really slow download speed

So i've tried to download the new patch and i noticed a problem, it was only downloading at around 60/kbs this is stupidly slow but i waited patiently for it to finish. When it was finally done and started to install i got an error that it did not download all patch files.

I came onto the forums too see what they problem was, i found out that i needed to uninstall the client and re-install it. I've come to that now and the downloader that z8 provide gives me that same issue i got before with a slow download speed. I tried one of the other methods and downloaded it from gamershell, this is the interesting part, my download speed was back to normal at around 800/kbs but the version was out of date so i couldn't use it.

has anyone else had this problem or know how i can fix it? it's really starting to annoy me, ever tried downloading 600mb on a 60/kbs? it's not very practical
