Since I bought this new pc I've been trying to connect to the internet but I couldn't. I have a personal wireless network to which i can connect with other devices but this new machine just can't. In the first place it can't even connect to it (sometimes it doesn't even see it) and when it can i can't seem to be able to surf the web without problems (really slow). this new pc has a ipv6 while my laptop is a ipv4, maybe there's some kind of conflict with the router? I can show you the ipconfig/all if it can be of some help. thanks

can we see ipconfig /all and an inSSIDer screen shot with the network name

is this a desktop or laptop PC

------------------------------------------------------------------------
ipconfig /all

If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

For Windows 8
To open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.​

For windows version, XP, Vista, W7
Hold the Windows key and press R

Now type CMD

Now press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):​

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.

is this a desktop or laptop ?
so you have windows 7 and its not obtaining a ip address

if you connect to the router with a cable does it work

can you move closer to the router and see if you can connect

also
------------------------------------------------------------------------

Remove the wireless security
As your wireless security enabled?
Log into the router and remove the wireless security - now see if it will connect.
if it does - log back into the router and try with the wireless security enabled again

it's a desktop computer, i tried to connect it to the router but it didn't do better than wireless (could only load like yt or google but nothing more. in both cases, cable or not). the guys from the shop told me that there it worked fine with their wifi, so maybe it's something in my network
