Good that got Netgear support to fix the immediate problem. For others who land on this thread later, here’s a compact, practical checklist that expands on ’s and ’s suggestions and helps isolate common causes on ThinkPad notebooks.

  • Quick isolation: power-cycle the router/modem and the laptop; try a wired connection to the same router to confirm whether DHCP is working for other devices; toggle the ThinkPad’s hardware wireless switch or Fn‑key radio control (these often disable the radio at the hardware level).
  • Router checks: log into the router admin page and confirm the DHCP server is enabled, the address pool isn’t exhausted, and MAC filtering or access control lists aren’t blocking the laptop. Look at the router’s client list/logs for your laptop’s MAC.
  • Windows-side checks: disable any vendor wireless utility or third‑party firewall/antivirus temporarily (they can block DHCP traffic). Uninstall or update the wireless adapter driver from Device Manager and remove any stale wireless profiles that might use the wrong encryption. The adapter’s power‑management settings can also sleep the radio—turn that off.

Reset the Windows network stack (then reboot):

netsh winsock reset
netsh int ip reset

If DHCP still fails, try assigning a temporary static IP within the router’s LAN range (use an unused address on the same subnet, set the router as gateway and add DNS) to confirm basic connectivity. If that works, the problem is DHCP-specific at the router or with the laptop’s DHCP client. If nothing helps, collect router logs and the laptop’s network diagnostics, and contact the router vendor with those details.

Practical note: the disable/enable adapter trick from is a fast first step, but combine it with the router checks above to find the root cause rather than relying on a one-off reconnect.

make sure the DHCP server is up and running

Member Avatar for dami06

The DHCP is enabled. I checked it under ipconfig/all in the command prompt. Please what else could be wrong with it

Member Avatar for DimaYasny

the DHCP server is not in your PC, it is on another machine, possibly a router

I'm using netgar and everything is working fine because the internet is working fine on another laptop but not on the IBM thinkpad

put the results of ipconfig /all in here

IP looks strange, not something a router will give out. and what about the wired connection, do you use it?

Member Avatar for santoscardenas

If you are trying to renew the IP on the wireless, just go to "My Network Places" right-click, and go to properties. Select the wireless connection icon, right-click and select disable. after its disabled, right-click again and select enable.
