Yes that's correct method use that on clients laptops to clear out issues. Check all in the box to the right except for the IPV6 uncheck that. Can you download for your Android tablet the app called: Android Status. That app will tell me how your Android is connecting to your network. You'll need screen dump app for your android tablet so you could send me picture of your results for android status or you can use a digital camera which it does look like your doing above.

Your Signal is -58 did you test run AS in the same room where your WiFi Router is? I see you have All-Winner MPU. Which make and model is that tablet? I see your not rooted yet or you never use AdFree to block the ads..

Also where are we at now with your issues?

Yeah it was done in the same room and my tablet is a Samsung Galaxy Tab 2 (model: GT-P3110).
The internet is just simply not working on my Sony VAIO laptop, by using both an Ethernet cable or wirelessly. Even though it's working on all other devices within the household.

Try this::: bellow (also if all else fails you could do one more thing) You'll need to use another PC get a memory stick or SD card. get the drivers for the SONY VIAO WiFI and LAN) Remove all drivers for WiFi/LAN Under Networking and delete them off the PC. BUT ONLY DO THIS IF YOU HAVE THE DRIVERS like I had described.

I appreciate your help but this all sounds really confusing and past my technical level, I wouldn't know where to start or how go about this process properly, is there any other options I could try in order to find out what is wrong with my laptop and fix it?

This is the type of trouble shooting that would be done if someone where to work on it. Not confusing but a good understanding to how to fix the issue. There are so many factors to consider. Here can only do so much online than onsite would be better.

For some odd reason your laptop has VMware on it and that software attaches it's self to the Network TCP/IP side of your laptop. So in your case when the laptop was working then you were okay but when you came back here and said after the HOST files it wasn't working again.

So there is something wrong on that laptop.

Most of what I had suggested would bring the laptop to a state were it would be able to get a fresh start.

Since both Wired and Wireless is not working now.
If you were to

right click on the Computer link in start menu the click on properties
click on device manager
click on network adapter

Wireless
Wired

Connections uninstall the drivers for both but don't delete them.

Reboot the laptop.
Windows will install both of those devices.

Try now, if not, then your going to have to remove the VMWare off your laptop.
Then your going to have to clean-up the system. That's not hard to do.

Hi
I am facing a similar problem with my laptop(dell Inspiron) and mac book pro. While I am able to detect and connect to my home wifi on my ipad, my laptop and MacBook Pro are not detecting the wifi network. Have checked the hosts file in the address you had specified. It only has comments and does not have any local host file. Could you please help

There should be a HOSTS file located at
\windows\system32\drivers\etc

the host file should ALWAYS have the first non-comment line reading
Code:
127.0.0.1  localhost
To avoid trojan/virus contamination, set r/o on hosts using

attrib -r \windows\system32\drivers\etc\hosts

@ jobeard:
I'm on Windows 8.1, my C:\windows\system32\drivers\etc\hosts is just a template (with # preceeding all sample entries). Where can I find the ACTUAL active "hosts" equivalent file in Win8.1. I ask because I want to make mine Read-Only as you recommended to preclude malware from rewriting the host entries.

Oops; error in the above:
use to remove r/o use attrib -r \windows\system32\drivers\etc\hosts
and set r/o with attrib +r \windows\system32\drivers\etc\hosts

  • so remove the r/o and launch notepad on the hosts file
  • and remove the # comment marker on the LOCALHOST line
  • save the file
and set ro attrib -r \windows\system32\drivers\etc\hosts

I've connected to the inter net but it says unable to connect the network
If your on Windows 7 it can check your connection and tell you what's up with your connection. Same with Windows 8 they try to find a solution to your problem. Sometimes they can't.

What I would do is go into the device manager. Look for our
Network Card or WiFi Card. Select Uninstall only but not delete the driver.

Reboot the PC
Once Windows reloads it will rebuild the driver and settings.
All you have to on Wired system really nothing
WiFi you have to select NETwork connection add the passcode/password

Other things you can do....

Check the connections
Check Settings
Check make sure you have the latest driver for your PC
Check router make sure it's connected to the internet
Check for any firmware updates for your router.
Check the cable or dsl modem make sure there is not issues connecting.

Note:
Cable / Dsl modem (should be power down and power up every 3 to 6 months)
Also your Router too.

Computers can behave very strangely. This morning, after I logged on and did a quick scan, it said I am not connected the internet. I could see my modem was fine. Windows explorer said fix connection problem. Then a message came from Windows, that pink box on the screen, something about connecting to Toronto Public Library automatically. I felt a little nervous and suspicious. I clicked restart, then all was well.

In the case that this did not work, I would turn my laptop off and then logon again, this often gets rid of any glitches.

Did you do anything before this. Such as try to open an email?

I also deleted a lot of emails, just in case.

I was about to unplug my adaptor, wait 60 seconds and plug it in again.

Previously, it would say this page cannot be displayed, when you click again, it may open the page.

Or try again, not sure why this message comes up. I rarely get it. When it comes up, I do not go to that site, I try something similar.

Fundamental debugging. There's a difference between accessing the Internet (using TCP) and accessing via a browser. If the former doesn't work, then the later can not, but the former can work and the browser still fail. Here's the test.
  • launch your browser and clear the (cache, history, cookies)
  • quit the browser
  • get a command prompt; start->search->enter CMD and hit enter
  • now type these
    • ping 8.8.8.8
    • nslookup 8.8.8.8
If both of these return info and do not fail, then you have a browser problem
