High-Speed Wireless Ac: Fill & Download for Free

There might be 2 reasons :You've created a hidden WiFi network - No one will be able to see your WiFi Hotspot in their ‘available network’ list if you've created a hidden network. However, they can connect by manually adding your wifi details in Control Panel (for windows) or WiFi settings (for Android)You've created a Hotspot with 5 GHz band - This band is not supported by old devices. They can only detect 2.4 GHz band bcoz their adaptor supports only wireless a,b,g and n. You need to have a wireless adaptor which supports wireless ac to be able to detect 5GHz band. Most new devices have wireless ac, so they can detect 5GHz Wi-Fi network.5GHz band is used by some routers to avoid congestion in WiFi channels. 5GHz band is not provided by all routers. The low price range routers which most people use nowadays only support 2.4GHz band. Channel overlapping thus takes place to a high extent. This leads to problems like slow internet speed and reduced WiFi range due to congestion. So 5GHz band is used to avoid these problems caused by channel overlapping.

Building off some other answers I'd like to give a simpler but more complete answer in terms of how they come up with these numbers:These marketing terms are adding the max speed of each radio. They may support 300Mbps or even "1000MBps" on 2.4Ghz, and as high as 2166 per 5Ghz radio.AC1900 = 600 on 2.4GHz, 1300 on 5Ghz (rather ridiculous claim, as very few devices can achieve above 300Mbps on 802.11n, see note at end)AC2400 = 600 on 2.4GHz, 1733 on 5Ghz. They round up.AC 3200/5300 triband routers use a dedicated 5GHz radio only for 802.11ac, a 5Ghz radio for a/n/ac, and a 2.4Ghz radio for b/g/n. Add up the max theoretical speed of 802.11n, 600Mbps +1300Mbps on each 5Ghz radio for 802.11ac for AC3200. AC5300 is 1000Mbps 802.11n on the 2.4Ghz radio, and 2166Mbps on each 5Ghz radio. (Again, the 1000mbps claim for n is absurd)When looking for performance in a wireless AC router, look for the number of spatial streams it can support - typically spoken of in terms like "2x2 MIMO, 3x3 MU-MIMO, etc." The best you will likely see is 4x4 MU-MIMO. Keep in mind the client devices must also support this, and the geometry of antennae means you're not going to see beyond 2x2 wireless AC in a phone.Key takeaway is that "AC3200" marketing does not mean that a typical single device can achieve this speed. A single device could only achieve this speed if it also used three radios and used some form of load balancing.Note on 300Mbps+ 802.11n: These schemes use very high modulation schemes and 3x3 or 4x4 MIMO which are optional extensions to the 802.11n standard (read: almost no clients will support them). Most devices can only achieve 150Mbps per stream and support 1 or 2 streams. You cannot fit more than 2 2.4Ghz antennae in a phone to my knowledge due to the geometry of the antennae (must be a certain size and space apart, related to the wavelength of 2.4GHz signal) All this equipment is essentially nonsensical, and users seeking higher speeds should look to 802.11ac instead.

Wireless A and G only support data rates of up to 54 Mbps.Wireless N supports up to 150 Mbps and Wireless AC can handle rates up to 800 Mbps.Wireless G is over a decade old. Wireless N was introduced in 2009 and AC in 2013.However, that being said, hardwire is still much faster than wireless. I always use a hardwire when possible. Especially if I'm doing data transfers to my server.
