"No Service" signal strength related

So I got my iPhone and went through the set up on iTunes. I am porting from Verizon so it told me that they are working on my activation. Anyway, My phone says "No Service" up in the signal strength area. I walked around my house and it did not change. Then I got in my car and drove around and it still say's "no service". Does it say this because the phone has not been activated or do I actually have no signal strength? If so will ATT be able to activate my phone?

I'm wondering that myself. I've been an AT&T/Cingular customer for several years, but recently moved to a location where the signal is weak to the point that I often have to go outdoors to make a call. I'm still not activated, but I've been seeing either "No Service" or - occasionally - a sliver of one bar. Even outdoors. Yikes!

Wifi Signal Strength related issue

Hello.
My Hp latop shows only a signal of a bar
or two when placed in the same room as
my wifi router.
It shows a signal of 3-4 bars when placed
very close to wifi router.
Can someone please help with this issue.
This has been a small problem in my home
but now I am moving to a new place and
wifi there is too far from my room. My
laptop doesn't even connect to the internet
over wifi there.

Hi , Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP Pavilion 15-p033tx Notebook and the Wireless connection signal dropping and only giving you a few bars. I would change the Channel on the router. Routers are capable of communicating to your Notebook on several different channels and sometimes this helps. You could turn off IPv6 for the notebook. This has helped others. Fix this problem Microsoft Fix it 50413. Here is a link to help as well. I hope something here helps. Please let me know how this goes. Thanks.

Have just arrived in New Zealand, and have connected to local wi fi network with go signal strength, but phone keeps saying no service? Any idea what to do?

Have just arrived in New Zealand, have connected through local wi fi network, have good signal strength, but phone says no service, cant send texts out! any ideas?

Text messages are sent via the cellular network, not wi-fi. Only iMessages are sent via wi-fi. Unless you have roaming turned on for the phone, or you have an unlocked phone that you installed a local SIM, you would continue to see No Service. That reflects your cellular carrier service. Connecting to wi-fi has no bearing on your cellular service, which is what displays on the status bar of the phone near the signal bars (circles/dots).

My iphone 4 Carrier signal is very weak just shows one bar and often shows No Service followed by searching and again one signal bar I have had a lot of drop calls, I have tested the sim card on my Samsung Ace which shows full Signal strength I am on the latest iphone firmware 5.1.1 with 4.12.01 baseband I have tried resetting the iphone did o full restore twice. I guess there is something wrong with the iphone hardware? Has anyone had similar issues and how they fixed it?

Take the device to Apple or an Apple authorized service center and let them check it out.

Does the Note 4 have better signal strength than the Note 3?

I have a note 3 that continually drops calls and bounces from 4 bars to 1 bar over the course of time with the phone being stationary. I believe my problems started with the last software update (as documented in numerous forums) but both Verizon and Samsung give no credibility to problems raised on internet forums. The people on these forums apparently "lack technical expertise" was my take on their explanation.
So far they, Verizon, is following exactly the same course of action to try to correct my issues as other folks have stated they tried with tech support. Replacement of the SIM card did nothing. Software reflash is next followed by a factory reset with no additional apps allowed to download to the phone.
I have not looked at a Note 4 nor do I know anyone that has one so I am reaching out for information. What is the Note 4 running for software and if you owned a Note 3 previously did you experience signal strength issues where you felt you shouldn't have? If you had, or have, weak signal strength were you able to compare it to another android phone on the same carrier to see if the problem was specific to you phone?
I understand the bars are not the best indication of signal strength but they are a quick indication. Under the mobile networks I usually have -100+ dBm and 30 +asu. If it is a software caused problem neither Verizon or Samsung knows anything about it which is good news because they should be able to correct it. I have my doubts the people on the forums are the crackpots they make them out to be. I suggested they are people like me who are desperate for help with a problem Verizon gave up on.
If the Note 4 is better I know what to ask for when they hit the end of the road with me. That will happen software and reset wise in the next week then I am off to "getting someone else's problem phone" sent to me for a swap. Last time they tried this the junk phone they sent didn't even recognize the sim card!
Thanks for any facts you can provide about your experience with the Note 3 and Note 4 as related to signal strength in both areas with strong and marginal service.

