My cable modem required me to call in and answer a few questions.
Your service may differ. Given your prior discussions such as https://www.cnet.com/forums/discussions/security-measures/ I think all this work is not required. I've yet to encounter a compromised router in decades.
However I have worked with folk that are paranoid and all we do is factory reset the device and start over.
Hi. Advice would be really nice.
I bought a new wireless router(Mercusys-only one they had) and I the setup seems real simple, but after doing some googling, I see I might need to enter my ISPs username and PW and address and other stuff.
Is this necessary or will it be automatic?
I need to know cuz I won;t have net access.
What will they ask for apart from ISP username and PW?
I don;t have a modem, just a cable.
I;m changing routers just in case the other one is compromised so I need to disconnect the old one completely.
If the new router doesnt request all the ISP stuff, does that mean I am still somehow using the old router and that compromises security? Should it ask for the ISP stuff?
I also read that if it doesn;t, it means Im just using the router;s wifi and not my cable connection.
Process(cable, no modem)
Turn off old router, take out cables.. should I disconnect the router from PC or ath else?
Insert power line and cable connection into new router, wait and turn on.
Then I get different info on routers web page which i think i can easily access. Dunno about isp stuff.
Thanks!!!!
