WiFi interference on Siglent oscilloscope

Im a curious person too so it would be nice to know indeed. That said I hope I wouldn’t get power like interference if a neighbour installed it - but in a block of flats may be more relevant indeed.

Ah, I thought I read somewhere that DHCP was a better choice for the siglent. To be fair there’s is nothing wrong with dhcp, a well designed device should perfectly work with that.
If the issue is the changing IP, then that does not happen on my network as each device is bind to its own MAC address in my router, that is, it keeps receiving the same IP over time, it never changes.  I like this more than set a fixed ip on each one of my devices. This way I have central control on the ip scheme.

I can still try locking the siglent via it’s own interface but the thing is that it worked fine with the previous wifi adaptor and the same exact configuration 🙂

Shall give it a go though, thanks.

Just a quick follow up, the Mesh network with the spare FritzBoz! works like a charm. The feed is more or less the same speed I had before but ping is much more consistent - mostly 1-2ms. Also, my Devolo Powerline adaptors are now on sale - they're not cheap to buy so I'm going to make some money out of them.

Thanks for giving me that idea!

you can disable WiFi interface in the router settings. I had similar issue with operational amplifier, when it works near WiFi router (about 1 meter away), I got about 30-40 dB noise floor spikes within 0-150 kHz bandwidth, it happens about once per second or even more often. Disable WiFi interface in the router helps me to fix that issue.

But the thing is that I need the WiFi! :) That is why I got a Powerline with WiFi AP on it.

That said, I believe I tried with or without, different sockets and nothing ever worked. The socket I installed on purpose close to the DB (I thought it would give me a better signal) was giving so much interference I couldn't listen to the radio.

Years ago I had Powerline (different brand) in my Home Theatre and - despite not really performing much better than standard WiFi - I had the same interferences in my speakers.

So I guess this is lesson learnt. No more Powerline.

It's not the WiFi signal that is causing the interference on the scope, it's the powerline box. They use all the dirty tricks in the book to get a signal from one box to the other and they should be made illegal  :box:
