I have been carefully reading a few web pages related to this topic before deciding to ask `Ubuntu`, but unfortunately now I have to come out of my hide-out and to ask for some more professional help.
The story goes like this. I have an `Asus X-551 MA Intel Quad-Core Laptop` on which I was usually running `Ubuntu` inside an `Oracle VirtualBox` virtual machine. Somehow, it never ran quick enough and sometimes I had to press a key and to wait for a few seconds until anything happened. I have tried to better configure the virtual machine, to no avail.
Eventually, after a few trial-and-error attempts, I have decided to drop the usage of the virtual machine manager and to run the real thing. What I have done has been to reinstall the `Asus Laptop` with a brand new "`Microsoft Windows 10 Home 64-Bit`" Operating System and to configure it to work as a Wi-Fi HotSpot.
The solution that I have chosen has been to install the "`Ubuntu 15.04 <<Vivid>> for Computers with Less Than Two (2) GigaBytes of Random Access Memory`" Operating System on another `Hewlett-Packard Compaq nx7300 Intel Dual-Core Laptop` and to make it wirelessly connect to the `Asus Windows` laptop. However, whatever I have tried has failed.
The best situation that I have met so far has been that `Ubuntu` wirelessly connects to `Windows`, it says that it is during the course of the connection process ("`Connecting...`"), but I do not have any proof that they are really connected.
A browser such as `Mozilla Firefox` reports that the "`Server is not found`" (Which server?) when the Wi-Fi is set in the Infrastructure mode or it plainly gets stuck in "`Connecting...`" without doing actually anything visible when the Wi-Fi is set in the Ad-Hoc mode.
I have also tried to create the Wi-Fi HotSpot on `Ubuntu` and to make `Windows` wirelessly connect to it. That time again, `Windows` was lost in "`Connecting...`".
I have been trying these tricks for Thirty-Five (35) days in a row and I am really worn-out now. I see that are other questions similar to this one, but the solutions that they have received have already been attempted without any success. This is why I have decided to write this question and maybe somebody has some clues about what is happening and which I am not yet aware about.
Of course, I would be happy to find some troubleshooting command-line tools that show what the `Ubuntu` Wi-Fi is actually doing when it is attempting to connect to `Windows`. Also, I am eager to provide whatever debugging information is needed.
This is a Home Network. The DSL Provider is a Dial-Up Broadband Provider. It allows only one connection at a time.
Currently, I am using a Switch for connecting both Laptops to the Ethernet UTP Cable that goes to the Fibre Optic Device. I am reluctant in purchasing a Wireless Router, since I am not yet fully sure that both the Wireless Chipsets are working.
I have tested the `Hewlett-Packard Laptop` using a "`Microsoft Vista Home Premium 32-Bit`" Operating System prior to the "`Ubuntu`" installation. I was very happy then that `Vista` did connect to the other `Windows`, but somehow I missed opening a web page in `Vista`, so I guess it is the same situation. I guess I was too happy that the wireless connection appeared to be working.
Both Laptops are connected also with a Ethernet UTP Cable towards the Switch. Pinging might be affected by these cables.
I remember being thoroughly happy that I have copied a very large file while I was running "`Vista`", but I can imagine that "`Vista`" might have decided on its own that - due to the size of the transfer - it was better to use the Wires rather than the Wireless Connection.
With the Wires on, with `Windows 10` connected to the DSL Provider and with `Ubuntu 15.04 Vivid` wirelessly connected to `Windows 10`, I get the following results. Please let me know if you want other permutations and combinations.
On `Windows 10`, I have a `Cygwin 64-Bit` Software Installation. This is what it reports:
Mihai@Sahaj ~
$ uname -a
CYGWIN_NT-10.0 Sahaj 2.1.0(0.287/5/3) 2015-07-14 21:28 x86_64 Cygwin
This is what I get in an `Ubuntu` Terminal Window:
varada@Ubuntu:~$ ping Sahaj

Yes, this is with the Wires on. Of course, I can try with the Wires off, but eventually I also want to use them. For Large Data Transfers I prefer to use them. I do not know yet if `Ubuntu` has Embedded Software Network Algorithms that would decide which Physical Medium to use when transferring data - as it appeared to be happening in the case of the `Vista` Software Installation.
As described before, the two Laptops are on the same network.
It appears that `Windows 10` automatically sets up its `Windows Firewall` upon its Software Installation.
Of course, I can disable it completely, but eventually I would need it on. I would require your help in configuring it for granting `Ubuntu`'s Wireless Connection.

**Test 1.** I have disconnected the DSL Provider in `Ubuntu` with the `poff` command and then connected `Windows` with a `Digi.BAT` File. `Ubuntu` has automatically and wirelessly connected itself to the `Windows10` Wi-Fi HotSpot. Afterwards, I have first disabled the `Microsoft Windows Firewall` on the _Private networks_. This category includes the `Windows10` Wi-Fi HotSpot and the `Network 3` Network that might be the Local Area Network created between the Switch and the two Laptops. `Google Chrome` has reported the "`ERR_ADDRESS_UNREACHABLE`" error while attempting to connect to the `https://mail.google.com/` Internet address.
**Test 2.** I have disabled the `Microsoft Windows Firewall` also on the _Guest or public networks_. This category included only one `Digi 7` network. `Google Chrome` has reported the "`ERR_QUIC_PROTOCOL_ERROR`" error while attempting to connect to the `https://mail.google.com/` Internet address.
**Test 3.** I have removed the Wire from `Ubuntu`. In a Command Line Terminal Window, the `ping` command has reported the following lines:
varada@Ubuntu:~$ ping Sahaj
PING Sahaj.mshome.net (192.168.137.1) 56(84) bytes of data.

Another attempt from `Google Chrome` to connect to the `https://mail.google.com/` Internet address has led to an `ERR_CONNECTION_TIMED_OUT` error.
**Test 4.** I forgot to replug the Wire in `Ubuntu` and run a `pon dsl-provider` command in order to reconnect it to the DSL Provider, obviously. An attempt to load the `http://askubuntu.com/questions/666392/why-does-not-the-wireless-connection-get-any-internet-access` Web Page inside the `Google Chrome` Web Browser has led this time to the `ERR_NAME_NOT_RESOLVED` error.
What is interesting is that, in order to connect `Ubuntu` to the DSL-Provider, I had to disconnect `Windows 10` from the DSL-Provider, after which the `Microsoft Windows Firewall` has shown another `Digi 7` active public network in its list. The `7` digit has not been chosen at random; actually, the `Microsoft Windows` Operating System has kept on incrementing its number since the first attempt to create a `Digi` Internet connection, through the `Digi 2`, `Digi 3`, and until the current `Digi 7`, while I was continually removing it and recreating it in order to configure the Wi-Fi HotSpot.
**Test 5.** Another attempt to load the `http://askubuntu.com/questions/666392/why-does-not-the-wireless-connection-get-any-internet-access` Web Page inside the `Google Chrome` Web Browser after replugging the Wire in `Ubuntu` has led to the same `ERR_NAME_NOT_RESOLVED` error.
**Test 6.** I have disconnected and then reconnected `Ubuntu` from the DSL Provider with the following commands:
varada@Ubuntu:~$ poff
varada@Ubuntu:~$ pon dsl-provider
Plugin rp-pppoe.so loaded.
This time, the `http://askubuntu.com/questions/666392/why-does-not-the-wireless-connection-get-any-internet-access` Web Page did get loaded correctly within the `Google Chrome` Web Browser. However, this has been done through the direct wired connection to the DSL Provider and not through the Wireless Connection to the `Windows10` Wi-Fi HotSpot.
**Test 7.** `Windows 10` is not yet turned on. I am running the `pon dsl-provider` and the `iwconfig` commands inside an `Ubuntu` Command Line Terminal Window:
varada@Ubuntu:~$ pon dsl-provider
Plugin rp-pppoe.so loaded.
varada@Ubuntu:~$ iwconfig

I am disconnecting `Ubuntu` from the DSL Provider with the `poff` command. Then, I am turning `Windows 10` on. It creates its own `Windows10` Wi-Fi HotSpot and `Ubuntu` automatically gets connected to it. I am running the `iwconfig` command inside the same `Ubuntu` Command Line Terminal Window:
varada@Ubuntu:~$ poff
varada@Ubuntu:~$ iwconfig

`Google Chrome` reports the "`ERR_QUIC_PROTOCOL_ERROR`" error while attempting to connect to the `https://mail.google.com/` Internet address.
These outputs do not mean much to me. Maybe they are helpful for the readers.
Also, I was looking for a command that might inspect what is happening after `Ubuntu` automatically gets connected to `Windows 10`. Is there any? I mean, besides the Web Browsers such as `Mozilla Firefox` and `Google Chrome`. Their diagnostic information does not present much interesting detail.
For instance, in the "Details" area of information for the `ERR_QUIC_PROTOCOL_ERROR` `Google Chrome` error it was explained that the `https://mail.google.com` Web Page must have been moved, which is not true. I have just opened it after directly and wiredly connecting to the DSL Provider and it is working just fine. There must be some other troubleshooting tools out there.
In case there might be some problems from within the `Microsoft Windows 10 Home 64-Bit` Operating System Side, here is how I am usually connecting to the DSL Provider from within it and how it is automatically creating the Wi-Fi HotSpot.
I am using a `Microsoft Disk Operating System` Batch File that I have called as `Digi.BAT`. Of course, I have desired that it automatically gets started upon the Operating System Start-Up. Somehow, that never happens.
The Short-Cuts that are placed inside the `Startup` Menus (both for `All Users` and for the current user) do not get started upon the Operating System Start-Up, for daunting reasons that are completely baffling me.
Therefore, I have decided to simply give up the usage of both the `Startup` Menus and to use the Old and Safe Manual Double-Click upon a Desktop Short-Cut that is pointing towards the Batch File, each time I need to connect to the DSL Provider.
This is what it is doing:
C:\WINDOWS\system32>C:\Windows\SysWOW64\RASDial.ex e Digi <UserName> <PassWord>
Connecting to Digi...
Verifying username and password...
Registering your computer on the network...
Successfully connected to Digi.
Command completed successfully.
C:\WINDOWS\system32>netsh wlan set hostednetwork mode=allow ssid=Windows10 key=<PassPhrase>
The hosted network mode has been set to allow.
The SSID of the hosted network has been successfully changed.
The user key passphrase of the hosted network has been successfully changed.
C:\WINDOWS\system32>netsh wlan start hostednetwork
The hosted network started.
C:\WINDOWS\system32>PAUSE
Press any key to continue . . .
Some more pieces of information from the `Microsoft Windows 10 Home 64-Bit` Operating System World.
Inside the "_Control Panel > All Control Panel Items > Network and Sharing Center_" Window, the following pieces of information are displayed:
View your basic network information and set up connections
View your active networks
Digi 7 Access type: Internet
Public network Connections: Digi
Windows10 Access type: Internet

