Unstable fibre-op wireless connection

Frank Geitzler
I have a HP/Compaq Presario CQ61 Notebook about six years old, and have
had Bell-Aliant fibre-op for about a year.  Over the past several weeks,
my wireless connection has been very 'shaky'.

I may be in the midst of writing an email, when suddenly the Wi-Fi
Network Authentication Required pop-up will appear, informing me that I
have lost my connection.  As if that were not bad enough, the password
line has focus, and as I type about 60 words a minute,   the chances are
good that I may type over the wireless password -a 16-character
hexadecimal string.  I then have to look that up and re-enter it.  There
is usually no problem re-establishing a connection, but it may only stay
up a few seconds -or for hours.

Could the adapter be failing?  Is there a log in Ubuntu which might give
a clue to this?  I was able to obtain the following information, so far
-any assistance would be appreciated.

Thanks,

Frank

Hi Frank,

Possibly:
sudo dmesg |grep theros -A 2 -B 2
...to retrieve output of log matching Atheros/atheros, five lines (two lines before and after) at a time.

Do you have a way to check the status of upstream devices, such as a system with an Ethernet connection to the wireless router, status lights on the router, etc.  If you are in a high density area and have a smartphone you might want to get one of the "free with ads" wifi scanner to see if anything odd is going on.  Having said that, wifi and Ethernet adapters do sometimes fail in service.  Back in the days when Ethernet adapters were common, I had system that seemed to connect to the network OK but NFS was failing.  When I looked at the adapter there were some carbonized components.  A new card got NFS going.  I assume the failure had increased the rate of bad packets, so UDP was useless but TCPIP could still work.

Older distress used "netstat -i ..."; but now there is "ip" to see some stats for
a specific interface.
