Just registered here to report some issues. I've never used Gargoyle before so bear with me.
I started with a very old prerelease version that would not save Wi-Fi settings. Then I found a newer version, which did work. Today I noticed RC3 existed (and RC1 and RC2
My router is a TP-Link Archer C7 v4.
With the pre-RC1/beta version I had installed, I added gargoyle-router .com/packages/gargoyle-1.9.1/ar71xx/default as plugin source so I could install "WiFi scheduling for Gargoyle". This seemed to work (at least I could set up everything and manual disable/enable worked). In beta version this wasn't available anymore in default plugin lists. It would be nice of this package could be re-added to 1.11.0 so it's possible to turn off Wi-Fi during the night.
But in RC3 I'm unable to install these due to all packages being detected as 10MB+ (which should mostly all be around 10KB I think). So I've now downgraded to RC2 and that is detecting the sizes correctly. So that's one issue I've noticed.
Another issue, if I add 'gargoyle-router .com/packages/gargoyle-1.9.1/ar71xx/default' as a source, I'm unable to remove it. I would like to remove this source as I noticed gargoyle-router .com/packages/gargoyle-1.10/ar71xx/default/ exists as well.
One thing I do miss in Gargoyle is a PPTP server and/or HTTPS proxy server. Not a huge miss but with the other privacy related options (OpenVPN and Tor) it'd be very nice to have
The advantages of those is that pretty much everything supports PPTP and HTTPS proxy. OpenVPN is limited.
As far as the rest goes, it looks very solid and I really like the offered features. It's a much more accessible firmware than OpenWRT, which I had installed first but didn't like at all due to the 'way too much to configure' mentality. I don't need to be able (and want to) configure every possible thing.
Hope this helps, if you need help with anything, please let me know and I'll try my best. Thanks for all the hard work on this project, it's appreciated