I have an iPhone 6 on Sprint for work and it stinks, I don't like the service or the phone. Had an iPhone 5s prior and although I didn't care for it it was still better than the 6.
I had a software reflash done at Best Buy and a factory reset at Wireless world. Reflash went smooth but I should have done the factory reset myself or had Best Buy do it. It will take me days to get the phone back to where I had it. Kies software from Samsung does backup the phone but you lose all the changes you have made to the Home screens and some other apps need attention to get them functional.
Signal strength remains the same but need to use it for a few days to know if it still drops calls and breaks up. If it does next on the list is running in safe mode for a few days to see if an app is causing it. If the problem still persists I have the choice of replacing it with insurance, money out of my pocket. Sending it to Samsung for testing and repair (if necessary), or having Verizon send a replacement refurbished phone. Probably will go with the refurbished phone and hang on to mine for a few days as well. If the refurb isn't any better I will return it and then send mine to Samsung.
According to Wireless World the insurance company will pay me for my phone if I trade it in before a year is up. May get up to 50% of full retail. Not sure what to trade it in for if I go that route.

Poor signal strength on MacBook Pro

We bought a new AirPort Extreme 802.11n for Christmas. Setup was fairly easy. We have two Macs--an 2005 iMac which is plugged into the AE via Ethernet, and a MacBook Pro from mid-2006 that we use in other rooms.
Our problem is that the signal strength on the MacBook Pro is terrible. Even at just 20 feet away, the signal strength varies between 1 and 3 bars (most often just the one tiny bar). The wireless is basically unusable at that point because pages stop loading.
To eliminate interference as a problem, our daughter brought her 2008 MacBook Pro over and we carried it around the house. It had 4 bar strength with no problems wherever we went and held 4 bars for hours while she used it in the kitchen. So we're pretty sure the problem is not interference in our house, unless her newer AirPort card is far better at blocking it.
What could be causing the signal strength on the older MacBook Pro to be so lousy? The computer is a Intel Core Duo, 2.16 GHz, running 10.4.11. The wireless card is 0x168C, 0x86. The wireless network adapter is 802.11 a/b/g, so it's not running "n", but I can't believe that's the only reason it won't hold a good signal. The AE is set up to run "n" as well as the older ones. (Bear with me...this is my first experience with wireless!)
We've been trying everything we can think of to improve the signal but nothing works. When the bars are in the 2-3 range it runs the internet fine, but the problem is that the signal constantly shifts between 1 and 3. So is the AirPort card in the computer that weak?
Any ideas are most welcome. Thanks.

I'll bet this is a hardware/firmware card with a chunk of AEx cards. I have had the same problem with a recently purchased iMac that was assembled in early '08. I tried all sorts of fixes, but ultimately took it in to a local Apple shop. The "geniuses" spent about 30 seconds looking at the machine (failed to replicate the problem), but then recommended replacing the airport card. I just got it back today &, while I can't yet say everything's hunky-dory, I think the problem's been solved. I'll bet there's a service bulletin that the genius bar has access to that describes this issue.
I had the same AEx series you report. I had the problem with 10.5.4 & then with the 10.5.6 upgrade.
See the following lengthy thread for more similar tales of woe: http://discussions.apple.com/thread.jspa?threadID=1815644&tstart=0.
I think this is hardware-related. It's a $183 dollar fix (parts & labor) -- mine was under warranty, but I think there's enough in the discussion forums to justify pushing for a free replacement, even in an older machine.

What's the connection between data connections (3G/4G/WiFi) and phone signal strength (calls)?

At home I'm almost always on my wifi with the 3G/4G turned off. I've turned it on to experiment, and I get 3G in my house, but the reception (to make and receive phone calls) stays at 0 to 1 bars. There is a Target store about a 10 minute walk from my house and I get 4G LTE when I'm shopping there, but the reception (calls) is still weak, maybe better but I can't tell you offhand.
There is a Verizon tower about 6 miles southwest of my home; they actually had me drive out and sit under it last winter to fix a Droid Pro problem once.
I absolutely do not understand how 3G and 4G relate to call signal strength, as it's been eluded to in other discussions. I'm getting the impression that it affects the signal strength for phone calls, but then how can I (on my old phone) toggle it off and still have signal for calls? When I drive into the heart of 4G LTE country I can turn off the data and still have 4 or 5 bars. What's the connection between data and phone signal strength?

