"Wifi doesn't have valid IP config"

Recommended Posts

WTF does this mean and how do I make this shit go away?  I have a new laptop and every time I close it and then reopen it to start working again, it kicks me off of my home internet.  My old laptop would just reconnect to my wifi as soon as I opened it up.  This new one makes me re log in every damn time I open it.  It's driving me nuts.  Halp PLZ!

I am going to guess that you have it set up for DHCP, which automagically assigns an IP to your laptop when you log on to the network.  That is probably fucking up.  Dunno how you fix that.

You can fix the problem, most likely, by assigning a static IP to your laptop.  I will let you google to figure that out as I no longer can reliably recite the step in windows 10.

Thanks TwiceHorn.  I'm going to give that a shot.  Should I expect my laptop to blow up 10 days from now?

Nah, just make sure the IP address you give it, 192.168.1/0.x is fairly different from the other things you have on your network so there won't be a collision.  Like if you have a bunch of things with addresses where x<50, make it .128, or if a lot of addresses where x>50, make it .20.  If it causes problems, click the DHCP box again and at least it will connect.  Then maybe start over.

Static IP isn't a bad idea any time you have a connection that drops with some frequency.

The other thing you might try is checking your "sleep" settings to see if wifi is turned off.  If power isn't an issue, that might solve your problem independently.

Sleep settings might be something that is going on as well.  Sometimes it seems like it will remember the address.  Other times, it makes me reconnect.

I’d try updating your drivers first, DHCP hasn’t really changed much in 20+ years (except for the introduction of IPv6). If this is the only device doing this on the network, I doubt it’s the router (unless you installed the routers connection manager on your laptop—never do that—it’s just going to fight your built in wireless manager all the time)

That being said, routers (especially off the shelf home ones) do tend to flake out after a few years and it could be starting to go.

If you’re putting it to sleep instead of powering it off and going back and forth between wireless networks, there will be a brief period when it comes back up expecting to be on the prior network. Once it realizes that Wi-Fi connection is no longer available, it should connect to your home network automatically and request an IP. This should be pretty quick and transparent.

There could also be a malware issue.

A static IP would be a PITA if he takes it away from the house to a coffee shop.

Yeah, that is not a good fix.  It will end up causing other problems.

Static IP on a per SSID basis.  Won't have any effect except on the SSID at home.

But yeah, updating drivers and whatnot is a good plan to fix the essential DHCP issue and/or power-down of the wireless radio.

I don't windows anymore, but find static IPs to be a pretty good deal all the way around on other devices.

IP is assigned to the adapter not the network (SSID). Will need to set dns and gateway as well. Not a clean fix if he moves around. 
 

make sure ‘automatically connect’ is checked and look at the advanced powe/sleep setting for the wifi adapter

I think TwiceHorn is talking about a reserved IP from the router's IP pool that is assigned to a specific MAC address so that whenever the laptop connects to PornBreath SSID it will always get the same IP.

I usually do this with my devices like FireTV, Alex, etc...

Change your settings on your laptop to have a static IP on your local network...should be 192.168.1.xx (you can find this by going to the start menu and opening up the command prompt (just type "cmd" after you click the start button) and in the command prompt, type "ipconfig/all".  You are looking for your IPv4 for your laptop.

Change your settings within your IPv4 settings:

Insert your IPv4 address you found in the cmd prompt and for DNS server, put in 8.8.8.8 (google) and 8.8.4.4 (google secondary).

 

Give this a shot.

Yes, sorry for the confusion.
