"Rock solid 4G connection, easy setup, fast, tiny"5.0 starson by RickRussellTX
Pros: Using the MiFi 4082 within range of Sprint 4G (aka WiMAX) network in Los Angeles, and having no problems at all. Windows, Linux (Ubuntu 11) and iPhone all connect seamlessly. Supports direct tether in Windows (no wireless network required for desktop syst
Cons: Takes about 2-3 full minutes to connect to Sprint 4G and stabilize before computer has Internet connectivity. The integrated 802.11g power is a bit weaker than a typical home router; don't expect this device to cover a whole house.
Summary: Unfortunate to read the negative experience of others; I can't really account for it except to say that I'm not having any similar problems. There was some initial confusion on setup -- the Sprint store could not activate it in-store (customer's computer is required for setup according to their docs), so they sent me home and I had to call the support number and get "escalated" tech support to activate it. Took 20 minutes, but no big deal.
dslreports.com speed tests range from 1.9 to 3.0 megabits/sec download and 1.2 to 1.5 megabits/sec upload. 4G connection has never dropped; I've gone into the admin console and turned off 3G so I'll know when I drop out of 4G range. I've been running almost constantly now for several days with no problems.
This really is a fine alternative to hardwired cable or DSL for the apartment dweller that doesn't want to get tied down to a contract, and the portability is icing on the cake. Base plan price of $45/mo for truly unlimited 4G data (3GB data on the 3G network) is very reasonable.
