Platform-Independent Technical Gibberings - hardware and "Internet"

I'll prattle on some more.

There are various layers to networking. At the bottom is the physical layer.

Ethernet is an example of a physical network design. Ethernet started off pretty badly in it's "10 base 2" incarnation, a pretty shoddy network design run over a single shielded co-axial wire that was a nightmare to keep working. Thankfully we stopped all that in around 1998 or something and decided to use "Twisted Pair" structured cabling. Modern day wired ethernet runs at 100 or 1000 Mbps which is very fast, and uses "CAT-5" cabling which is the wires that have plugs that look a bit like phone sockets but are too big to be phone sockets. Those connectors are called RJ45.

Modern wIred gigabit ethernet is very smoothly running affair, you have a central device called a "switch" which is a box with loads of RJ45 sockets on it, and every networked device connects via a CAT5 cable to the switch. There you have it, a LAN. A local area network.



For devices on a local area network to communicate they need to have unique physical addresses. These are called MAC addresses. Media Access Control. MAC. These addresses look like this:

00:1a:13:2e:58:d5

Every device on a local area network (LAN) needs a unique MAC address, so they can talk to other devices on the LAN. A local area network is local because it doesn't go beyond your premises. So if you have an ethernet switch and a number of devices connected to it via CAT5 cables, they can all talk to each other. But they can't talk to devices that aren't connected to that switch. They can't see the outside world.

To get to the outside world, america invented the internet. It is a layer on top of the physical network. I have a an ethernet LAN in my home, but I'm also connected to the internet by virtue of TCP/IP. Actually that's a shorthand, because there is also UDP which sits next to TCP, but people are really fucking lazy so they just call it TCP/IP. But the really good bit is the IP. Internet Protocol. It lets devices on one LAN talk to devices on other LANs. And it does so using things called Routers.

IP allocates every computer an address like 123.23.1.32 and we've had this discussion before so I'll not go into much more detail.


So someone decided wires were too ugly and complicated, they were right but wires also work very well indeed! I love wires, because they work, and they are fast. But everyone wants wireless because it's "magic" and you don't need a wire stretching from your router to your laptop in your bed while you're having a wank. Wireless is really all about making wanking easier.


So, they got rid of wires and the called it WiFi or Wireless Ethernet. Or Wireless network. Wanker Friendly.

What makes you think they're using it?

Basically, you need to login to your router's admin pages and set up a WPA passphrase.

That normally means going to 192.168.0.1 in a web browser, putting in the admin password, finding "Wireless security", enabling it, setting the passphrase, remembering it and saving the changes. Then you'll need to put the passphrase into your computer.
 
Signals do drop low without any need for neighbour's involvement!

Wireless networks are shit. My expensive router (£200+) is three metres away from my bed, but because there is a brick wall between my bed and the router, the signal drops to 1 bar.

And no I'm not constantly wanking in bed! I check BL too. Actually I very rarely masturbate. Why is the thread going in this direction :?

To get back on course, you could try just changing the "channel" that your wireless network operates on. If there are other networks using the same channel, performance will suffer. And I don't mean staying hard!
 
BT home hub 3 already has a WPA passphrase so there is no need to set that.

It also automatically changes the channel if there is interference so that won't help.

Try knocking down your walls! Or easier, put the router in the room you are sitting in.

If you are always sitting at a desk, there is no substitute for an ethernet CAT-5 cable between the router (BT home hub is a wireless router) and your computer. It is the best solution. Wireless is shit.
 
do this look real ?

.zip file... I got loads from banks I have accounts with like from [email protected] someone has withdrawn 4,356 from your acc please download this file lol aye well good for them
 
Resolving host is where you type in a name like www.bluelight.ru, the computer says "Name's no good, need an IP address." Looks at it's DNS config, finds a DNS server (aka nameserver). Which should be the router, as issued by DHCP. Sends a message to the router "what is the IP address for www.bluelight.ru". Router looks at it's DNS config, finds a DNS server, which should be your ISP's name server, sense a message "what is....". ISP's etc etc . Someone who knows what they're talking about says "I know that, it's 93.189.134.5 and the message is passed all the way back to your computer/tablet/phone, which then stops saying "resolving host", wraps up an HTTP request and addresses it to 93.189.134.5.

Anything which stops any part of the bit up to it stopp ing saying "resolving host" will mean it keeps saying "resolving host". Except for other sorts of broken things like someone sending back a NXDOMAIN reply which means "there is no wwz.bluelight.ru" cos you typed the wrong fucking name. Then you'll get a message "Host not found".

Would changing the channel help with my problem? The fact that there's about 15 other routers within range makes me think it might.

When I'm saying it won't load web pages, what it does is hang on "resolving host", dunno if that gives anyone a clue what's wrong?
Click to expand...

If your router/devices have the required hardware, switch to 5ghz, or changing the channel will help loads.
 
i havent used a text to speech thingy in a good few years.
do they still sound like stephen hawking?
