dropping WiFi connection Ubuntu 20.04 >> potential bypass solution?

**fortifor44** · October 14th, 2021

hi all,

For close to two years I have been suffering from an unstable/dropping wifi connection because of, I suppose, my network adapter (see for full details below). Like a pebble stone in your shoe, it was hard to live with, but bearable. I 'just' need to turn on/off airplane mode every so often and then wifi is back on. Still it is a horrific relationship, so I want a divorce.

Searching for, and applying solutions over the past two years haven't come up with any results. This apart from that your last name needs to be Einstein if you are going through these tutorials to try to solve the issue. Last night I woke up with this miraculous idea (Einstein indeed isn't my last name): An USB wifi adapter should bypass this whole issue!

So, what are your thoughts before I enter the operating theatre: Could this kind of device bypass both my issue AND the original Qualcomm Atheros QCA9377 adapter? If yes, could you girls and boys recommend me (1) what to purchase exactly, (2) should I disable the QCA9377 then in Ubuntu and if yes, how? (3) Anything else I haven't overlooked?

my system details: Acer Aspire 3 A315-54-52UL, with Wireless Network Adapter: Qualcomm Atheros QCA9377 802.11ac, dual boot Windows 10 and Ubuntu 20.04

If this works, this would help out not only me, but all the other blister sufferers out there!

so: thanks in advance!

can you post the result here in thread wrap with code for the result of this command below.

Code:

nmcli general

Code:

nmcli dev wifi list

Code:

nmcli dev status

Code:

sudo iwconfig wlp2s0

this could be a lot of commands but it might help to those people here in the community to make it more easy to them to identify the issue of your device.

Can you please run this command below:

Code:

dmesg

Just paste the result here wrap with code. Thanks

Code:

dmesg

not sure what you are looking for, but that results in an amount information comparable with the contents of the Oxford dictionary.

Any thoughts on my bypass solution?

He really wants:

Code:

sudo dmesg | grep -e wlp -e ath

Is your router set to a fixed channel or autoselect? Fixed is strongly preferred.

An USB wifi adapter should bypass this whole issue!

I don't want to see you suffer and it can be handy to have a good usb wifi adapter around anyway:

https://github.com/morrownr/USB-WiFi

That site will give you a LOT of information about usb wifi adapters and it has many links to adapters that work with in-kernel drivers. If you have specific capabilities or price range in mind I can probably help.

Good luck
