Does the router issue an IP address from the range 169.254?

Question

Computer networks

The router is some kind of asus, I don’t remember. I only remember that it can work at 20MHz and at 40MHz. All devices are connected to it through the air without problems except for one asus n56vj laptop. It connects to Wi-Fi but gets the address for some reason 192.254. Sometimes gets the correct address i.e. 192.168.1.... but still no internet. It appears in the dhcp list, but does not ping either the gateway or other network members. What he did:
Reflashed the
router Changed the router
Reset the router settings
Deleted and reinstalled firewood on Wi-Fi
Cleaned viruses
Cleaned malware
Tried to zip the IP address on the poppy with nails, and nothing is assigned 169.254 The address changed
encryption types. (initially they did not match)
Chopped off the firewall on the router and in Windows (Windows, by the way, fortochnaya 8.1)
Removed the antivirus (there was a node)
dhcp client works properly, because the wired connection works fine, and the usb-wifi also works properly
Windu did not reinstall
The only thing I forgot to check is So this is to try to remove the password protection from the router, maybe vpa2 interferes with the laptop. Another option is to change the module, then the question is, which module is suitable instead of the original one? If anyone has any ideas, please share!

Answer 1

Does the router issue an IP address from the range 169.254?

It's impossible! This doesn't happen.
The computer assigns this address to itself if it cannot obtain an address via DHCP.
Perhaps the DHCP server on the network is not working.
If there is no desire to understand - just enter the IP address manually.

Answer 2

First of all, I would check the supported waffle standard for all devices that do not work ( https://ru.wikipedia.org/wiki/IEEE_802.11).

Answer 3

Check the "DHCP-Client" service and see the Windows logs accordingly.

Answer 4

as already mentioned above, check the DHCP-Client, reinstall the drivers for the adapter and the software for it. Try usb wifi. If the problem with the adapter works with the whistle, most likely it can die,

Answer 5

For my part, I consider it important to check the laptop for a "pristine clean OS". To do this, I recommend downloading the latest build of AdminPE, burning it to a USB flash drive or DVD, then starting from external media and, thanks to the preinstalled network drivers, try to work with the network in this system. In any case, as far as I know and from my experience, there is nothing better in finding the culprits among several devices than running default systems on them if possible.
PS: I once diagnosed the dead USB ports of the computer, I thought that the hardware had died. But no, a clean assembly of the system showed their full functioning.
