Samsung SCH-LC11 constantly turns-off

Has anyone had any luck keeping this device on and running for more than a few minutes? I have three people connected to the network and the device constantly shuts off. This is extremely aggrevating having to reboot the device every few minutes. I'm hoping someone has had some luck with this. I had read on another post that disabling the n-mode and changing the security type to WPA2 (AES) helped the stability, but that's definitely not the case.
I hope someone from Verizon/Samsung can speak to this because this is highly unacceptable for a $300 device.
Btw - it shut off on me twice while typing this.... ridiculous.

There is software update to address this issue with the device powering down with multiple users connected. My guess is the device does not have the newest software loaded. In order to download the latest software, please visit this link: http://www.samsung.com/us/support/downloads/SCH-LC11ZKAVZW.
Everyone that I have assisted has confirmed this resolves the issue with multiple devices connected causing the device to reset or power off. I hope this works for you as well. Please let us know if it does.

The service provided by the Samsung SCH-LC11 Mi-Fi device, and/or the 4G LTE service, is unusable.

I got the Samsung SCH-LC11 Mi-Fi device and 4G LTE service from Verizon about one week ago here in the Chicago area.
(Note: the first thing I did was update to the latest firmware (EF07) per the Samsung website.)
I am using it with my AT&T iPhone 4 with "Cellular Data" on the phone turned off completely.
I ran all the speed tests, 10 megabit up/down, wow, great.
Unfortunately, there are at least two major problems with it:
1) I noticed almost immediately that push emails stopped coming to my iPhone after a few minutes.
After looking into this in more detail I realized the following:
   a) The modem inside the Mi-Fi device is being assigned a 10-Net / "carrier-grade NAT" IP address, not a real Internet IP address. Fine, I don't really care as long as it works. I am not trying to use a VPN, or do VoIP, or run some webcam somewhere. In other words I'm not a "revenue leak" in Verizon "parlance" (I worked at Motorola during the OBEX fiasco days), but it's nice to know I'm being treated as such right off the bat.
   b) The "carrier grade NAT" appears to have a TCP timeout of no more than two minutes. I verified this by opening a telnet session to somewhere and not typing something for two minutes. After the two minutes I typed another character, but it never got echoed back and the connection was dropped. After waiting only a minute and a half, it lagged a little but sprang back to life.
   c) Problem is, push email relies on having an open TCP connection that is idle the vast majority of time. When an email comes in, the Exchange ActiveSync server sends a message back out to the device (over the existing connection) saying the mailbox has changed. Unfortunately, after two minutes of idle, the "carrier grade NAT" has dropped the translation entry a long time ago, so the connection is dead.
So I emailed support about this. (the ticket is "WFM87599752").
In the first round they told me to go look in the device's settings @ http://192.168.1.1. Yeah, did that already.
In round two, they blamed the dormancy timer. That's obviously not it, since the modem is layer two and knows nothing about TCP at all. Just to be sure though, I performed the test again, but this time I had a DOS window pinging Yahoo repeatedly so the modem wouldn't become dormant. Problem still happened. I saved the Wireshark PCAP here so anyone can see: http://home.comcast.net/~abcbwtxyz/two_minutes.pcap Frame #339 is where I try to type again, never to hear back.
2) The other problem is that as soon as a second person connects to the Mi-fi device over Wi-fi, the first person gets dropped almost immediately, and can't even reconnect again afterward. I mean, really? Made this video to illustrate: http://www.youtube.com/watch?v=Iadz4DGXFRM
So, can someone help? I know I'm not the only one having these problems; I sent the support alias the following links just as examples, there are many more:
http://himself.wordpress.com/2011/04/30/verizon-wireless-issuing-private-ip-addresses-to-3g-customers-class-a-nat-joy-and-gross-ineptitude-verizon-wireless-3g-fraudulent-enticement/

http://www.droidforums.net/forum/droid-x-tech-support/101185-droid-x-verizon-3g-assigning-10-nat-ips.html
-Chris

So just to follow up on this. I called to cancel today. The CSR wanted me to talk to tech support about my problems and talk me out of cancelling so I said fine. Summary of conversation:
1) Immediate acknowledgment that the two minute timeout of idle connections is by design, and no dispute that it breaks push email.
2) Disagreement with the claim that a second person logging on kicks off the first, even though I offered proof. Dismissed my point that other people have seen the same exact thing, saying that if you look up problems other people are having on the Internet, people say anything and everything.
Anyway, I continued with the cancellation; to their credit, they waived the activation fee and credited me for "time served", so I won't owe anything. I did appreciate that.

