wireless networking – Ubuntu 20.04 loses wifi card

I just did a fresh install of Ubuntu 20.04 on an old computer and after 1-2H of usage the WiFi drops and there is no way to connect it back since the prefs show an error message: No wifi adaptor found. (Works again after a reboot).

FYI: The wifi card is an Atheros AR9485 (internal) and is running using ath9k & everything is up-to-date

wireless networking – Need recommendations about Best Budget Gaming headset

I want to buy Best Budget Gaming headset for mostly AAA games or FPS Games with mic.

Which one is best?

And shall I buy wired or wireless? Why I am asking because my Motherboard MSI Z390 ace has 7.1 surround sound which comes only with 3.5mm jack.

Will my Motherboard MSI Z390 Ace will support 7.1 surround sound over wireless Headphones as well?

sports – Wireless Transmit photos to Computer During Events

I shoot sports events. I am using Canon 1dxM3 – I am needing to transfer photos to the computer while I am shooting for clients to view. I am currently doing this with the EOS utility – however – its only decent – but not 100% ideal. I know there are sports photographers that do events that have the images tranferred on the fly. Other than FTP – which seems somewhat overkill for just myself, is anyone having any success with this?? Is there a better software the EOS utility?? I have photomechanic – but not sure it will do what I need. Ideally I need to control the folders the images go into on the computer as well??? I have a wireless transmitter ordered – hoping that may make the job easier for the EOS utility. BUT curious if anyone else has thoughts?

Anyone??? Ideas???

wifi – Canon WFT-E7B II Wireless File Transmitter and Canon 5D Mk III

Does the Canon WFT-E7B Mk II Wireless File Transmitter works with the Canon 5D Mk III?

The Canon website cryptically states the Canon WFT-E7B Mk II has “guaranteed compatibility” with the 5D Mk IV, 5DS, 5DS R. But, doesn’t mention the 5D Mk III. Does this mean the WFT-E7B Mk II is sort of compatible with the 5D Mk III, but not completely? And, if so, what doesn’t work?

Officially, the original WFT-E7B is the wireless transmitter to use with the 5D Mk III. But, as I’ll be upgrading my 5D Mk III to a Mk IV at some point, I don’t want to drop a ton of money on an accessory that then won’t work with the Mk IV.

I’ve email Canon to ask, but if anyone here has any direct experience, I’d be grateful to know.

wireless – Ubuntu (dual boot) can see mobile hotspot but not main network

I can only see other networks including my phone’s hotspot but not my main wifi network.

Everything worked fine up until randomly the connection would be lost at boot and only after restarting the router a couple times (sometimes once, sometimes more) would the network appear and I could connect to it.

my network driver is BCM4352 802.11ac from the bcmwl-kernel-source package.

I tried a lot of the advice online but nothing worked.

wireless – Network icon is not displayed in tray, and no WiFi networks displayed

I am running Ubuntu 18.04.4

I read another question, “Ubuntu 18.04 WiFi Networks are not displaying even though there are 3 nearby”, on AskUbuntu and tried the solution there. It did not work. I still have no visible networks under WiFi settings. Additionally, I have no network icon on my tray. I am, however, connected to my 5GHz WiFi Network on channel 165.

These are the current responses to the commands asked in that post:

This is an annoyance, but not a major issue, unless I take the laptop somewhere else.

samsung – High battery usage (no wifi no apps no wireless)?

I’ve noticed that I lose about 20% battery each hour while my phone is unattended and offline. I check the battery settings and find that no apps are running.

The phone is rooted, and I’m wondering what kind of cleanup I can do in terms of searching for viruses and botnets and doing some kind of deeper inspection of battery usage?
