Hi there

I can connect to my router if I choose a 802.11 b/g or b/g/n mixed mode in the router itself. With 802.11n I can't connect. Bug or PEBKAC?

there's also something like country frequency settings, i forgot the name of it, perhaps check if Jolla is in the correct regulatory domain?

I think you are on the right track. Maybe the router switches to 5GHz in 802.11n-Mode (There may be a setting in the router to turn this off, search for something like "automatic frequency selection"). The Jolla only supports 2.4GHz.

i thought a-mode was 5GHz? afaik bgn mixed mode is 2.4GHz only. perhaps separate n-mode has 5GHz possibility, but i doubt this is the problem.

even in 2.4GHz there's quite some channels (check for the ones that n-mode adds extra on wikipedia and look at dmesg for wifi regulatory domain)

b & g are 2.4GH, n is 2.4 and/or 5 GHz (cheap devices support only one frequency at a time, the better ones can do both at the same time) I have a cheap 802.11n-capable AP, which always takes the 5GHz range if I let it choose, because 2.4GHz is crowded nowadays.

@Cmdr_Zod i've seen if you choose mixed mode that it always uses 2.4GHz range, unless device is capable of selecting n-mode alone
