Constant signal quality variance

I am not sure why this happens but the signal quality seems to constantly shift between Excellent, good, fair, and poor - I am using wireless for my laptop and also dial in through a VPN for work (but can access the internet without VPN) - not sure if that makes a difference. Does speed, band, or channel have anything to do with this? I am just not sure - any suggestions would be great! Kristen

I have a Linksys WAG300N running firmware 1.01.01 and also see my signal strength constantly changing along with the speed.
Sometimes the speed will drop right down to 1Mbps but if I disable and then enable the wireless on my laptop it will reconnect back at 54Mbps.
I tried different channels and changing network mode to be disabled rather than mixed as I don't have any N devices. Beacon interval, fragmentation and RTS thresholds have all been reduced. None of this seems to make any difference.
I previously had a Netgear wifi router installed in the same location without seeing these sorts of problems.
I see equal or stronger signal strength from several over wifi networks. It's possible that one of these could be installed in a nearby room next door but not all.

Constant Terrible Quality, Jumping Sound, And Poor...

Hey.
No matter what I try, I get constant bad quality using my BT Vision box. When I play the BBC iPlayer, all i get is crackling and a lot of compression on the noise. Most other channels just give me jumping, crackling and badly pixelated images.
Nothing I have done has improved it. My signal quality is good, and the strength is above 70% for almost every channel. It feels like it is a hardware problem. I have tried the box in 2 locations, and the same result in both places (I moved home).
I was thinking, the fact that even using the iPlayer, and it is still giving me bad quality shows that it's preforming poorly. In essence, its just streaming or downloading the programe from the internet, but it still plays as if I'm using the normal channels with very bad quality...
I hope someone can help because I'm very frustrated with it and very disapointed.
DM

Have you tried calling the helpline? If it shows the same problems with both on-demand and Freeview, then it could be a faulty box.

Signal Quality issues - totally stumped

My first post so apologies if I step on anyones toes.
I've had a browse through and can't find an existing post that covers my scenario.
For a while now my box has been having issues on certain channels. The exact scenario is that the signal quality drops to below 25% which causes picture blocking / freezing.
Before anyone says its a MUX issue, I have tried.
1) New cables
2) Rebooting
3) Factory reset
4) A known good cheapie freeview receiver from Asda shows a static 95% quality on the channels where the BT Vision box has problems. With both the old and the new cables. No signal bouncing - stays solidly at 95% (or thereabouts)
The specific channels it has issues with are Channel 21 (VIVA),Channel 38 (quest +1). I am on Waltham transmitter and other channels on the MUXes have 85% quality and higher on the BT Vision box. On VIVA and Quest +1 the quality bounces all over the place between less than 25% upto 87%.
If it was all channels on the MUX then I'd know it was time for aerial reposition, but with it being on only specific channels and a cheapie receiver working perfectly I'm a bit stumped??
Additionally, since the new firmware, I use a 4:3 TV through SCART and the screen real estate now seems wrong as it chops the bottom off the screen when in the new menu system - so things telling me what to press are lost - ie: to delete a recording from the recordings section I can't see any advice at the bottom of the screen as was there on the old firmware, I basically found it was the red button by trial and error. I'm guessing BT think we all have HDMI TV's and maybe the menu works OK on HDMI.
Its as though the tuner has just decided it doesn't like channels 21 and 38 - maybe its telling me to to watch some better quality programs... Or more seriously, maybe its cooked and has a specific frequency reception issue? Unlikely but I can't think what else it could be.
If anyone can advise I'd appreciate some guidance as I've pretty much exhausted my limited knowledge of TV transmitter behaviour.

Hi Pete65,
It could be possible that if you are in the Northampton/Milton Keys/ Bedford/ etc areas, that particular mux could have some signal interference .
There was a post earlier which I can't find right now, where the author talks about signal quality vs signal strength.
It could also be possible that the signal is too strong which could cause a detrimental effect on the quality.

5.0.1 constant signal drop after every 2 minutes

As soon as I updated the software in 4s to 5.0.1 the neverending trouble started. There are constant signal drop resulting communication lost and despite the signal bar showing full strength. can any one help, Have already triesd the SIM PIN option can any one help? would really appreciate it

mAN?
with that type of config. you have? you should not have any problems.
especially with the intervideo program 'cause it captures in mpg and it is a very loose coding (better said no coding at all)
try turning the ht off through bios
or try this prog.

also did you have xp sp2 allways?
maybe sp2 is causing problems
also
did you try recording on both (4) of your hdd's?

