Broadband has become an essential utility, yet our broadband satisfaction survey has shown that many customers simply aren't happy with the service they receive.
But many people who expressed dissatisfaction and gave their provider low ratings had been with the same company for three years or more. Less than half of those we surveyed said they were likely to switch providers in future, while some 47% said they'd never switched at all.
If you're one of the people struggling with a poor connection, you may be also be wondering whether a change is worth it.
To help you weigh it up, we asked those who had switched what made them take the plunge - if any of their reasons speak to you, you may find that it's time for you to switch broadband provider, too.

Price rises were the top reason customers decided to ditch their provider for a new one - 27% of customers told us they'd switched after being hit with a price hike.
Customers that had left three of the biggest providers were the most likely to say a price hike had driven them away - around a third of those departing BT, Sky and Virgin Media said this came down to a price rise.
A couple of the major providers (including Sky and Virgin Media) announced price rises this year. If an unexpected price rise is greater than inflation, you should be given the right to switch away, even if you're still within the fixed term specified in your contract.
Another 5% of respondents told us they'd changed providers because their introductory offer they'd been on had ended - which also often means a jump in price. Many of the big providers offer affordable introductory deals, with the tariff rising at the end of a 12, 18 or 24-month fixed term. Our analysis of deals has found that jump can be quite large - as great as 90%.

Some 18% of broadband customers told us they'd experienced frequent connection drop outs in the past year, but for 13% of those who had switched, this was what drove them away from their old provider. Customers who left TalkTalk, Vodafone and EE Broadband were the most likely to say that connection problems had prompted them to switch.
But if those issues become a regular occurrence and you've had enough - it's time to switch provider.
One in thirteen of those who had switched told us they'd done so simply because they'd found a better deal with a new provider. No single provider was more likely to have customers depart for this reason than any other provider included in our customer satisfaction survey.
