Worse than ever!
Can't do those tests on the other network where I'm having most problems as it just crashes when I try and post!

Lots of people were originally having these problems pal, cure for them all, including me was:
1) Delete all internet cache.
2) Close all internet explorers.
3) turn Off PC.
4) Turn off ROUTER/MODEM
5) power it all back up.
Now i dont know why this is, but without step 4, mine was dog slow and kept freezing if i pressed reply etc. Was a real drain.
Point 4 alone fixed mine and a few others. Why? Clueless mate.
