Noticed that on my 12.2 with the latest FW the high wifichannels 11,12 and 13 are not availble to connect with my router My note 4 doesnt have that problem Finds my router on channel 13 without any problem.
Is this hardware and normal. And is there a way to have those channels availble

Are you in the US? If so, then channels 12 and higher are not "technically" available in your area, they are for non-US applications. Some firmwares restrict higher certain based on channel and some do not. If you are ine US, then then you should set your router to use a channel between 1-11 for best compatibility, if you are outside the US where these channels are used, make sure you have all your regional settings correct and the ROM version is correct for your region.

I am from Holland [The Netherlands] Its the Dutch stockrom witch is only rooted. I was aware of what you wrote that indeed in the US you cant go higher then channel 11
So i was thinking is this a hardware problem? Firmware problem? Kernel problem?
Well its not really a problem but the lower channels are full with other users so I was thinking i use the 12 or 13 as i do on my Note 4... But the Note 12.2 cant..

This would be a firmware issue, I would contact Samsung support via the web.

wow! I just had this problem with my US bought Surface RT when I returned to my apartment in China. My router was set to channel 13 and I couldn't figure out why my smart phone was connecting but my surface wasn't even detecting my wifi, even though my surface is so close to the router the antenna is almost touching my surface!
I had to borrow a friend's laptop to change the channel, becuase the surfafce has no ethernet port and I bought this to replace my laptop.
So you are not imagining anything, I have the same problem.
I think its law in the US that devices sold there cannot have support for channels 12 and 13 (the frequencies allocated for those channels are allocated for something else in the US I think).
You probably can't re-enable it.
Probably not an issue either. Most devices I have seen here in the UK default to auto or channel 1. I've had american relatives come over and their laptops have connected to UK routers fine.

Nope. If you buy a surface in the US, it is limited to US frequencies.
and there is no way to reflash the firmware of the Marvell Avastar 88W8797 WiFi chip?

Most likely write once memory, ie, cannot reflash it.
I bought my Surface RT in the US, but am using it in the UK, so have the same problems.
Chances are it could be enabled with a new driver... most wifi cards in laptops are multi-frequency and are just enabled via the driver or firmware.
Getting a new driver onto the RT might be a problem though.
Is someone able to upload the driver files from their European system? Any files that show up under "Driver File Details" in Device Manager.

I do not believe there is any law in US against using 12 & 13 . All wi-fi routers are able to use them. I had this issue the first time last week when my router auto tuned to 12 and my Surface could no longer see the SSID but my phone and wife's ipad had no problem.
The FCC may permit their use at very low power, but I'm not even sure about that. There are a number of areas of radio communication where different "channels" (frequency ranges) are permitted in some countries but not in others. In many cases, devices manufactured in the US either can listen but not broadcast on those frequencies, or can only use them after put in "international" mode, but sometimes they are able to do so anyhow and it's on the user's head if they cause any interference.
Hi,
i just received my nexus 5, but i couldn't find my wifi (i found others and could connected to them) . After i switched the channel width at my router from "Auto 20/40mhz" to "20mhz" it worked fine. Does the Nexus 5 doesn't support 40mhz or is it just my device?
Thanks!

I'm going to try to test some various little wireless things that are going on with it when mine comes in today. For one, they are not allowing the use of channels past 11 which is most likely by design for US spec 802.11B/G.
If I were you, I'd try a few different A channels (52, 56, etc.,) with the 40mhz bandwidth on. I know in the newest code for Cisco AP's I work with, they've gotten a little wonky due to FCC rules for devices with multiple radios.
Has anyone had trouble with connecting to 5GHz networks with the 2012 GT8010?
I've been unable to. I can see the network but always get authentication issues. This occurred with the original 4.1.2 rooms and now with omnirom after a full reset
My other devices such as a laptop and s4 have no issues...
2.4GHz is just fine even to the same router with the same security settings. Disabling security., dropping g down from ac to a doesn't help nor does switching channel

I have not had any problems personally. I'm running stock not rooted. I have heard other guys having problems though. Sorry I can't help
If you're rooted (or even just have a custom recovery) check here. Turns out that the wrong WiFi config file is being used in US-based units so 5GHz DFS channels won't always work.

