Samsun SCH-LC11 4G Hotspot SLOW!

Got mine today.  Luckily, I don't deal with VPN much which they apparently have screwed up (http://community.vzw.com/t5/4G-Discussion/Samsung-SCH-LC11-Blocks-Microsoft-VPN/td-p/489618), something about this being a Home device not a Business Device ?? Right, purchased it off the Small Business page.

 

In my case, I'm not seeing great speed at all.   With a Thunderbolt sitting next to me getting 25MB, I'm seeing perhaps 2.5mb ??

 

I've seen panatech modems in operation near here getting 18-20mb so why am I getting such slow speeds?

 

Pings are like 455ms and a speed test places the hotspot in sounthern calif when I am in the Phoenix metro area.

 

I have a solid Green 4G light and the admin page looks like it has four boxes for the LTE 4G connection (they don't look like bars)

 

Don't see any update mechinism on the modem configuration pages for updating location/config etc...

 

BTW I get a lot of resets talking to the Hotspot via the admin page.  Sitting right next to the device with 99% Signal.

I got one of these the other day and I've had nothing but trouble with it. First, I would go in and switch the wifi to WPA2 and set a longer password. The device would restart and broadcast the network, but no password would work. I did a hard reset on the device 5 times and finally found a password that would work. Then, once I got the password working, my connection was flaky at best. Pings would run fine, but DNS queries would be VERY SLOW, as in 30-60 seconds (if at all). Changing to a different DNS server would work fine for about 30 seconds, then get slow again. Tried several DNS servers. After coming across this forum, I disabled the VPN option and switched the wifi to G only and it seems to have stabilized things. I pulled just under 16Mbit down and just under 8Mbit up in my most recent test. Not that it matters, but I'm using Firefox 4 on Debian 6. Hopefully things will remain stable.

Verizon is shipping a replacement unit to me today.  Should have it tomorrow.

Does anyone using a Windows XP know how to connect it? The speed seems fine on my Mac and iPod, but I can't connect this up to my Windows.

Thanks.

You switched to 802.11n correct? LTE is SO FAST like WiFi LAN that your WLAN maybe your bottleneck sometimes. (Though you may get up to 20Mbps with standard .11g).

Same problem here, I got the Pantech UML290 and yesterday I received the Samsung SCH-LC11, so far very disappointed, it keeps disconnecting all the time and is slower than my old MIFI 2200.

Went from the Pantech to the S SCH-LC11 and so far nothing but problems. Says I have a Green 4G connection and it's fully charged but it constantly disconnects from my MacBook Pro and shuts itself off. Speed Test are all over the place. Spent 1 hour with vzw tech support they replaced the unit. New unit does not shut off but still disconnects. Went to the Apple Store they set the encryption to WPA2 and router b/g/n and reset the card. This made things worse, not when it disconnects I have to reboot the MiFi completely.  My Laptop (PC) running Win XP seems slightly better, does not disconnect as much. But still pretty unreliable.

Similar problem here with a MacBook Air, also having problems with other computers (Mac and PC) but with the MacBook Air is impossible to connect.

I have found that 802.11n is buggy with this device.  If you change the setting back to the default of b/g everything works great.  I think they have wireless n problems.

I may give that a try, so stay with WPA2 but set back to b/g only

With all the trouble I have been having with my Slate using the 4G Hotspot, On monday I got a cheap ($8.85) Generic WiFi USB b/g adapter.  Plugged it in, to the slate, turned off the internal WiFi and set it up, and got great response from the 4G Hotspot (avg 20Mbps).

 

Not bad for a cheap WiFi USB Adapter.  Shows that at least some of the issues are with the computer side.

Just got one today. 10mb down and 1 up with a weak signal--actually quite impressed as I am close to the beach in CA and cell signals in general are not very good

You reboot the device correct? VZW has been fixing A-LOT of problems on their LTE/eHRPD network lately...

Update.  Spent the better part of an hour and more with Support on this.

 

Couple things...

 

1) we did the complete, reboot, reset thing with no change

2) I finally was able to test the device with another computer and phone (Droid) and it performed much better with those.

 

I have tried 3 phones (all droids) with typical down 7Mbps-10Mbps and up 1Mbps-3Mbps which for me is good enough.  Not anything like what the Thunderbolt users are getting but I have heard their up is kinda of bogus due to buffering using the speedtest app.

 

I have tried it on 5 additional notebooks and netbooks, again with good results.   Some upwards of 12Mbsp down with the best in the 19Mbps range.

 

Signal at both work and home is basically 100% or close to it.  So that is not the issue (coverage in Metro Phoenix appears to be good everywhere I go).  The web GUI makes it hard to see what the signal is, look like 4 Bars or boxes (they don't look like bars anymore in the web Gui).  The modem status shows typically 97% or around there.

 

So what is the problem... seems that the device which I actually got this primarily for, an HP Slate 500 is havig difficulty communicating with the device.  Speed is terrible and you can really see there is something wrong in that it times out all the time while using the web GUI admin pages on it even while sitting right next to the device.

 

Checking with HP on this now.  Note that most of the other notebooks I tested were HP's as well so it seem strange that the Slate would have issues with it.  It is unexpected as I have no other problems with other access points with the Slate.

 

Will try it at work tomorrow (today) on a couple iPad's and a iPad2 as well as a Xoom and Galaxy Tab to see if there are any issues there.

I just connected my new Samsung SCH-LC11 4G Mobile Hotspot.  In San Diego, CA area my first speedtest is 21.7Mb/s downloand and 8.58 Mb/s Upload at 104ms!  I'm VERY PLEASED!! 

I had the previous model LG VL600 4G USB modem and had similar results.  If anything, my new LC11 appears to be faster!  Maybe San Diego offers better speeds?  It's AWESOME!

What computer are you using to do the speed test with?

There needs to be a top for this device like they have setup for the Thunderbolt.

8.87Mbps down and 5.03 Mbps up, can't complain but 12 down would be much nicer.  Unfortunately, if they don't sort out the VPN issue this is going back.
