Broadcom Wireless Drivers Installation : Ubuntu[SOLVED]

While one installs a fresh Ubuntu OS in any machine,typically he finds an initial deterrent as the Wifi adapter is not found  installed.This post gives a step by step direction on how and what to do,to get the Wifi working....and this happens since the same is not installed by default.

Since the PCI.ID initials for any Wifi broadcom adapter is prefixed 14e4,thus first we need to find the exact PCI.ID

Type 

lspci -nn -d 14e4:

Once you get the PCI.ID,you just need to ref the following table and find the corresponding driver to be installed.In our case is 14e4:4365 rev 01,so we choos the corresponding bcmwl-kernel-source

PCI.ID              14.04 LTS                        16.04+

MOST AMAZING TECHNIQUE TO TRANSFER DATA:SLURP

1. This is by far the most amazing thing I have seen in recent years....we have all seen ways to transfer data from one PC to other including bluetooth,wifi,cable and so on.....but this one involvesslurping up (extracting) information and squirting out (injecting) pointers to digital objects. Hence, information can be transferred from machine to machine without any kind of wired or unwired connection.It will be really clear when you see the above video.....you use a dropper like object to pick up a folder from one desktop to other......AMAZZZZINGGG!!!!!!

2. This clever innovation comes in from a former MIT Media Lab student, Jamie Zigelbaum.

"GOOGLE STREET VIEW" - FIGHTING PRIVACY ISSUES

1. Ever heard of google's street view application...m sure many of you must have...for those who have not heard of it...in brief it refers to a technology featured in Google Maps and Google Earth that provisions isometric views from various positions along many streets in the world. Launched on May 25, 2007 the application displays images taken from a fleet of specially adapted cars. Areas not accessible by car are sometimes covered by Google tricycles. On each of these vehicles there are nine directional cameras for 360° views at a height of about 2.5 meters, GPS units for positioning and three laser range scanners for the measuring of up to 50 meters 180° in the front of the vehicle. There are also 3G/GSM/Wi-Fi antennas for scanning 3G/GSM and Wi-Fi hotspots.

2. No about the fighting issue that i have reffered in the subject topic.Now whether it is a facility for the world base users to utilize viewing live views of streets world vide or it is an attempt to log in to the private data of the users across.....yess...I repeat it is the private data of the users avaiable from the open WiFi signals from their home computers and laptops.The intresting thing is that Google has accepted this collection of data from unencrypted wireless networks....and they have put the blame on a masoom software engineer.Google says the massive furore over Wifi snooping by Street View cars was all the fault of one software engineer.In an interview ,CEO Eric Schmidt said the whole affair came about because a software engineer inserted unauthorised code into the Street View system software. The man is now under investigation internally by the company as per posts on google blog.

3. Now what ever answer that google may come up with in form a mistake or simply putting the blame on that software engineer(...where was the Software Testing deptt and QC then otherwise?),the point that I intend putting accross is that just take care of envryting your WiFi router.Google has at least accepted the fact and mistake and they are taking measures to rectify it...but it will not be always like that.....there are so many mis adventurists present all around that looking around that unencrypted wireless networks for misuse.....just read this post again to avoid becoming a target like others.

WiFi at home : Take precautions

1. Accessing WiFi at home is no more limited to tech geeks as the simple configuration has made it accessible to even a layman who hardly has any know how of how it works and what are the dangers floating around if he goes with the default settings.The two year back case of a hacker emailing from an open WiFi account in Mumbai reflects the deep dangers associated with such mishaps.Following are a set of desirable config changes any WiFi account holder at home and office whould take care of while configuring.....

Step 1: Change the default password

Step: 2: Change the default IP address

Step 3: Disable the DHCP service

DHCP (Dynamic Host Configuration Protocol) enables remote computers connected to the router to obtain an IP address and join the network without needing to know the IP and router address information. This is a simple and effective way of keeping intruders away. As far as possible, set up the computers on your network with static IP addresses. If you still want to use DHCP to make your own configuration easier, restrict the number of DHCP IP users to the number of computers on your network. For example, if you have five laptops running on the network, limit the DHCP IP addresses to 5 from the default 50.

Step 4: Restrict the network mode

Step 5: Change the default SSID

Step 6: Opt for WPA2 or PSK security over WEP

Step 7: Enable the MAC Filter

Step 8: Use the router’s firewall

Step 9: Use Internet Access Policies

Step 10: Disable remote administration

Step 11: Switch off the router when not in use

Step 12: Disconnect the Internet when not needed

Step 13: Position your router carefully

Step 14: Update the router firmware

Step 15: Scan for signal leaks from time to time
