I'd like to find another ISP, but people tell me that their ISPs have problems too. But some attributed poor performance to congestion on the Internet, so they saw their ISPs as blameless. Nationwide access numbers are important. Some respondents have local ISP service but also an account with a national provider for access on the road. Technical support matters.
People remember and resent bad tech-support experiences.
MindSpring, which had the highest overall satisfaction rating, had high satisfaction ratings for technical support. Support for 56 Kbps is important. E-mail is your identity. A few people said they were considering an alternate account with a different ISP, because they were having so much difficulty accessing e-mail.
