Does the GNex have a problem with wifi G channel 12?
I changed my router from channel 1 to 12 (due to many neighbors on 1) and my GNex wouldn't connect, saying router not found. Neither rebooting nor re-entering the password helped. When I changed to channel 11, it connected. My other devices had no problem with 12, so it's not a router problem.
I'm on unrooted stock JB.
What country do you live in? I believe in the US, you can only use channels 1 - 11. However, if your neighbor on channel 1 is the only other AP around, you can move to channel 6 without issue, as that is also completely outside of the frequency range of channel 1.
The 3 non-overlapping channels in 2.4ghz wifi are channels 1, 6, and 11.
I'm in the US in a very wifi dense area with about 20 APs nearby. I use a software scanner called inSSIDer, which showed the higher channels as less crowded.
My router and other wifi devices, including some computers and Apple devices, work fine on 12. Only the GNex has a problem with 12. It's odd they work on 12, since you're right, 12 shouldn't work in North America.
In any event, I'll stick to 1, 6 and 11.

Hi,
I changed my router's wireless channel to 12 because below that would interfere with the signal of my neighbors' WiFis.
However now my Samsung Tab 3 7'' T110 doesn't "see" my WiFi. Same happens when on channel 13. My computer and my smartphone (a Xperia Mini) have no problem detecting channels 12 and 13 so it must be something with the tablet.
From what I understand, these are European channels and that's were I live.
How can I enable/activate these channels on the tablet?

It depends on WiFi card in tablet. My Tab 3 7inch(T211) has no problems with those channels
Thanks for the reply but that doesn't make much sense to me. How come a Samsung tablet from 2014 can't detect those channels? To me it seems like a configuration somewhere, like with the driver configuration of wireless boards in Windows. There you can choose in what channels the board operates.
Maybe something in the build.prop?
Someone can help me to configure my router Cisco Linksys wrt310N for use with my G4 ?
Look how this router is configured
http://hpics.li/4fb345b
With this configuration, my g4 cant connect to this router.
Who can help more plz
What Wide Channels do you have available. With the 2.4Ghz network, there are three sweet spot channels you 99% want to stay in, being that you are trying to use wide 40 it is best to stay in either 1, 6 or 11 per this picture here:
http://blog.rfvenue.com/content/images/2014/12/2-4_GHz_Wi-Fi_channels_-802-11b-g_WLAN-.png
This could be what is causing your phone not to connect as it is looking for those "sweet spot" channels. Channel 3 can have a good amount of interference if you are in a populated area since you are between two of the main channels.
If i use radio band: standard 20Mhz. I can select 1 to 11.
But if i select wide 40 mhz my wide channel is 3 to 9 and standard channel : 1 or 5

Hello everyone I have an LG G7 ThinQ model number LM-G710EMW,
Now my phone started doing this thing where it wont detect and if it detects it wont connect to SOME 5Ghz AP's.
At first I noticed this on my Home Router, a TP-Link Archer C20 AC, and I thought it was the router so I factory reset it, to no dice.
Then I thought It was the network settings in my phone and I did a reset on those, to still no dice, finally I was like it must be the phone, and I factory reseted my phone, and YET IT DIDNT CONNECT.
A few days later I was visiting my parents house and they have this CHEAP NEXT 5Ghz Router, and it did connect to that one, I was like AHA, IT IS MY ROUTER. That same day I configured a UniFi AC LR AP (a $100 AP) and on that one IT DID NOT CONNECT NOR DISCOVERED THE 5GHZ SSID.
So its not my router.
I have no issues with 2.4Ghz Routers or AP's.
Any ideas?
Could be a channel issue. I've run into this in the past with other phones, where my router would select certain channels depending on the surrounding wireless neighborhood. Turns out it didn't like some channels, especially ones towards the higher end of the spectrum (Channels 161, 165). Perhaps that's the problem. If you're comfortable, log into your router at home and see what the channel width is set to (20, 40, or 80 MHz) and then take a look at which channel (or channel range, depending on the width of said channel) it's set to (most likely Auto). The router chooses channels based on how busy the the neighborhood is. So if you have a lot of neighbors with WiFi networks of their own, it'll try to choose a channel that they aren't using to mitigate interference. Select a channel or channel range that's highlighted in this picture. And I know it says North America, but I believe Europe and Japan use the same channels.
Thank you very much for the reply and a fast one,
I will try to do that then, what do you mean by highlighted?
I usually leave 2.4Ghz to 20Mhz and 5Ghz to 40Mhz.. is this ok?
Is there any better config?
Thanks,

This is optimal in my experience. The 2.4 GHz band is super crowded, so having it set to a channel width of 20 MHz is the only real option. 5 GHz at 40 MHz is good, if you have a lot of neighbors that also have WiFi, this is the best channel width to select for for performance without your bandwidth being stepped on by nearby 5 GHz networks on the same channel.
Because you're using a 40 MHz channel width on your 5 GHz SSID, it takes up two channels, as illustrated in the picture I posted in my previous comment. Some routers don't go up to channel 165, so your only real choices here are 36-40, 44-48, 149-153, and 157,161. You want to try to select a channel that isn't in use by neighboring WiFi networks. two WiFi networks on the same channel can lead to worse wireless performance. The router tries to do this automatically but sometimes will select channels that certain devices are fussy about. Some routers can give you a site survey and show you the other channels in use in the area of your home. If yours doesn't do this, you can download any number of apps to survey the wireless networks in your area instead. Basically, try changing the channel selection to a different choice and see if your phone can connect.

