I have several questions regarding my home network, and I have virtually no experience servicing networks, so please forgive my ignorance asking these questions.
I currently have a Motorola SB5101 modem attached to a D-Link DIR-655 router. My Internet provider is Comcast. Recently I have been experiencing numerous disconnects and modem reboots, thus, I am considering purchasing a new modem. Specifically, I am considering an ARRIS / Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem. My questions are as follows:
My network consists of three laptops, one wireless desktop, three cell phones, and a wireless printer. When I replace the modem, will I have to manually add all these devices to the network again, or is there a way to save the settings?
As long as I am replacing the modem with a new one, would it be advisable to upgrade the router as well?
Thanks in advance,
If you are only replacing the modem, but keeping the router, then you should not need to add all your devices again since they are connected to the router, not the modem (so to speak).
If you decide to get a new router as well, then you might need to add them all again depending on how you set the new router up. If you set the new router up to use the same subnet settings and use the same WiFi SSID, password, and encryption method, then in theory, all your new device should automatically connect since they are likely set to remember the SSID and password for the existing WiFi network. The only possible wrinkle would be if you are using MAC filtering and want to continue using MAC filtering.
Just out of curiosity, what have you done to try to diagnose your current setup? Have you talked to Comcast to see if it might be something on their end? The point is to make sure that you have basically exhausted your other possible issues otherwise you might buy a new modem and still have the same problems if it was something OTHER than the modem.
