“Which Range Extender to Purchase & Cost to Install to Existing Home Network Can GS tell me which Wifi network range extender to purchase that would be compatible with a Time Warner Arris DG860A router connected to OOMA phone system and desk tops? We are having connectivity issues with trying to use laptops and tablets throughout the house. We need connectivity in just about every room of the house. Please advise product make model and cost along with the cost of having the GS setup and install. Thank you.”
