How Do I Use the ip renew Command to Refresh My Network Connection? or What’s the Correct Way to Run - ProxyDrifterX - 26-01-2025

"Why Isn’t the ip renew command Working for Me?"

Hey guys, so I’ve been having some weird network issues and tried using the ip renew command to fix it. Ran it in CMD as admin, but nada—still stuck with the same IP.

Anyone else run into this? I did the usual ipconfig /release first, then ipconfig /renew, but it’s like my PC just ignores it.

Maybe my router’s being stubborn? Or could it be a DHCP thing?

Also, is there a *right* way to use the ip renew command? Like, timing or something?

Quick side note: does this even work for WiFi, or just Ethernet?

Thanks in advance! (and sorry if this is a dumb question lol)

Hey! Had the same issue last week. Turns out my router’s DHCP lease time was set way too long, so the ip renew command didn’t do squat.

Try logging into your router (usually 192.168.1.1) and check the DHCP settings. Maybe shorten the lease time or just restart the router.

Also, yeah, it works for WiFi too, but sometimes WiFi adapters can be finicky. Try disabling/re-enabling your WiFi adapter after running the command.

lol not a dumb question at all! The ip renew command can be weird sometimes.

One thing ppl forget is that some ISPs lock your IP for a while. So even if you release/renew, you might get the same one.

Try connecting to a VPN or just wait a few hours. If you’re desperate, unplug your modem for like 5 mins—old school but it works.

Bro, same. I spent HOURS on this.

Turns out my antivirus was blocking DHCP requests. Wild, right? Temporarily disabled it, ran the ip renew command again, and bam—new IP.

Also, check if your network adapter is set to DHCP and not static. Sometimes updates mess with that.

Quick tip: Run `netsh int ip reset` in CMD before trying the ip renew command again.

It resets the TCP/IP stack and often fixes weird issues like this.

If that doesn’t work, maybe your router’s DHCP pool is exhausted? Log in and see if it’s handing out IPs properly.

Honestly, the ip renew command is hit or miss.

If you’re on WiFi, try switching to Ethernet just to test. Sometimes WiFi drivers glitch out and ignore DHCP requests.

Also, `ipconfig /flushdns` might help if DNS is tangled up in the mess.

This might sound obvious, but did you run CMD as admin? The ip renew command needs admin rights to work properly.

If you did and it’s still not working, try this tool: NirSoft’s DHCPLogView. It shows DHCP server activity—super handy for debugging.

Wow, thanks for all the suggestions! Didn’t expect so many replies.

Tried the `netsh int ip reset` thing and it actually helped—got a new IP after that. Still weird that the ip renew command didn’t work alone though.

Gonna check my router’s DHCP settings next, since a few of you mentioned that. Appreciate the help!

Yo, router firmware could be the culprit. Mine was outdated and just refused to play nice with the ip renew command.

Check for updates or just factory reset the thing. Pain in the butt, but it fixed my issue.

Also, some ISPs use MAC binding—so renewing might not change your external IP.

Had this exact problem last month!

Tried everything until I realized my PC was set to a static IP in the adapter settings. Whoops.

Go to Network Settings > Adapter Options > IPv4 and make sure it’s set to "Obtain an IP automatically." Then try the ip renew command again.
