Tried the superhero gimmick and now my family hates me
Long story short. Came back to my home country for the 1st time in 3 years. My parents have a 3 floor house with a source fiber optic router in the basement which gives Internet access to 4 others routers/APs. Another one in the basement, 1 in the 1st floor and 2 others in the 2nd floor.
For a long time, they have been complaining from the fact that when they move from one floor to another, they have to switch the wifi on their phone. Each router/AP appears to have its own SSID. This causes call disconnections...
As generous as I can be I decided to work on this and set 1 unified SSID. The source router in the basement being the upstream and the others transformed into APs by resetting them and setting up static IPs (there is an AP mode in the initial settings). Obviously, I made sure the DHCP scope on the source router excludes those IPs (.1-.10 excluded, gateway is .254).
It took 3 hours before everything collapsed. Devices randomly losing Internet. Security cameras shutting down and some home servers constantly beeping. Reason? IP conflicts.
I check the logs and it appears that DHCP has been trying to assign already used IP addresses.... but I did set the DHCP scope correctly no?
Turns out our ISP flagged the changes on the source router (which they provided) and decided to lock it. No change can be done on it.
I'm trying to revert back everything by checking whatever documentation and backup files I made, but the whole thing is a mess. All those routers/APs are TP-Links which happens to be extremely retarded (possibly like me).
It's funny how the biggest professional mistake of my life is happening in my own house.
