Local Wireless Network Does Not Have Valid IP Address

Please forgive me, I am not very computer literate. I need a quick fix and in laymens terms.

I was running anti-malware and anti-virus scans, installed Avast and re-started for windows updates on my aunty's Toshiba, Satellite Pro L450D-12X, Win7 Laptop, now after re-boot the lap top shows connection to router, however no access to internet. Diagnosis:

Local Wireless Network Does Not Have Valid IP Address.

This is where I'm almost useless.

I have entered IPCONFIG/ALL into CMD and can see the following:

IP Routing Enabled....:NO
WINS Proxy Enabled..:NO

Wireless LAN adapter Wireless Network Connection

Connection Specific DNS Suffix: (BLANK)
Physical Address: 70-F1-A1-53-A8-A3

Do you need more information? Is there anything obvious?

Thanks.

Try hitting up the command line, do "ipconfig /flushdns", it will flush the dns cache for you, next find your way to the wireless adapter (adapter settings in network and sharing center), right click, disable, then enable again.

Assuming your modem is currently working correctly, that should work. There is an IP address to log in to your ISPs modem in your home, where you can check the connectivity of your modem as well.

If its still no dice, try wiring your laptop to the modem itself, if theres still no net then its an ISP/modem issue and you should contact them.

Try resetting your router/modem.
Unplug it for 20 seconds then plug it back in.

This part should not be blank. This tells me that your modem or router is not connected to the internet. This part should list your ISP.

First thing to do is reset the modem/router by unplugging it for 60-seconds, then plug it back in and see if that helps.

Also this part:

DHCP Enabled: NO

Should be YES, unless whoever operates your modem/router specifically disabled it and manually assigned IP addresses to your machines.

We can get into that after you do a reset. After a reset if you still don't have wireless, plug the laptop into the router/modem directly with an ethernet cable and see if you can get internet that way. If so, then it's a wireless adapter setting we can resolve.

Might it be just the little slide button on the laptop that turns Internet on and off?

I attempted a few of the suggestions above and more from the net, no joy.

I completed system restore and all was well again.

I then preceded to install Avast (again) at which point the same problem has occurred.

Hm. Time for another restore, and I'll avoid Avast until the problem is diagnosed.

Yeah, Don't use avast. I've never had that problem with it but there must be some setting throwing it off. Use AVG instead, its also free and as far as i know has not caused any internet issues (i use it just fine on all the systems i've used/repaired ), malwarebytes is also a good thing to run as well.

Your IP address is not local. It is assigned by your ISP. That's a clue that your router is not properly talking to your ISP's equipment. If after multiple reboots and resets it still doesn't work, you might want to contact your ISP.

Looks to me like you're missing a "1" in your gateway address - typically 192.168.1.1
Other than that DHCP=YES seems most likely correct as well.

IPv4 Address: 192:168:10(preferred)


This looks wrong...you are missing a set.

It should be something like 192.168.1.0....if gateway is 192.168.1.1


Also...DHCP enabled...YES....

Likewise...on your LAN adapter (local area network), be sure to have "obtain IP address automatically" both for your local IP and DNS.


I suspect that you have IP address entered manually...
