Re: Slow 4G connection only, but only sometimes -- SOLVED
One thing to be aware of with wireless signals - and this applies to both the OP's experience and what @tjwellerjust posted - is that it's important to understand how obstructions affect signal quality, AND the physics of how signals are obstructed. One of the most counterintuitive aspects is that if a signal has to pass through a solid object (a wall, window pane, etc.), the closer you get to that obstruction, the more of the signal it blocks. The reason is simple trigonometry:When you pass through asolid object at an angle, it appears thinnest when you take an exactlyperpendicular path (pass through it head-on). If you approach it at an angle, the farther from perpendicular you get, the thicker the object appears. Consider this diagram: Signals passing through solid objects The red arrow represents a perpendicular path, the thickness of the object is the same as triangle side 'a'. But if we take the blue path, the length of side 'c' represents the apparent thickness of the object (in terms of the wireless signal). The length of 'c' can be computed in terms of 'a' and theangle at 'x'. (See formulas. The last one just solves fromPythagoras:c² = a² + b².) When x is 45°, c is roughly 1.4×a. When it's 30°, c is 2×a. At 15°, cgrows to nearly 4×a. Now, a wireless signal is nothing like astraight arrow; that's a massive oversimplification.In truth, the properties of wifi signals are almost impossibly complicated, andcalculating or predicting them is a science unto itself. But the basic premise herestill holds:A solid obstructionlike a wallwill obscure more of the signal being received at steep angles,whenyou're right next to it.Re: Can you set up the Home Internet using Ipad
@EspiritusIt sounds like the password may have been changed from the default at some point, possibly the device had been set up by someone elsebefore you received it. I'd suggest a factory reset, which should restore the password back to the original default. To factory-reset the Home Internet device, look for a small hole located just above the ethernet ports in the back. There's a reset button in there. Using something like a straightened paperclip, press the button and hold it in until the top of the device shows "Release for Factory Reset". (If you release it too soon, it'll reboot but not reset the password.) That should get you back to a state where you can set up the Home Internet from scratch.
