Connection drops out, must reboot?
I've been having trouble with my wireless connection dropping out after a period of inactivity as little as five minutes from booting (depends). I checked iwconfig, and everything looks good:
Code:
lo no wireless extensions. As it stands I have to keep an "active" connection, or reboot if I need remote access to it. I'm running Ubuntu 5.10. Any ideas? Thanks very much. |
Looks like you've used ndiswrapper (yes/no?), but what wireless care are you actually using and which drivers did you use?
|
I did install a driver for ndiswrapper (rt2500 - Win2K version, not WinXP), and it comes up okay: "Installed ndis drivers: rt2500 - driver present, hardware present." I've got a Belkin 802.11g desktop card (F5D7000, v3001); mine uses the RaLink RT2560, contrary to what is listed on the ndiswrapper list (http://ndiswrapper.sourceforge.net/m...index.php/List) - I've actually pried up the faceplate and checked the chipset.
Here's how dmesg reads: Code:
[4294692.249000] ndiswrapper version 1.4 loaded (preempt=no,smp=no) Thanks. |
I have the same problem, that my wifi connection may drop (maybe because of ap reboot, or maybe because of idle), and can't reconnect except reboot.
I'm also using ndiswrapper on Kubuntu 5.1.0 |
I've found the resolution of this problem!
use the following command to disable power management of wlan card: Code:
iwconfig wlan0 power off Code:
wireless_power off |
The original poster has already done that as evidenced by his first code block.
I can't think why this is happening other than to suggest that maybe there is a problem with the firmware that you used with ndiswrapper? Perhaps a different version? To reconnect without a reboot try Code:
ifconfig wlan0 down Added later.....just noticed that you're using Belkin kit. I've had nothing but trouble with Belkin wifi products with their constant desire to be rebooted/reset. If you can afford it junk them and replace with Linksys and/or USR stuff which for me have been troublefree. |
odd discovery
I whent through the steps to get better screen resolution out of the new open source nouveau graphics driver & ended up with a new custom kernel compiled for that purpose. As a side bennefit my wireless connection is much more reliable than before. I believe I checked built in support (not modular) for wireless when configuring the kernel. That may be of some use to somebody. I hope so!
