Considering household insects like cockroaches often look for warm, dry locations to lay their oothecas (egg capsules), and have been known to get fried and damage equipment while doing so - I'd say you actually might have a useful symbiotic pal there, protecting your gear (do I see an MT-6000? Great gateway).

You're absolutely right! The spider stays!

The rack goes:
The ISP's ONT (in the hallway, not visible here) ---> a TP-link SG105E swtich:

---> a VPN router (RPi4 + OpenWRT + Mullvad) ---> an Asus RT-AX58U AX3000 router (in access point mode, 2.4GHz turned off) ---> most appliances at home
---> a plain router (RPi4 + OpenWRT) ---> an Asus RT-AX58U AX3000 version 2 router (in access point mode, 2.4GHz turned off) ---> Tor bridge (the white device in the picture, a RPi 5) + occasionally backup for internet access