thanks. interesting to see if I have issues in those files, but I am actually in the UK in any case.
I tried copying the *mfg* file to *txt* - manufacturing? default perhaps? this had cc=ALL instead of UK, but I figured why not
No difference.....
So followup question - could any UK users post their files from /system/etc/wifi/nvram_net.txt*

and yes I know the mac code is in there - skip that
Does anyone ever got more than 150 mbps rate ? I mean the connection rate between the tablet and router, not some speed test result. On 5Ghz I get 150, on 2.4GHz no more than 72 mbps. I tried 3 different routers, never got more then 150 mbps, and 60 up/60 down in speed tests.

No, and I wouldn't be surprised if that's intentionally set via the WiFi firmware; the WiFi chip is connected to the Exynos via a 50MHz bus that's 4 bits wide, so your effective thruput wouldn't ever be higher than ~180Mbit/sec anyway.
I got myself a note 5 from t mobile few months ago.
I don't live in the states but it does work but not perfectly. When I'm on a regular 3g Antena it says I have 4g and when I'm really on 4g it shows 4g LTE. I also have some trouble with reception when other global devices work perfectly fine.
Is there any way to flash a global note 5 modem on my t mobile note 5 so that it works better?
And if so can someone provide some links and info? Can't find anything about that issue.
Thanks ahead.
Anybody?
Depend on wich bands your phone can get, not modem. There is no international version of note 5 n920c/i etc is international, yes, but no idea if exist a international firmware for these device whit no operator bloatware.. these devices n920i,c etc is for regions, there is no official internatonal version of note 5

Yeah I know I can't install the international firmware but there must be a way that I could add/unblock more bands by software. All versions are identical in their hardware.
I don't care about the carrier bloatware I just disabled or remove it using titanium /lucky patcher

Try this app (you need root acces for extra settings)
https://play.google.com/store/apps/details?id=com.cc.signalinfo
Open the app, go to additional info/ device information and there you can see more in right side. Pres and select band. Test it and let us know

Omg! I don't know. Maybe you need work whith secret codes on dialer and find the band you want. I don't know how, but you can find on here or searh a web

Hi all,
I need your help. My mate 9 is mha-al00c00 model and use the last update b173. It cannot to detect wifi 5ghz of tp link wdr8500. The range channel of this router is between 149 and 165. How could we change the wifi country code on the root of android 7.0? Someone has the same issue.
Thanks
Try the lower channels (36-64). Fixed it for me.
Sent from my MHA-L29 using XDA Labs
These channels 149 and 165 have fixed by the tp link factory. I cant try the lower channels
That would be the most absurd thing I've ever heard. What model is it?
Sent from my MHA-L29 using XDA Labs
Tp link wdr8500
Could we open all channels on mate9 to see wifi 5ghz?
In a 5ghz, i cant try channel between 36 and 48. I think i have one problem with the current firmware under dfs channels. Could we try manually to change a channel on mate 9?

The 5GHz channels for WiFi are not standard across the world. Some countries use part of that frequency band for other purposes including government services. That's why WiFi routers and phones sold in some regions have certain channels locked out.
If you import the router and phone from different regions then you could find they can only talk to each other on a limited number of channels. There are ways to overcome this, but you might then find you are using channels that are not permitted in your country and/or suffer from interference.

Up until B126 my Mate 9 was working fine at the higher 5.0GHz frequencies. It started giving me trouble when B138 came out so I simply dropped to a lower channel and that did the trick.
Have you checked if DD-WRT runs on that router?

My mate 8 was choking on 2.4 ghz... and i found your answer. i got my phone from china and i switched on my router on 5G that was seen for everyone (channel 40 - for europe and my mate from china...). Finally my mate has seen 5g network... and it is blazing storm fast now!
finally i can be happy having around 100 mbps instead of 30 mbps.
Ty mate for this link, it was so obvious but i dont have enough knowledge to see what is up with this wifi channels!
Hello,
I there is someone out there can help me.
My mate 8 can see my network 5ghz but no way it can connect to it. My other devices, laptop, Fever smartphone have no problem to use that frequency.
Thanks
Same here in France
