I have a BelkinN600 and switching to 5ghz is not an issue for me as well.

Do you have your Wifi frequency band settings on your N10 to run auto or strictly 5ghz? Maybe its checked at 2.4ghz?
[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
Thanks for the replies.

jjdevega - I've tried this setting on both 'Auto' and '5 GHz only' and none of the 3 tablets I have recognise my 5GHz on either setting.

It seems improbable that I've got 3 tablets with exactly the same WiFi fault, so I'm rather stumped as to what's causing this.

Would both of you mind letting me know if inSSIDer shows your 5GHz networks in the spectrum view?

Thanks.

[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
Okay, I've been digging deeper into this and I've turned up something interesting.

None of the Nexus 10's I have here seem to work on the 5GHz channels numbered 100+

My network resides on 100 and 104 usually, and all my other 5GHz capable kit can use these channels just fine.

If I set my router to one of the lower channels (I can force the router to 36, 40, 44 and 48) then the the N10's see it fine.

Can I ask what 5GHz channels people are using? Does anyone have an N10 using channels 100+ ?

Thanks.
[Nexus 10 Q&A, Help & Troubleshooting] eander315:
Mine is using channels 36 and 157. Both are Asus routers. I can see my neighbor's 5Ghz also on channel 157. Time to switch channels I guess.
[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
Thanks, that's really interesting :)

I'm in the UK so can't use 157 - it's not a licensed channel here and so is disabled on the router :( Whereabouts are you?

It's curious though - all the channels that require dynamic frequency selection (and transmit power control in Europe) seem to be inoperable on the N10 (channels 52 - 64 and 100 - 140)

36 - 48 are only licensed for low power use, and don't quite provide the range I need. My router chooses 100 and 104 when set to auto and uses them at full power, and this provides the range I need. It's a shame the N10 doesn't seem capable of operating on those channels.
[Nexus 10 Q&A, Help & Troubleshooting] eander315:
I'm in the States (Houston, TX). Unfortunately I can't use 100 or 104. I just moved my second router to 149, the lowest of the block of channels above 100 available here. I can't think of a way to test your scenario here. Hopefully someone from the UK will chime in.
[Nexus 10 Q&A, Help & Troubleshooting] espionage724:
I can't remember the exact conditions, but I was able to not have my 5GHz network shown on my Nexus 10 one time, and have it shown another. I was messing with channel frequency though, but can't recall numbers used.

[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
I am using channel 153 at home. I dont have channels around the 100~ area in the States, those are for other countries.
[Nexus 10 Q&A, Help & Troubleshooting] espionage724:
Internet speeds shouldn't affect it; it's what wireless channel your router is using for 5GHz that matters. May want to play around with different values.
[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
No worries, thanks for trying. Out of interest, do you know what channels your router would select in automatic channel selection mode?

Thanks, that's consistent with what I've discovered. It seems there are indeed some channels the N10 won't work on.

Thanks. After experimenting with different channels I have my N10's all working on these channels now.

No, those channels are all licensed for use in the US.

With 5GHz WiFi, a lot of the channels require the use of DFS as part of their usage license. These are 52-64 and 100-140. Because the selection of these channels must be dynamic you cannot force a standards-compliant router to use them, which is why they cannot be manually selected. They can only be selected by the router its self when it is in automatic channel selection mode. In Europe those channels also require the use of transmit power control (TPC).

It appears that the Nexus 10 will not operate on any of these channels, however the reason for this remains unclear.

That means the N10 seems to only operate on 4 of the 19 licensed 5GHz channels in Europe, and only on 9 of the 24 licensed channels in the US.
[Nexus 10 Q&A, Help & Troubleshooting] eander315:
I haven't ever set mine to automatic. I manually set them to opposite ends of the spectrum, but I could try using auto to see what they do.

Thanks to Rusty. On my DD-WRT cisco e3000 nothing worked except channel 40 and 20mhz on 5ghz. 2.4ghz seemed to work perfectly fine.

What a pain in the ass. My Galaxy Note N7000 phone works on any 5ghz channel.
[Nexus 10 Q&A, Help & Troubleshooting] bioorganic:
This is probably a failure of Google marketing. The fact that you did not mention your router firmware, chipset, or specific settings, indicates that you probably don't have a clue about the details of wireless networking. I doubt that you've received 3 defective devices. More than likely, your router configuration is not compatible with your N10. Google shouldn't be marketing their nexus devices to average consumers. I spent a few hours tweaking my dd-wrt atheros based router to get a good connection with my N10 at 5 ghz. The Nexus devices push bleeding edge hardware and software. They probably shouldn't push these devices on the average consumer. Sorry if this seems harsh, but it's the very same reason why I wouldn't suggest a Nexus device for my parents.

