We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.

CenturyLink

I have unlimited internet (no overage bills). My internet is now 2 1/2 times faster on download and 9 times faster on upload than others with a boost. I have one bill that is guaranteed to be the same price for life with my phone and internet bundle. The phone we have in the bundle from CenturyLink will still work in a power outage and is 40% cheaper than others and 911 knows immediately where I am calling from. If the power goes out with VOIP, you are done. 911 may also not be as effective on VOIP. But on fiber from Centurylink, it is a hard line. Also, with this bundle, I got a free modem/router. No rental, just outright free. It's mine! And the installation was free! All that money we saved and all that extra speed on the internet is wonderful! I am winning in multiplayer games. My pings are insane! Downloads go too fast compared to others. No throttling, I don't "compete for bandwidth from neighbors". I don't "share my bandwidth with people passing by our house". The speeds are always the same, super fast. Support responds fast. I get to speak to a rep in less than 5 minutes with CenturyLink on the phone. Or I can tweet or email or chat. Anyway, I've gone for the support and it's been great. Install was 30 minutes. The rep was awesome. Also should mention that I put a poll, 84% voted CenturyLink as good. Many people posting the same pain I had with our previous ISP and how much they love CenturyLink. That said, I can't believe all these negative reviews.

XFINITY from Comcast

First time Xfinity subscriber. Exceeded my expectations. I can honestly say I was very impressed with all aspects of Xfinity. I just purchased a home in Delray Beach FL. From the initial appointment call to complete installation, Xfinity exceeded my expectations. Very impressed with the Tech. The tech arrived early. He introduced himself and ask me about my expectations. He explained what he was going to do and would have me watching NFL football today. Walked me through the setup and all options of the remote. I ordered cable and internet. I will say the internet service is faster than others. Very impressed with Xfinity.

Worth it

I just did a transfer of service, in the beginning, I did have trouble and I was already in the mindset of it taking days or even weeks to be resolved. Fortunately, I was helped by Chat support service, it was a one on one service that helped me resolve my troubleshooting when I couldn't be on the phone, he spoke very professional, and was quick! I definitely recommend it.
