You probably can find an ethernet over coax adapter.

I have ordered just such an adapter, and so I am waiting to see if it works!

Ralph Grabowski

Good luck!

Thanks for documenting your Ubiquiti installation. Am adding a link to your writeup for my CompTIA A+ students.

I have one of these as well to replace crap wifi in the Icotera router I got from my ISP. Good news - very stable wifi. Bad news - JAVA based config software. For home use a simple web interface would be easier. Ask Toolbar, anyone ?


You put the access point in a closet and a repeater in the basement? No wonder you have such terrible Wi-Fi access.

Ralph Grabowski

No choice: the ADSL line arrives in the basement, at one corner of the two-story house.


Thanks for sharing your experience. Although it's a year and a half late for your purpose, readers arriving here might be interested to know that *most* Wifi routers - even across different vendors - *can* be configured to share a single SSID and even smoothly hand off devices between them. Of course setting up routers like this (as true "access points") can be just as challenging as picking out the right hardware for a job. It's a different type of work: lots of research, googling, re-configuring device settings, and a steep learning for the novice. Still - it's worth trying if you don't mind using those tiny pin-hole reset buttons a lot and want to save some money (but not time). +1 for Android WiFi analyzer app. Love it.


You had 4 APs with 4 different SSIDs, AND wireless repeaters for a single floor 50-foot home?? No wonder your WiFi was shit before.

Ralph Grabowski

Four WiFi points for a 1/5 of an acre of land and to handle a house with central heating consisting of large galvanized steel ducts that like to block the signal.
Hence I am very pleased with the power of the commercial-grade Wifi.


Hello, like the other person said you could try a coax converter, but that aside in case you haven't found out how to set the channel manually, you do this from the controller software devices>select the ap>config>radios

The reason why it switched to a different channel upon restart is because those APs are set to automatic by default, but does the channel picking on startup only.

You can even analyze the rf environment from the controller as well in order to choose the best channel for both 2.4 and 5ghz.


One little known fact about unifi access points is you can run a basic unifi co figuration via the unifi app on any smartphone/tablet. It's totally simple. You open the app and to add/manage the AP you simply scan the qr code on the bottom of the AP. Easy Peasy


I must agree with one of the previous posters, four WAP using four distinct SSIDs is bad design. Two common scenarios that are properly designed:

1) If one WiFi access point is acting as the border router, set-up that device in 'router' mode, set your preferred SSID on that device. Then set-up all other WiFi access points/routers in 'Access Point' mode, set the SSID the *same* as your device acting as the 'Router', be sure to set each device's channel to auto (or if you know what you're doing and have done a proper SNR audit of your space manually set the channels to minimize interference). Your wifi devices will now seamlessly switch between WAPs using the same SSID.

2) If you have a different, non-wifi device acting as the border router, set-up all four WiFi access points/routers in 'Access Point' mode, set the SSID the *same* on all four devices, be sure to set each device's channel to auto (or if you know what you're doing and have done a proper SNR audit of your space manually set the channels to minimize interference). Your wifi devices will now seamlessly switch between WAPs using the same SSID.

And don't forget to audit your wifi SNR (signal-to-noise ratio), not just your signal strength throughout your entire space. There are other factors but are more complex and usually beyond nonRF engineers, but SNR is as important as signal strength for stable, reliable, fast wifi. You can have very high signal strength but if your SNR is under 20 db, your connection is going to be slow and likely drop/renegotiate constantly.

Yeah there’s no reason different access points can’t all use the same SSID on a single network. Spread them out so that there’s not too much overlap. Make sure any two adjacent ones are using distinct non overlapping channels (1, 6, 11). Works fine.

Steve Locantore

I am an IT consultant. Though a proper access point is the best solution it is also rather costly. I use the TP-Link powerline devices in my home. It uses your electric wires to build a network of both Ethernet and WiFi access points. No wires to run, just plug it in and configure the WiFi and you are done.

Andy Coulson

I'm pretty sure commercial APs aren't any more powerful that consumer ones - they all have to comply with the same regulations. Why don't you just get some of those ethernet-over-110ac-wiring adapters? Although I haven't tried them, I've actually read that they do a pretty good job getting bandwidth to hard-to-reach areas.

Ralph Grabowski

ethernet-over-110ac-wiring adapters work poorly -- slow, with too many dropped connections. I've tried two different brands of them.

They, in effect, extend the ethernet wiring, not the WiFi range. At the other end, you still need to add a WiFi box, so the problem still is not solved.

A commercial grade WiFi indeed does transmit more power than a home-use one, just as a commercial-grade GPS is more accurate than consumer models.


just install OpenWRT and mesh your APs together to a single SSID like the other poster said. never had problems with that

Ralph Grabowski

While using OpenWRT is a valid solution, it is too technically advanced for most people with WiFi in their home.

Note also that the point of my exercise was to get rid of WifI units down to a single, powerful one -- and not have a mesh of them!

Nick deMolitor

I'd also add people should try to stick with wifi channels 1,6 or 11 to minimise overlap. If somone picks ch8 your overlapping with 6 and 11. If you just pick say 6 your only overlapping with 6. The day wifi 6 (802.11ax) becomes ubiquitous, will be a good day.

Ralph Grabowski

Better than guessing at which WiFi channels are free is to use a WiFi utility on your smartphone, which will tell you which ones are less crowded.

I say "less crowded" because there are in apartments and other locations so many WiFi signals that they tend to crowd each other.

Ubiquiti is not enterprise equipment, it's barely a step up from consumer grade.
