Remember, the soreness can be caused by any of the twenty-six bones, thirty-three joints, or the more than 100 muscles, ligaments, and tendons in the foot. Here is a look at the most common causes of sore feet, based on region: 1  Heel: Plantar fasciitis, heel spurs, calluses, and dry, cracked heels. 2  Arch: Flat feet, pes planus or fallen arches, plantar warts, Metatarsalgia, pes cavus, and overpronation. 3  Toes: Broken toe, bunions, hallux rigidus, turf toe, and hallux limitus.
Range is not an issue for me. I am more interested in the ideal setting for higher quality wifi calls. b) Auto (20 MHz or 40 MHz). Each 'band' or channel on the WiFi 2.4GHz is 5Mhz ... channel 6 for example uses 20HMz and there is a guard band or gap between that and the outside of challel 11. Setting 40Mhz gives 'you' mor bandwidth, and opens you up for more interference from/to others.
Cable broadband Internet connections in some countries go up to 100 Mbps. 802.11n WiFi is capable of 600 Mbps. But your particular WiFi router might not provide that speed. Older WiFi devices might operate at 54 Mbps or lower. In both cases, you won't see 100 Mbps of data because some proportion is consumed in low-level packet overheads and background chatter between devices.
