Wait. Are you saying your internet (and I'm guessing you're referring to Skype) used to work fine prior to using minecraft?
Yeah, I never used to have issues with skype. Right now I'm trying to skype call with my friends (without doing anything else) and it's still failing.

inaniloquent, there are many possibilities for the change in performance/stability of your network. Have you moved things (furniture, location of PC or router) around...either in the room where your desktop is, or the room where your router is? Also, believe it or not, equipment can degrade in performance over time, ESPECIALLY if it is subpar (cheap) equipment, or if it subjected to suboptimal conditions, such as heat, static electricity, or issues with power (surges, brownouts, etc...).

To start some real troubleshooting, open a command line, and type ping 4.2.2.2 -t
This will start a continuous ping to one of THE DNS servers on the Internet backbone. You are wanting to look at how often packets are dropped (timeouts, TTL expired, etc...) AND latency (ping times).

See how this looks without doing any Skype or Minecraft. Then, leave it going, and see how/if it changes when you Skype and/or Minecraft. Post your results here.......

I haven't moved my room around for a good few months and the living room never changes, so I know that furniture isn't an issue. Furthermore, the dongle I use is relatively expensive (25).. it never gets really hot in my room and we don't have power issues in the area I live in. It's only a year old, too.

This morning the internet was working fine, no problems. When using skype with 1 person it seemed to be okay, too. But as soon as my friend put the server up and I tried to connect, I experienced lag and drop outs. I attached a screenshot.

Wow, notice not only the drops, but look how the ping times spike into the seconds range right before the drops. Looks like Minecraft could either be saturating your Internet connection, or it could be stealing all of your PC's CPU cycles, bogging it down.

A couple more things you can do to narrow it down. Do the same thing with the pings, but this time, ping your router (default gateway). If you don't know the IP address to use, do the command ipconfig. Be sure you are looking at the correct interface. Doing this ping will show if it's the connection to your wireless router that is dropping, or if it is the Internet connection. If the pings look fine, I would suspect your PC is taking a performance hit causing the drops.

Also, you can pull up the Task Manager (CTRL-SHIFT-Escape) to look at what your PC is doing in terms of performance while this is all happening. You can see what process(es) is/are causing the performance (percent CPU and memory usage). You can also see the network performance.

Yeah D: looks like fun. Btw, I just did another ping 4.2.2.2 -t test with just a skype call, and even then it was failing.

When I type ipconfig into cmd, my default gateway doesn't seem to have any values. I've attached a screenshot for that, too. When you talk about the task manager, there are a couple of things I did to try and sort it out. I set the priority of Minecraft & Skype to 'High' to see if that would help but it didn't make a difference.

And whilst I've been typing this out and remaining in a skype call, the internet has stabilised again and there haven't been any drops. The problem is so unreliable in that it happens not at all sometimes and then starts again for ages, it's unbearable.

This is sounding to me like it's an issue with your ISP's connection to you. Do you use cable or dsl? It could just be that you've cable and one of your neighbor's is torrenting or downloading massive files and that's sacking your bandwidth.

Another thing you can try as well.. Have you ever taken your computer to the ROUTER itself and plugged directly in?

This way you can see if its not the wireless adapter.... You have a lot of tunneling.

I am sure that you have a computer next to the DSL/Cable Modem... Can you do a

Speedtest.net

Couple of Tests: (Use your compuer)
1. Directly plugged into the Modem... Copy that
2. Do a speed test, connected by Router... Copy That
3. Ping your router using LAN .. copy results
4. Ping your router using WLAN.. copy results

Then what you need to do is when you have your PC on the LAN
Run your game and skype and perform the previous tests that WEBmattR had you do
to see if there are any changes.

we need to see if its your wireless adapter, the walls, or anything like that.
I know you may have not had this stuff happen in the past but stuff does goes through
deterioration after a while and looses performance.

I seriously doubt this is the cause of the issue since no one else in my household is experiencing problems. This is an issue with my PC.

I can't plug my PC into the router because it's too far away and there is no room to put my PC down there. It's been plugged into it before and it worked fine, but then again, I wasn't having internet issues then.
I might be able to get my PC down there and plug it in if I get permission from my parents... aha.
