Thanks for the advice! I have the latest drivers, it still happens... The only progress I've made is changing the frequency band on the wifi receiver, however it is not a 100% fix as I originally hoped. It would be nice to hear from others having this issue or BT as it's hard to for one person test and figure out what is helping and what is coincidence... There is still the chance it is all down to bandwidth but I my experiences suggest otherwise - it would be nice to know if something has changed on the BT side over the last few months.