I'm posting this via a 5ghz connection. With three devices not working, odds are the problem is from your router config. what's your channel bandwidth set to?
[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
Thank you for your condescending tone, and for not bothering to read the whole thread.

If you'd bothered to read the thread you'd notice my observation, after quite a bit of testing, that there appears to be a range of channels that the N10 will not operate on, which at least one other person has been able to verify. Again, if you'd bothered to read the thread you'd know that.

If anyone can get a Nexus 10 to run on the channel ranges I posted previously (52-64 and 100-140) then I would be very interested in looking at those results. As far as I can see, people only have them working on channels 36-48 or 149-165.

Thanks, what channels? Can you get a connection on channels 52-64 or 100-140 ?

Nope, odds are it's a problem affecting the Nexus 10, as I have a whole bunch of other kit here from Samsung, Apple, Dell and Sony that all work fine.

Thanks for the post though, and I'll put the same question to you - can you get a 5GHz connection on channels 52-64 or 100-140 ?

[Nexus 10 Q&A, Help & Troubleshooting] TonyApuzzo:
FWIW, on my Asus RT-N56U the following are allowed:

USA (channels 36,40,44,48,149,153,157,161,165)

Europe (channels 36,40,44,48)

Taiwan (channels 149,153,157,161)

China (channels 149,153,157,161,165)

Japan (channels 36,40,44,48)

Debug (all channels 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165)

UPDATE: I have tested all the channels available in DEBUG mode on my RT-N56U and found following:

Working: 36, 40, 44, 48, 149, 153, 157, 161

Not Working: 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 165

Channel 165 is "legal" in the USA but doesn't work on the N10. IIRC, according to Wikipedia, 165 is under some question as to whether or not it is legal due to bleed issues, so perhaps Google is just being conservative. From what I can tell, at least in the USA, Google is being accurate with their marketing of the N10 as being 5g capable. More experimentation would be warranted in other regions before we can say definitively yes or no for those regions.

I did this experiment using the app "Wifi Analyzer", with settings configured to enable scanning all the 5g channels. I disabled 2g in the settings and then monitored the N10 via the view "AP List". Then, went to my router's config page on my PC and flipped through all the various channel settings. My router is running the Padavan custom firmware which gives more access to channels than stock firmware.

I didn't test other region codes on my N10, and frankly, I'm disinclined to. I didn't want to run my router out-of-spec for more than the ~30 minutes it took to do this test.
[Nexus 10 Q&A, Help & Troubleshooting] bioorganic:
Rusty2k,

I sincerely apologize, I was being an ass. A few beers seems to do that to me. The N10 WiFi chipset doesn't seem to play nice with a bunch of routers. There's a ton of posts about WiFi dropouts on another thread. I haven't been able to confirm the Broadcom chipset in the N10, but I suspect it's one of the new WiFi/Bluetooth/NFC combo chips. As with everything else in the N10, it's bleeding edge hardware and the drivers are half-baked. That being said, I had to upgrade my routers firmware, with the most recent atheros driver, for the N10 to work flawlessly on 5ghz. Even after updating, I have to explicitly set the channel to 36 or 153 if I want 40mhz of spectrum. A bunch of other channels will work if I explicitly specify 20 MHz of spectrum. I have several other 5 GHz devices that work with "auto" settings on the router and with earlier versions of the routers atheros chipset drivers. The N10 is picky, and I suspect it's due to very immature drivers. Again, sorry for my rude comments.

[Nexus 10 Q&A, Help & Troubleshooting] RobRoy:
Hi,

Just a few quick notes and questions.

Using a N10 tablet and ASUS RT-N66U I also have o issues with 5 GHz.

Havent checked yet which channels allow 40Mhz vs 20Mhz, but could try that.

I am limited to what my router allows me to set:, from recollection it is 36 to 48, 149 - 163?

Limit is dur to combinbation of Australian regulations and router.

Just a side note, testing revelaed that the N10 only allows 20MHz on the 2.4 GHz band.

BTW one questiojn I have is how does the N10 know which region it is in and therefore which channels it is allwoed to use?

Can't recall any settings in relation to that.

Cheers.

[Nexus 10 Q&A, Help & Troubleshooting] TonyApuzzo:
I'm not 100% sure how it works for the N10, but most Android devices require a change to a secure DB or to the build.prop file. Generally this is pre-set based on the market where the device is being sold. I don't know of any devices that use GPS to determine the allowable wifi bands, although that would be a sensible feature.

