Bad Start - Signal Help?

I was a Sprint customer but sick of Commodore 64 dialup modem speeds so decided to switch to Verizon when the 5S came out. The map shows great coverage in my area, but to be sure I chatted with CSR and they confirmed I am good.
I woke up at 3am on release day, went online and completed my order around 320am. Expected shipping date was only 4 days away (9/24/13).
Then I got an email saying 10/7/13. I can live with that.
I checked on the 7th and my status was "Unknown shipping" with something about payment not received yet (even though my card had been charged.) I called in and the CSR expected it would ship the 14th. Status online never changed even though they had my money.
On 10/14 I called and was told it is at Fedex, and I'd get a shipping code that night. Didn't happen.
On 10/15 I called and was told that I was the second one to have an issue, but she assured me it was at Fedex and I'd get a shipping code that night. Didn't happen.
On 10/16 I called and was told that the 5S was on backorder, so could expect in 11/11. That was a no-go so I had her check, and she saw that the order was complete so I'd get a shipping code that night.
On 10/17 I called and was told that something didn't look right, the CSR was going to talk to warehouse and call me back that night. No call.
On 10/21 I called and got an ITC tracking code, and was told I'd have status that night. I called that night and was told I needed to wait 24 hours for status updates.
On 10/22 I called and was told that I should not have had an ITC tracking code, that whoever did that was wrong, and he guaranteed it would go out tonight.
FINALLY!
On 10/24 I received a call from the porting department. We went through and she confirmed that the port was all set.
I received my phone and (drumroll please) it would not activate. I called CSR and was told that the porting had not been entered yet, so to use my temporary phone number in the meantime. I don't have (nor did I want) a temporary number. He suggested I called porting.
Called porting, CSR couldn't figure out why. About 30 minutes later after elevating we had success! She called me on the line to test, and her call dropped. Sitting on my front porch I had one bar.
Most of my house has one or no bars. If I'm in the basement standing near a window I can get two. If I'm at the fence line of my far back yard I might even get three.
Needless to say - I'm not happy with the transition. And now I've gone from 5 bars with Sprint (they sent me a free Airave since they had a poor signal) to 0-1 bars with Verizon. What's the possible fix for 1) the repeated lies from CSR 2) the lack of CSR to see the actual coverage map and 3) my lack of coverage?

Only addressing the signal issue since trying to get a bally hooed new Apple device is going to be a real pain since everyone wants one.
In most cases there is no pin point for direct coverage. Look at a pie plate and make a pin hole in the center, then look at that pin hole as your cell tower. Closer to the tower gives better reception, farther away then the signal degrades. Verizon shows this map with all these red blotches, but there are white and gray blotches as well.
Take it from a business point of view when you are looking for service and the customer rep say's "Oh there is good coverage in your area" you believe them. Instead you know Sprint has good signal strength but you don't like their data speeds, Sprint is not fully out with their LTE service but calls are good. Verizon said everything was great but you never checked the service before you bought it. Yes in the area they might have service, and its 1x and 1 bar for voice service, you could try buying an extender from verizon but I think you will be wasting your money.
On T-Mobile certain devices have the ability to use your home wifi to make and receive calls, the iPhone alas has not the ability for it so that wouldnot help you. But you could ask a friend with one of their devices to let you see if their talk and data work better than what you have.
Sell the phone to another verizon customer to afford the Early Termination Fees and maybe ssome of the costs for a new device somewhere else.
Good Luck

TS5213 My internet sharing is not working at all. I turn it on and it shows no sign of being activated and my other devices don't even show its signals.Help!!

2 Macbook Pros don't see D-Link signal help please

Hoping someone might be able to help.
I have two macbook pros, and at work both connect without problem to my Dlink DIR300 router (the second I power up it connects...)
The problem begins when I get home, and both macbooks don't see the signal for the router, it's broadcasting normally, iphone and other pcs connect without problem (always) just the two macbooks never see the signal even when standing right next to the router... I bought a new router same model, worked a little and then same symptoms...
Is there any setting on the router that might be effecting something? the same model at work works perfectly...
Any help greatly appreciated...

do you know what encryption is being used?
is the same at work?

Can't get online- even with strong signal- HELP PLEASE!!!

I have an ibook G4 with an Airport Extreme Card. For the past few months I have been able to go online at home, with absolutely no problems. My desktop at home is a PC with high-speed modem and a wireless router connected. I also travel to school on a regular basis and can connect wirelessly there as well. My problem is, that for the past few days, I can't get online at home. I have a strong signal with the airport card, but both Safari and Firefox say "not connected to the internet" and tell me to refer to Network Diagnostics. I can't figure out why I can't get online. I have been at school during this time with the same laptop and have gone online with no problems at all. Not only that, but both my desktop at home, along with another laptop with wireless capabilities can also go online with no difficulties. I am new to Mac's so I don't have alot of knowledge. I am not sure if maybe my Network settings are wrong?? Any advice anyone could give would be sooo helpful. I have been pulling my hair out for days over this!

