IPv4 address issues

I'm having difficulties connecting my laptop to the internet. It's a new purchase with a clean install of windows 10, with the hideous number of windows updates done. (seriously? MS hasn't figured out how to restart specific packages yet? 0.o it's been that way for decades in most flavors of linux).

the WiFi interface itself is saying either 'unknown network, no internet' or 'secured, no internet'. The Ethernet also does this when connected directly into the modem/router.

Further, all other devices work on my home network, no problems, and it's clearly functioning normally.

I suspect the problem exists in the fact that my wifi router is older and not able to use IPv6, and for whatever reason, the laptop isn't getting an IPv4 address off the network like it should.

network settings are set to default... and yes, that includes automatically being assigned DHCP addresses.

Fixes I have tried with no success:

-turning off IPv6 through the network adapter settings. (not registry key- some 'solutions' indicate that.) Shows no difference. Done on both ethernet and wireless.

-reinstalling drivers (won't be allowed, so maybe it's still the drivers. Removing the device does *nothing* to purge the old drivers (even if I toggle the 'delete drivers' option that came up...once...). On restart, it reinstalled the probably-corrupted drivers anyhow. Then just hitting the setup.exe for the drivers gives zero options to ignore driver version. (I get that they're making windows for morons, but really???)

-changing the wireless mode. (a/b/g/n options. not sure what that was supposed to do but hey, I'm desperate.)

Hi,
Could you please provide the model of your laptop, WiFi card and the driver version, in the meantime please try the fixes in this link except method 3(I would suggest installing drivers manually):https://www.drivethelife.com/windows-10/fix-windows-10-unidentified-network-problem.html

Sorry, thought I had included the model number. its the nitro v (515-42) the wifi card is a qualcom atheros QCA61c4a wireless, the ethernet is a realtek card. not sure what model number.

working on the link you provided. THANKS.

Hi,
No problem, give this also a try:

Okay. thanks for the link. I've also tried 'reseting' and restarting per MS's recomendation. It reinstalled the same drivers, so meh.

Trolling through the various methods:

method 1: Network utilities verified hardware is working and configured properly. Several other devices, both wired and wireless, are working as normal.

method 2:not sure what airplane mode is going to do that simply cycling on and off the wifi isn't. at least, not in this instance. Still... tried it. No change.

method 3:This is a new, fresh out of the box laptop. First thing I did/tried to do was update everything. everything is up to date now (accessed through a public wifi at work. IPv6 address assigned.) side note- this laptop will be accessing proprietary data. I'm not going to put a 3rd party app that modifies/scans drivers. I also attempted using acer-provided (downloaded from here) drivers. but the DL drivers here are older and windows will NOT allow them to be installed. (seriously.)

method 4: there's no conflicting devices to disable.

method 5:Trouble shooter tells me what I already know. It's not getting an IP address assigned. Because it's looking for an IPv6 address on a router that is too old for IPv6, and it's not accepting IPv4 addresses. Actually, it's not telling me that much. Half the time its being a retard and recomending I check the internet. the other half it's just telling me it has no assigned IP.

Method 6: disabled/reinabled. No change.

method 7: switching to a manual DNS server is not a permanent option. This is a work laptop, I'll be using it on multiple networks. Including networks that don't have default settings. Even so, tried it as a short term fix. nothing. ipconfig /renew yields fails from being disconnected.

ipconfig /all reveals the IPv4 is apparently assigned to the default trash address 169.-.- indicating it's some how not talking to the router through IPv4.

Okay, also thank you for the second video. having watched that, yeah. I'm not getting an IP address assigned. For some reason my laptop is not looking for, or receiving IPv4 addresses, and only looking for IPv6. (which is why it connects no problem at work.)

My router is only able to do IPv4. (old. I know. but that's the way it is.) Also, I *cannot* assign a dedicated IP address. I'll be using this laptop across multiple networks. That means it needs to be automatically assigned by the network- which is how it was set up by default.

Give this a try, go to BIOS settings by pressing F2 button at start, move to Main tab, press F9 button to restore the settings to default, then click F10 to save and exit, it could be a glitch in BIOS settings.
