I have a Motorola/ARRIS Surfboard 6141, SonicWall TZ180 and (3) Ubiquiti UniFi AP-LR wireless access points. Two SSIDs configured on the APs -- Home and Guest. Guest resides on the same subnet but is fire-walled off and only allowed to go out to the internet. Cable feed for modem comes into the house in the basement. Cable modem, SonicWall and 16-port smart switch are in the basement. 5-port smart switch is in the shop. All of the APs use proprietary POE injectors that sit right before the device.
Maybe someday if I get a newer SonicWall I'll setup some VLANs, but I see no need for that now.
I have TWC 15x1mb and am very happy. Internet is peppy and performs well. Not a hiccup from the modem or SonicWall in the past year or so. They both sit on a UPS. The access points are excellent. One in the middle of the house downstairs, one in the middle of the house upstairs and one in the shop via a couple hundred foot run of direct burial CAT6 in conduit.
The long range UniFi AP-LRs have a range of 600 feet! I am somewhat brainwashed into not liking any consumer grade equipment. Probably the stuff I'd like already closes in on business grade equipment but with less features.
Everything works very well, a lot of the time its not the bandwidth package you have, but crummy equipment.
