Friend uses a "well known
) ISP, lives, say, 320m as crow flies from exchange, and uses a HP CompaqCQ70 Notebook. Router is ISP supplied D-Link DSL2680. He uses his computer less than 6ft from the router; more like 4ft and there are no impediments.
From what he told me, recently he has been unable to connect wirelessly. He has checked his configurations log ons etc. are correct. ISP changed channel from 8 to 9 with doubtful benefit. From no wireless it's now 60+% no connection, so he's still unhappy.
Can the many brains on here come up with some suggestions I can put to him or at least reasons for his troubles?
