DHCP lease renews every 30 seconds

Open | Networking

I've been having issues on all my devices for a while now. Every so often, I'll click on a link and the page won't load (network disconnected error). Reloading loads the page either immediately or after a couple seconds of spamming ctrl+R.

I was browsing through my router settings today, and all my devices showed a Lease Expire Time of just under 24 hours. It looks like my phone takes a couple minutes before it's renewed and back at 24h, while my PC consistently renews every 30 seconds. My laptop's lease hasn't been renewed since last night.

Changing the lease duration doesn't affect the issue. Rebooting router / PC doesn't help. I tried exiting any and all processes that might affect my network, but alas. Nothing's helped in the slightest.

Really hope you guys can shed some light on this issue. It's driving me mad!

  1. Open command prompt
  2. Type ipconfig /release
  3. Press Enter
  4. Let it do it's thing, might take a moment.
  5. When it's done, type ipconfig /renew
  6. Press Enter.
  7. Let it do it's thing, might take a moment.
  8. Should be good from there.

Thank you. But did not solve the lease issue.

Let's get weirder with things.

On your laptop, right-click on the network and click "Forget this network."

Then re-join.

Set your pc up with a static address and eliminate DHCP on it

Any downsides to doing this? And what about my phone?

Assuming it's a desktop that doesn't move, nothing.

If it's a mobile laptop you'll need to undo it when you are on a different network.

That being said renewing a DHCP lease shouldn't be an issue.

You might have a DNS issue.

This sounds very much like a problem on your PC and not the router.

Try updating the network card drivers on the PC.

The problem also occurs on the macbook, so it must be the router.
