Adding Second IP Address

I recently purchased an ARRIS SB8200 modem and ASUS AC3000 WiFi system because our previous gateway was providing poor performance. I connect to my work computer via ethernet cable, but my wife has to use the WiFi to connect to her laptop/remote desktop.  We've been having connection issues and, having talked with ARRIS support, realized the issue is that we need a second IP address / to setup the Link Aggregation. 

 

When I look at the services PDF for my area, I don't see the option to add an additional IP address. Is there a way to get an additional IP address even if it's not listed on there? The issue is making it difficult (nearly impossible) for my wife and I to both work from home.

 

Thank you!

First. Link aggregation won't help a performance / connection / RF signal quality issue. It is for increasing overall bandwidth / throughput.

 

Second. You don't need a second public / WAN IP address assigned from an ISP for link aggregation to be able to function.

@EG  I wanted to see if you could go into a little more detail on not needing a second ip address. If I have a Netgear CM1100 will both ports on the modem be active so you can do link aggregation? Do I have to have xfinity to anything special to get both ports active, if not?

Thanks,

Ed

Only one port is active unless you set up LAG in the user interface settings. It has nothing to do with your ISP. A second IP address is not needed.
