hello guys,,
im using Archer T2uh for the wifi of my pc .
whie connecting to my range extender (RE6300)which gives me full speed of 54mbps which the isp provides me with wifi.
when i connect by 2.4 i get 75%+ signal strength while in my room with speed up to 25mbps but with 5ghz i get only 30% and below signal strength but speeds go upto 45 and 50mbps with very low signal . which i dont nder stand the the speed of 2.4 and 5ghz (Wi-Fi Speed:AC750 (N300 + AC433) are far higher than my isp speed but i get lower speed in 2.4 (even when nothing is connected to it) than 5 ghz which must be slower than the 2.4 because it has poor signal and i didn't come close to their speed cap

2.4 GHz only has 3 independent channels - 1, 6, and 11. The "channels" in between overlap some of the frequencies of these three channels. So it suffers a lot more from interference. Not to mention a ton of other stuff other than WiFi uses 2.4 GHz (bluetooth, baby monitors, wireless mice, car remotes, wireless microphones, etc). The signal strength will still be high because it depends only on distance to the router. But signal quality - the thing that determines throughput - is the signal-to-noise ratio (SNR). And interference from other WiFi networks increases the noise floor.

5 GHz has over a dozen independent channels, so interference is much less of a problem. Its signal strength drops quicker simply because it's...

I'm not sure what has you puzzled here.

WiFi works by broadcasting one source at a time. The speed of your connection is a maximum bandwidth available for any given set of circumstances: Signal strength, obstructions, and traffic on the frequency in question. So if you get only get 24mbps then that is all it can manage.

5Ghz is shorter range, higher bandwidth. If you are having difficulty with signal strength for 2.4Ghz, then 5Ghz is not a good alternative.

A range extender is acting as a communications hub, it must transmit and receive any and all data you are asking for. So your moden/router broadcasts the data you requested, the range extender reads it then re-transmits and your computer then receives it. You are automatically doubling your latency by doing so.

Were I you I would find a way to run a cable from your router.

i dont have any trouble with the 2.4 signal im saying that im not reaching the speed cap of it which is 300mbps and my isp speed is 54 .im saying that 5 ghz with poor signal get me speed double the 2.4 with 80 percent plus signal which is capped at 300 .

im thinking by logic and what they are saying . 2.4 have higher range but slower speed (ok) 5ghz lower range higher speed and lower penetration (ok) . if 2.4 speed is lower im not having a 400 mbps connection to reach its cap at 300 im just using 1/6 of it on the ther hand the 5ghz which has a speed 433 which is 8 times faster than my internet speed .
logic here comes 2.4 80% signal must be 40mbps+ out of 54mbps when no device is connecting and 5ghz must be 20mbps+ out of 54mbps.

sorry if im making it difficult or my bad english

5 GHz has over a dozen independent channels, so interference is much less of a problem. Its signal strength drops quicker simply because it's absorbed by solids and the atmosphere more quickly than 2.4 GHz. But as long as the SNR stays high that doesn't affect throughput.