Samen issue heren with g7
Howto fix this?
You need to dial *#546368#*710# in order to enter into engineering menu.
After this follow Field Test-WiFi Test-Ota Settings. Press Disable then Enable.
Now switch on wifi and 5ghz should be available.
Brilliant tip by valyunin. Solved my issue on lg g7 thinq. now my wifi speeds is 800 Mbps and more
Hi!!
I just bought a new tab s4, and I can not connect it to the 5ghz wifi network. It connects, but says connected without internet. The 2.4GHz network connects perfectly.
PS. Sorry for my English.
Same issue.
My tablet is TIM branded.
Same issue, it connects on 2.4ghz but not on 5ghz...
Anyone?
HI peep's mine is connected to 5 GHz and it’s working flawlessly, it’s showing a connected speed of 866MBPS!
Quick questions, did you try a reboot router and Tab S4 once connected to 5GHZ ?
Also are you using separate WPA2 PSK key ?
As some routers can’t handle separate keys, keep the Wi-Fi key same for both channels i.e 2.4GHZ and 5GHZ!
Does it get ip address from the router/dhcp server you have?
I don't have access to a 5Ghz wifi right now. Next week I'll try the tablet and I'll try everything you said. If the new tablet has the same problem of course, I hope it goes well.

See below and bands i have Separate bands!
Galaxy-Tab-S4
dual stack
Galaxy-Tab-S4
device info type 5 GHz
IP address: 000.000.0000 (DHCP)
MAC address: 77:EE:00:FFD:00
I have the same problem and I noticed that it came with the Anroid Pie update! 2,4G is working fine in my S4.
I have another tablet Samsung Galaxy Note 10.1 2014 edition and 5G Wifi is working flawlessly.
Might it be software issue in Android 9?
My basebandversion is T835XXU3BSF4, kernel 4.4.153-16124683 #2 Fri Jun 14 2019.
My Tab S4 was ,finally, updated to Android 9. 5GHz working fine. Both 5GHz and 2.4GHz working fine...
All good here...
I got one coming in the mail and will report back on my success but if you don't get internet trying setting your dns manually to Google's public one for testing. 8.8.8.8 Could also be related to the channel the router is using for 5ghz.

Okay, so I got a new tab s4, and I have the same problem. At the second floor of my house, I don't connect to the 5Ghz wifi. I have separated bands. I tried changing the channel... I don't know what else try.

5GHz WiFi has less range than 2.4GHz, maybe the signal strength is not enough at the second level. Use the lowest frequency band available, move the base unit to a place less obstructed etc. This does not sound like a device issue.

Yeah, I know, the device issue is that all my other phones, computers and devices are able to connect to the wifi. I enabled the smart wifi and it looks like it's going better, the tablet is able to get better download speed.
My phone cannot see my 5ghz Wi-Fi network. It is connected to the 2.4ghz network ok, and I have other devices connected to the 5ghz network.
I have an Orbi Mesh system, and it only gives me 4 5ghz channels to set, 36, 40, 44 and 46. Could this be the problem? My Note 10 can't see those channels?
Mine runs fine on 5GHz, channel 149. Couple yrs ago my phone wouldn't connect to my wifi, I found out wifi router was not set for auto updates, after I switched to auto, it updated and all was fine. I would suggest you check your router settings and make sure is updated. There are programs on google that check wifi signal and show which channels your phone can see and that would be my second step. Program is called wifi analyzer.

The problem is Orbi only has channels 36, 40, 44 and 48 to selct. You cannot select a higher channel, as Orbi Mesh systems use the higher channels for their wireless backhaul. Wi-Fi analyzer can see the higher channels (153) in use (by the Orbi) but cannot any signal on the lower channels, even though my router is broadcasting on them, and I have laptops connect at 5ghz to the router. It's just my phone that can't see the 5ghz network.
I just noticed you're from Indonesia and there are some restrictions on some channels in certain countries for example look here https://en.wikipedia.org/wiki/List_of_WLAN_channels.
Sorry doesn't list your country but gives an idea how that works.
Is your phone specific for your country? If not it may have some software restrictions on those channels and could be fixed with different FW or root. If that's not the case, I'm out of ideas.