How to Enable Signal Quality (%)

Good Day,
Checked the manuals and forum to no avail.
My Cisco 1200 AP is displaying Signal Strength (dBm) but not Signal Quality (%).
Is there something I need to do to enable this, or is it client specific? Thanks for the help!

the command show dot11 ass all will display the parameter for signal quality

Youview Signal/Quality Issues

I have had a Youview box for a few weeks now and ever since it arrived the signal and picture quality has been very unreliable and patchy, with pixelation, horizontal lines appearing across the screen and breakup in sound when viewing live TV and recordings. I have re-tuned all the channels several times, signal strength is constantly 80% and above, signal quality is 100% and i have tried several different aerial cables and this problem still persists.
If anyone has any ideas then they would be weclome. This seems to be for most channels but im noticing it most on BBC1, BBC2, ITV and their HD versions.
Thanks.

Thanks for the responses all, my BBC 1 is showing as BBC1 East E which would make sense as im in the north norwich area.
I managed to convince my girlfriend to ditch sky for Youview with BT and so far all i have had is complaints that it was a mistake, so im really hoping that I can find a solution to this to make it all go away
Im on ITV HD at the moment and seems ok, the occasional spasm but not as bad as the BBC channels.

Signal quality question

So, this morning when I came into work, the flourescent lights were off (I always like that), and my iPhone had 4 bars of signal quality sitting in a spot on my desk and was on the edge network...
An hour later, I came back, and my phone had 1 bar of signal, and no edge network. What was different? The ligths were on...
Can flourescent lights interfere with signal quality? Of course I know there is all kinds of 60Hz EMI that is going on...and as much as I would like to flip the lights on and off all day to test this theory, I don't think my collegues would appreciate it.

I too have been having VERY strange signal quality issues.
I can be sitting in a chair in my house getting full signal
strength and surfing the web when all of a sudden the signal
goes to one bar. On some occasions I will loose my Edge indicator (the E) and an error message will pop up saying I lost Edge data. This has happened plenty of times while just sitting still. I was thinking that this behavior had to do with the cell site I was in at the time, but perhaps there is more to this. Anyone else have this strange issue?

Original iPhone Upgrade to 2.0 - Significantly Reduced Signal Quality

I upgraded my 1st gen iPhone with the official 2.0 update through iTunes on Friday night. Since then, I've noticed that my phone refuses to keep a steady signal. It happens especially when I'm actually trying to use it, such as when surfing the web or talking on the phone. Even at idle, though, I can unlock the phone and watch myself drop from 4 or 5 bars down to 1 or none. The top half of the phone (where I assume the processor is at) also gets ridiculously hot after only a few minutes use. As a result of this, my battery drain has increased significantly.
I took one poster's suggestion and turned off Push data retrieval, but that didn't see to fix anything yet.
Has anyone else experienced this? This phone used to be very reliable in terms of signal quality, as I'm in the NY/NJ area, so coverage isn't a problem.

Problem solved.
Solution: Create multiple calendars in iCal. Synch will iPhone.
Result: Default calendar settings created in iPhone. Application has multiple calendars.

Texas / Oklahoma Panhandle Signal Quality

Signal quality out here is not what it used to be.
We don't have 4G, but the 3G data speeds used to be adequate for basic email/web browsing and simple apps. Text messages must be resent about 90% of the time, and voice quality is also horrible now. Every other word seems to get lost in a conversation. This is probably the most frustrating.
I have been told that a local telephone company trying to test out their 4g network and not knowing what they are doing is partially to blame. I'm not sure how accurate that is. Maybe Verizon could look into this? If so, talk to the FCC?
I have been keeping my fingers crossed that Verizon was tinkering with the towers in order to upgrade them to 4G, but that's just the optimist in me. I have no idea where to better submit a trouble ticket. I am told calling in to complain will get a routine script.. so maybe this post will get some attention... Can someone can look into the signal quality out here???

I submitted a complaint on Verizon's FB page and they were very responsive, although the canned answer wasn't really what I was hoping for. They recommended a signal booster for phone reception, which requires home Internet service and has nothing to do with data. They also recommend I check this page frequently - http://bit.ly/xVecuo
That is completely useless since it only says whether or not an area has 4G, not whether it is coming to an area. I will know by the data service I receive on my phone when we have 4G. It was worth a shot and I'm letting it go now that I've had my two cents.

AP signal quality reporting

Hi,
When we do a show assoc etc on a 1232 AP,
we get figures back showing signal strength in the region of 70 and signal quality around 35.
What is the reference for these figures?
Is it 70 as in 0 bad 100 good, or is it 70db, where 60 is a stronger signal than 70.
And how does the 35 get measured.
Any help much appreciated.
Thanks

Not necessarily, Signal quality is usually some sort of useless percentage of what, nobody at Cisco can answer. SNR on the other hand is Signal to Noise ratio. This is a quantifiable number that refers to where your signal is in reference to where the noise is. SNR is measured in dB as well. If your noise is -88dBm and you signal is -65dBm, then your SNR is -23dB (which is good depending on what your doing with it, voice would probably work depending on whose it is etc...)the lower the number the SNR is the closer your signal is to the noise. Think of your car driving around until the radio station starts to drop off. If it's a really good song you will put up with the static so long as it isn't unbearable. When it becomes unbearable you will find something else to listen to.
Think of -25 to -30 as very good (depending again on environment etc..just a guide not a rule), -18 to -20 ok, (VoIP might be giving you problems but your data probably still works) and anything lower than that is pushing it.
This is not to say that signal quality is useless altogether, it must be looked at in conjunction with signal strength and SNR and the environment it is in etc... in order to give you a picture of what you have or what you think you have anyway...

