Comment 17 for bug 1727237

So, after looking at it more, it seems the issue with Datavalet is due to EDNS0-enabled queries failing to be captured and rewritten by the captive portal. It might not in fact be the same issue as for, though the wireless hardware comes from the same manufacturer.

I have a tentative patch ready for; I will adapt it to work the same way for, and I'll put all this in a PPA for testing.

Unfortunately, I haven't found a location that uses; so we will need to others (if you remember where you encountered such a network) to make sure it really works correctly before uploading to release.