Samsung SCH-LC11 getting very hot

My Samsung SCH-LC11 is getting extremely hot to the touch. I'm also having the powering off issue. I updated the firmware and turned power off when idle to never.
I have to say that I'm disappointed with this device!!!

Not showing this is a known issue. Please send us a direct message with your name and contact number so that we can better assist you.

Samsung SCH-LC11 4G WIFI Standby

I know this is a result of the awful firmware with the device and want to see if anyone has figured out a fix.
My Samsung SCH-LC11 unit locks up and Green Light under the WIFI button stays constantly lit. In the manual it says that it is in Standby mode.
How do I get this to stop ?
Thanks....

Hello,
Based on the user manual, simply press the power button to get it out of standby mode. After 30 minutes of inactivity, the device will go into standby mode. Please view the link below for access to the user manual:

Samsung SCH-LC11 edit settings file

Does anyone know how to edit the settings file on a Samsung SCH-LC11. Specifically I want to allow it to still operate as a hotspot while charging.
I've seen a post on Cnet for a different Samsung hotspot for this. When I export the settings file on the SCH-LC11 it is not readable in notepad. What program do I need to read the file?
Any help would be appreciated.
Mark

Hello jmarkh,
The LC11 hotspot can be used while charging. Simply, turn it on and connect your wi-fi enabled devices. Once connected, you can plug the hotspot to the charge and the charger to a wall socket. Voila! If you have any additional questions then don't hesitate to reply to this message. ^AH

Samsung SCH-LC11 4G MIFI mobile hotspot - First Impressions #2

Yesterday, I received two Samsung 4G MIFIs to add to our corporate plan. These are also to serve as test units for evaluation for a possible upgrade of our 14 other 3G data lines (PCMCIA). Here are my first thoughts and impressions regarding this device. I apologize in advance for the length of the post and some of the more simple descriptions that might not need to be included. I've found that sometimes these minor steps become helpful to others with troubleshooting issues. I've found that they sometimes end up as "AH HA!" moments.
Out of the box: As soon as I opened the box, I was impressed by the size and styling of the adapter. Having not used or even seen one in person, it was a bit smaller than I was expecting. It's certainly small enough to fit into a shirt or pants pocket. For those that have not seen one, it's approximately half the height of a pack of cigarettes lying down.
Initial Setup: In general, this couldn't have been much simpler. After following the basic instructions (install battery, power on, connect and login), it was ready go. No activation phone number to call like I'm used to. *Reading other posts, it looks like these adapters don't always come pre-configured like mine was. It already had the SIM card installed and was ready to go. This must be a friendly service my local distributor does.
I love the fact that this unit does not need VZAccess Manager to run. Simply plugging the USB cable into a laptop will start charging the battery without putting it into a "single user" mode like other adaptors do. This simplifies things for IT administrators, as you don't have to explain multiple scenarios for how to use the device. Plus there are fewer options for the end user to mess things up.
Advanced Setup: This is where things start getting fun. My first task was to change the SSID and security key. I navigate over to the Network->WIFI tab. It took me a minute to figure out the whole profile thing, but when I went to make my changes on the "Manual Configuration" side, something still seemed out of place. I had drop down menus that didn't have any text in its fields.
Blank Field
This lead to a bit more confusion as to how the profiles worked. I decided to change things up and switch from IE 8.0.7601 to FireFox 4.0. Using FireFox, everything looked in place. I proceeded to configure the settings and then selected "apply". Apparently this wasn't the option I needed as all my settings reverted back. It looks like you need to select "Update Profile" first before applying the active profile. Great, now we are up and running!
Note: Both of my devices are running AP/Modem firmware: EC04
Speed Test: Curious to see how these new devices performed, I ran a number of speed tests while connected. My area has yet to be 4G enabled, so I wasn't expecting much in terms of an improvement with the 3G. On average I was getting 1mbps down and 500kbps up. This is actually slower than our current 3G cards that average 1.5mbps down and 768kbps up. Hopefully we get the 4G service sooner rather than later.
Deal Breaker: VPN. For my company, we use Windows VPN access. I spent a little time trying to connect to the VPN with this adaptor. For some reason I could not get past the authentication. I tried from multiple machines, using different OSes, still no luck. I contemplated making some changes on the server side, but decided against it as all other VPN connections (including 3G adaptors) were fine. That led me to these forums in search of an answer. More specifically, the current post on the exact same issue I was seeing.
http://community.vzw.com/t5/4G-Discussion/Samsung-SCH-LC11-Blocks-Microsoft-VPN/td-p/489618
I will do some additional testing, including some changes on the VPN server, but might have to send these back.
Summary: They look like great little devices, but in my opinion, are currently not quite suited towards some business environments. This could perhaps change with a firmware update or two.

