I have comcast modem which has only one RJ45 Port. I need atleast 2 ports - one for the wireless router for my laptop and other port for VOIP Adapter. How do i solve this issue? Should I use the Ehternet Hub or splitter? Please suggest.

Hi, Does you wireless router have some Ethernet RJ45 connections. If so use one of them. The next option is a small hub connected to the modem, and the wireless router and VOIP connected to the hub. The smallest hubs these days have four of five ports. For your use a standard 10/100 hub will do the job. You will also see small 10/100 switches. These are usually more expensive, but they have more logic built in to them to direct network traffic. Regards

Thanks for your reply. Yes. The modem has one RJ45 connection. I need atleast 2 RJ45 one for wireless router and other for VOIP Adapter. I tried Modem -> Wireless Router -> VOIP Adapter. This is not working. I am getting dial tone on the VOIP but not able to make outgoing or incoming calls. Something is blocking my VOIP. I think i will go ahead and get an RJ45 Hub. Thanks so much.

Hi, If VOIP was not working when connected through the wireless router, it was likely due to the settings in the wireless router. I am not familiar with the ports used by VOIP, but somewhere in the documentation it will tell you which ports need to be open, (and for which protocol TCP /UDP). Many routers can be accessed from a web browser, and ports can be opened for specific types of traffic. Remember that your router acts as a firewall, so don't connect any PC's between your DSL modem and your router. Regards

Great. Thank you.
