Sporadic Loss of Signal

Every so often the signal from my WRT54G will be so that wireless devices lose connection. I've tried changing channels but I live in an area saturated with wireless routers so I'm not sure how much it helps. 99% of the time the router is fine and reaches all parts of the house with any problem so I know there's no issue with distance or obstrution. Sometimes I'll restart the cable modem and the router and that seems to help, maybe, but it's hard to tell. Any other ideas to troubleshoot? I wish I had a personal spectrum analyzer...

If you have to power cycle the Modem and the Router both in order to get the connection back it may be possible that your modem is disconnecting you from Internet...Connect your computer straight to the modem and check if you face the same problem...If you get stable/constant connection then you need to upgrade the router's firmware...Download the firmware from here ,
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router and check if you get a stable connection...

Using keynote presentation on projector have had brief loss of signal

I have changed projector and iPad and still experience during keynote presentation a brief loss of signal to projector.
This happens at random and keynote presentation restarts on projector. Tried every source to help and followed all advice and it still
happens at random. Can play a movie using same gear no problem at all; Please Help.

Please do not type in all caps, that is considered shouting on a public forum and also rude which I am sure is not your intent. I would also suggest reposting in the Keynot forum, that is where the Keynote gurus are likely to be.
Good luck.

IPhone Death Grip and Loss of Signal

There is NO doubt the new iPhone has "death grip" "loss of signal" issues. Including my new iPhone, there are 4 Verizon phones in my home. All 4 phones show 3 bars when laying on the counter. The iPhone consistently, everytime, drops to 1 bar when it is picked up and held in a normal position. The other 3 phones (HTC Incredible, Blackberry Curve 8330, and an LG Cosmos all maintain 3 bars when picked up and held in a normal position. In fact, when I recived my first call on my iPhone the caller complained my voice was breaking up. NONE of my other phones have that problem. I called Verizon support on my iPhone, and they said my call was breaking up. I changed my holding position so I was pinching the the front and back of the phone (not touching any of the metal frame), and they said they could hear me much better. Nice test, huh? I have checked this situation over and over. I am not going to "pinch" my phone to use it. I am not going to spend more money on a bumper or case to use it. I am going to hold Verizon to their promise that that the known antenna issue with the iPhone was fixed. I am going to return my iPhone for a full refund and HIGHLY recommend that ANYONE who thinks the antenna issue is fixed is flat out WRONG. I HAD a lot of confidence in Verizon and Apple before this fiasco. There is NO DOUBT in my mind that both of them new full well that the defect still existed and still hyped and released a defective product. I will be the first to gladly participate in any class action suit that comes out of this - which I am sure it will. DO NOT BUY AN IPHONE 4.

Verizon didn't promise you that the issue no longer existed (if a rep that hadn't had a chance themselves to see the phone until activating them for customers on the 10th told you this they were not the most reliable to respond unfortunately). Technically I don't recall Apple ever officially stating so (they never said they did the antenna changes as a "fix" to the issue...they said they did it to accomodate the CDMA chip), but if they did and it does not happen to be true for you and the phones in your household then by all means return them. At the end of the day, Verizon did not make the equipment....they just finally worked it out to get the rights to sell it with their service for the customers that have been begging for it for years. Be disappointed in Apple (as far as the antenna issue goes). For you, the issue exists. For others, it exists. For many, it does not. So being able to say there is NO doubt that the issue still exists is still very debatable at this point. Personally, I have had almost 1 full week (tomorrow) of crystal clear calls, no antenna issues, no dropped calls or dropped bars other than the normal that occurs with any phone on any network. Actually, the bars on my iPhone are interestingly more stable than those of my Blackberry Tour were.
At any rate, I'm sorry that the iPhone did not live up to your expectations, but your experience is not definitive of all iPhone users any more than mine is.

Loss of signal

Over the past week I keep loosing my signal and it changes to "emergency calls only". I contacted vodafone who checked and advised that there was not a server issue then I visited the shop who gave me a new sim card, any advice on what the problem can be, also battery now drains within 24 hours, never used to be a problem?
Thanks

If you are traveling or moving about you may be experiencing a loss of signal strength which can cause what you describe. 24 hours on a Z10 is incredible battery life. I use mine a lot and find that about 8-10 hours is the max I can go without switching out the battery or without charging.
There also may be a sim card issue. Try swapping it out and see if that makes a difference.

