Slow internet after a long power outage

AilingCRANE_ · June 22

Just went through a 4 day long power outage. Power came back on the 20th and my wifi is super slow. I ran my wifi routers built in speed test and I'm getting 413 mbps which is on part with the speeds i was getting before the outage( in some cases higher). I did a speed test on my phone today and noticed I was only 33mbps download speeds (same story on my pc and other devices)

does anyone have any solutions? Ive tried power off/power on, disabling ipv6, changing DNS, and i updated my wifi card drivers but nothings worked thus far

have you considered this might be an ISP issue? i mean.. if power was out for 4 days, there might be a lot of people catching up on online tasks and/or some parts of ISP infrastructure may still be running on minimal power limits.

You mention wifi, but not wired.

Is the cyberpunk steam download on a wired PC ? Or is that an older picture you took before the outage to show the download speed ?
Because that looks like the correct speed to me. At 431 Mbps network speed.

If the issue is primarily wifi related and it works fine over ethernet, it could be that you're on 2.4Ghz instead of 5Ghz for some reason. Decoupling the two in your carrier provided modem/router would help diagnose this. I know many of them like to merge both together into a single ssid, with the router deciding by itself if you deserve faster speed today or not. It's one of the first thing I disable. When at home, unless you live in a huge house, there's little to no reason for your phone to be connected to 2.4Ghz if the router is located in the middle of the house. Keep 2.4Ghz for IoT devices and decouple the 5Ghz with its own SSID for your devices.

Hi. Yes, it's a picture taken before the outage to show the difference in speed. Secondly I'm 100% I'm only on 5ghz because it's only network my pc is connected to, but I will try your solution to see if it works.
