This was my speedtest done last year 19th Feb 2014

and my speedtest today

That's shocking and even though I live rurally and our exchange is probably old, I was at the same address on both occasions.
I have had problems with broadband dropping out the past two days and the phone line has been terrible (crackling) and went dead on two occasions. I spoke to Vodafone CS person about this and she tested my phone line. She said it was good, blamed my filters for the problem and told me to replace them. Although I cant see how dodgy filters would cause the issues with my phone line, I unplugged everything last night and only plugged in my router (Belkin F7D3402 Share Wireless Modem Router) and while the connection hasnt dropped today (yet) it is so slow I might as well be on dialup (I havent even used 10% of my monthly data allocation). The phones are still unplugged but I just plugged them in to see if they work. The older phone (Uniden dect 6) doesnt get a dialtone (and I told her this) and the new one (Uniden Xdect 6135BTU) does but will only connect intermittently.
Thanks for any help and let me know if you need more information (OS is Win7 in case it's relevant).