Try the following:
Delete Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
Delete AirPort Keychain Entries
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
- Restart, or log out then back in.
Add Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Add the preferred network(s) using the "+" button.
- Restart or log out then back in.

Befw11s4 Dead Radio - LEDs not lit, no signal - help!

Hi Linksys,
I've got several Linksys devices, including a G-router, and they're great.
But that's not what I'm writing about today....
In short: I fiddled with the WiFi in a vacation rental house, and I think I broke it.
The long:
I'm renting a house on cape cod, and they have a befw11s4 wifi router.
When we arrived, it was working. But since the SSID was broadcast as
"linksys", I was worried about privacy. So I logged in using the default
password "admin", and discovered that it was a typical default situation.
So I decided to turn on security for the week, then I'd turn it off. No
big deal, right?
Unfortunately, after turning on WEP security (it doesn't seem to have
WPA), the radio went dead. So I did a factory reset from the button, and
that didn't help. Then I hardwired with cat5 and did a factory reset
within the admin interface, and the radio is still dead. By "dead", I
mean that no SSID shows up at all. And the WLan lights (WLAN Activity,
WLAN Link) do not light up - ever. The setup screen looks like this:
Wireless: [x] Enable
SSID: linksys
Channel: 6
WEP: [x] Disable
Here is a screenshot:
http://www.thornsoft.com/Misc/linksys_setup.JPG
I've tried disabling/enabling the wireless, changing the SSID, switching
channels. I also have analyzed the WiFi with my spectrum analyzer
(doesn't everyone have one?) and it shows no radio signals in the 2.4Ghz
band, aside from my own Linksys router on channel 3, which I'm currently
using as an access point (I brought it in case the one in the rental unit
wasn't able to be secured!) Aside from my traffic on ch3, there's nothing
going on, including microwave ovens, baby monitors, etc... And I've tested
as close as 4 feet from the device.
Here's a screenshot, showing absolutely no traffic on ch6. You see my wifi router on ch3, but the one that I'm trying to fix is on ch6. Nothing, zilch, nada:
http://www.thornsoft.com/Misc/linksys_wifi_spectrum.JPG
Any ideas? Would upgrading firmware help? It's currently at 1.44.2z. I
don't know the rev of the device, as it's bolted to the wall.
Let me know what you think. If I've broken the radio, I'm just going to
install my router in place of theirs, and leave it behind. I'd rather buy
myself a new router than risk my $400 cleaning deposit...
Thanks,
Chris Thornton

Thanks for the reply.
This router is "rev 0" I guess, as it doesn't indicate a rev with the model number. So I'm already at the latest firmware for that rev (1.44.2z).
I re-flashed it anyway, just for kicks. Reset switch, then power off for an hour. Radio is still dead.
We're going to scrap it, switch in my working WRT54G, and the owner of the house is going to re-imburse me. I'll probably pick up a new WRT54G when I get home.
Anyway, it would be really helpful if you could indicate whether these radios do just quit, out of the blue like that.

Hi I got a 9320 and is downloading very slow but I do have a strong 3G signal help plz

Good

Hi and Welcome to the Community!
With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT
KB00510 How to register a BlackBerry smartphone with the wireless network
Please wait for one "registration" message to arrive to your Messages app
2) Resend Service Books
KB02830 Send the service books for the BlackBerry Internet Service
Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.
3) Reboot
With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Hopefully that will get things going again for you! If not, then you should contact your mobile service provider for formal support.
Good luck!
Occam's Razor nearly always applies when troubleshooting technology issues!
If anyone has been helpful to you, please show your appreciation by clicking the button inside of their post. Please click here and read, along with the threads to which it links, for helpful information to guide you as you proceed. I always recommend that you treat your BlackBerry like any other computing device, including using a regular backup schedule...click here for an article with instructions.

MSI 990FXA-GD65 No Monitor Signal - Help Please!

Hi all,
I'm new to the forum and new to building too, so go easy
I've just put together a newly built computer, but i've been stuck on an issue i cant figure out for the last two days. I get no signal to any form of monitor i plug in. The mother board powers up, the graphics card and every thing else including fans, all power up, i get the 8 phase lights come on in blue on the motherboard, however i get a no signal on any monitor i try.
I have read through so posts and tried most things suggested, including, booting from 1 ram in the first slot, traying a different graphics card that i know works (did that and still no signal), rebuilding the setup again. nothing works.
When i turn it on it does make 2 quick little beep noises? it does this as it starts up. Find below a list of parts i've used:
MSI990FXA-GD65 Motherboard
Asus 7770 HD 2GB GDDR5 1020MHz Graphics Card
AMD FX 3.5GHz 14.mb Black Edition Processor
Corsair CX600M PSU
Crucial Ballistix 2x8GB Tactical PC3 Ram
Anybody able to offer some advice? Otherwise i cant think of anything to do but try a different mother board.
Thanks,
Ethan.

