Windows has an I/O monitor in the Task Manager - that will help give you an idea of what your read speed is. If your laptop HD is mechanical (disk plate with arm) then that may be the reason why your read is low. Your Red Drives should be able to handle high write speeds though based on the specs.

3.77 Megabytes per second is about 31.6 Megabits per second. The slowness may not be your network, but it may be the read from your HD and the write to your NAS (I/O).

The only risky stuff I do is download pirated games on my desktop and very, very rarely watch corn on the laptop.

Downloading illegitimate software and installing them onto your PC will bypass all the security set by your network devices, as the networking devices doesn’t have the capability to scan/check if a downloaded file contains malware or not. A good anti-virus software may be able to sniff-out a malware from your downloaded file; therefore, building your own router doesn’t really help you in any way.

Might be good to cross post this on r/eero

Here’s an interesting experience - I bought a 10-year-old ISP-provided router 2.5 years ago from a friend, disabled it’s wireless signals, plugged it into my ONT and plugged everything else on it (including my access points) and it has never failed me. The only times it restarted was when I lost power; other than that, it’s running without any problems. I don’t know for how long though cause it’s old LOL! What’s good though is if my router does fail, all I have to do is replace it with a new one, and keep everything else intact (i.e., switches and access points) because it is decoupled.

Is it possible that your house’s electrical system is not stable, causing surges that impacts your router’s performance? Maybe try plugging your router to a UPS or a surge protector?

I have a 300 mbps symmetric fiber and my ethernet-connected devices (TVs, PCs, Laptops, PS5, etc.) are working perfectly; I’m not experiencing buffering at all.

There are a lot of factors that may be causing your problems, such as bad cables, bad ethernet/NIC of your PC/Device, ISP issues (such as Verizon FiOS wherein the Nokia ONT cannot handle malformed IPv6 packets causing issues), etc. If you can give more information about your network topology, we **may** be able to pinpoint what the problem is.

Did you contact Telus? They set it up so they should be responsible in ensuring all your ethernet ports are working. Was your internet service activated?

I have a Deco M9 Plus (3 nodes), 1 node per floor on a 3-floor townhome. Initially, only 1 out of the 2 satellite nodes were connected via ethernet, but I noticed network performance issues on the 3rd node that’s using wifi backhaul, primarily because the distance from the main node to the 3rd node is far, as well as the floors, ceilings, walls and other furniture/interference that’s causing the issues. I don’t know if it may be a problem for you depending on your home’s layout (including the materials used to build your home, i.e., concrete/brick dampens signals way more than dry wall, etc.).

Another thing to consider - M9 Plus is an old model (at least 4+ years old). If you are good with that, then go forth and acquire; otherwise, you may want to take a look at other products.