[Nexus 10 Q&A, Help & Troubleshooting] bioorganic:
I apologized for being rude, which is more than you can say for a lot of people on here. My primary point was that the original intent of the nexus brand was to push the most current software on bleeding edge hardware. With the N7, they changed all of that with legacy hardware and mature software. The N10 got back to the original intent of the brand. new hardware in almost every aspect, and new software on top of that. I expected that coming in, and didn't RMA 3 times when my 5 GHz wifi didn't work. there's plenty of bugs, but we've been living the A15 dream for 2 months with hardly anything competitive on the horizon. like I said, I'm sorry for coming off harsh, and should't have done so, but if you want to pound your chest and threaten the "ban hammer" go right ahead.

I just noticed this problem with my N10. I changed the channels on the router and the ONLY channels that work are the low ones (36-48) and I can't even get the 149-161 range to work.

If you cannot even see 5GHz networks when you previously could on another ROM, then the new ROM itself would have to be what has the problem and its dev would need to fix that.
[Nexus 10 Q&A, Help & Troubleshooting] Rusty2k:
Sorry for not coming back to this thread for a while, I've been very busy with work unfortunately. I'll try to write a proper summary soon when I have a bit more time, but my suspicion at this stage is that the low level drivers for the WiFi simply don't implement DFS as the only issues are on channels where DFS is mandatory.

Now, given that the Nexus 4 exhibits exactly the same issues with 5GHz WiFi it is my belief that Google simply hasn't licensed this portion of the code from Broadcom, in much the same way that they wren't prepared to pay for licenses to the CDMA binaries that resulted in support for the 4G Galaxy Nexus being dropped. I can't see any other reason why DFS would simply not be implemented on the Nexus devices.
[Nexus 10 Q&A, Help & Troubleshooting] mrvia:
I have the same problem only channels 36, 40, 44 and 48 will work. I looked to Wikipedia to find the the reason.

List_of_WLAN_channels

In Germany we can use much more from 36 to 64 and 100 to 140. But the 36 to 48 can work without TPC (transmit power control) . I think currently the Nexus 10 does not support TPC. Maybe that is the reason why the device has switched these channels off.

Is anybody there how has contacts to the Google Nexus teem or Samsung?

The best way is to ask for feature request for all allowed 5 GHz channels support by enabling TPC and location service on device.

Best regards
[Nexus 10 Q&A, Help & Troubleshooting] mrschwartz:
this issue is completely due to the DFS channels. In NA and EU (and generally everywhere else) these are channels 52-140. Not many retail routers have these channels available. DFS certification is mostly an AP side qualification. DFS channels are shared with radar, like weather radar and other sources. For 5ghz wifi to share them with weather radar, before they transmit on any of these channels, they must first "sit" on the channel for 60seconds and just listen for radar pulses. After 60seconds with no radar detected, then the AP can use the channel. After starting to use the channel (transmit beacons), the AP must also continually monitor for the same radar pulses, and if it detects them while using the channel, it must jump out within 100milliseconds.

Again, generally, these channels are not enabled on retail routers because its extra time and cost to get this certification. You might find it in a "telco" branded AP, but very rarely on a Netgear/Linksys/etc retail router.

On the Client "Station" side, there is generally not a certification for this. HOWEVER, if the device can operate in some sort of "soft AP" mode, then they probably have to disable the channels. Example for this with google tablet would be wi-fi direct mode or Miracast (a video streaming application on top of wifi direct).

It could also be just a cost issue. Cheaper to only enable non-DFS in the radio.

I have tested a bunch of Wifi Client devices. What is see is the 5ghz USB dongles generally dont support these channels, however most laptops (mac or intel 62xx/63xx/5xxx) will all be able to see the DFS channels.

I think the only way to enable the channel on the device is to break into the Wifi driver. This is usually locked down pretty tight because if you can break into it and change it, then google is responsible for you hacking in and violating the CE or FCC certification.

Regarding "how does it detect my region", there is a part of wifi called 802.11d. Read about it in wikipedia.

Basically, the AP (access point radio) embeds the country or region in the beacon, so the client knows where it is based on this beacon. This is so an wifi client device can be manufactured with one firmware, but be shipped anywhere around the world. Based on the AP beacon, it can configure its allowed channels table and tx power per channel.

My 5ghz works on channel 40 but i noticed another issue - incredible battery drain compared to 2.4Ghz. Usually my tablet lasts for about 10 days on a single charge when I leave it lying around the house wirh wifi connected. As soon as I started playing around with 5Ghz, the battery would drop by 50% overnight. Perhaps the n10 was trying harder to communicate but it was only one floor directly below the router, and no one else is on channel 40 in my area.
