Will There Be A Problem If I Connect The Voip Adapter To My Cable Modem Instead Of My Wireless Router?
I have a wireless router, and also a cable modem. Is it okay to connect the VOIP adapter to the cable modem and have an Ethernet cable go to the wireless router (which is connected to the computer)? I really don’t want to connect the VOIP adapter to my wireless router…will that create any problems or decrease service quality? Please briefly explain why. Thank you!

My experience with the VOIP adapter is that it NEEDS to go between the cable modem and router. It wouldn’t work if it was attached to the wireless router. It needed this ordering because the Cable modem gives it a distinct IP address, which the VOIP needs to connect properly to the outside world, but when connected after the router, it will have a local address (probably on the order of 192.168.1.XXX), which will screw with the VOIP packets coming from the internet.
With the VOIP adapter between the modem and router, it will better manage the packets to allow the VOIP packets through with priority over the router computer packets, giving the VOIP better quality when it needs it.
Of course, the last time I used VOIP was from AT&T from more than a year ago, but I believe it is an across the board setting. Someone correct me if I am wrong.

I have a Linksys VOIP adaptor connected to a Linksys wireless router and had no service disruption using both VOIP and internet….But I did have problem when I had phone line from VOIP adaptor connected to a wall jack….too much noise… I had phone line from VOIP adaptor connected directly to phone’s base station and it eliminated a lot of the noise…

Connecting your VoIP device directly to the Cable, DSL, or Satellite “modem” is actually the best choice. This will allow the VoIP device the priority on your network.
