Windows 8 - WiFi adapter finds no wireless networks! ends up with "No networks found"


I have a Dell Inspiron n5110 machine with Intel Celerino WiFi N1030.


Its been about two weeks I have started using Windows 8. Formerly, I was using Windows 7 Home premium in which I had no any problem. Yesterday morning, when I tried to connect my WiFi, I found a red cross in the WiFi bars. I thought it might have been disabled but it wasn't. Driver was installed and windows didn't find any problem with the driver and the adapter itself. I tried reinstalling the driver but it didn't work. Thought the adapter might be malfuntioning; booted Linux from USB and the adapter was detecting wireless networks. And lastly, I tried System Restore to the last time when it was working.


But Ethernet works well.


EDIT: I downloaded the latest driver from Intel for Windows 8 and installed WiFi connection utility. And the connection utility actually detects wireless networks but the network doesn't show up in Networks.



Answer



You know the adaptor is fine because it works in another operating system. You also know the network is correctly configured on the modem/router end because you can connect okay via Ethernet. That means we are either looking at a physical problem or a configuration issue.


Physical problems with wireless cards are generally caused by poor reception. To check this try booting back into Linux and checking the strength of your wireless network by using a tool such as Stumbler (http://tools.meraki.com/stumbler). You would be surprised how often nuances in the driver code mean signal strength is sufficient in one operating system but not another.


As for configuration there are a number of things you can look at.


Start by going into Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings and check the wireless adaptor is enabled. This is a basic one and not likely to be the cause of your problem as the connection utility is detecting the network settings.


Failing that go into Device Manager. Find your wireless network card under "Network adaptors". Right click and go properties. There are quite a few things to check.




  1. In the general tab check the Device Status says "This device is working properly."




  2. In the advanced tab check the properties are correctly set. Most of these are tech jargon so be sure to use jargon. In particular look at power management properties and turn these off.




  3. Related to that last point untick all power management in the power management tab.




  4. Finally we come to the driver tab. In my experience this is where your problem will lie. The Intel Celerino WiFi N1030 for installing with the wrong drivers. I know you said you got the most up-to-date drivers but try getting them from Dell not Intel.




If none of the above works return to the list of network adaptors in device manager and check for duplicate devices. Be sure to enable showing hidden devices. In particular you are looking out for duplicate: Microsoft ISATAP Adapters, or Microsoft Virtual WiFI Miniport Adapters, or Wan Miniport Drivers.


One final pointer, I have experienced it in the past where this is caused by overheating not anything to do with drivers. If this becomes an intermittent problem try monitoring the temperature of your computer.


This is a comprehensive so if you follow my steps you will fix your problem. Good luck buddy!

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
