"Great when works, but drawbacks make it less useful"0.5 starson by jaredmauch
Pros: This device is very fast when you are in a 4G/LTE area. When performing interactive tasks like SSH or remote-login to servers you will experience lan-like speeds.
Device is small and lightweight
Cons: There is a long list of Cons hence the poor rating:
- Device does not pass through PPTP(GRE) packets even when VPN passthrough is enabled
- If battery is low, it can not be used even with the provided AC charger, the battery will continue to be drained wi
Summary: This device replaced the Novatel MiFi 2200 for me as part of our corporate plan. I live at home in an area where the Verizon LTE coverage has not reached yet, and using the device on the 3G network seems to be fine if all you are doing is HTTP/web surfing. Any "advanced" user activity I must strongly recommend be avoided with the Samsung SCH-LC11 device. The device came with the older firmware that had the "stalling" problem so I upgraded it to the EC31 firmware. This meant finding a windows machine capable of running their software and spending an hour realizing that not all of the USB ports on that system would work. Certainly that part is not their problem, but it it is difficult to tell what is going on with the device in many cases. On the verizon 4G network you will be placed behind a NAT44 (CGN) device and no longer have a public IP address. This is generally not a problem as people are not connecting to your system. There are some issues that will arise as a result. The Samsung device does not passthrough PPTP properly, most specifically the GRE frames are not processed by the device. We have a variety of different networks that have varying access requirements as they're in different groups (IT vs Global Operations). The PPTP problem became our signature issue to replace all the samsung devices.
Other problems you will observe with the samsung (not seen with the Novatel 4510L in our testing):
- Problems changing towers/sessions dropped
- persistent tcp sessions dropped (eg: ssh, even with tcp keepalives enabled in the kernel)
- GRE/PPTP problem is not a NAT44/CGN issue but a Samsung specific issue.
- Inability of the device to remain charged, or be charged while in use.
For a business critical application, Samsung is clearly not prepared to address your needs. These items may be addressed in a newer hardware design or firmware update but we were unable to wait for them to solve it.
Hope this saves others comparable trouble with this device. If you don't understand my review, then you will likely be happy. If you do understand it, I suspect you will run away quickly.
