Solved: Windows 8 and wifi connection problem
I am having trouble connecting my new Toshiba Satellite p875-31p running Windows 8 to my wireless internet connection.
the laptop came new with windows 8 it has not been upgraded to it.
It connects fine using the Ethernet. There are 3 other laptops running win 7 starter, win 7 ultimate, and xp all of which are able to connect wirelessly without problems.

I have checked the device manager and there are no conflicting devices or errors on the network adapters

When i run windows diagnostics i get the following error

wifi does not have a valid ip.


i have checked my netgear dgn1000 router and all attached devices are given there own ip addresses


I have tried (as admin)

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)

the result of which is this:

resetting global, ok!
resetting Neighbor, ok!
resetting path, ok!
resetting rout, ok!
resetting failed.
access denied.

After a restart i am still unable to connect.I have tried a system restore to no avail!


Below is the results of my ipconfig /all

Make sure you have the latest wireless driver from the laptop manufacturer's web site.

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.

If still no wireless connection after the above ...

Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 8 or 7 or Vista I prefer to use the built-in Snipping Tool.

The "access denied" is worrisome.

In Device Manager uninstall the wireless adapter; then restart the PC and let Windows discover the adapter and reinstall the drive. Then try the repairs again.

Disable encryption on the router and try to connect. If that succeeds then try WPA-PSK (not WPA2).

Hi,

I changed the settings to what you said and now no computers can connect wirelessly to the router. I cant change the settings back as they no longer show up at all in the wireless tab!

Just noticed something interesting...

When i tried to change the settings back it was through my computer with an ethernet cable and i could not see the wireless setting at all to reset them. When i tried via another computer using the ethernet cable it was able to view the settings and change them back to what they were. ... dont know if this is any help, i just thought it was interesting that my computer doesn't even recognise that there are wireless settings!

The problem in my opinion may well be the modem/router

That Intel Centrino 2230N wireless adapter, has been found to require in many cases an update to the router firmware

Referring to your last, reset the router there is more than likely a reset button, that requires usually a ball point pen or similar to press the reset to defaults

Your last was not visible when I typed this what make is the modem router OK found it now Netgear leave it with me I will post shortly

Try a firmware update to the router
http://downloadcenter.netgear.com/other/

re this firmware update please pay attention to this
Click Yes to check for new firmware (recommended). The wireless-N modem router



automatically checks the NETGEAR database for a new firmware image file. If no new

firmware version is available, the message “No New Firmware Version Available” displays.

(If you select “No,” you can check for new firmware later; see the online User Manual).


2. If new firmware is available, click Yes, and the router automatically upgrades itself with the



latest firmware.

Do not try to go online, turn off the router, shut down the computer, or do

anything else to the router until the router finishes restarting and the Ready light

has stopped blinking for several seconds

The problem computer could not connect even with encryption disabled? Make sure you are not using MAC Address filtering on the router to lock yourself out.

Not sure what the problem was but it has been fixed.

Tried Macboatmaster's advice which resulted in none of the laptops being able to connect via wifi or ethernet. I think the connection may have been interrupted part way and scrambled it a bit. After some fiddling with the routers settings I decided to reset it to its factory settings. Now all the computers are working fine

Thanks for your time and help .

Hopefully it is not a temporary fix!
