5 ghz signal weaker than 2,4 ghz signal #221

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. seems to be with original firmware as with custom firmwares
2. even with laptop directy placed by router signal is 15 to 20 db weaker
3.

What is the expected output? What do you see instead?
i think both radio signals should have same strength

What version of the product are you using? On what operating system?
using firmware 1.0.1.8e-p1, win7 ultimate 64bit with intel 5300 agn

Please describe the problem as detailed as it's possible.
If you have connection problem, then syslog file is required. (please do
attach it as a file)
Note that if there will be a poor problem description the issue status will
be changed to 'Invalid'!
"inssider 2.0" always shows a 15 to 20 db weaker signal on the 5 ghz band, 
router and laptop in the same room, nobody else on the 5 ghz band, 2 weak 
neighbour signals on 2,4 ghz band. is there any way to increase 5 ghz signal? 
or is this normal?

router was hard resetet and left all to default values, only channel width on 5 
ghz band was changed from 20/40 mhz to 40 mhz.
TX power is set to default 100

laptop is usually 4m in direct sight away from router and i only get -50 db 
signal strength on 5 ghz, on 2,4 ghz band i get -30 db.

connection is very stable, the only problem is the highest copy speed i get is 
about 12 MB/s to a wired connected computer.

with laptop also wired connected i get about 80 MB/s to the same computer..... 
MB/s = MegaBytes per second not Mbit :)

thanks for this great firmware, much better than the asus :)

yes can confirm this observation, with 2 Samsung Galaxy S2 phones, but was the 
same with original ASUS firmware. Might also be a receiver issue on the client 
side, would be more my guess..

Yeah thats just normal. I think the problem for you is the client receiver as 
said above. However 5GHz signal will not reach the same distance as 2G. This is 
belonged to the bigger signal waves (frequencies) 5G needs. 12MB/s tranfer rate 
for wlan n is absolutley normal and a good result.

And for 12MB/s @ wired connection is caused by the client nic or his poor 
ressources like small cpu or other and not the router. I easiley can achieve 
95MB/s and above. Maybe the nic in your pc is only a 100Mbit one that sounds 
familiar to me with 12MB/s thats the result u can achieve with 100Mbit 
connection.

2 regi@stuffmail.de: You should go to the nearest library and ask "Physics" 
school-book

@chris: I fully agree to what you said above, except your wave theory in (2), 
actually 5GHz has a smaller (~half) wavelength due to the higher frequency, 
l(ambda) = c / f, back to school as d... said lol
but the wavelength primarily has nothing to do with the amplitude, e.g. the 
signal strength. I'm not really up-to-date on this very high frequency 
electronics, but could imagine that 5 GHz transmitter and receiver is more of a 
challenge on the hardware side than 2.4 GHz..
