So I see my options as:
1. Do nothing. Not a good option as my current modem/router plus one range extender is quite old and not capable of handling the speed I have from Comcast.
2. Replace my current setup with a Comcast compatible modem/router and a new range extender. This should probably work however I really could use an additional range extender but reading using more than one can be very tricky.
3. Comcast compatible modem only with a mesh system. I would need at least 3 mesh units and this can be costly.
4. Last but not least. A separate modem and gaming router which would have the largest coverage range. Another costly option but one worth exploring?
The big thing is the cost and how long until the new equipment becomes to old. Entering 10 years on my current setup.
