Except that wireless is half-duplex and uses CSMA/CA vs wired's full-duplex CSMA/CD, thus wireless is slower than wired is.

Layman's Explanation: Wireless sends information and then receives it, like two people having a conversation, one talks while the other listens. That's half-duplex. As for CSMA/CA vs CSMA/DA, CA avoids collisions and DA Detects them. Both handle it differently. Avoiding is much harder work than Detecting it is, in other words, you spend more effort avoiding doing the work your boss wants to give you, than if you just did the work and be done with it, you'd expend less energy. Not the best example, I know, but it's a very generalized explanation.

Wireless is open to MITM attack vectors, and while wired is too, it's much less so because you can do port locking and there's no roaming.
Layman's Explanation: MITM attack is Main In The Middle attack. Basically, someone puts a WAP (Wireless Access Point) in between you and a legitimate WAP, and thus they can do things like capture cookies from your web browser and login to sites as you, they can sniff (capture) your data packets with tools like Wireshark and Etherape, and a whole host of other things as well. Normally wireless works like this, You > WAP > Router/ISP but in a MITM it's You > MITM WAP > Legit WAP > Router/ISP. The MITM is acting as a pass-through. You think your connected to a legit WAP, but you're not, well, at least not directly connected like you think you are.

Now let's say you ARE connected to a legit WAP and then you move 150 feet down the hallway to another room around the corner, your wireless connection will roam and you could connect to a MITM WAP from a legit one as you roam. This same technology is how wireless works with jumping cell towers (basically speaking... different protocols and technology is in use, but the roaming concept is the same, thus my point).

With a wired connection, it goes from your PC to the wall jack via stranded CAT5e cable. From the wall jack inside the wall it uses single core CAT5e or CAT6 to go to the switch port in a locked server room and then out to the router from there. There may be a proxy, firewall or other devices in line, but that's the simplest path.

With wired or wireless, you get an asynchronous connection (meaning it's faster one direction (usually down) than the other (usually up), but again there's the duplexing to consider. Also, once cable gets DOCIS 3 with the channel bonding, that will free up a lot of channels for bandwidth. Right now cable companies send you everything, even if you don't receive it, under DOCIS 3 or 3.1, that will change and you'll only receive the channel you're watching, thus freeing up channels for other use. Cable companies never really focused on Internet access, only programming. It's still a new area for them to play catch up.

So is Clear and wireless "good"? To he average person, sure. To those who work in technology and understand it? No. It's not as fast, secure or stable as wired is,

By the way, if people go to Starbucks and their network name is MSHOME or WORKGROUP, or if their home wireles router is named linksys or netgear, or if their laptop is configured to auto connect to wireless networks, or if people don't really understand the technology they own and use, they may want to change that too.

So Comcast is going to ban "firearms related advertising" while at the same time promoting garbage on the History channel about wanna be soldiers playing games with all kinds of weaponry. The name of this new "reality" show escapes me at the moment, but I will NOT be watching it. I'd drop Comcast, but it's the only game in town.
