Your Eero base station and TP-Link router are probably falling repeatedly because of the weight of the cables hanging from them. It's tempting to put them at the edge of the desk so you don't see their cables and because you don't really need them any closer to you than that, but you have to support the cable weight through other means or they'll slide into the abyss.

I dislike cable untidiness, and I especially dislike having cables at my feet or tangling with my legs as they move around under the desk. Here's my process whenever I move offices, move home, or make major changes to my setup; you might find some part of this that you like. The instructions are written for a single desk, but adaptable to any number, and they are biased toward your setup where your Wi-Fi AP and your router are not the same box.

0) Unplug everything and set aside all of the cables. You're going to start with just the equipment, get it in place, and figure out the cabling middle-out. This is a good time to examine all of the now-unplugged equipment to see if some can be set aside.

1) Wi-Fi access points work best when up off the floor and not behind things. Figure out where your source of Wi-Fi should go, and put it there. This might be on top of furniture someplace, but you might find wall-mounting to be your best option. Make sure you can get power and a long-enough Ethernet cable to this place. If your router is just routing wired signals and NOT providing Wi-Fi you can safely hide that someplace, so you don't need to wall-mount it or otherwise make it visible.

2) Put the equipment you will interact with most on the desktop where you will use it, and arrange it as you like. If you have a separate CPU, put that where you would like it to go.

3) Wire these things together, using existing cable management features (such as the typical hole in an iMac stand) to bring necessary cables to the back of the desk. At this point you'll have ignored power and Ethernet but taken care of other interconnects.

4) Neaten the top of the desk as much as you can without bundling before proceeding.

5) Decide wether you want to bundle the loops of cable hanging from the back of the desk individually or in a single bundle. If you are fine fishing through a single bundle later, great. If not, let your retentiveness flag fly. I like to use velcro for this purpose, but there are so many options you can do what you like. Tie up enough cable to form a bundle, close to the bottom surface of the desk, with a little slack so you can suspend the bundle from the underside of the desk while leaving a bit of ease so the cable isn't taut.

6) Hang your bundle(s) from the underside of the desk. Again, there are so many ways to accomplish this, but you might like Command cable clips, or Belkin cable domes, or BlueLounge cable drops, or what have you.

7) At the desk you are left with power and Ethernet to take care of. Plug these cables into the equipment and let them pay out the back. Now you are ready to figure out where your router and power strip needs to go to get to everything.

8) I like to mount my power strip to the bottom of the desk so that only one power cable leads from the desk to a wall socket. I typically use the star- or pear-shaped holes in the bottom of the power strip to screw it to the understood of the desk. You'll want to sink a couple of pan-head wood screws, short enough not to reach the top surface of the desk, and slide the power strip onto them. Then you can connect and bundle power cables as you did before, and route the single power cable to the side or down a leg.

9) A router, if it is not providing Wi-Fi, is essentially just a power strip for the internet. You can do the same mounting trick for your wired router if you like (and if you can reach the AP from there) – most have star or pear-shaped holes for mounting, and in a lot of cases Command strips will also do the job as small ones are less heavy than power strips. You'l want to make sure the weight of any cables is taken up elsewhere, though.

10) You have three jobs left to do. The first is to get your router wired to the AP and the machines it will serve. The same cable tidying rules apply. Try to bundle your ethernet cables in loose loops; it's kinder to the cable. Since you have all the ethernet cables from machines leading out the back of the desk, they should be easy to find and bundle.

11) The second is to get power anything that doesn't have it (as in step 8) and get the power strip plugged into the wall. Everything should come on at this point; if it doesn't it's a sign you forgot something. When I have to snake a power cable across foot traffic I like to use a PVC cord cover. You can usually get a few cables in the smallish ones, but they come in every size.

12) At this point all of your equipment should have power and network, be interconnected, and all the cables are bundled and suspended under the desk except the few that need to lead somewhere else. If you care to neaten these by strapping them to a leg or something, now is the time. Admire your handiwork! Everything is plugged in, accessible, going nowhere, and it's pretty easy to follow a cable of interest in either direction.

You might have some cables left over at this point. If everything works, you didn't need these.
