[closed - unresolved] Cannot make a wifi connection

I can make an ethernet connection on my two laptops, but I cannot connect via wifi. My problem is identical on each laptop.

When I click on the connection icon on my toolbar, the networking window pops up and my router shows up as normal. If I select my router and click on it, the window indicates that a connection has been made. But when I ping the router address (192.168.1.1), the ping fails. This has never happened in the past, and I am not sure how to fix this problem.

Can someone walk me through the problem or point me to a write up?

Re: [closed - unresolved] Cannot make a wifi connection

Have you tried a connection after cold restart? (Shutdown-wait-start)

If that doesn't work try posting the results of

inxi -Fxxz

(or similar)

>>> Have you tried a connection after cold restart? (Shutdown-wait-start)

I did the cold start with no change in the results.


I ran "inxi -fxxz" and got the following results:

Re: [closed - unresolved] Cannot make a wifi connection

From Guide to getting help "Terminal tools like "inxi -Fxrzm"".
Flags -"Fxrzm" gives a lot of information.
Flags -M / --machine, -n / --network-advanced, -xx / --extra 2, and -z / --filter (filter out sensitive data) is enough.

According to the hardware database https://linux-hardware.org/?view=comput … spire+5253 can the wifi chip vary, Some of the chips has problems.

Re: [closed - unresolved] Cannot make a wifi connection

I guess there is a good chance the chip is not supported. I am going to close this issue out as unresolved.

For the record, the wifi chip is: Qualcomm Atheros AR9287 Wireless Network Adapter

Re: [closed - unresolved] Cannot make a wifi connection

You could try websearching 'debian AR9287'.

There are a lot of hits, might be some help somewhere...

According to linux-hardware.org, your chip is supported from kernel 2.6.32: https://linux-hardware.org/index.php?id … -11ad-6603.
It is easier to search the database on linux-hardware.org, if you find the Vendor ID:Device ID. If you in terminal, give command

lspci -nn

the result will be among other info: "[168c:002e]".
Flags -nn, returns both vendor/device name and code.

So, proably you have a working linux driver loaded for the chip.

Command

inxi -nz

will list the driver after the device-name.

Maybe it is so simple that your chip has been blocked?

Check with command

rfkill list
