#198456 — which program/command can show wireless connection quality?

[Multipart message — attachments visible in raw view] — view raw

i have a USB wireless card, it doesn't seem stable, sometimes it's slow
i even suspect changing USB connector can affect network speed

which program can show connection quality?
i use twm, those that depend on big software (KDE/GNOME) are not preferred

Try wavemon! I used to use it on a laptop without graphics installed.... it requires ncurses but who doesn't love ncurses?

 Thanks!

i've just installed wavemon, it shows too many details, i've not been able to figure out all their meaning

These two should work with any network interface (watch for error and
dropped frames):

netstat -ni 1

watch -n1 "ip -s a l"

Wireless specifics (signal strength, noise ratio, etc) are better viewed
by airodump-ng from aircrack-ng package, although stock iw or iwconfig
should do too.

Also, consider wrapping a sheet of tin foil around USB WiFi dongle,
transforming stock omni-directional antenna to uni-directional.

Uni-directional or no-directional?

I'd have thought you want to be fairly specific and precise with your
'wrapping' to get a benefit ...

 Thanks! 

my adapter is Asus WL-167g USB WLAN Adapter
i don't understand why change directional from omni to uni

the adapter is problematic, sometimes it works fine, other times it doesn't though link quality is good

maybe buying a new one is more cost-efficient than debugging the old one

Because if it's the noise/signal ratio that's the trouble this should
improve it.

Or, it's your neighbour's APs which give you signal interference. Or a
nearby police car (radar).

This surely falls under the signal noise category, but it might not be
something people ever think about. It's power lines. My yard is
wrapped in utility lines k/t how it sits in the Universe. Both MATS
(local transport, Mountain Area Transportation System) and local
Pickens County Sheriff's Office during 9-1-1 emergency calls are NOT
able to call out *at all* when they're sitting in my driveway.

Seems natural to a-sume those two community resources have
communications systems powerful enough to worm through anything, but
apparently... nope. At least not when it comes to sitting underneath a
tight nest of power lines. :)

 it has nothing to do with police or other AP

i have a PCI wireless card, it works fine, i needn't monitor its performance with wavemon

the USB adapter works in the same environment as the PCI card, i really don't know cause of its problem

if you run them in parallel (simultaneously) you will have the problem

Google it. [2] uses a strainer, not a tinfoil, but is pretty close to
what I meant.

Sure. I just meant that naively 'wrapping it in foil' is unlikely to get
the desired result.
