How do I change my internet address? Need help updating my IP! or How do I change my internet address

Thx for all the tips, guys! Tried the router reset and it worked—got a new IP after like 15 mins unplugged.

Still kinda confused about VPNs tho. Are they safe? Like, do they slow down your internet? Might try one if this happens again.

Also, anyone know how often ISPs usually change dynamic IPs? Just curious. Cheers!
