Hey everyone 👋 I was inactive the past week because I was sick and at the same time very busy helping my wife opening up her own local store. Now I’m back and will provide you with study material as usual! So let’s vote for the next lab topics 👇

This was a very good question. I was stuck thinking it would increment the TTL and forward the pack or drop the packet. But if it increments the packet, that would put it at 0, so it must drop it because the next router wouldn't accept it (those are my thoughts). But in all the years, this is the first time I ever saw this question asked. Thanks Vith for sharing this one.

Remembering Wireless Protocols

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.

The speed is limited to your ISP as well. Here I have 1200Mbps, but I usually get about 900. When it's congested it slows down just a tad.
