Maybe get a cat thermal pad. They are always cold. I had issues with mine cuddling up to my warm thighs after a physical therapy cycling routine. She was causing issues so I got a pad on a hunch and a whim about her thermal motivation. She is on this thing ~23/7 since 2020.
I actually have one, as well as a 3d printer, I was sort of toying with the idea of taking the thermal pad, printing a base that looks like my router, and installing some tiny fans to blow the slightly warm air upwards, it would be a biggish product but I'd be down for her to keep the spot while I keep my router free of heat damage
I actually did a similar project for her which you can see in the Bottom left, it's a little monitor that actually works and used to play bird videos so she could sit next to my desk and feel like she had her own monitor. Since then I've repurposed it to run a media server but she still gets to look at it i suppose . The back says peppersoft
I hung my router on the wall and replaced it with a warming pad. It’s all adorable fun and games until your router’s cooling vents get clogged with floof.
I have that router. It's a great router. Never drops out, never needs to be reset. It just works, and works well.
My only complaint is that it has a tendency to refuse to switch back to a DFS channel once the airwaves are clear, but I mostly use ethernet anyway so it's not the end of the world. I'm just happy to finally own a router that does what it's supposed to without needing a power cycle every few weeks.
Better range, better speeds, better control panel, and some extra features that can be great for gaming or self-hosting servers (eg: network-wide adblocker, nat loopback)
An ISP provided router is generally going to be the cheapest device they can buy that will be functional on their service.
This means that if you are using more than a handful of devices it can overwhelm the processing power of the router leading to lag, drop outs, loss of connection, sites taking ages to load, etc.
When you buy your own router you get to choose a device that fits your (and your families) needs.
If you shop at an actual tech shop instead of your local big box store, you will find a huge number of different devices available that are far more capable than either the ISP's or big boxes stores offerings.
There are even entry level professional units that can support about a hundred devices connected to it without breaking a sweat.
When I switched from ADSL to fiber years ago I purchased a D-Link DIR-879 router which at the time was good enough for my needs but had some drop out issues so I have recently upgraded to a MikroTik RB960PGS Router which is both a wired only router (no inbuilt WiFi) and much more powerful both in performance and features.
I can use a Wifi access point or two to get WiFi where I need it and it can be upgraded as new WiFi standards come out without replacing the router.
Mostly directional range, but mine also offers a huge suite of features so I can have total control over my network, as well as wifi 6 which is nice and a bunch of high speed ports