Sinus signal quality

Hello!
What is the best way to define quality of sinus signal?
Regards!

I'm not completely sure what you are trying to find. Two common measures of signal "quality" are signal-to-noise ratio (SNR) and total harmonic distortion (THD).

Signal Quality - Signal to Noise. But not in webinterface?

After upgrade from 12.2(13)JA4 to 12.3(8)JA2 on our 1230B AP's we noticed that clients Signal Quality (%) is changed to Signal to Noise in the CLI, but not in the webinterface. It still says Signal Quality (%), and a blank cell .
CLI: show dot11 associations all-client
Webpage: AP-IP/ap_stationview-client.shtml

The antenna opening for the iMac is on the back of the screen, so make sure that the iMac is not pushed back into a cabinet or even a corner of the room. Sometimes a small change in location will make a big difference in reception.
Also check to make sure that you do not have other electronics near the iMac like a cordless phone, ampliifer, satellite receiver, TV, etc.
If the iMac is near a window, it may be picking up wireless interference from another network in the neighborhood near you. Try to move the iMac away from the window to a different location.
Power off the iMac and restart after any change in location so that it will establish a new connection.
If you try everthing and the results seem to be the same, then you might want to think about taking the iMac to an Apple store in your area to let them have a look and check out the wireless card in the device.

Razr M Signal Quality Poor - Voice & Data

My Razr M is only days old. I switched from T-Mobile because of dropped calls and weak signals around the metro Atlanta area.
This new verizon phone has a very week signal in my home, and Verizon's map show's I'm in a "green zone" on their map. In other words,
I should have plenty of signal strength and 4G LTE service without difficulty. The phone displays 1 to 3 bars flutuating, but usually at 1 bar.
Signal strenth fluctuates between -97db to -107. Data rate between 1x & 3g with or without accessing my wireless router. I called Verizon
and they asked me to call them from another phone. I understand the troubleshooting technique, but I unless my wife is home.... you get the picture.
She has the identical phone. I managed to compare the signal strength this morning, and they're identical. My phone has locked up twice during recharge, but may be the charger. I had to reboot the device to power on afterwards. I suppose the true test of this phone will be while we're on the road this weekend.
Otherwise, the quality or clairty of the call is great. The phone itself is light years better than the "Lg MyTouch" in quality. I hope to be a loyal Verizon customer, but not quite sure yet. Anyone else have comments on their Razr M ?
Thanks,
Jerry

Not to ruin your upcoming trip. If there are problems now after a few days with the phone I would suggest you go back to the store (Verizon Corporate Store) and return them before you reach the 14th. day of ownership.
My wifes Motorola Droid works perfectly never had any problems with this model. I cannot say with the M but they are like phones.
If you wait till day fifteen you will be getting a so called Certified Like New Replacement (refurbished junk that had problems which may be greater than what you now have) and the issue you are writing about may still be there.
If you return your phone they will charge you a $35 restocking fee. But you could either swap it out for the same phone brand new or even try out another make and model to see if your problems are fixed or still the same.
Do this now because you will not like dealing with verizon for your repairs or lack of it. There are other nightmares when you have to send your device back. so be very careful.
Good Luck

Wireless signal quality just randomly worsened.

Well.. its good day from TK31 and his dodgy macbook pro. I've been having a lot of problems recently with this macbook, and this is yet another chapter in the suffering.
Okay, the wireless quality suddenly decides to stop having reception in my room. It shows full connection quality, but it cant seem to connect to the ISP, Internet, Server.
My room is upstairs in a normal house, around say 2-3 meters (6.5 - 9.8 feet) in a North Westerly direction from my antenna. not very far. As soon as I walk into the corridor, around 1.2 meters closer to the router, i get internet connection back. like IMMEDIATELY as i step out of my room... not an inch further out, not an inch closer inside the door.
The only thing separating the router and my macbook is the 2nd floor's floor.
Also, even though it displays full connection quality in the airport settings, i cannot access my router's settings page, which when pinged returns timeouts.

Thanks. that was close to the solution. I reset it, but moved it away from an electronic water filtration system i have going in the house. It either was interference from the filtration system, or as you said, a simple repower as i've had the router on without switching it off for around a month now.
