Skyview trouble

Your FF is currently offline so I can’t check it at the moment.
Does the problem happen if you try a direct ethernet connection rather than wifi?

There were problems with a provider.

I think you’re right. The problem is Wifi 2.4 GHz. This is a very noisy 2.4 GHz band.
Ping to the router (ie one hop) can reach more than 100 ms.


I use 5GHz band if a device, like SMART TV, allows it.
This is a temporary, compelled place of installation. In the future, the device will be installed in a place with a clear horizon.

Thus, it can be assumed that the latest versions of the dump1090-fa have a requirement for connection quality.

Yes, if the connection is so bad that you can’t move 250kB (size of jquery-ui) over TCP then the web interface won’t load.

maybe you could lighttpd mod_compress give a try. server-side output compression often works great over lame connections when the content is highly compressible like scripts, css and html …

edit: but i never tried this with dump1090 and lighttpd - just a very old memory from the times when apache and a 28.8k modem was the standard :slight_smile:

gzip on used frequently in Nginx. I think this is reasonable when using a large amount of scripts.

as i said i never tried it with dump because i have no need for. my aicraft.json that is loaded every second has 75kb → 4,5mb/minute → would be zipped just about 20% of original size => 3-3,5mb/minute less traffic. in theory - that’s why i’d try this on a super-lame connection you have …

edit: Docs ModDeflate - Lighttpd - lighty labs

The size is mostly irrelevant because the scripts don’t change, so the browser will have them cached. Negotiating gzip/deflate/etc isn’t a bad idea but it’s not going to have much of an impact once the initial problem is fixed. Of course you’re trading off CPU on the Pi for bandwidth.

I found a more efficient way to reduce the amount of transferred data - Virtual Radar.

Have you assesed modeSMixer2? Which is more efficient, VRS or modeSMixer2?

I plan to install it on my TL-WDR3500 router -
OpenWrt Barrier Breaker 14.07 MIPS ar71xx (TP-LINK TL-WDR3500/3600/4300 only): modesmixer2_mips_ar71xx_20150323.zip

Virtual Radar was chosen because I saw how it can be customized (like http://planeradar.ru/virtualradar/desktop.html). In particular, the use of a maps.

I lost my Skyview browser also. Turns out my Pi’s IP address had changed… not sure why … I thought I had it set as a static IP. There may have been an Ubuntu update that changed the IP settings back to dhcp. I went to the public website, logged in, and saw my local IP address there and … it was changed to this new address. Obviously on the Pi, I could have looked at the ip address … ip a … or whatever means. Just never occured to me that it might have changed by itself.
