I run a small WISP at the community that I live in, with a Ubiquiti Edgerouter handling the incoming Vodafone fibre connection, and feeding a 5GHz Ubiquiti P2MP network. CPE/AP's are a hodge podge of old modem routers, Ubiquiti and apple gear etc.
The problem I am having is that 4-6 android phones in the village can connect to the WiFi network, but then don't get an internet connection. The same phones work fine on other WiFi connections.
The phones range from older cheap models to a phone that worked fine till an automatic OS update happened to a brand new Galaxy S8+.
I've seen loads of fixes on the interwebby that range from rebooting the AP/router to making sure the date on the phones is right to setting static IP addresses.
The fact that there is no clear "this is the problem and this if the solution" makes me thing it is a bug in some versions of Android and there isn't really a fix.
I was considering switching over to the modem/router that Vodafone supplied and see if that helps, but a lot of the Ubiquiti gear is set up on Static IP's and it would be a pain to have to change/re-do all that.
Has anyone else experienced this issue and have you found a good solution?