Iphone in Great Britian discovers Apple tech problem - Signal Strength -

November 25, 2007
Signal trouble: British iPhone mystery
Is O2’s network to blame, or Apple’s (AAPL) iPhone?
That’s the question posed by more than a few British iPhone owners who purchased the device in the past two weeks and have been struggling ever since to get decent telephone reception on it.
The problem surfaced two days after the phone went on sale in the U.K. when “Matlock” in Derbyshire started a discussion thread on Apple’s support board entitled “UK 02 (poor signal strength/reception problems)”:
My iphone can barely pick up even the slightest signal, although on occasion can pick up 3 ars, only for it to drop out again. I have two other 02 phones, a Sony Erricson and a Nokia n95 with no reception problems at all. Is anyone experiencing same problem with their iphone, I would like to hear from you. (link)
Two weeks later, Matlock’s query has received more than 100 replies (and 3,723 pageviews), most of them registering similar complaints. Some users found that reinstalling the software made a difference. When others returned their phones for new ones, the problem went away (although some reported that the new phones were no better).
Definitive U.K. sales figures are not available, but O2 reported that it sold “tens of thousands” of iPhones the first weekend it was available.
Several posters on the Apple discussion board volunteered that unlike the complainants, they were getting great reception on their iPhones. And many owners with signal problems expressed pleasure with how well the device performed its other functions.
But unlike American iPhone owners, who tend to blame any reception headaches on AT&T’s (T) cellular network, the assumption in the U.K. seems to be that the signal problem is Apple’s. The impression is reinforced by O2, which has been referring callers directly to the manufacturer.
One clue is that many British iPhone owners can, like Matlock, compare the signal strength on their iPhone with other cellphones using the same network (one user even posted photos showing the phones side by side). Another is that the indicator on the iPhone tends to jump to five bars as soon as it is placed in the charging dock, which suggests that the problem is battery related. As user Richard Catledge points out:
It says in the manual that phone signal is adjusted to the minimum power when not in use, just enough to detect the incoming pings, then it will power up to get the best quality call. It is digital, so as long as the signal power is strong enough to reconstruct at the other end, more power is pointless. I suspect this is what you are seeing, or a slightly flakey implementation.
Meanwhile, the consensus on the discussion board is that unhappy owners should let Apple know. Writes one user who posts as ::…SAM…::,
The only way to get anything done about it is if people that have poor signal problems is to take your phone back and get it replaced. The more phones they get back, the sooner they will do something to fix the problem. Emails and complaints are fine, they can be put in a folder, high handset return numbers cant be so easy to hide under the rug.
Thanks to InformationWeek’s Alexander Wolfe for the link. See his report here.

Interesting post. My previous phone was an 02 XDA Exec, a smart phone based upon a common handset (forget which one), but the smart phone before that was the same. They all had one thing in common - poor reception.
tbh, I think its an inherent problem with smart phones. However, with my iPhone I haven't noticed anything out of the ordinary really. Its better than the XDA, at least the iPhone doesn't drop out completely!
But compare it to a normal handset and the normal handset will normally have a much better reception strength.

IPhone 5s call signal strength is 3 bars and my calls are breaking up?

I switched from an iPhone 4s to an iPhone 5s and now my iPhone signal strength is 3 bars and my calls are breaking up? what gives?
I live on top of a hill in a major metropolitan city and my carrier has always been Verizon and my call signal strength has always been 5 bars and occassionally on a cloudy rainy day I had 4 bars. Since upgrading to the 5s my call signal strength at my home has never gone past 3 bars even when Wi-Fi is connected. When W-Fi is turned off and LTE service kicks in, the call signal strength flutters between 2-3 bars and if I am on a call, the person on the other end is telling me I am breaking up. This has never happened with my iPhone 4, my iPhone 4s. Is anyone else noticing signal problems?

I am also having the same exact issue. I had an iPhone 4S with Sprint servince and always had at least 4 bars of service (4 dots after iOS7 upgrade) and I am now fluctuating between 1 and 2 dots on my new iPhone 5S. I am also having people I am on the phone with tell me that I sound like I'm in a tunnel and or that I am breaking up. I am also hearing the breakup of voice service even when speaking to someone on a landline. I took my first iPhone 5S back to the store and traded it in for a new one and am having the same exact problem with this new 5S phone. I was told by the salesman at the store that the problem was due to the 5S is using different towers than the 4S and that the new towers for the 5S were still being implemented. Do I know this to be true or necesarily believe this? No. Do I hope it's true or that Apple will come up with a fix for this problem in the very, very near future? Yes. Apple, what is going on with my service? It's obvious that it's happening to users from all of the major American networks.

WRT54G3G-ST: Signal Strength "meter" broken?

