Nice tip, thanks.
I don't understand why config_SSID and config_ETH (or iwconfig_) can't handle
it.
Is there a bug on bugzilla for this? My search didn't give me any result.

Re: [gentoo-user] Wireless: Limit rate to strengthen connection?
I'm trying to strengthen a wireless connection that spans about 150 feet and has to go through about 5 walls. I bought two of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16833164110 for either end of the connection, but I'm having trouble making it work well. I've noticed the connection will be perfect for a short time, but then disappear. When watching iwconfig during this process, it looks like the connection is good when on a low rate, but when it goes to 54 Mbps it falls apart. Should limiting the rate solve this problem? If so, how can I do that? I'm using hostapd on the AP and wpa_supplicant on the client. - Grant Grant, Yes, lowering the rate to a slower speed will help greatly. The lower rates use less compression and modulation... less complex wave forms better connects over long hauls. The antennas look very good, but what's driving them? I use and whole heartedly endorse SENAO products and have had very good luck with these models: ECB-3220 (400 mw) or 2611CB3 PLUS (200 mw) at: http://www.wlansolution.com. Either unit with the high gain antennas you have, will penetrate what you stated and probably go pretty high on the speed scale doing it too. Should the adapter itself make a lot of difference when driving an external antenna? I think I'm going to use one of these with my laptop and an external antenna and I may need to pick up weak signals: http://www.newegg.com/Product/Product.aspx?Item=N82E16833315075 Does anyone know of a strong antenna that is more portable than this: http://www.newegg.com/Product/Product.aspx?Item=N82E16833164110 I'm mainly concerned with how much space it will take up in carry-on luggage. - Grant -- gentoo-user@lists.gentoo.org mailing list

I'm using a Netgear PCI adapter on the AP and an Edimax USB adapter

on the Gentoo AP or the client?

I use wireless-tools from portage. In it is iwconfig. A simple man
iwconfig
will show you what you need. Other thing you could do is configure the
Wireless AP for a fixed rate... works for me.
I found this:
rate_wlan0=( 5.5M )
which isn't documented in net.wireless, but it doesn't seem to have
any affect. I've tried it on the router and the client which uses
wpa_supplicant. I still see the rate on the client fluctuate all the
way up to 54 Mb/s in the output from iwconfig. The router's rate is
always reported as 0 kb/s.
- Grant
It appears 'iwconfig wlan0 rate 11M' works (at least as far as the
output from iwconfig is concerned) but how can I set /etc/conf.d/net
to always use this rate?
- Grant
The best way I found to do this is to just write your own script and run
it at the default runlevel. write a script called wireless-up save it in
your /root directory. Then in /etc/conf.d/local.start add the script
name to the list: /root/wireless-up. Make sure the script is executable
with chmod 666 /root/wireless-up. Here is what mine looks like. I laugh
when I read this thing that I call a script. I'll be upgrading this in
the future but for now maybe someone has a better idea and/or script.
#!/bin/bash
DATE=`date +%m_%d_%Y`
ifconfig wlan0 up || echo wlan up failed
iwconfig wlan0 essid ACCESSPOINTNAME || echo setting essid failed
iwconfig wlan0 mode Managed || echo setting mode to managed failed
iwconfig wlan0 key restricted YOURKEYHERE || echo key failed
verification
dhclient wlan0 || echo wlan0 failed to receive dhcp request response
# if [ $DATE -ne `date +%m_%d_%Y -r /tmp/.wireless.*
rm /tmp/.wireless.*
iwconfig /tmp/.wireless.$DATE
exit 0
For custom scrips, you can add a preup, failup or postup-function
to /etc/conf.d/net, there should be examples in the file.
Something like
pastup() {
if [[ ${IFACE} = wlan0 ]]; then
iwconfig [...]
fi
return 0
}
should work.

With careful antenna placement and use of 'iwconfig wlan0 rate 2M' I have a nice reliable connection. Thanks for the advice on lowering the rate. Does anyone think I would be better off with a 15 foot antenna extension cable and a PCI adapter than what I have now which is a USB adapter on the end of a 15 foot USB cable? I know antenna cables are lossy. - Grant -- gentoo-user@lists.gentoo.org mailing list
