Internet very Unstable after power surge

[DJxTimeKiller]

This problem started over a month ago when the power surged on a windy day. I have uesd different speed test I get drastically different results. I'm paying for 100 down and 10 up. Some timages speed test sites show 3 times that amount and other time 1%. This seams to fluctuat buy the second. When looking at task manager ethernet performance the graph shows it going from 0 to 100 when playing on line games (it looks like an ekg when someone is having a Hart attack). In the last month I have gotten a new computer and replaced my cable modem. The ISP people have come out twice and I have scheduled a 3rd appointment. I have tried lots of things like Turing off programs that I don't use and disconnecting device not in use. I can't think of anything else to do and can I find a new new info on the Web. Any help or advice would me much appreciated.

The new computer was planed before the Internet problems. The old modem was a 2 in one with wifi. The new one is just a Cable modem. Not sure if one is better than the other.

I you didn't already replace the data cable from your modem/router to your computer. Replace them as needed. I had a power problem that even shorted out the cables. You didn't say if you have a router in the mix? Or if you do have one if it was connected at the time of the surge.

Sorry for the down vote i did not mean to do that and i'm new to wright in forums. I started with a modem router combo. i replaced it with a new modem and router that isn't one unit. Cables to. The guy from my isp came yesterday and told me that the signal to my place was getting interference somehow. Not sure how you get interference on a cable internet. O well they going to try to fix it to day.

Okay, it is good that you replaced everything. Power Surges can be tricky. The Cable internet has several points that are powered to amplify the signal. In addition to spliters and filters some of which are powered. Any one of those could have been damaged by the power surge.
