Changed Router Firmware and password, now laptop won't connect
Can anyone help?

My son decided to update our router firmware, together with this the password was changed. My computer which hosts the Internet connection works fine, all other laptops have now been connected successfully after simply changing the password. However my wifes laptop won't play ball. It is a Samsung R510, with Vista Home Premium OS. It worked fine prior to updating the firmware. I have been through the process of changing the password and have the correct security encryption in place, exactly the same process as with the other laptops. It then says successfully connected, but shows in the bottom right of the screen, Unidentified network access local only and will not connect when the browser is opened. I have tried to diagnose but the usual windows prompt to reboot both modem and router has no effect. I have set it to private, as advised elsewhere, I have switched the firewall off and removed security software, all to no avail.

From another post in this forum I tried the command prompt, then ipconfig/renew. The result of that was the following message:

An error occurred while renewing interface Wireless Connection: unable to contact your DHCP server. Request has timed out. No operation can be performed on Local Area Connection while it has media disconnected.

Not sure if that information helps anybody. So any help much appreciated. Let me stress that no changes were made to the laptop at all, it is simply not connecting following the firmware update and password change. All other computers, and phones, 6 in total, are all working fine from simply changing the password.

Any help please, lots of head scratching here. I have tried to provide as much information as I can, if you need any more then please ask and I'll do my best to provide it.

Thank You

can we see an ipconfig /all and also a device manager screen shot from the faulty PC

have you tried with no security on the wireless router - if not - try that
have you connected the laptop to the router by cable and see if that works - if not tried - try that

what security suite/firewall are you running or ever had a trial version on the pc like - norton, mcafee etc

------------------------------------------------------------------------
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 results here

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

Hold the Windows key and press R, 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 to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste
------------------------------------------------------------------------


------------------------------------------------------------------------
Device Manager
Post back the results in device manager
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
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.

windows key and pause Key should open to allow device manager to be seen on laptops may need to use windows key + FN key + Pause Key
if not then

Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
windows 7
start > control panel> System and Security> Device Manager

network adaptors, click on the + > post back the devices listed there
are there any ! ? or X


post a screen shot of the device manager - network adapters

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here

ipconfig information
Hope I've done this right, this is the Ipconfig you asked for, not sure why the error message at the beginning,


Error: unrecognized or incomplete command line.

USAGE:
ipconfig [/allcompartments] [/? | /all |
/renew [adapter] | /release [adapter] |
/renew6 [adapter] | /release6 [adapter] |
/flushdns | /displaydns | /registerdns |
/showclassid adapter |
/setclassid adapter [classid] ]

where
adapter Connection name
(wildcard characters * and ? allowed, see examples)

Options:
/? Display this help message
/all Display full configuration information.
/allcompartments Display information for all compartments.
/release Release the IPv4 address for the specified adapter.
/release6 Release the IPv6 address for the specified adapter.
/renew Renew the IPv4 address for the specified adapter.
/renew6 Renew the IPv6 address for the specified adapter.
/flushdns Purges the DNS Resolver cache.
/registerdns Refreshes all DHCP leases and re-registers DNS names
/displaydns Display the contents of the DNS Resolver Cache.
/showclassid Displays all the dhcp class IDs allowed for adapter.
/setclassid Modifies the dhcp class id.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid, if no ClassId is specified, then the ClassId is removed.

Examples:
> ipconfig ... Show information
> ipconfig /all ... Show detailed information
> ipconfig /renew ... renew all adapters
> ipconfig /renew EL* ... renew any connection that has its
name starting with EL
> ipconfig /release *Con* ... release all matching connections,
eg. "Local Area Connection 1" or
"Local Area Connection 2"
> ipconfig /allcompartments ... Show information about all
compartments
> ipconfig /allcompartments /all ... Show detailed information about all
compartments

Atheros AR5007EG this is a problem adapter and has been found to stop working for no reason OR will only work with certain router
It would appear the firmware update has made it not want to work with the adapter

as a test
try removing the security on the wireless router and it should now connect

here are some suggestion found to work over the last year or so trying to fix this particular adapter

I would hope a new driver from the samsung site would work now - as i say this has been an issue for a year or so -
you should find the driver here

Atheros Wireless Adapter - AR5007EG & AR5007
We have recently been seeing a lot of problems with the above adapter over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that
works or does not work.


Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.
Toshiba - update has worked for some PCs
HP The latest HP Atheros driver dated Sept 2010 has fixed the issue - so check the driver date, However, that does NOT apply to all HPs / Compaqs machines
- the poster did an online scan for driver updates on the HP website here HP Product Detection which resulted in a solution. Solved: Can't connect to internet wirelessly - Atheros AR5007 Wifi through Clear Comm - Tech Support Guy Forums

If you can post the Make and EXACT model of your PC here, along with the windows version you have and we will see if we can find the driver and will post a link as a reply here.

--- 3) On one occasion re-setting the router back to factory default and re-configuring the router settings has resolved the issue

--- 4) A few posters here with the same issue have found that the driver from this site ATHEROS drivers for Microsoft Windows resolved the issue
Threads are here
Solved: Public Network - Access: Local Only (Please help!) - Tech Support Guy Forums
Solved: NetGear WNDR3700 Incompatibilty W/ Atheros AR5700 - Tech Support Guy Forums
Solved: Local connection only when connected to secured wirless - Tech Support Guy Forums
Solved: Unidentified Network - Tech Support Guy Forums
Unidentified Network


I do NOT know anything about the site mentioned ATHEROS drivers for Microsoft Windows However, a number of forum members have now successfully used the site to update the driver

However, if you do decide to try the driver, Please let us know the outcome

Direct link to the drivers are below
You only need to click on the green download button labelled " click to download " and wait, the file will download - you do not need to click on any other buttons to get the download started

AR5007
Vista 32 Bit
Drivers for Atheros AR5007 and Windows Vista
Although this driver has shown up in BSODs (Blue Screen Of Death) on Vista SP2 systems, usually conflicting with updated Vista OS drivers like netio.sys, tcpip.sys and other networking related drivers.

AR5007EG
Vista 32 Bit
Drivers for Atheros AR5007EG and Windows Vista

Drivers for other windows operating system
http://www.atheros.cz/atheros-wireless-drivers.php

Assuming that after all the above the wireless still does not connect to the internet, all I can suggest is to use wireless security of WEP or to get an external USB wireless card.

You might also bug your laptop's tech support about the problem--maybe people can put pressure on Atheros to find a fix.
