Oh, we're definitely getting the new modem. And new NICs for 2 of the roommates, and new ethernet cables (apparently we have mice now, 2 cables are chewed up). This is quickly becoming an even bigger issue than I'd thought.

Fixed! Well, partly, anyway... The router is now going at nearly full speed. 419.58 down, 23.24 up. Downgraded the router's firmware to the last version. Still seriously considering replacing that modem though...

We're paying $10/month for the "rental," which wasn't by choice. Our old modem got toasted back in June, and we needed a replacement right then (2 people here working from home). So we started renting from Spectrum, and have had nothing but trouble since. I think we'd break even faster since we...

Close enough to be twins! Just the two lights on our's though, power and "Online." Roomies and I have been discussing buying a modem outright, but the best we can find in our price range is the Netgear CM1000. Would it be worth it? My thought is order it, try it, and if it works, boot the...

That rogue IP only showed up on the Netgear router. That aside, I finding astronomically unlikely that 3 routers, by 3 different companies, would have the exact same download speed issue.

Let's try that... 1472 gives us no fragmentation. Trying 1473 gives fragmentation, so 1472 it is. Adding 28 to that to get the "optimal MTU setting" gives us 1500. Which is what the router is set at already.

Tried that with a Pi I have laying around. No ping. It's not part of our LAN at all. I think that's just a bug in the router.

Highly unlikely. 3 routers all infected straight out of the box? Plus I'd notice the increase in traffic.

I'll try that this evening when I start testing again. Seriously, at this point I'm almost ready to tear it all down and start at square one.

Running it now, and not finding anything out of the ordinary. Whatever is causing this speed issue is between the modem and the router.

That's standard. I do a full disconnect/wait/connect every time. Even doing that, when going through the router, we don't get the "initial burst" of speed one would normally get.

Nope. The modem is hobbled (badly) by Spectrum. 1 ethernet port, no user accessible functions. Any changes to it have to be made by Spectrum. As for that rogue address, I can't find a mention of it anywhere in the router, except in the logs. The WAN IP (assigned via DHCP from Spectrum) is in...

Highly unlikely, as they struggle with using Alexa. When I've been testing this it's been with ONE PC at a time, Wifi, QOS, VPN, etc disabled. I've tried pinging that rogue IP (yes, the router is still trying to offer it), with the usual result: PING 192.168.10.163 (192.168.10.163) 56(84)...

That is a rock solid consistent pattern. And it happens no matter which desktop system the router is cloning a MAC from. Last night I even cloned the MAC from the desktop running a clean install of linux via liveboot USB. Nothing running, no apache/mysql/other servers, just sitting there running...

3 of the desktops are Windows 10. the 4th desktop is Ubuntu linux. 1 of the laptops is Windows 7, and the other is Ubuntu linux. So I'm fairly certain we can rule out it being a Windows problem. The Netgear support rep I've talked with got me to adjust the MTU, twice. No joy there, either. I...
