Hello everyone,

I'm planning to use the wl-500gp only with an external antenna, which is installed in a different room.
I dont want the internal pcb antenna to send emission.

=>Is it possible to deactivate this pcb antenna?

1. By software with the original Firmware? Or
2. by hardware ( "unplugging" the antenna, how is it connected on the pcb? directly or per plug?
3. By software using oleg? ( I would prefer point 1. or 2. because oleg takes a lot of time...)

Thanks for your help, scasi

well, if you have Olegs fw, it's not a big deal:

perform a 'wl > /tmp/harddisk/wltxt.txt' to see all possibilities (in file wltxt.txt)

have a closer look for 'wl antdiv 1' (or 0 or 3, see at the file wltxt.txt!!)
same thing with 'wl txant 1'

pleeeaase, be careful and read everything at first!!

If you are not firm with (for instance) winscp and/or console, please read all at first and search forum - if you destroy anything it's at your own risk!!

have fun

found out:

to point 1.: still not sure how to do it with the asus FW. Please post ideas!

2. not possible

3.newbiefan is right (thx!) :

antdiv Set antenna diversity for rx
0 - force use of antenna 0
1 - force use of antenna 1
3 - automatic selection of antenna diversity

txant Set the transmit antenna
0 - force use of antenna 0
1 - force use of antenna 1
3 - use the RX antenna selection that was in force during the most recently received good PLCP header

Thx to akbor

Does anybody know how to do this operation with the original FW?

At the moment I lack time for olegs...

Use 'WL antdiv 3' in http://router_IP/Main_AdmStatus_Content.asp to let the router use the best possible option. I think 0 is the internal antenna. Same with 'txant'

Hi,

"0" is the external antenna and "1" is the internal one. In Oleg's FW the diversity mode is set by default to the external antenna (both settings Rx and Tx)!

Thx to EddieZ and akbor.

I tried:


#!/bin/sh
wl down
wl antdiv 0
wl txant 0
wl up


wl up / down worked, antdiv and txant didnt.

The router continuously sends with 40% signal over a longer distance without the external antenna installed.

Any conclusions?

You can (must?) use txant and antdiv without turning off the device (wl down) :)

what is the difference between "wl up/down" and "wl radio on/off" ?

akbor

wl


up reinitialize and mark adapter up (operational)


down reset and mark adapter down (disabled)

...


radio Set the radio on or off.
"on" or "off"

I think "radio on/of" controlls only the radio transmitter/amplifier, "down" and "up" disables and enables whole network adapter. That's not necessary to disable and enable anything before changing the diversity. But it doesn't hurt either.
