Roamio, FiOS G1100 modem/router, Cable Card and new WiFi router network help

If you are going to maintain the G1100 as the router, then you don't want to install another router as that would segment your network with the typical configuration at least and would certainly cause you problems if you do any kind of show transfers with PC's on your network. It sounds like you just need an updated Access Point connected to one of the network ports of the G1100 (not the WAN port!), disable the G1100 wireless and make sure that the G1100 is still serving as the DHCP server for your network.

If you disable the DHCP Server on the G1100, you'll likely have good result using it as a MoCA Bridge/WiFi Access Point.

You also may need to change it's IP Address.

You do not mention what your internet speed tier is, but if you can get by with 150Mbps or so, you might consider trying one of these, WCB3000N "network extenders". https://www.amazon.com/s/ref=nb_sb_ss_c_1_3?url=search-alias=aps&field-keywords=wcb3000n&sprefix=wcb,aps,255&crid=H56QR020YHH0
They are MoCA based and should be able to take advantage of the G1100's MoCA to easily improve your wireless coverage, and they also have 2 Ethernet ports, you just need a common coax outlet to use them. They can be configured manually or via WPS, but if you use WPS, disable it when you are done as it is insecure.
If these do not provide enough performance for you, there is a newer version, the WCB6200q but these are many times more expensive. https://www.amazon.com/Actiontec-80...1&keywords=wcb6200q+wireless+network+extender
But they will give you 400+Mbps when paired with the G1100.
If you already have that Synology router, you should be able to put it into Access Point mode, which would allow you to take advantage of it's wireless, with or without disabling the wireless on the G1100. Usually, you would just run Ethernet from a LAN port on the G1100 to a LAN port on the Synology unit. Most routers configured as AP's only use their LAN ports, not the WAN port.

Short version, yes, but look for the $14 version and buy a splitter if you need it, once connected, you could possibly just use the coax you have and then connect the mini in that location to one of the WCB3000N's 2 Ethernet port and put a small switch connected to the 2nd Ethernet port to connect other devices or just use a 2 way but get it separately, https://www.amazon.com/Holland-Elec...&qid=1532440600&sr=1-3&keywords=moca+splitter
and you should be good.

 

The newer version is definitely a better device, and if you were on a higher speed tier and willing to spend the difference....you could go for it, but you are only on the 100Mbps tier and the older device, MoCA 1.1, should easily allow you to get those internet speeds and extend your wireless for a very low price. For the investment, the WCB3000N, should do everything you want/need for very few $$.
The newer device (6200) is a bonded unit with the top potential for the current MoCA standards, but to get the max out of it, you would have to pair it with another bonded MoCA 2.0 adapter such as the Motorola MM1000 and stop using the G1100's standard MoCA 2.0 for your MoCA connection but even with those additions, your internet is still going to be capped at the 100Mbps tier, only other local networking transfers would benefit. Either way will get the job done, but if you are planning on boosting to a much higher internet speed, the new one is a good choice.
