Fybercom Fixed Wireless
July 11, 2026 This used to be a good company. Started to have buffering issues on all devices. Took 10 days to get a tech out. Installed new modems. Problem still there. Call tech support who indicated it is a problem with one of their towers and that it affects numerous customers. Asked if the Engineers communicate with tech support and apparently they do not. They want me to change to fyber and asked why they don't communicate with the affected customers who are waiting for issue in the tower to be corrected, especially if they can identify each customer that it is affecting. The time it takes to get a service tech in to change the modem, rather than being honest that something else exists is not a good model plan to show support for the customers. Being down without your internet which supplies TVS, Security Systems and other devices while still paying the bill is highway robbery especially at the prices we are being charged.

January 30, 2026 The survive overall is consistent but the speed is only fair at 100mbs. The service in prime hours 8:00PM to 11:00PM seems throttle backed from Tuesday to Saturday. Lastly, we have been in auto pay with them for 12 years and we never hear from them at all.

Fybercom Fixed Wireless
January 18, 2026 Have had their internet service since March 2025. The first 7 months it was excellent, but the last few months it has been awful. My wife works from home and it is a necessity to have reliable internet access. There is no customer support on weekends or until 8am weekdays. 3 times it has been off all day. 3 times it went out in the in middle of my wife working. Very rarely do they answer the phone. You leave a message and it takes them 3 or 4 hours to respond and sometimes it isn’t until the next day. Now for the reason of this review. Internet went out 1/16/2026. Called and left a message. Received a call back 5 hours after the internet had already came back on. They wanted to do troubleshooting, but I explained that my wife was working. Made an appointment for 3PM 1/17/2026. Wife quit work early so I could take their call so they could do troubleshooting. NO CALL! I can put up with a lot of things, but this is unacceptable!!!
