My folks bought a new
Netgear R6250 about a month ago, which apparently worked fine for a couple weeks but now is unusably slow, and I've run out of things I know to try to fix it.
Wireless signal strength is fine. I've farted around with channel settings but we live in a subdivision where we can only really see one other network and it's on a channel that doesn't conflict.
Wired speeds are similarly poor.
Speeds are fine when plugging a pc directly into the modem.
I've used two different ethernet cables, and tried both of them when going from modem to pc, and they work fine for that. So I don't think it's the ethernet cables.
The firmware is already current.
I have of course rebooted everything about 20 times.
Help? I don't want to have my folks buy a new router if it can be helped, especially if if it's the modem (or something else) and not the router. However since speeds are fine when going directly from modem to pc I'm unsure it's that.

The modem is a RCA DCM425. No wireless, just one ethernet port and one that looks likes usb.
If you're getting slow speeds from the direct connection too then the problem seems to be the modem or your computer...
Right now some of our devices work well while others don't at random times. I have a Ubuntu laptop, my Dad a Windows 8.1 laptop and my Mom a Surface. My Mom and I are fine, Dad is connected but can't pull down any data or can do so very slowly.
