In the past I've opened up my provider-supplied cable modem and removed the wifi card which was luckily modular.
This was a really retarded ISP (UPC Ireland) that constantly (like bi-weekly) reset my modem to its factory settings including a way-too-simple wifi password of 8 uppercase characters excluding the I, L and O for number confusion reasons. The entropy was so low that I could crack so my neighbor's passwords in half a day. Basically they were backdooring my entire network.
I emailed them but of course nothing happened. Eventually someone even reversed the algorithm they used (based on the SSID of course....) and published a generator which they reacted to by only sightly tweaking the algorithm which of course got reversed again. They also disabled other features that could alleviate this like bridge mode. It was such a terrible company with extreme contempt for their customers but sadly the only fast one I could get in that backwater town.
But anyway removing the wifi module fixed that huge backdoor at least. I kept all the parts to put it back, but when I quit the service the modem was deprecated and they told me to throw it out.
Later they got taken over by virgin media, not sure if they're still as bad because I left the country.
