On the "Security" line click the drop down where it says WPA/Personal/PSK (TKIP)
Change this to WPA2/Personal/PSK (AES)
The password field just below it will now be blank.  Simply reenter the same password that you used before.
Click "Apply" at the bottom of the page.

 

 

 

I hope changing the encryption from WPA (TKIP) to WPA2 (AES) works as well for you as it did for me.  I have been cruising around for over an hour now with the 4G device and it's great.  Speedtest.net tells me I get about 18.75 Mb down and 4.75 Mb up with a latency of 85 ms.

 

Have fun, to learn more about Ubuntu Linux go to www.ubuntu.com


 

I have been using the Samsung 4G SCH-LC11 HotSopt for a week now, and have also noticed that web pages would freeze half-way through their loading process, and then pick back up about 20-30 seconds later. I have seen this when using a HP Netbook, Droid X and iPhone 4, when connected to the 4G HotSpot.

 

I tried your suggestion and changed the WiFi to "WPA2/Personal/PSK (AES)" but after using it today, I am still having the same problem as before, with web pages stalling while trying to load. The WiFi LED will just show a solid blue for 20-30 seconds, then start to flash while the web page finishes to load. This is also with the new firmware installed on the 4G HotSpot that Samsung posted on their support site.

 

The speeds are fast, about 12Mbps down using the speedtest.net app, but I wish that the web sites would fully load instead of freezing for 30 seconds half-way through.

Do we know if this solution has worked for anyone, the hard reset? 

This dropping every 2-3 minutes is maddening.

I have tried everything, doing the hard-reset, installing the new Samsung software, and changing the WiFi encryption type. I still get web page stalls.

Thanks for the tip. Using maverick here. Just made the change, have to see how it goes for a day or two.

 

Today I am only getting 3G where I was getting 4G before.

 

At least if it stays connected I am not worse off than before 4G.

Pretty much the same problem as others have reported.  The WiFi connection is lost after 3-4 minutes.  The WiFi LED goes out and never comes back on.  A power cylcle is required.

 

I updated the firmware to 1.0.011 which went smoothly enough, but no change in behavior after reconnecting and reconfiguring.

 

For the record, I'm using WPA-PSK2 (AES).  The fact that the WiFi LED goes out and stays out is a pretty good indicator that the device is the problem, not the security setting.

I'm not having any trouble with losing the WiFi connection, but in many locations, WiFi won't turn on at all.  I boot the device, all three lights flash and eventually the 4G light (sometimes the 3G light) will go green but the WiFi light is completely off.

 

I think it has something to do with WiFi congestion.  It happens when there are a bunch of busy WiFi networks in the area.  WiFi mostly works fine in my apartment during the day, but in the evening, it won't come on and my laptop lists like 20 other WiFi networks in the area.

 

Because of this (and the PPTP VPN problem), I was able to get my trial period extended by another 5 days and applied the firmware update, but it hasn't resolved the problem.  I have not switched from WPA to WPA2 yet -- don't see if that would affect whether WiFi turns on or not.

 

And, of course, since WiFi is off and USB can't be used for communication, I can't talk to the device at all when it's in that state.  D'oh!

 

Is anyone else seeing this variation of the problem -- no WiFi when the device is booted?

Find your answer here: http://community.vzw.com/t5/Broadband-Netbook-MiFi-Devices/Samsung-LC11-no-WiFi/td-p/506126

 

Short answer - it is WiFi congestion and a fix is on the way from Samsung.  In the interim, when you get WiFi to enable, log into the GUI and change the Channel Select from auto to a fixed channel.

Same problem as most - as little as 20 seconds to as much as about 4-5 minutes.

 

While working: 4G green light, Wifi blue blinking, Power Green

After a few minutes: 4G goes out, then white, then out... power goes from green to red... 4G and Wifi go blank... the finally power goes back to green but no 4G and no Wifi lights at all.

 

I have tried changing security setting to WPA2(AES) and have run the Wifi on channel 10, then channel 11 - has not helped.  This issues has just started today (5/3/11) and prior I had used the device for 3 or 4 days without any service interruptions.

 

Its been a VERY frustrating day - any other solutions out there?
