Don't know why the wifi performs so bad, PC in the same room as the Router only a few feet away and a 5 bar connection. Just thought I would try with an Ethernet cable and now I won't go back to wifi. In fact just ordered a 5M Cat 5 cable from eBay as the current one is only 2M and its ok temporarily.
Just done some testing and I think it may be down to my USB wifi adaptors as my machines with built in wifi seem to be OK speedwise.
