DD-WRT does a good job if you use high-security passwords.
I use KeePass and generate a 256-bit password with letters, numbers, spaces, symbols, and ASCII characters. I can only access my router from home by copying the password from the KeePass database on my encrypted thumb drive which is paired to the TPM chip in my desktop which is powered off when it’s not in use.
It’s not fool proof by any means, but if someone really wanted my shit, they’d have to work for it.
It’s vacuumed today and analyzed whenever they need it.
In 10 years they may very well have the ability to read it in real time. They, after all, have all our tax dollars to spend on that.
I also have a DD-WRT router but think he was referring to routers at the ISP level.
Is there any programs similar to MRU Blaster?
