XZ dont see 5Ghz networks

[DrontTula1]

Just bought new Xperia XZ dual, and it dont show any of my 5ghz networks (channels 149 width 80, 153 width 20). Old xperia z1 works with both networks without any problems, just as other 5Ghz devices (ipads, laptops).
Any suggestions how to fix it?

Thank you.

I will ask local support team, hope they will give developers actual regulations, and this strange issue will be fixed

[DrontTula1]

Nope, they don't help. Just advise me to set WiFi mode strictly to 802.11n and use channels below 10 (facepalm).

Dude, the same problem with Sony Xperia X Perofrmance Dual. With SIM (megafon) I can use onle 36-64 channels, without sim - any channels I left feedback about it in russian support in jule, but still there are no any solutions from sony, they only advice to use low channel connect

What a pity

Anyway, support team, I have found what this prohibition was some years ago (2007-2011). Looks like somebody have read outdated regulations documents.

So, please, fix it.

PS. Russian support team is absolutely amateurish

@DrontTula

I've forwarded this internally a couple of times with the same response but i'd be happy to do it again.

If possible, could you send me the source of the information you found that i can refer to?

Of couse.

First of all, I finally found the document where frequencies 5650-5850Mhz was not approved - Приложение № 2 к решению ГКРЧ от 20 ноября 2014 г. № 14-29-01 . But I'm sure what there was a stupid mistake, because there was a document Решение ГКРЧ от 15 июля 2010 г. №10-07-02 from 15 july 2010, that allow to use freq 5650-6425 Mhz until 2020.

In 2015 somebody finally noticed this mistake, and regulator issued another document Приложение 1 к решению ГКРЧ от 29 февраля 2016 г. № 16-36-03 in 29 february 2016.

So, i think this was a stupid bureaucratic mistake, and since 29 february 2016 these frequeinces are absolutely officially allowed to use.

Thanks!

I've forwarded it again along with the information you provided.

[DrontTula1]

Thank you!

Hope this information will be enough to fix this issue.

Can'u do the same for Sony Xperia X Performace? It has the same problem.

I received the reply that we are unable to support these channels due to EAC regulations that can be found in this document:

@Desperanto

I forwarded this for X Performance as well but the answer is the same for this model.
