boost your transmission power from 19mW to 84mW

[Antiloop]

how to increase the transmission power from 19mW to 84mW

open up the 'System Command' page at
http://my.router/Main_AdmStatus_Content.asp

enter as shown below in the photo the following command:

/usr/sbin/wl -i eth2 txpwr 84

and push the Refresh button (DO NOT hit the enter your keyboard, the command won't be executed then)


well now you think your signal has been boosted to 84mW ?
yes correct, but i've discovered today (could be because of the distance tested @2meters from AP) some sideeffects

see below for your own conclusion:

It's maybe worth a try to see were the turning point lies. Find out what the ideal power is.

Did you also try the communication after a reboot? I read on other forums that it after reboot (of the client, not the router) they did get better results.

Sweet,... i haven't tried boosting the signal, but that page lets you use standard linux commands like ls, ifconfig and netstat.

I'll play with it.

can you see how printer sharing is done? Maybe they use an open protocol easy to use on mac os x or linux machines?

Hi all,
I've written this little script which you can run in your Startup.
It will set the power to 84mW.

Just create a textfile, copy the code into it, rename it to "bla.vbs" and go!

To run it you'll need Windows (VBS engine) and IE.

'===start copying here===

Dim w,url,pwrcode,userid,password
userid="youradminuserid"
password="yourpassword"

url="http://" & userid & ":" & password & "@my.router/Main_AdmStatus_Content.asp"
pwrcode="wl -i eth2 txpwr 84"

'create internet explorer object
on error resume next
Set w=CreateObject("internetexplorer.application")
if w is nothing or err.number<>0 then
    msgbox "Can't create IE!"
end if

'login and wait for it
w.navigate2 url
do while w.busy
    doevents
loop

'now "enter" the code
w.document.forms(0).SystemCmd.value=pwrcode

'and submit the form
w.document.forms(0).submit

'again wait for it to end
do while w.busy
    doevents
loop

'clean up
set w=nothing
msgbox "Power level set to 84mW"

'===end copying===

nice one,

could you change it so we have the possibility to to a set of commands in one click ?

or have a popup screen where we can fill in the command and maybe a output windows if possible ?

[Marrik]

Sure, just tell me what you like and I will integrate it.

[Marrik]

Here's the updated script.
It will prompt for an input (prefilled with the power line) for the command to enter.

Dim w,url,pwrcode,userid,password,bexit
userid="youruserid"
password="yourpassword"
bexit=false

url="http://" & userid & ":" & password & "@my.router/Main_AdmStatus_Content.asp"
pwrcode="/usr/sbin/wl -i eth2 txpwr 84"

'create internet explorer object
on error resume next
Set w=CreateObject("internetexplorer.application")
if w is nothing or err.number<>0 then
    msgbox "Can't create IE!"
    bexit=true
end if

pwrcode=inputbox("Please enter the command","ASUS Commander",pwrcode)

If pwrcode<>"" and not bexit Then
    'login and wait for it
    w.navigate2 url
    do while w.busy
        doevents
    loop

    'now "enter" the code
    w.document.forms(0).SystemCmd.value=pwrcode

    'and submit the form
    w.document.forms(0).submit

    'again wait for it to end
    do while w.busy
        doevents
    loop
    msgbox "Command executed!"
end if

'clean up
set w=nothing

Antiloop: If you want email me, maybe we can build a tool in ASP(.NET) or VB(.NET).

A good work, Marrik, thanks a lot! I think it would be nice if you could make a script for complete Telnet activation. It won't be so easy but maybe it would be possible to make it. What the script should do is:
1) open 12 HTTP links for FTP datemon activation
2) open the FTP root and copy necessary files (busybox, telnetd,...) stored somewhere on local HDD to the router's /tmp folder
3) perform commands for Telnet daemon activation (chmod a+x /tmp/busybox, ....).

Thanks again for your effort!

[Marrik]

It's no problem to execute more than 1 statement.
However, in scripting it's difficult to wait for the browser to complete. Sometimes it will return a 'complete' message while it's still busy.

I can build it in VB or VB.NET easily, even ASP (.NET).

But the 'beauty' of it was that you could put the script in your startup folder and then it would set the powerlevel every time you boot your computer.
When I build an interface into it (like in the last version of the script) then you NEED to enter the command.

Hmmm.....maybe some kind of script generator....

Let me know what you want/think.

hello

i tried your script
but when i enter anything varying from 2 to 84 nothing happens.
the signal always stays the same... ?

in the room in which i tested the signal is always 3 stripes, no matter if i use 2 mW or 82 mW

Is it safe for the router to set the power up to 84mW. How far can I go without damaging the router by overheating...
With maximum power won't it cook something near the antena?

possible it's not safe, those things are at your risk.
maybe an idea for you to measure the temperature for some time. with and without the boost, and publish them here

[Marrik]

I think that the max. output power is 84mW.
In version 1.7.5.6 of the firmware you can set it to this maximum.
