EE added another 18,000 home broadband subscribers during the third quarter of 2014.
The broadband provider had a total of 793,000 fixed-line customers at the end of September, up from 775,000 at the end of June.
The rate of subscriber growth was down slightly, after EE added 30,000 new customers during the second quarter of the year.
However, EE continues to attract new customers to its fixed-line business - which offers both copper and fibre-based broadband deals.
Further growth was seen by EE's mobile business, with another 1.4 million people signing up with the firm during Q3 2014.
This means EE now has 5.6 million mobile customers using its 3G and 4G services.
In a network and company update, EE said its £1.5 billion investment programme "is delivering results".
The company noted that it is making improvements in terms of coverage - particularly in rural areas - and also speed, courtesy of additional 4G equipment.
"We are this year extending our unique double-speed 4G service to 40 of the UK’s busiest cities," EE noted.
"We were the first UK operator to roll out LTE-Advanced, demonstrating speeds up to 300Mb in Tech City, London - ahead of a city-wide launch."
