Thread: wi-fi stopped working after nfs installation

-

i have managed connect desktop (kubuntu 9.04, 2.6.28-11-generic kernel d-link dwa 110 usb wi-fi adapter) acer timeline 4810g laptop (ubuntu 9.04). went ok till morning installed nfs on both systems.

can see laptop network created on desktop (via iwlist), after try connect (iwconfig wlan0 essid _my_essid_) ping of desktop returns
code:
from 192.168.1.1 icmp_seq=6 destination host unreachable
dmesg | grep wlan returns now
code:
[ 3502.027059] wlan0: trigger new scan find ibss join  [ 3504.968034] wlan0: trigger new scan find ibss join  [ 3507.872033] wlan0: trigger new scan find ibss join  [ 3510.668039] wlan0: trigger new scan find ibss join  [ 3511.473337] wlan0: creating new ibss network, bssid f2:96:e6:84:c6:2d  [ 3512.676031] wlan0: no ipv6 routers present  [ 3541.488046] wlan0: no active ibss stas - trying scan other ibss networks same ssid (merge)  [ 3572.312129] wlan0: no active ibss stas - trying scan other ibss networks same ssid (merge)  [ 3603.124035] wlan0: no active ibss stas - trying scan other ibss networks same ssid (merge)  [ 3603.969610] wlan0: selected ibss bssid 8a:9f:71:7a:97:51 based on configured ssid
on desktop , similar on laptop.

there weren't such messages before nfs installation, though i'm not sure installation caused problem.
code:
wlan0: no ipv6 routers present
mean?

how connect? don't use network managers, connect manually, using following procedure on desktop , similar 1 on laptop:
code:
sudo ifconfig wlan0 down  sudo iwconfig wlan0 mode ad-hoc  sudo iwconfig wlan0 channel 1  sudo iwconfig wlan0 key off  sudo ifconfig wlan0  sudo ifconfig wlan0 192.168.1.1  sudo iwconfig wlan0 essid '2111'

for it's worth, here's use--

ifconfig wlan0 up
iwconfig wlan0 essid ...
iwconfig wlan0 channel 11
iwconfig wlan0 mode managed
iwconfig wlan0 key ...
iwconfig wlan0 key open
dhclient wlan0

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
