Quantum Radar WIFI not so good

A bulkhead to far

Installed new quantum radar and Axiom mfd.
20í up mast and 25í back to nav station.
Fiberglass deck and plywood bulkhead in between units
WiFi reads infront of bulkhead but not behind.
Spoke to RM but WiFi range extenders etc will not work.
Will have to run Raynet cable in mast.
Sucks

Re: Quantum Radar WIFI not so good

We just installed one, I didnít even screw around with the WiFi, just went straight to the cable.

Friends of ours also just installed one, WiFi only. Itís already back off of the mast because the WiFi was easily visible but would not connect to the display.

Re: Quantum Radar WIFI not so good

I believe the Wi-Fi is best left to powerboats or other installations where the distance from radar to head unit is very small. Cable is always going to be more reliable at any significant distance up a mast.

Re: Quantum Radar WIFI not so good

Interesting. We have Quantum 2 and are using Wifi on a 40" yacht. Radar is at first spreader on Mast. Axiom is in the Cockpit. No issues so far.

"Quantum Radar WIFI not so good"

This is an unfortunate title. You casting significant disparity on a product, however it is the limit of the technology (wifi) and your installation which are at the root of the issue.

You have a fairly long distance combined with solid material interference. This really has nothing to do with the Display or the Array.

Quantum radar and Axiom works very well on my Nordic Tug. Short distance, yes.

But fwiw: it did not consistently connect and stay connected when first installed last May. After I downloaded and installed a software update it had no further connection problems.

Re: Quantum Radar WIFI not so good

My quantum radar is great on WiFi, just above the first spreader. Plotter is in the cockpit. Use the tablet below, connected to the plotter. Can even see the plotter from other boats far away. perfect.

My Bluetooth fusion stereo range is not good using one phone, but great with a different phone. I wanted to blame fusion.

Understanding a products limitations when selecting and installing, priceless.

Re: Quantum Radar WIFI not so good

I would not rely on wifi for any critical system.

Re: Quantum Radar WIFI not so good

Ran data cable down mast and still could not connect with the MFD.
Pulled scanner down and placed it next to the MFD and hooked up with WiFi.
The signal strength with a 2’ distance was only 1/4 , -127 dbm.
Tried a short data cable which then worked.
Contacted RM who suggested updating the software version in both units.
Brand new unit had v3.5.
Waiting for the new micro card to be shipped down to Mexico.
Will let you know if that works.

Re: Quantum Radar WIFI not so good

Worked fine on ours. We have a replacement (Hurricane Harvey) that we are installing in 10 days. But we don't expect any problems.


Quick edit: Are you SURE you configured it correctly? We DID have a configuration problem with ours the first time.

Re: Quantum Radar WIFI not so good

We hard wired our quantum radar because I donít trust wifi connections that could have a problem at a critical time when sailing offshore.

Wifi is great when it works, but when it stops working, I have trouble sorting things like that out.

Our prior radar was hard wired and worked without a problem since 1993.

I have an uneasy relationship with electronics, and find equipment glitches very frustrating.

Re: Quantum Radar WIFI not so good

Installed the new software version but WiFi signal strength didnít improve.
The good news is that it now works on the hard wired data cable.
