DESCRIPTION:

Xperia 10 is unable to see Wifi networks which are transmitting throught channel 13, is there an solution! This means the phone is unusable.

Did it work when it was running Android?
Calling a phone unusable with the loss of one WiFi channel seems a bit harsh.

When i do iw reg get i see my phy#0 is set to US, and i guess that would have this effect.
Is it the same for you?
I can’t immediately find how to change it (iw reg set SE does not change this), but i’m sure someone here will know.