HT4061 IPhone 4s Unexpected loss of signal

Is there a Way I can contact someone at APPLE or somewhere else so I can solve my software problem with my IPhone 4S?
Unexpected loss of signal and communications have occurred to the point that I cannot use my phone any longer. I went to see my telephone service provider and they told me that there is no problem with it (service, signal, chip, etc.) but they have been aproached by many IPHONE 4S users reporting the same problem.
I have read many things about this matter in internet but no one seem to have solution to this. Everyone (around the world) agrees that this is caused by a faulty software. I have updated my phone with the latest version (OS 6) and the problem has gotten worse. I also have battery problems since this one doesn't last not even 3 hours after the upgrading. I have found NO other place or option where I can get support but this "Apple suport communities". I bought my phone,factory unlocked, from Apple Store in NY and actually I'm using it in La Paz, Bolivia (South America).
I belive that if Mr. Jobs would still be alive things would have been different.

I have the same problem with my 4s work ok for 1 week when I got it and now it keeps losing signal fix this apple please it's not my mobile provider everything is ok on there side.

Repeat loss of signal

I have a WRT54G ver.6 and i am able to connect to the internet but loss the signal randomly every few hours. Upgraded Firmware with no luck. Somebody please help

I had this same problem - lots of us apparently do. I read numerous threads, tried numerous changes to settings, upgrading the firmware, etc. I even tried a newer version of the router (WRT54G to WRT54GS). Nothing worked. I then tried changing to the DD-WRT firmware, and since then, I've had zero problems: no dropped connection, no rebooting the router.
Visit http://www.dd-wrt.com/wiki/index.php/Main_Page for info on the firmware and instructions on how to download and install.

Loss of signal aftrer 15 minutes with no use

how do I cahnge settings to allow audio file sto continue without interuption?

Interesting. I suspected something like that would happen. It's the way the iPhone 4 is "talking" to the cell towers. Perhaps in Buffalo you have much lower cell signal strength than is advertised by the bars, therefore any interference by hands will make it drop. And in Canadia, you're experiencing much stronger signal strength, therefore your hands don't even impact it all that much.
I have NO signal loss, bar drop, data speed drop, etc here in Los Angeles, Specially in my neighborhood. I know i must has a cell tower nearby, since i've never dropped a call or seen my bars drop below 5 bars for years and years now (3 years on orginal iPhone and 2 years on Cingular).
So i do suspect that it's an issue with how the bars are displaying signal strength and not so much hardware. Although, it could be both. But in my experiences so far, i have no issues what so ever.
Good test. Glad you reported this. Could shed some more light and help others

HT1267 I have a factory unlocked Iphone 4S, it worked fine but it was lossing the signal and going into search, I decided to restore, but now can not activate it, a message can not be activated because the server is temporary unavailable try again later??

I have a factory unlocked Iphone 4S, it worked fine but it was often lossing signal and going into search, I decided to restore, but now can not activate it, a message can not be activated because the server is temporary unavailable try again later, I have tried this for 3 days, any suggestions?

yes did you buy it of somebody or a well known company such as apple or carphone warehouse?
and i mean the phone would have been activated in the first place with the sim card you get given when you first get the phone.
trying to activate the phone with another sim card that you did not get when you brought the phone may result in you not being able to activate it
no worries

Nokia N97 loss of signal.

Hi to all!
Let's get straight to the point. So, my Nokia N97 lost its signal! i restarted the phone and everything. What should I do?

Contact your service provider, you may have a sim card problem, I had a new sim sent a couple of months ago as mine was about 5yrs old and they are improving as time goes by, unless you dropped your phone or something, it's unlikely that the phone would just 'stop' receiving a signal !

Loss of signal after reboot

I am losing my iPhone's signal everytime it is rebooted, for example when it runs out of battery. Then, after boot up and after entering my PIN code, it keeps saying "no signal" and the only solution is to do a reset by pressing home+power buttons at same time.
Can this problem be solved?
P.S.: I've recently travelled to another country and used roaming.
I've already done a reset to my network settings.
Thank you all!

