Wifi connected, but no internet.

Hello,
Yesterday I had my Asus laptop repaired. After that, the internet stopped working. I tried to use Ethernet cable and also my USB Wifi adapter (instead of the inbuilt one), but still couldn't access it. Here are some of my findings:

1. Windows tells that it is connected to the network, but router doesn't list my PC.
2. Router is working fine, as other devices still have internet access.
3. I tried all that 'netsh reset' blah blah, reinstalled drivers a couple of times, rebooted the laptop countless times, restarted the router and also did network reset.
4. 'ipconfig /all' shows that 'autoconfiguration ipv4 is enabled' and is being used a preferred address. (something that starts with 169.xxx.xxx.xxx)
5. Tried disabling the DHCP service on Windows, no avail. Also tried the registry hack, disabling autoconfiguration by making a DWord with 'IPAutoconfigurationEnabled' and setting it to hex value of 0.
6. Tried all of these by plugging in Ethernet from router, WAN cable directly and USB Wifi adapter.
7. 'ipconfig /renew' hangs for a while, then states that request timed out.
8. Finally, also tried setting some unused random ip manually, still, no luck.

I hope someone can help. Thanks and Regards.

Sounds like your laptop is having trouble getting DHCP. 169.xxx.xxx.xxx is what’s called an APIPA address, and is only assigned when the computer can’t get a connection to a DHCP server. Is the IP on your PC setup to auto-configure? Also, what is the DHCP range on your router?
“ipconfig /release && ipconfig /renew” may fix your problem.

Hello,
Okay, but my other devices are working fine, using the same router (laptop used to work as expected, but stopped working after I got it repaired back, battery issue). As I mentioned, I tried to switch off the autoconfiguration by using registry, and also by providing IP myself.
I don't know about DHCP range, can you explain?

ipconfig /release and ipconfig /renew results in "unable to contact your DHCP Server. Request timed out"

Thanks
