You definitely have some of the best videos I have come across on OpenWRT.

[francescopocci]

Hey man, are you a teacher?! This video is the one that I was looking for and Your explanations are GREAT! OpenWrt is not that simple (and the wiki is confusing IMO) but you make things easier. Keep it up, please !

[lteoot]

Wow.. just incredible the clear, simple, and well detailed explainations you give to whip a segmented home network that probably will apply to the 99% of us out here... big fan and love what your doing!

[ColinReddig]

This is such an incredibly helpful video for newcomers to OpenWRT. Very high quality an informative. The way you explain things is so clear. Thank you!

[goppinaththurairajah]

Simple and effective explanation by covering the audience from beginners to advanced.

[LeoGitarzysta]

Kudos. Very informative video and without substantive errors on the topic, and showing the proper understanding of underlying mechanisms This is the proper way in which OpenWrt configuration should be explained.

After many hours of struggling with OpenWRT in the past months, finally came back to it and re-watched your series on OpenWRT, I think I have a handle on it now (which probably means I don't understand it 🙂 ), and now have Guest Access points and its all working its a steep learning curve with Openwrt, didn't get the fundamental building blocks of "interfaces" and how they relate to the router, to physicall ports and other network dark arts, but its now making much more sense. Many thanks Marc....

Thanks, this was really helpful. Your explanations gave me enough info to be able to tailor everything to my own needs without being completely lost. The screens shown are a little out of date for the latest version of OpenWrt but are still quite usable.

[jaromanda]

OMG! Your explanation of the firewall in OpenWRT was the final piece in the puzzle for me - it all clicked with this video, thank you

[PankajSharma-irfb]

Best set up video for beginner to achieve a perfect network settings with full understanding of how the os does this.

[colinnich]

Just the video I needed - can't wait for the VLAN to 2nd access point episode! I've just set up a two OpenWRT router system because of your fast roaming video.

[Danacus]

You are doing exactly what I am trying to do. Thank you for the clear explanation!

[ClintonWBlackmore]

I've been needing this video for months. I've found OpenWRT to be so confusing. This is explaining exactly what I wanted to know. Thank you so much.

[crazylio]

This is such an awsome video! I am just getting started with OpenWRT and LUCI and I have been looking for this kind of video for weeks. Love the level of detail and the screen captures.

[sytd]

great video, clear and amazingly helpful. in openwrt 22.03.5, the "bridge interfaces" checkbox in the "add new interface" menu is no longer there, is there something i need to do in this version to acheive the same thing?

[cau]

This is the best channel on Openwrt and some more, please continue !

[Christian_Ky]

To be honest, brilliant!
It's not only that you explain it simple and brilliant, in addition you really lern!

[bradkaral]

Darn, your videos are so clear and well-presented.

[stbhgp]

i'm from indonesia, i didnt speak english well, need more focus to understand what the meaning of
so i've watch this video again and again

great job, thank for your explaining video

[henning]

Another great video.
I've been reading documentation for days to find out what and how I have to configure a OpenWrt router. Just like Franceso Pocci, I find the OpenWrt documentary very confusing. Only when you understand how it works can you understand it :(
And like Colin Nicholson, I'm excited about the expansion to include VLANs.

You have a talent for explaining complicated things simply. Great. And that with the proverbial "German thoroughness"

Last night I managed to flash my Archer C7 on OpenWrt. Had the latest TP-Link firmware and unfortunately only worked with TFTP. It took me a long time to find out that media sensing was the problem to get TFTP to work. :(
I'm going to do the configuration right now. I will try myself to get VLAN working too...

Many greetings from Braunschweig to Berlin