I am running a WRT54G3G-ST using the 2.00.9 firmware on Sprint with a Novatel Merlin S720.
I think that the signal strength meter does not actually work properly:
a. I can be connected just fine and have it display "No Signal"
b. Other than "No Signal" the only reading has been "Excellent" and I live in a fringe area with -90dB readings being very common for me which is FAR from "Excellent".
Does this meter work for anyone? If it does, which firmware? What gradations does it display? Which cards?
Linksys, it would be *REALLY* useful it the Status page would give an actual signal strength reading, SNR, which network (1xRTT vs EVDO Rev 0 vs EVDO Rev A). The card can deliver this information in the Sprint Connection Manager so it should not be terribly difficult for the router to display it. If you can't display the native data (seriously, this is the most useful data) then a graded bar graph would be better. Worst option is an unscaled word description - if it even works.

Well, good to hear that this bug is not specific to this firmware. Sounds like Linksys is getting signal information either incorrectly or at least inefficiently.
I updated my router firmware immediately (for card support) so I did not get a chance to see the original version.
Even the terrible D-Link DIR-450 give a 10 segment bar to indicate relative signal strength. They still should have displayed signal numebrs, SNR, network, etc., but at least you can kind of tell how you're doing from refresh to refresh. Saying "Excellent" when you know that you're in poor reception and/or reporting "No Signal" when you're online is not very helpful.
Linksys, is there a formal bug process or do we just leave messages here?

IMac G5 AirPort Issues - Very poor signal strength.

Disclaimer: I am normally a PC user, but just bought a iMac G5 for my son's bedroom. Problem is that I am having a **** of a time getting the iMac to stay connected to my network long enough to download a newest OS update and in general, it is very slow downloading webpages...clearly not normal...at least I hope not.
My connection is Broadband DSL to my main PC equipped with a Linksys WRT54G Broadband Router. My 2nd PC is connected wirelessly and is much further away than my iMac, but gets better reception.
Therefore, what is the deal with my iMac??? It seems to be super slow downloading the large software updates and has often timed out as they have bogged down.
As a PC guy, I am wondering is it an internal antenna issue in the iMac G5 or is it something as simple as Wi-Fi (AirPort) setting?
If is is a lousy internal antenna, what can I do to boost my signal strength? I was thinking of disabling the Wireless and buying Gaming Console access point to hard wire to the ethernet port. Is that possible? Would AirPort Express device be good for anything?
Help...I am ready to return my first Apple and go with a Dell!!!
Solutions???

Thanks Rod. Your comments were very helpful...
Apologies for the dash of sarcasm, M., but these things usually are just that simple to get running, and your Dell jokes started me down that path you know . Yes, I should have resisted the temptation.
Screen orientation really can make a difference in a low signal situation. So can simply changing the channel on which your wireless router operates (have you tried that yet?). You also can't assume that because a computer in a neighbouring room gets gets adequate signal , the one that you are working on will too. Walls, power circuits, nearby electrical gear, etc etc can all have highly localised effects with this stuff.
If, as it appears, you have adequate signal strength (I thought you indicated initially that you didn't have) and the problem is not related to local interference on the channel which the router is using (that's why you need to try a different channel) , then its time to check other aspects of the setup, both of the router and the iMac. The problem could be caused at either end.
Lets take the router first. The WRT54G usually actually works pretty well with Macs. In some cases, however, it may need a firmware update from the Linksys site. There have been quite a few different models of this particular router produced, so you'll need to check the downloads section at Linksys support for the correct one.
The best people here to answer this sort of stuff are probably Henry B. and Frank Canzolino . They both spend much of their time over in the Airport forums. If a firmware update for the router , or a simple channel change, doesn't fix the problem then I'd try posting there with "WRT54G and iMac G5 AE " displaying in the subject line.
As far as toast goes, I personally recommend asking the power company to drop the voltage for a few minutes. Saves all that time wasted knob twiddling.
Cheers

Full signal strength but unable to connect to the internet

I just got my ibook G4 about a month ago and have only been able to access the internet for about 2 weeks on and off. After I set up my wireless linksys router I was able to connect right away and it was fine. Then about a week or so after using it when I tried to open safari a message popped up telling me I was not connected to the internet. This lasted for about a week and then one day out of the blue I was able to connect. This lasted about a week and has since gone back to being unable to connect for the past 5 days. I have full airport signal strength and it recognizes linksys in the drop down menu.
I called Apple and was unfortunately disconnected but they advised me to reset the router by disconnecting it and plugging it back in after ten seconds. Still no luck. I even tried connecting through the cable that is normally connected to the desktop, still nothing.
Does anyone have any advice or know what could be wrong??
iBook G4 Mac OS X (10.4.2)

