Mark,

If you were previously seeing signals in the -91 sort of range, you were on the hairy edge of seeing anything at all. Below around -90 you’re unlikely to see anything or get any sort of connection. If you do, you’re lucky.

The weather and many other things impact the signal a bit. We usually see winter signals be a couple dB higher than summer.

So, I think it’s entirely likely that if you were previously seeing signals down that low, that the conditions are just a little different and there’s not enough there.

Hi Mark,

When I configured the QRT 5 International this month. Only three amateur radio frequencies are scanned: 5.880, 5.9 and 5.92.

In WinBox terminal command
/interface wireless monitor 0
will show the frequencies and bandwidth being scanned if no radio is found.

If a radio is found you will see the details like

I have this 25/27 dB  MikroTik LHG XL HP5 device that I can move around Tumwater (south Olympia) and measure the signal from Capitol Peak at various places at around 10 miles.
The last two nights I have reset and completely reconfigured the device and I still cannot register any signal from Capitol Peak in several locations. 

After I do a reset, and before I reconfigure the routerOS, I see that it scans all the regular 802.11 channels and registers a whole list of local APs. Then I go on to finish inputting all the settings and it becomes silent. I can't get a single 5.8 Ghz signal to show up from several locations around my local area.

So has something changed? 
Do I need to apply some other setting? 
Did HAMWAN suddenly change all their frequencies? (smirk)
Is Capitol Peak asleep? (smirk²)

I could assume that somehow my device has crapped out, after less than a year an no real usage, ever. I used to get -91dB and similar from scanning at my home and at the local DEM, but now nothing. It shows all 6 channels enabled, but a scan shows nothing.

Is there a way to test this thing? Could I enter an additional standard USA 5Ghz channel and see my own 5Ghz wireless show up?

Thanks y'all.