Sorry to take so long to reply.... I now have a support community set up at http://www.netsubnet.com, or you can touch the support button on the SETUP tab inside of HotSpotSam.
Yes, that's the second request for signal strength, so it's on the planned feature list. I'm currently working on integrating the real artwork so that it's easier to see the current status - and the app looks a lot better too.
Next up is putting the status messages into a real log so if there's a problem or you just want to see what the app has been doing, you can scroll through it.
Also, I'll be putting the most common questions into an in-app help screen.
Then I'll work with the artist on the best way to show the signal bars on the main screen. The RSSI number on the INFO tab is the Received Signal Strength Indication (see http://en.wikipedia.org/wiki/Received_signal_strength_indication) ie "Signal Strength" so the info is out there just need to display it.
I'd also like to add an option to beep on low battery.
There have been thousands of downloads so I guess people find it useful! It would be nice if more people would rate and review, too.
Thanks for your suggestions.

Samsung SCH-LC11 4G Hotspot 4g LED not lit

Just got the Samsung SCH-LC11 4G Hotspot today. I live in an area where 4g is not available. The 3G LED is green and I have no issue accessing the internet but the 4G led is not lit at all. The manual gives no reason for the led to be dark. Any ideas?

Which lights for 4G / EVDO indicates which mode the Hotspot is working in. Only 1 mode can be used at a time.
If you are in an area where there is no 4G then the modem is not operating in 4G mode so the EVDO light should be lit instead.
You can see the modem status by using the Admin Web GUI (http://192.168.1.1) under Configuration -> Diagnostics.
When you press the Modem button, it will display info about the modem values, 2 of which will be the Signal for EVDO and 4G.

My iPhone 3GS is constantly turning off without warning. Help?

My iPhone 3GS has been constantly turning off and turning back on without warning, but my battery life is at 90%! It has been doing this for a few days, and it doesn't even stay on long enough for me to type in my password. I have tried charging it, holding in the sleep/home button, and turning it off. Nothing seems to work. Help?

Basic troubleshooting is reset, restart, restore.
Although the issue described could be a battery or system board issue.

Why does my phone constantly turn off on its own as if the battery is dead?

why does my phone constantly turn off on its own as if the battery is dead? Its so annoying! Every day once my battery life span is at about 40%, my phone will start shutting down with the dead battery sign once it is down. Then after about 3 minutes i can turn it back on.

Tons of people have this problem with iPhone 4S and 5, whether they are on iOS 6 or 7. You can only hope that one day Apple realizes that this bug (software ? hardware ?) is a *real* pain. So far, they haven't paid attention.

Samsung SCH-LC11 New Firmware

Hi All,
I was suprised to see this update when i checked for it manually. I used to get emails of these updates but didnt get any for this.
This update is purportedly supposed to fix the dreaded WiFi Disconnect Issue. I just upgraded mine and it seems ok so far.
Would love the community to check this out and post the results.
thanks

I think I found out my issue. The SCH-LC11 battery was very low (1%-5%) and in LTE mode it was consuming the battery faster than my laptop could charge it, even plugging it into the wall didn't help.
One of the flaws of the LC11 is that the device consumes more power that a computer (or the charger that comes with it) can provide. So the battery will eventually run down even it the LC11 is connected to a power supply.

QIP 7100 2 boxes constantly turning off

I've got 2 QIP 7100 2 boxes
they turn off constantly (go into standby)
this messes with my DVR!
I don't want verizon's DVR, i want my DVR to work. It would work great if the boxes would stay on for more than 30 minutes to 2 hours at a time.
What can be done?
thanks

The only I can suggest is to reboot the STB then go back in and check to make sure the sleep timer is set to never and see what happens.

