rt2500usb goes to sleep

[gary101]

Hi All

Its a while since I have has to ask for any help, just shows how reliable puppy has been

I have just set up an new computer for the wife and it is using an Asus USB wifi adapter. No problems installing or setting up. I used ndiswrapper to install the driver (rt2500USB) and it works fine apart from one small glitch.

When the computer has been left for a while with nothing being sent between wireless adapter and router, the adapter seems to go to sleep and the connection is lost..

As soon as I go into Rutlit and scan, the router shows up again and you can carry on surfing, you dont even have to re-enter the key.

I know this is hardly life or death but it can be a bit annoying, especially when I get nagged about it!

Anyone got any ideas? Can I add a script to run at start up that will scan, say, every 2 or three minutes?

Any ideas welcomed, especially if it saves me getting earache! Lol

All the best
Gary

First, try using the Linux driver instead of ndiswrapper. It's rt2570, and the interface will be rausb0 instead of wlan0. That might give better overall performance. Or not. Worth a try though.

If that doesn't work, try this script to auto-scan:

Code: Select all

#!/bin/sh
while [ 1 ]; do
iwlist wlan0 scan
sleep 180
done

Be sure to replace wlan0 with whatever the interface is (probably wlan0 with ndiswrapper, and rausb0 with the linux driver, try running iwconfig if unsure). Then running this script should cause it to re-scan every two minutes. To adjust the interval, change the 180 (which is in seconds).

I also have two dongles using that driver (one a Belkin, the other a Nintendo Wi-Fi USB connector). I hardly use them, but I noticed the same thing last weekend at my grandma's house. I didn't take the time to test, but it seemed like the Nintendo one dropped out every so often, but the Belkin would mostly hold a connection (it held out for hours while I was watching TV with Grandma, but then was a little iffy while in use). Also, the two instances were in different locations with different amounts of stability (as in, the first case had the dongle sitting on my knee, whereas the second had it sitting on the corner of a mattress in another room).

I was using the Linux driver both times.

Maybe there's also a "no-sleep" style option, but I haven't bothered looking.


EDIT: That script doesn't have an "off switch". If you run it from rxvt, just hit ctrl-c. Otherwise if you saved it as an actual file and click it, killall filename should do it, otherwise look through the output of ps to find the process id (PID) and use kill 1337 where 1337 is the PID. Or you could build in fancier methods of control, add a gui, whatever. That's just an example to get you going. I didn't even use that, I just typed out the iwlist rausb0 scan, then after the first time of running it, whenever the connection dropped (while I was more or less using it) I'd just press up and enter to re-run it.

Thanks Pizzagood

I will give you script a try as soon as I get home from work.

I will probably stick with ndiswrapper driver if the script works as the adapter works fine apart from when it has not been used for a while.

Readind through the commands in the script this looks just what i am after.

Thanks again.

I had the same trouble with my Belkin F5D7630

MTU to 1400 was my only change.

The problem didn't completely go away but the hibernation considerably reduced.
