Wireless sometimes drops down to kb/s speeds

[goodbyebluemonday89]

So, I've been experiencing an issue for the past couple months with my wireless internet. I've contacted my isp several times about it, and they assure me it's not something on their end. During online gameplay, I experience constant hickups, and sometimes the connection drops down to kb/s download speed during the day. It's been something that I've put up with for a while, but is starting to interfere with my online work.

I typically use a wireless device, so it's hard to say for sure if a wired connection experiences the same issues or not, but I've checked the wired connection a few times when the wireless dropped, and it didn't seem to be affected at all.

I recently replaced my router with a https://www.amazon.com/gp/product/B00BUSDVBQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

and my usb wifi card with

Neither of which solved the issue, so it has to be bandwidth/modem related, right? Any troubleshooting advice is greatly appreciated.

interference from something(like a microwave)?

My desk is about 15 feet from the router, with nothing between us but a tv and a couch. Not sure what would be causing the interference.

Have you added any new devices to your network?

We got a Nintendo Switch, but it's usually off, and the downtimes have been happening since prior to getting it.

Do these problems occur for that specific PC and all other devices are fine? Based on what you have said and what you mentioned in your first post, it seems like the modem could be faulty. If the PC you are using is the only one experiencing these problems, perhaps a recent Windows update isn't getting along with something. Maybe try disabling Windows scaling heuristics. https://blogs.technet.microsoft.com/networking/2016/08/11/an-update-on-windows-tcp-autotuninglevel/ (use the last command)

It could be background processes downloading or uploading at inconvenient times so try disabling some startup programs. Maybe run a Malwarebytes scan. Your anti-virus could be interfering with the firewall if you have a third party one. Maybe try changing your DNS to Google or OpenDNS. https://developers.google.com/speed/public-dns/docs/using
