New custom for UK broadband connections fell in the third quarter, according to estimates from a market research firm.
Point Topic predicts that UK broadband providers garnered 470,000 new subscribers during July and September.
During the previous period, an extra 510,000 new subscribers had been signed up.
The addition brings the number of broadband connections in the UK to 14.98 million in total.
Commenting on the prognosis, Tim Johnson, chief analyst at Point Topic, said: "The reason for the sudden drop is largely the shrinking size of the remaining pool of dial-up users.
"There fewer [dial-up users] and the ones that are left are more resistant to change. On top of that, the industry has been failing to bring enough new homes on line."
Nonetheless, Point Topic expects that the number of broadband lines in the UK will grow to 15.5 million by the end of 2007.
