Interlakes Wireless Fixed Wireless
July 08, 2024 When we first moved to our home ten years ago, we depended on either satellite or dial-up Internet. Even our cell phone service was unreliable at times as we live in between towns in a dead zone. It was difficult to work from home as I was used to doing before we had moved.
The fiber cable company didn't see the value of installing lines in our area, but the owner of Interlakes Wireless knew our need. He asked if others in our small town might be interested in getting wireless service, so I chatted with our neighbors. We have all had service with IW for years, and it's more reliable than other options for a fraction of the cost.

Bluepeak Cable
May 13, 2024 When we moved into our current house, it had Vast which became BluePeak. Overall, the service we have has been good the past two years with a few minor glitches now and then. My main beef with the service was we were going to switch to Midco as they had a better rate but the new Blue Peak salesman that came around at the time of the crossover said they would match the price here that Midco was offering which was $50 / 1gig / month. It turned out ours was a little over $50 for approximately for may be six months, if even that and then went to $90 / month. I wouldn't say a word but my son, who also switched from Midco to the $50 / 1gig / month at the same time has been at exactly $50 since that time for the past two years. I've called and complained several times but haven't made any headway with even escalating it to a supervisor. We have referred several people to BluePeak but are now considering leaving them no matter what. We'll see what happens in the next couple of weeks.
