Over 100 people attended a drop in event at Brecon Library hosted by Openreach.
The event was held to allow people to raise issues they were facing with their broadband.
Kirsty Williams said:
“Openreach officials were left with little doubt about how strongly people feel about the issue. By contrast, a similar event in Denbighshire had only one person turn up!
“It was so well attended that they have agreed to hold a similar event in Radnorshire in September.
“Many individual cases were raised at the event, including for people who couldn’t make it, and I will continue to pursue these on behalf of constituents.”
