1.1.1.1 speed cut in half over Wi-Fi

Site Feedback

Can anyone help me understand why I my internet speed is cut 50% + when using 1.1.1.1 WARP over 802.11ax on a PC running Win 11?

I am running default settings on the app and my hardware is fine.

This only occurs when 1.1.1.1 is running on Wi-Fi. Thanks

Using 1.1.1.1 has no effect on internet speed so this is likely some sort of proxy being used

A DNS server like 1.1.1.1 is used only for DNS resolution (to convert domain names to IP addresses ) and the data transfer happens directly to your IP address and not through the DNS server. I suggest to dig further to find the root cause

Uninstall CloudFlare Warp. Same thing happened to me and one of my friend. After uninstalling, the whole thing went to normal.

Do you have a cache server or is everything pointing to 1.1.1.1?

When you’re not using 1.1.1.1, which server are you using, and is your DHCP gateway pointing to it or all devices pointing to it individually?

6

What type of wired connection? What type of WiFi APs? What type of backhaul from APs to router? How many devices on that ap?

Lots of needed info

I’ve had really strange behavior from chasing dns sometimes. Sometimes clients need their dns records purged. Also, sometimes cloud flare is doing some construction.

Thanks for the reply. I’ll keep digging.

Speed not degraded over same connection when 1.1.1.1 WARP is disabled. Does not seem to be the Wi-Fi.

Thanks for the reply and the suggestion. I did the un/reinstall …no change.

ATT fiber => ATT Gateway => 2.5 GHz Ethernet backhaul => TP-Link Deco 6e AXE5400 Pro (XE75 Pro) => PC Win 11 with Intel® Wi-Fi 6E AX210 card.

4 wireless devices connected

Speed degradation ONLY occurs when 1.1.1.1 WARP is enabled. Not through the same wireless connection without WARP and not when connected via Ethernet with or without WARP.

Side note: This degradation also does not happen when using WARP across same network with iPhone iOS 17.3.

The only limiting factor is WARP on Wi-Fi with Win 11.

Thanks

When WARP is disabled you’re not using WARP, it’s just using your internet connection.

With WARP your traffic gets routed to a Cloudflare PoP, with encryption. So it will be slower, WiFi will exacerbate this slowness.

Arent you hitting a speed throttle for 1111?

14

Your PC Wi-Fi Network Card might be throttling the UDP packets from the Warp app.

You might be able to adjust this in the Settings of the card in Device Manager. Look for options called QoS or RX TX control and try turning them off. Don’t forget to write down the default values so that you can revert them.

15

Right, thanks for the feedback. Would expect speed to be degraded by 10% - 20%, but 50%+ seems excessive.

16

Thanks, I’ll give it a try.

17

You’re welcome. Thank you for the reply.

Let us know how it goes

Well, I just looked at the card settings and couldn’t find QoS or RX TX in any of the Property Settings.

I will just keep looking. I appreciate your help.

Thank you for checking.

The Settings should look something like this:

They will differ depending on the card. Also, you probably done this already, but make sure you’re on the latest driver of the card (or try an older version if there is something specific in the changelog that mentions QoS or packet/traffic shaping

20

Thanks for your help. Yup, drivers are all current and SW & FW is up to date. I looked once at the Intel settings for the card and didn’t see anything related.

I’ll check out the links you provided and just keep looking.

Again, appreciate all your input and timely response.
