Again following this link FIX: Wi-Fi doesn’t have a valid IP configuration and this
Followed first point again, result

No gateway shown in ipconfig /release
umable to contact your dhcp server error in wifi.

The same wifi, connected via hotspot from a phone, is working fine in 10+ devices

The last update was downloaded like in first week of July. It always used to show me a notification to install it. But I kept on ignoring it and put the laptop in sleep mode. Now after the system froze and I restarted it, that update was gone. It didn't install as there was no sign of the installation windows. Now the update history shows me the last update which was installed in June. I cannot revert it back because it has been more than 10 days. The update page shows me a new update but I cannot download and install it as I cannot connect to the internet. Where are the downloaded update files stored? Can I install the last update which was downloaded and I delayed it, manually?

Reinstalling the Windows will be a mess as it is a work laptop.

Followed these steps one last time, please check the screenshots

a. Windows 10 "ipconfig /renew" not working
Your wireless LAN adapter Wifi does have an IP address. ipconfig /renew will not renew adapters that have no connection. Every computer with wireless and an Ethernet port will have an error like this if they are not both connected.

b. I get an error "media disconnected" when I try to renew the IP address and the network connection shows as disconnected.
netsh winsock reset
netsh winsock reset catalog
netsh int ip stop
netsh int ip start

c. FIX: Wi-Fi doesn’t have a valid IP configuration
Followed the commands in step 2
netsh winsock reset
netsh int ip reset

https://imgur.com/a/G3SGDSo

Then followed this Netsh int ip reset says access denied

https://imgur.com/a/ngdASpv

And then it showed this

Then followed these commands from the same link (enabled all other adapters)
ipconfig/release
ipconfig/flushdns
ipconfig/renew

Result-

@billubakra , If it is a office laptop, why bother troubleshooting. Raise a concern, they will take the headache of fixing it or replacing it

Laptop is mine but it has some official softwares. I can get the same installed only by visiting the main office, no remote support. Moreover I will have to give a reason for this.

I think after the initial error you should have waited before trying so many fixes. I think it has messed up your windows networking configuration & registry settings.

Any way to fix the same? Did you check this post? Wi-Fi doesn't have a valid IP configuration error

Few services were stopped, few were set to manual. Enabled them all and set them all to automatic What are the bare services and components needed for WiFi?

Screenshot of the system restore, I didn't create one. It seems it was made automatically

Any tips for this?

I am so tired. Just check these one's

Hope 802.11n and 802.11bgn isn't the issue

Compare the above & you will what the problem is, your laptop is not getting any IPv4 address when set in auto mode/DHCP enabled. It is as if ipv4 isn't even there.

Yes I noticed that too.

Connected the phone to the laptop via usb cable, usb tethering that is and got this

Later on it changed to unidentified network like it does with the wifi

See this thread & confirm that ipv4 is ticked/checked in connection properties.

It is exactly like shown in that thread.

This is the registry level thing which I followed and which might have messed up things even more
*davidvielmetter.com/tricks/netsh-int-ip-reset-says-access-denied/

Edit-
Another major change which I did was set all services mentioned here to running and to automatic
*answers.microsoft.com/en-us/window...s-needed/e032fa8d-7f91-4cee-b771-2748fb81573b
Just after restarting the laptop after doing these settings the wifi showed as connected on the login page where we enter the password and after logging in, it was back to square one.

This is showing a different gateway & ip range(192.168.88.x) which is different from earlier 192.168.18.x. This is why when you manually set ipv4 net is not working because for net to work your manually entered ip & gateway must be within ip range of first three sets of dhcp server of the device you are connecting to. In case of wifi routers this range is fixed so it is easy to manually set ip but here it seems phone keeps changing this range so not possible to manually set ip to get net working. As for DHCP in your laptop, it is clearly not working correctly which is the cause of this entire issue.

I suggest to try that win 10 restore point to see if it helps but no guarantees, you may have to even reset entire windows(next best option to format & reinstall) to undo all the changes/fixes/updates.

It may depending on whether there is a proper recovery environment/oem recovery partition present in your laptop. If you do need installation DVD then get it from here:
