i have a nexus 7 (first gen) that is rooted and running 6.0.1 quite happily

 

except - it won't connect to the ubiquiti wireless, but it will connect to the billion wireless

 

 

that is itself is annoying, but more perplexing is that there is another identical model and firmware that connects to either wireless happily - let's call that one "good"

 

my presumption is the ubiquiti has mysteriously got the shits with the "bad" one, but i can't for the life of me figure what the spell that has been cast might be

 

the "bad" nexus will report "saved" and sometimes reports "network connection failure", but i'm stumped - from memory even a re-flash didn't get it to co-operate

 

 

any clever suggestions ?

At least your OS is up to date.  I rooted mine and it took the first update fine but has since failed to update with any OTA, suppose I should look at manual flash options.

 

I would guess you've tried the obvious, Windoze and Android both seem to occasionally get their shit in a knot over an AP and just deleting and letting it redetect then re-enter the password often fixes it with nothing else needed.

 

The other thing that comes to mind is that especially with rooted devices you can do network shenanigans like changing the MAC address, and probably other stuff too which some APs might not like (?)

 

Aside from that... NFI.  Maybe if the "bad" router has IP reserve options based on Mac address you could try something there.

i'm no master of networks, but i can usual;ly fudge the setings

 

the problem here is that the doppelganger device is quite perfect

 

the other one has been dropped my mr 14 and has a few peripheral screen cracks, but it still can't explain to me why it is friends of the billion, and crap with the ubiquiti

 

at a pinch i can run 2 ap's, but i don't want to have to do so

 

 

bleh !  i'm off to bed - it was easier when i just thought it was broken... but now i'm on a mission (but no more tonight)  :(

You checked the firmware on the good and bad ubiquiti are the same? Maybe it's firmware issue on the router.

Hrrm?  I think it's only the Nexus 7 where he has 2 like devices, then there's 2 seperate branded Wifi AP devices.

The devices might be identical but they might have different firmware installed.

I'm only giving him another thing to look at in case it is that.

You mentioned "good and bad Ubiquity" - there's only one of those.

Got it, I read he had two Ubiquiti and not two Nexus 7.

glad you people are happy

 

i still have one misbehaving nexus 7, and to add confusion, yes i do have two ubiquiti ap's, but one is in a cupboard as a spare / potential addition to the home set up

 

there uis still no understanding as to why the "bad" nexus can't talk to the ubiquiti even though it can to the billion - i wonder if i had inadvertently blacklisted it on the ubiquiti, but can't seem to figure out where or how, as the router assigns random ip addresses and i don't think i can block mac addresses on the ap (but i might have...)


ummmmmmmmmmm............

You tried putting a static address on bad nexus when connecting to the ubiquiti instead of using a dhcp address?

I suggested that sort of thing already - as in set a reserved IP at the router, based on Mac addr of the Nexus.
