Latency and Packet Loss Issues

Question

About a week ago, my internet began to have high latency (stable at around 250), and a small amount of packet loss. Since then, the latency has died down, going back to normal but every minute or so jumping back up to about 250 +/- 250 for about 30 seconds before going back down. The packet loss came about occasionally, and only around 1-2%, but earlier today was at about 10% and wouldn't drop.
From what I can tell, all of the issues appear randomly with nothing making them appear. Nothing has changed since before this started, it just came out of the blue.
I use a wireless connection as an ethernet cable won't reach to my PC.
Here are some ADSL stats:

All help would be appreciated and any information needed, i can supply. 
Thanks.
Edit: Also, here is a Netalzyr test if that shows anything!

Answer 1

I did a quiet line test earlier, with a cordless phone. There was a humming which i think was just normal, but about 30 seconds in there was a crackle which lasted about half a second. I kept it on for about 2 minutes before turning it off.
