just out of curiosity; what are the benefits of the WA-webinterface over a native client? (yes, e2ee yadada, but really)

I can run it in a firefox tab, and I don't have to install anything or do another login/sync.

good point, thou telegram also has a (ordinary) web-interface https://web.telegram.org

You can't use it without your phone connected (to the same network), which in my case is a no-go.

this!

consumer and soho routers are usually bridging wifi and lan together whereas professional and enterprise tend to run seperate networks, mostly for security reasons.