Megz, first welcome to the discussions,
Here are the recommended steps to regain your connection.
If you have not changed or fiddled with any of your settings.
1st Check and make sure all of your cables are good and plugged in all the way.
2nd, Shut your computer clear OFF.
3rd, Pull the AC adapter from your Internet Service Providers Modem.
Next Pull the AC adapter from your Router.
You will have to wait a minimum of 5 minutes.
Next In Order.
Plug back in your Internet Service Providers Modem after your 5 minute wait.
Now you need to wait untill it has regained it's signal from your ISP's server, to your modem, this normally takes a minute or so, or untill you have all the lights (normally 3).
Next you can plug back in your Router and repeat the process of waiting for all the lights again, about a minute.
Now you can turn your computer back on and you should be good.
If not, repeat the process and wait a little longer.
If there is a problem it is normally caused by not waiting untill you have re-aquired the signal form your ISP's Server. Good Luck Don

Weak Airport signal strength after MacBook upgrade to OS 10.5

Today, I finally upgraded my 13-inch 2.16 GHz Core 2 Duo MacBook (2 gig RAM, 160 gig HD) to OS 10.5 from OS 10.4.11. After using install and archive to install the new system, I noticed the Airport signal was down to three bars from the usual four. After completing all the system updates to bring it up to 10.5.8, its still receiving only three bars. We're using a 2Wire wireless DSL modem for Internet service. I was getting the full four bars before the system upgrade, and my wife's 14" G4 iBook is still getting four bars.
What's going on here? Is there an available fix for this? Or am I doomed to going back to OS 10.4.11?

Those bars are only an approximation of Wi-Fi signal strength. In Mac OS X 10.5 if you pull down the AirPort menu bar item while holding down an option key you'll see a value "RSSI", which is the actual signal strength. If you were using an AirPort base station, you could use AirPort Utility to see actual signal and noise levels.
In Mac OS X 10.4 I don't think that option key trick works, but you should be able to use the AirPort command-line utility, as describe in the electronic book "Take Control of Your 802.11n AirPort Network" (http://www.takecontrolbooks.com/airport-n):
- Launch Terminal
- Type this command:
cd /System/Library/PrivateFrameworks/\
Apple80211.framework/Versions/Current/Resources/
- Type this command:
./airport -s
You'll see the "RSSI" value in one of the columns. If you compare the "RSSI" values for both OS versions, you may find the "RSSI" values more similar than the AirPort menu bar arcs suggest.
I have no financial connection to Take Control Books.

Measuring signal strength between 2 bridges (1310s)

Hi:
I've been experiencing sporadic connectivity issues (losing association between root & non-root bridges, cannot ping remote bridge) at one of my customer's site. I am looking for a tool that will allow me to measure signal strength or noise ratio between 2 1310 wireless bridges. Does anyone know of any tools that will allow me to gather such information? Thanks for any feedback.

As mentioned above, you can look at the RSSI values; the traditional instrument-of-choice would be something like a spectrum analyzer ($$$ - possible to rent) connected to the antenna.
A spectrum analyzer will give you a sweep of the band and show you the signal strength in terms of db(microvolts) or dBm (power relative to a milliwatt) and will also show any persistent interference. Since you are seeing the direct signal, it can also be used to tweak the aim of the antennas as well (remember that there may also be differences in elevation as well as azimuth, so check the up-down as well as the left-right).
You will usually need someone at the other end to assist in verifying that you are looking at the correct signal.
If your bridges support a mode that permit simultaneous AP & bridge operation, something like NetStumbler (free, http://www.netstumbler.com )can give you signal and interference information. I don't think it supports bridge mode signaling (it might, I don't know), that's why it might be necessary to flip on AP mode for the testing.
Good Luck

Iphone signal strength

Hi folks,
Got a new 3GS. Now, I know that the iphone has poorer signal strength that most other "normal" phones on the market.
By "calling" 3001#12345# from the phone, one can see the signal strength. I put my friend's iphone 3G beside my 3GS and the level were different. It appeared that he had about a signal 5 higher than mine (e.g. I was at -71 and he was at -66). Sometimes, I had a higher strength than his but mostly, his was better.
Again, is this just me being fussy and comaring to different models of phone hence an unfair test? What you think?
Reason I'm concerned is that sometimes, when I have my phone in my pocket, it has no service when other phones (non-iphone phones) seem fine...
Thanks
Jonny

Regarding 3G service...
±5 dB on the numbers is pretty meaningless, especially at the levels you mentioned. My 3G has varied at least that much (±5) sitting in one spot. If they were 10-15 different, I'd be concerned. From my experience, anything from -50 to -85 is good enough for any app to work well. I get usable service up to about -115.
