Thread: Broadcom 802.11g Network Adapter issues

-

basically few weeks ago decided try linux, in particular ubuntu. have installed in windows 7 partition willing take full plunge , switch way. issue cannot connect wireless internet. states "device not ready". wireless turned on on laptop, near source, have tried making manual connection network setup. tried hardware tester , found ethernet , wireless hardware (broadcom 802.11g network adapter).
went package thing , looked broadcam. found package installed. tried manually with:


sudo apt-get install bcmwl-modaliases
e: not lock /var/lib/dpkg/lock - open (11: resource temporarily unavailable)
e: unable lock administration directory (/var/lib/dpkg/), process using it?

heard try "sudo apt-get install bcm43xx-fwcutter" , did couldnt find it.



stated before new linux i'm missing easy
beg patiance learn new operating system.

i had same problem when replaced windows xp on laptop ubuntu 9.04. built in broadcom wireless adapter stopped working. during process of troubleshooting happened plug in usb wireless adapter , pleasantly surprised see connection established internet. once laptop on line of course run system updates. couple of days later system automatically reported new broadcom driver, albeit unsupported 1 had been found , if use it. when accepted that, adapter inside laptop started working , did not need usb adapter more.
when upgraded 9.10 same story unfolded again.
fortuitous rather researched solution works. if can lay hands on usb adapter way forward easy.

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

Arduino Uno + KTY81/210 temperature sensor

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
