thanks, guys n gals
but it turned out to be a waste of our time n effort, I spent hours researching routers that would work on sky - yet -- he would not test the connection with everything off to ensure its not congestion, only for 30 minutes in the AM and had no problems all afternoon while the house was empty then he went for his tea, I said surely the wife n son can watch TV for 1 hour during peak time ..NO WAY... was his answer... so told him straight "well nothing I can do to help cos you refuse to test properly ...tbh I think its both cos his line quality on TBB (with everything off) wasn't best results and only just made it into the A group and was WORSE than his average for his ISP, quality was 0.51 worse than 0.43 for Sky - mines 0.1 with an average of 0.26 for FTTC (doesn't say ISP)
so when he complains, I'm just gonna say aye tough, isn't it?
