Those labels aren't terribly meaningful -- I've seen devices that report
"very" or even "excellent" with so much interference that the connection
cannot be maintained. You need to look at real signal strength and
noise numbers.

As you wrote it, no.

Signal and interference problems are indeed possible, AS I SUGGESTED WAY
BACK AT THE BEGINNING. (Sorry for shouting, but you're making this way
harder than it needs to be.)

Why doesn't make it sense? I asked some people and this could be
possible. Signal quality and strength are not the same. Although
signal strength ''very good'' or ''good'', wireless may drop. But when
it is ''excellent'' wireless is stable. So it makes sense.

Additionaly, i closed 2 doors covering wall between adapter and
router, wi-fi drop solved. Signal interference is not the reason, i
tried with many channels as suggested.

Buying a 5dbi antenna improves signalling quality/noise reduction?

I have a standard 2dbi antenna.

Thank you.

Because what you wrote (e.g., "brackets", "spreading") literally doesn't
make sense.

>I asked some people and this could be

What could? Brackets? What kind of brackets? Plastic or metal?

Actually it doesn't. There can be problems even with "excellent" signal
strength. The usual issue, again, is radio frequency INTERFERENCE.

>Additionaly, i closed 2 doors covering wall


"Covering"? How do they do that? You mean doors _in_ those walls?

>between adapter and
>router, wi-fi drop solved.


Makes no sense. You've got some other issue.

>Signal interference is not the reason, i
>tried with many channels as suggested.


In fact you may have reduced interference by closing those doors. Can't
really say because you've provided so little information and paraphrased
so much I can't understand what you are trying to say, much less what's
actually happening.

>Buying a 5dbi antenna improves signalling quality/noise reduction?


Depends:
* A higher-gain _omni_ antenna may well amplify noise as much as signal.
* A higher-gain _directional_ antenna is more likely to _reduce_ noise
while increasing signal, thus increasing the all important
signal-to-noise ratio.

>I have a standard 2dbi antenna.


If you're lucky -- many aren't even that good.

OK, there are 2 wood doors and a wall between router and adapter.
After closing those doors, only the wall remains and connection
becomes at ''excellent'' or ''very good'' level with no freeze.

But if i block or open doors near router, an instant signal
decreasement can drop wireless as i determined.

I mean doors made by wood, there are some glasses inside frames.

I agree with you. The signal strength is not reliable.

Closing door helped but i'm not sure because the testing is not over.

What do you mean by saying ''other issue''?

There are no such info i can give, because it is a home planning of
devices positions.

I am asking for swivel antenna, can be found here which i'm thinking
to buy with no hope for indoor use with walls and doors:

Yes, 2dbi is not so good but if there are no blockages like doors and
walls, it's enough as you know generally.

Best regards, too.

Hi John,
I still have strange freezes about wireless. But the only thing i
found out is: Wi-fi speed decreases to 24mbps or 18mbps when freeze
happens. With the minutes working on 54mbps speed, it's stable.

So can we call it's about signalling? I had this freeze now even doors
are closed which were covering around router, and i reduced blockages
between router and adapter.

Also higher SNR is better?

Thank you.

Sounds like radio frequency interference. See possible sources in wikis
below.

Correct.

I checked all Wikis out. But which type of interference can occurs
although i'm on different channel than the others'? (looked at site
monitor for channel usage around me)

Many (most?) types of radio frequency interference aren't limited to a
given channel. For example, many cordless phones hop all over the band,
trashing all channels.

Hi Mr. Navas,
I want to update: Today, although speed was 54mbps and signal strength
was "excellent" and SNR is very good (-45dbi signal, -90dbi noise), wi-
fi froze again and there wasn't any networks on my channel other than
me visually. Also i may have this issue when internet is
"idle" (minutes which are not in use but connected)

So, what is your conclusion?

Regards...

That you've given us no real idea what "froze" means.

Hi, Mr Navas,
If you read some previous messages of me,i've explained numerous times
about "freeze", i call it "freeze" or you can call it different.
I'm repeating the problem:
-For some reasons-, while i'm on wi-fi connection, sometimes, the
wireless data transfer stops, even i cannot reach to my router, but wi-
fi connection icon says "i'm still connected", but i'm dropped from wi-
fi AP router. Wireless data connection stops, it dies,
the taskbar wi-fi icon stops flashing as a result of freeze or i can
call this problem ''unresponsive or non-reaction wireless
connection''
although it still seems connected. (Duration counter of wi-fi icon
continues) . NOTE: I'm not mentioning about computer freeze, no
Windows freeze. Or no virus(checked)

But when i have this freeze or you can call "drop", i can connect the
net over wired connections without touching the modem or computer.
Then after wi-fi freeze or drop is experienced, i looked at wi-fi
client list of my router, i saw my adapter is not listed in there
anylonger!. That means my wi-fi connection has dropped although
taskbar icon or other wi-fi programs says i'm still connected.

I tried 1,6,11 channels with no luck. This happened when i'm on a
different channel than the other neighbour's networks. That happened
when i wi-fi speed was decreasing and i'm seperated from my router by
a wall and 2 doors in the same house.

Then i moved computer to the same room with the router, now the signal
strength is usually "excellent" but that problem happens very rarely.
If you scan the messages of this topic shortly, you can remember my
issue.

Additionaly, clicking "repair" button of wireless netwok connection or
"disabling the re-enabling" the adapter, helps to resolve that
problem.

I uploaded screenshots for in order to give you some idea about SNR or
signalling or noise:

Those screenshots describe a stable and non-problematic wi-fi
connection which runs very nice:

Those screenshots are taken when w-fi "drop" or "data transfer freeze"
occured:

The last screenshot describes the report of Windows regarding my wi-fi
connection although i'm dropped from wi-fi:

I tried to explain as much as possible i could.

Thanks again.

Hi. Try resetting your router and starting over, leaving DHCP on.
Set your wireless adapter to get addresses and DNS automatically. Set
your DNS in the reouter setup page instead of the client?


Run it with WPA off for a while. See if it works. Turn WPA back on
and see if it works.

Is working with WPA-PSK( a 22 digit-key) a problem for wireless?

It shouldn't be.

I want to update the latest situation:
First, i want to name the problem: It's a wi-fi "drop" occurs between
adapter and router occasionaly.

After working well couple of days, wi-fi drops although it seemed
"connected" in XP's system tray with no notification of disconnection
but i can realize "drop" by looking router's client list.

But the question is: Why does drop occur although router's/adapter's
positions and distance are the "same" when like operating in a stable
enviroment?

I can operate stable for a long time/days/weeks, but one day; wi-fi
drops though there's no placement or setting change for router and
adapter also.

So, can we say: The drop is caused by "external" factors like signal
interferes and noises?

Possible interference.
Possible problem with DHCP lease renewal.

Possibly.

Hi Mr. Navas and thanks for the reply,
I have to know this also: What are the stability thresholds of Wi-fi's
"signal levels" and "noise levels"?

For example, when signal is worse than -60 or -65dbi, i get drops,
when it goes around between -40 and -50dbi it's much more stable with
no drops.

Is there a tested or accepted threshold value for signal and noise
level to have a maintained Wi-fi operation?
