That's just a symptom. Something else is the bottleneck on speed. Could be the OS and drivers used for computer. Reload the driver files for your computer model or motherboard. Is your connection by wifi, or cable to modem? Who is your provider? I had a problem and my verizon ONT needed upgrading. Is it cable all way to home, or FIOS which then goes to ONT and MOCA conversion to cable?
Hello All,
I have this problem with my internet speeds; when I run Speedtest it quickly shoots up to about 110 Mbps down, and quickly begins to gradually fall, usually ending in the 20's Mbps down.
I started with their modem, switched to a Netgear, then to an Arris. I also started with their Sagecom router, then swapped it for another of their Sagecoms, then bought my own TP-Link. So I've had 3 modems and 3 routers, but this problem is consistent through all.
I've had 3 technicians here; first swapped the router and put new connections on the coax, second replaced something outside the house and ran a bunch of tests, third ran a new cable from the pole to my house, and also scheduled for them to check the "tap" on the pole at the street.
I'm at a total loss, so figured I'd see if anyone has maybe experienced this and has a suggestion. Oh, and my internet plan is for 100Mbps down.
Any insight is greatly appreciated!
Thank you in advance ![]()
