Is this a form of (self-inflicted) ARP-poisoning? [closed]
TL;DR
Are two different local, home networks (different routers, different IP ranges, different ISP connections) operating in very close proximity, but using the same WiFi SSID name and same WiFi encryption + password, effectively performing a sort of ARP-poisoning attack against each other? Or would this sort of setup be classified as something else?
Long story for those interested:
A non-technical friend of mine has asked me for help with his home network, complaining about internet speeds and connection quality. What I saw at his house was a bit shocking. He has two ISPs (sic!), and three routers (all working as WiFi routers, not pure APs), each of which creates its own internal NAT network, each with a different IP subnet. At least two of these routers are using the same SSID and WiFi security settings.
It's quite a mess. And none of the routers even support a pure AP mode OOB (custom FW is possible, but not a solution I'd like to implement for someone without technical know-how).
In any case, I think the reason internet quality over WiFi is so spotty (despite the otherwise strong signal strength) is because the different routers, operating with the same WiFi parameters, effectively get in each-others way. Which, I think, is a classical example of ARP poisoning, except in this case "accidental" and "self-inflicted". Would this be a correct classification or could this be compared to some other sort of attack?
I know that WiFi networks aren't exclusively identified by SSIDs but also BSIDs but most laptops / phones will seek to bind to a network by the former...
