We recently completed the construction of our house which has an accessory unit that we plan on renting out as a VRBO. I'd like to use our house wifi to give guests internet access but I'd like to have a separate wifi name / password for them. I'd also like to restrict the bandwidth they can take and have some sort of protection from visiting malicious sites while on my wifi. I'm sure this is pretty straightforward but computer networking is not my strong suit.
I have DSL service through Alaska Communications (ACS). The modem they provided does not offer a guest mode. I assume I'd have to purchase another modem to serve as an access point or bridge? Am I correct? I appreciate the help.
