I got a new laptop a few months ago and I've had a lot of problems with my wireless internet connection (I have not tried wired).

Often, I have to disconnect and reconnect to the network, even when the computer should still be connected. The computer appears to be connected to the network, but is unable to reach any pages. People on the same network at the same time do not have similar problems. I regularly use two networks - home and school - and while home has more frequent problems, I have begun to experience the same issues on the school network.

I've also started to encounter some problems with html and css formatting display in the browser, particularly in tandem with the connection problems. Websites seem to be unable to display correctly - almost like there is no formatting. After refreshing a few times, there is no improvement, and often, I lose the connection to the site altogether. This occurs across all browsers, though I most regularly use firefox.

For example, in this text entry box, I see the alt-text instead of the pictures for "Bold," "Italic," etc.

I would really appreciate any help!

I am having the same formatting problems with the Ethernet connection. I can't speak to the disconnects yet. I will let you know if I encounter anything similar.

would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
Make sure you also indicate on the reply which tests are for what condition.

lets see the following please

ipconfig /all
Three Ping tests

------------------------------------------------------------------------
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.

This should work for all windows version, XP, Vista, W7
Hold the Windows key and press R
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.

then type CMD

then 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.

then reply here and
control key + V to paste

Type the following command
Ping google.com
Post back the results in a reply here
right click in the command prompt box
select all

Type the following command
Ping 209.183.226.152
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

In addition to what Wayne asked for ...

What firewall or security suite is, or ever was, on the system?

TCP/IP stack repair options for use with Vista and 7 and 8.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8: <Windows Logo> + x - Command Prompt(Admin)]

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

I apologize for the delay. Here is the information in a notepad attachment. The first entries are from the school wireless connection. The second from a "working" connection at home (I still was unable to reach some pages). The third is from the non-functioning connection. There was still formatting problems on sites during the working connection.

I used Kaspersky when I first got the computer, but had a lot of performance issues with it and have since removed it. I now use Avast. I will try the method you recommend and let you know the results.

Thanks so much!

My PC is a Samsung Series 7 Chronos. The driver for the network adapter says it's fully up to date, unless I'm missing something. I've yet to find an ethernet cable to connect to my router at home (working on it!), but the problem has continued to get worse, even at school. Connected (even with ethernet) I can barely open any pages the first time, sometimes having to click refresh 10 or more times to get it to display properly - and sometimes it won't display properly at all. It looks like it's struggling with css (meaning that pages have no formatting at all). If I click refresh, I often get the "Connection was Reset" error. This cycle continues on each refresh, until it occasionally comes up. Any site that uses flash or video is unable to load.

Make sure you have the latest wireless driver from the PC manufacturer's web site. If you already have the correct driver reinstall it anyhow in case the installed instance is corrupted.

I reinstalled the wireless driver - no change in performance. The issues also occur with the wired connections.

Maybe Kaspersky did not go away cleanly. Run the Removal Tool.

Maybe Avast is corrupt. Uninstall it and run the Removal Tool. You can reinstall it if desired after testing.

Wouldn't hurt to then run those post # 5 repairs again.