**Digi 7** is the Seventh (7th) Version of the Wired Connection to the DSL Provider. It has Internet access and it is feeding **Windows10** bits and crumbles of it. Or at least it should be. I do not know yet how to test this aspect.
**Windows10** is the Wi-Fi HotSpot. It should have Internet access obtained from the above-mentioned DSL Provider Connection. It can also create a HomeGroup, but I do not know yet if that would be helpful for the `Ubuntu` World. Would it be?
**Network 3** should be the Local Area Network created by the Loop formed by the Switch and the Two (2) Laptops, Wired between themselves with Ethernet Wires. This one appears not to have Internet access and I am not interested in it having any. I just want to minimize the load on the Wireless Internet Connection that hopefully will be running soon also on `Ubuntu` and to use this Wired Connection for Large Data Transfers.
This is kind of it, regarding the loads of information that I am able to paste here from the Two (2) Worlds of `Windows 10` and `Ubuntu 15.04 Vivid`. Of course, I can go on pasting pieces of information from `Properties` Windows and from other places, but I prefer to wait for some requests. I am kind of done with investigating. This has extended with a few days the initial investigation period of Thirty-Five (35) Continuous Days.
One more thing, from within the `Ubuntu` World. I just want to make sure that there is nothing fishy among the Wi-Fi Connection Settings. These are the details of the Wireless Connection in `Ubuntu`:

`Ubuntu` Proxy Settings.
_Mozilla Firefox_
Just to make sure, I have changed the default setting from `Use system proxy settings` to `No proxy`, to no avail. `Mozilla Firefox` continues to report the following error message:
Server not found
Firefox can't find the server at start.ubuntu.com.
Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
_Google Chrome_
`Google Chrome` is trickier, as usual. He just will not give up easily. While attempting to alter the Proxy Settings, it has opened the `chrome://linux-proxy-config/` Web Page with the following pieces of information:
When running Google Chrome under a supported desktop environment, the system proxy settings will be used. However, either your system is not supported or there was a problem launching your system configuration.
But you can still configure via the command line. Please see man google-chrome-stable for more information on flags and environment variables.
While going towards the Command Line Terminal Window, I have not had any success there, either. Help does not seem to come out easily:
varada@Ubuntu:~$ /usr/bin/google-chrome-stable --help
No manual entry for google-chrome-stable
See 'man 7 undocumented' for help when manual pages are not available.
What is interesting is that `Google Chrome` keeps on shuffling its error codes when it is reporting an error. This time, it has presented the following error to the user, when the `https://mail.google.com/mail/` Web Page has been attempted to be opened:
This webpage is not available
ERR_NAME_RESOLUTION_FAILED
Hide details
The webpage at https://mail.google.com/mail/ might be temporarily down or it may have moved permanently to a new web address.
Anyway, `Mozilla Firefox` has already proven that there is no proxy set up. I have never ever set up a proxy on this machine in `Ubuntu`. This is a fresh installation, done from a `Ubuntu 15.04 Vivid` Digital Versatile Disk.
Also, I was attempting to understand Ads' logic in their request to disable a firewall only on the `Microsoft Windows 10 Home 64-Bit` machine.
Indeed, logically `Ubuntu` needs to access `Windows'` ethereal space, so it needs to cross any firewalls that `Windows` is maintaining. Now, the `Microsoft Windows Firewall` is completely disabled, on all the networks.
What if there is a need also to disable some firewalls inside the `Ubuntu` World? I have never ever set up any firewalls on this machine in `Ubuntu`. Are there any firewalls installed in `Ubuntu` by default that have to be disabled, also?
