongle? I just put a Netgear AC600 Adaptor (Stock number A6100-10000S) which is compatible with the 802.11N spec , 2.4 and 5ghz band, into a Ubuntu machine and its working very well. However I had to download and build the driver (the chipset is rtl8812AU, and ubuntu didn't have a driver that would work). https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git It built ok, after I told the compiler not to fret about 2 warning messages it was interpreting as errors. So if you can find a distro that has drivers its a nice dongle. If you have to build it, its doable. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The ones I am looking at have the RTL8811AU chipset. Is anything known about drivers and firmware for that?

Way too much is known, in way too many places if you ask me. Google "linux wifi supported cards" without the quotes. I'm guessing you are going to end up building that, but its usually not that hard. https://forums.opensuse.org/showthread.php/520599-Realtek-RTL8811AU-Wireless... -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

One final (hopefully) question - what is the best way to disable the existing PCI Wi-Fi card without physically removing it, so I can try a new dongle safely?

Perhaps the BIOS? In my computer, I can turn off WiFi there. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
