I found this online some time ago and I think it's great for remembering wireless protocols. 802.11 - it has only 2 1’s with no letters, so it’s all “2’s”, 2.4 GHz, 2 Mbps 802.11a - "advanced" band 5 GHz, "adequate" speed 54 Mbps. 802.11b - “bad everything”. 2.4 GHz is slower than 5 GHz so it’s the "bad band", and 11 Mbps is “bad speed” cause it’s not much of an improvement from 802.”11” 802.11g - the “OG” band 2.4 GHz, "grim" speed 54 Mbps 802.11n - 2.4 GHz “n” 5 GHz, "new" speed 600 Mbps 802.11ac - "Advanced (a)" band 5 GHz, "Commendable (c)" speed 6.93 Gbps 802.11ax - "All (a)" bands, 2.4 / 5 / 6 GHz, "Xtreme (x)" speed 4 * 6.93 Gbps. I remember that it's "4 * 802.11ac" by the X having 4 points.

Guys, explain FHRPs to me. What do they do and what problem do they solve? Tagging you so you know you’re the ones I’m calling on 🤭 @Abdullah Mojumder @Enrico Pagani @Dan Ben @Aditya Jha @Sidiki Coulibaly @Ademola Onibokun @Lippo Lupo @Yaroslav Yatsyshen @Merlin W @Efrem Vargiu @Nabeel Shahzad @Didrika B. @Junior Djramedo

Guys, you are studying Spanning Tree Protocol so much, but why do we as network engineers care about it? Why do we actually need Spanning Tree? Explain it to the community as if we were all 6-year-olds and our lives depended on understanding the purpose of Spanning Tree. 👇

A couple of guys reached out to me on reddit asking where do I accessed Neil's flashcards. I got them after purchasing his udemy course but I'm not really sure whether you can get them publicly online. So whoever needs revisions these are great ! They are very precise and up to date should come handy.

Hey guys, I was on Reddit again and I found a link to all Jeremy's IT Lab notes in PDF format if anyone wants them. I wrote my own, but since this is in PDF, I can always keep the notes with me when I am not home. https://drive.google.com/uc?export=download&id=1xB3W0yHjSJp6D63bpiqDnHkkces9Pq_N