Samsung SCH-LC11 experience in Las Vegas - not good

I was in Las Vegas last week for the HP Discover 2011 convention. This was a 10,000+ sized conference.
I have two datacards one from Sprint and the other Verizon, both 4G and WiFi connect. Both carriers have, at least according to the website, good coverage and I had a good signal showing. The event was held at The Venetian and my hotel was next door at Harrahs.
I ended up using my Sprint device most of the time.
First day, Sunday, Verizon was good. Monday could not get a 4G connection, or a 4G connection but data would not flow. 3G sometimes and very slow.. Had trouble next two days. Called Verizon and tech walked through normal stuff (turned on, signal, WiFi settings, etc...). We ended up resetting the device with the button under the battery cover and got it to work. At least until the following day when I was back to square one with the same original issues and could not use Verizon until I restored it to factory settings (used the browser interface this time).
Litterally, would power up my Sprint and I was going. This was clearly an issue with the SCH-LC11 and not my laptop.
With an event of that size naturally the wireless networks were busy or swamped. But I was very surprised and disappointed at how quickly the Verizon was not usable. 4G may not yet be ready for prime time.
If you travel, must have an Internet connection and are counting on this device/service, you might want to consider having a second carrier available.
I was very pleased with Verizon tech support and even got a followup call, but I could not use the device when I really needed it.

Hello dalewood,
I do understand the importance of being connected at all times. I know you are no longer in that area for us to further assist, but I do want to inquire if everything is working well for you now?

Tactic3D Rage Wireless Constantly Turns Off while Charging

I got the Tactic3D Rage Wireless a couple of years ago and it has had many problems from the time I received it. I eventually got the others fixed, or mostly fixed, but this one has been annoying me increasingly in the past few months.
The headset not only rapidly connects and disconnects with Windows 8 (I think it is a problem with windows and not the headset for this one), but it also turns off the second I turn it on while charging. This makes the headset completely useless when I am charging it. This would not be as bad, but now the headset will not actually charge when it is on its charger. After it "charges" for a few hours, I take it off of the charger and I immediately begin to hear the beeping, notifying me that the headset is low on battery.
I finally made an account on these forums after a couple of days failing at searching for this problem with others so now I am posting this. Help is greatly needed for I don't want to be forced to spend more money on another headset if I can get this one fixed. Please reply with any questions I have not answered, and have a good day.

Hi Logo594
You may want to refer to this article, specifically the last paragraph of the article regarding charging.
http://support.creative.com/kb/ShowA...spx?sid=111092
You also mentioned that this headset is at least a couple of years old, so it is possible that the battery
does not hold its charge well. If this still does not work, You may contact Support here.
Cheers,

Imac constantly turning off, sporadicly.

So, for about more than a year my mac has been turning off at random. Sometimes more often than not, but it happens atleast once a day.
I have tryed almost every solution, ive braught it in to apple sotre. But there is no problems they say.
Ihave tryed UPS, different sockets, but to no avail
It will work at other peoples houses, so i assumed it was a house problems. So we called in technitians and found no problems with the house, except high voltage. Is that a problem?
is there anything else i can try to resolve this issue?
open to anytrhing..

So, for about more than a year my mac has been turning off at random.
You should have called Apple tech support ASAP while you were under warranty. If you have AppleCare, strongly suggest that you call them and tell them exactly what you stated in your post. Make sure they are aware that the Apple Store told you "there was nothing wrong." You should have insisted especially if you were still under warranty or have AC.
When troubleshooting, make sure nothing is connected to your computer except for the keyboard & mouse. Try the following:
http://support.apple.com/kb/HT3964 Intel-based Macs: Resetting the System Management Controller (SMC)
If need be, take your computer to another Apple Store or an AASP for repairs. Not the one that told you nothing was wrong.
GOOD LUCK!

Mac OS 10.6.7 and Samsung SCH-LC11 Hotspot

Seems Mac OS 10.6.7 has an issue with keeping a connection when using WPA on certain wireless routers. The Samsung hotspot is one router that is an issue for this version of the OS. If you are having problems connecting with your MAC change the wireless security to WPA 2.
I'm not sure why Samsung decided to make WPA the default but I guess it is so the device is compatible with more wireless clients out of the box. I haven't tested WPA 2 with any other computers or wireless clients yet so I don't recommend this for other wireless clients if your device currently works with WPA.

Interesting; I dont have a problem with 10.6.7 and the LC11 with default settings.