Yes, alternate universe appears to be the most logical explanation. After months of no signal at all on the iMac, but great signal on the four other wireless connections, suddenly with no other changes or adjustments, simply doing a QuickTime update, causes the signal to re-appear during the update, to remain during multple reboots - even after rebooting in OS 9.2.2, and then rebooting again in OSX.4.6 the signal is still great - and even after five days the signal is still great - no signal fluctuating over the past five days (that had been a common phenomena before) - no signal drop offs during the past 5 days (that also had been a common phenomena). What? was it one of those wild coincidences, that at the precise moment that I was doing the QuickTime update, that actually an hideous, undetected RF Interference source chose that exact instant to stop interferring and to remain non-interferring until this present moment (doubtful) - or was it somehow related to software or to the update process? (I realize that this is not an attractive hypothesis, but is it remotely possible? - Of course, if it is in someway, that Apple wouldn't come out and say as much - not prudent -, but would attempt to correct it in a subsequent update)
---- So Gino, re-enter the real universe, don't speak these things, but be quiet and simply be satisfied that you have a good signal again - you'd be better off not even remembering that these other things even happened.

Loss of signal with iphone4

Anyone having an issue with the iphone4 losing the signal? I'm in town and usually get a full signal strength but at numerous times it will lose all bars and wont connect without me having to power it down and then turning it back on.?????

Since powering the device off and on resolves the signal issues outlined on your post, I would recommend to use the Restore function for your device as a first step to resolve this issue. Using the Restore function for your device will bring your phone to original factory condition and will resolve any possible settings conflicts with the network.

Loss of Signal when in sleep mode

I have an iphone 3g and the problem I am having is the phone when put into sleep mode sometimes doesn't receive messages or calls. When I go to unlock the phone it is sluggish to unlock and then can take up to 15 or 20 seconds acquire signal. At that time I receive all the texts and voice mails of people that missed there calls while the phone was asleep.
Apple has replaced my phone, I have done a restore from back up and set up as new. I have kept off music and apps. It does it in edge or 3g.
HELP!!!!! Apple says no one else is having this problem but I cant believe that.

I have been having the same problem ever since I got my new iMac in December. Been on the phone with tech support about 6 times. I think my problem is related to interference within my house. I have tried everything and just today moved my computer to a room very near the Airport Extreme base station. So far all works perfectly. I didn't have this problem with the linksys router I was using with my PC before getting the Mac (802.11g). I have a 5 GHz wireless phone system in the house and maybe that has something to do with it. My problem only occurs after a "long sleep," so I'll have to check things out tomorrow, but getting the computer near the base station seems to have made a difference.

UTA200-TM Modem Loss of Signal

I recently signed on for tmobile @home VOIP service and been having an intermittant issue where my cable modem looses signal/activity. I worked with my ISP provider and even added a new cable modem (CM100) and found that there is no issue when the computer is directly connected to the modem. Once I connect the adapter and router though the modem locks up and the activity and Cable/online light goes out. I need to reboot several times and disconnect the adapter to get the signal back.
Here is my set-up ( in order).
Linksys CM100 cable modem
Linksys UTA200-TM VOIP adapter
Linksys WRT54G2-V1 wireless router
Router connected to one computer via wireline, and a few lines are in place which are not active at the moment or since I added the adapter. Wireless is off.
Any insight that anyone has to this issue would be appreciated.
Thanks!

Take out the VOIP Adapter out of the equation and see if you have stable Internet Connection through the router and the modem...

Blackberry Z10 loss of signal

Hello,
maybe somebody can help me. Last time I have problem with my Z10. When I talking, my phone loses signal and connection is dropped. I found, when I'm calling the signal is not stable. Before it didnt happened. Today I installed the last update (now I have 10.0.10.690), but it not help.
Sorry for my bad English.

Hi AndreyP80 and welcome to the BlackBerry Support Community Forums!
Typically connectivity issues can be a result of a poor coverage area or a faulty SIM card. Have you contacted yoru wireless provider regarding these possibilities and your dropping signal?
Thanks.