On the box that the board came in-Can you tell me what the S/N Number is?
should be a set of numbers---601-7640-110B1209066693..
That will tell us what bios you might have on this...
If I am guessing by what you put in your first post you have a fx 6300 vishera?
let me know
601-7640-100B1303048283 I cant see anything t5has says vishera, how would i find out?
Quote from: xmad on 11-June-13, 23:44:15
Try each stick of ram alone then each in different ram slots. Make sure to clear the CMOS each time.
If that is of no help, try a different type of ram.
2 beeps = ram issue
Which CPU do you have exactly?
I have, no luck, made sure the power was off when i cleared CMOS as well. Is it likely both ram sticks are damaged? Or is it indicating there could be an issue on the mobo with the ram brackets?

No signal HELP ASAP

I've had no signal last 4 days! I got a new sim yesterday from ee because thought my old sim just broke. New sim worked fine last night till this morning and again no signal! Just says not registered on network! But I was making calls last night! Why is this?

Have you tried to manually select the network in settings.
What phone is it and what version android?
Depending on which phone you have there could be another reason for it, from requiring a software update to APNs

Unsupported Video Signal Help

I'm trying to set up and old Nintendo to my TV. It doesn't have regular AV cable ports, but it has composite cable ports. There is no input as 'AV', but it gas this thing called 'ColorStream HD'. I've tried to set it up through that, but the screen says 'Unsupported Video Signal'. I've tried to set it up with my Wii with the AV cables and it worked, but its like a black and white screen with little to no sound. So the video for the Wii works, but not my NES. Is there something that I'm doing wrong, or is my old console too old to be supported by new TV?

It won't work. ColorStream HD is expecting a HD signal of at least 480p and you're trying to send an SD signal from a composite output. You will have to try to find some type of adapter instead, perhaps like this:
http://www.amazon.com/Tmvel-HDMI2RCACVS-Composite-Converter-Blue-Ray/dp/B009A6PJKQ/ref=sr_1_1?ie=UTF...
Here's a little more info on ColorStream:

Phase difference from 2 signals(HELP!)

Hi! I'm having trouble finding accurate phase difference between two signals.. one signal is from the input serial communication arduino and the second signal is a simulated signal. I want to find the phase difference between these two. I've googled a lot and found many similar threads of phase difference measurements, but it won't work.
The phase angle from the simulated signal is correct but the reading of the phase angle from the input signal keeps changing and I could not find an exact phase angle or phase difference.
What do you think I should do?

Doing phase difference measurements using two completely separate sets of hardware is in general a bad idea. You need to think carefully about how to synchronize the acquisition clocks of the computer vs. the Arduino. Better would be to measure your signal and generate your reference using one system, i.e. every time through the Arduino's outer loop, have it measure the voltage and also generate a reference level based on the internal clock, and transfer both to the computer.
That said, unless you know the signal frequency very precisely a priori, the phase difference between a synthetic reference and a measured signal will inevitably drift with time, at a rate proportional to the difference between the nominal and actual frequencies of the sample signal.

UCMA 3.0: UserEndPoint BeginEstablish exception: Microsoft.Rtc.Signaling.ConnectionFailureException

Hello,
I'm using UCMA 3.0 to write a web service that creates a userEndpoint and attempts to register it via BeginEstablish(). Before this gets called, a CollaborationPlatform object is created and started, successfully. But when I try to establish
the userEndpoint, I get the following error:
Endpoint failed to establish: Microsoft.Rtc.Signaling.ConnectionFailureException:Unable to establish a connection. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a

Ok, I followed the procedures for 'General Application Activation' at the site Michael recommended. I'm still getting the same error:
Endpoint failed to establish: Microsoft.Rtc.Signaling.ConnectionFailureException:Unable to establish a connection. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period

The only place where I deviated was activating a port. The example uses port 6000. I entered port 5061, only
because the error I was getting specified that port. Is this correct?
I can see the application pool that I created in the Lync control panel, but its status is 'N/A' and has a red X under the Replication column. My application is also visable
under 'Trusted Application'
Any other ideas?

Same exact problem with my Apple TV. Worked like a charm the first two times we used it. Haven't used it in about a month, now no Apple logo when I turn it on, or the logo appears momentarily and distorted, and then an error message from my Samsung HD TV: Mode Not Supported.
What changed?
