Hi,
As a 1.3d user from the beginning. I was annoyed by the wifi behaviour of my folio 100. As time passed, my wifi network was beginning unreachable, not appearing anymore in the list or avaible networks. I was thinking that , as much users, my wifi driver or hardware was the cause. My other devices worked smoothly. Using the folio in my bed (that is new !) I've noticed a lack of coverage by my wifi router. Using the alternative firmware from dd-wrt on my linksys wrt54gl, i've increased the signal from 74 to 140 mdb and switched channel to one tha is not in use around me. Now the reliability of my connection is good on the folio. Meaning that the folio wifi chipset is maybe weak compared to an iphone or a macbook, and needs particular attention homeside.
Off topic, can't wait for that media player dexter teased us. I hope it handles every audio format to watch scene releases on the fly. I was surprised xbmc on iphone 4 could playback it.
Wifi specs for N10 is listed as "WiFi 802.11 b/g/n (MIMO+HT40)". Can anyone confirm that this is indeed dual-band (2.4 & 5GHz), because HT40 mode is well nigh useless in 2.4GHz--the reason being that 40MHz mode would eat up about 2/3 of the entire usable allotted 2.4GHz spectrum, and would be extremely unfriendly to neighboring devices. Most routers don't allow 40MHz mode in 2.4GHz band.
Now that 4.2 supports Miracast, 5GHz support for high throughput is pretty much a necessity. Kindle Fire HD has dual-band, and it's kinda the baseline for tablets. Thus I'm assuming the same for N10, but would like confirmation.
Check this link: https://sites.google.com/site/androidpresssite/home/tech-specs
It says "Dual-band Wi-Fi 802.11 b/g/n (MIMO+HT40)"
I would think this is 2.4 & 5GHz. Samsung has been using dual band in most of their products. So, don't think this would be any different.

But wouldn't you expect a listing of 802.11a then as well?
>But wouldn't you expect a listing of 802.11a then as well?
That was the erstwhile practice, posting abgn spec as an indicator of dual-band capability, hence my question. But .11a has been out of fashion for years now, so phasing it out of the specs list is a good thing. I did check into a few recent wifi adapters with dual-band support, and the 'a' is not present in their specs.
I doubt normal users would notice whether a tablet is dual-band--at least for now. But Miracast capability should push dual-band awareness to the fore, and I expect the next gen of tablets will have dual-band alongside Miracast. The trend is already set for the latest entrants--Surface RT, KFHD, and N4/N10 all have dual-band and MIMO ants. N10 in particular has HT40, which would be useful since it will be outputting 1080p, whereas the others only need to output ~720p.
i think dual-band is a definite necessity in any of today's tablets, I couldn't believe the nexus 7 didn't have one when I originally bought one, then was astonished Asus would drop the ball even on the infinity! A mid-2012 device that retails for $500, without dual-band! Crazy talk I say!
I'm looking forward for the next tablets to get 802.11AC!
speed up your hardware development tablet manufacturers! I know it ain't easy, but they've got a better chance at pushing newer wireless standards than I do!
Not just dual band. New tablets need to have more than one antenna too. The Kindle Fire HD is a good start.

They do, MIMO = multiple input, multiple output, antenna diversity
BTW N10 doesn't have miracast, probably because of memory bandwith, too many pixels to duplicate.

The N10 has amazing memory bandwidth -- 12.8GB/s. Also, the wifi bandwidth is easily enough to transmit 1080p video unless the signal is very poor.

This is outside my range of knowledge, but I ran a few Google searches.
"The Nexus 10 does have enterprise-class wireless networking hardware, with dual-band 802.11n supported alongside MIMO internal antennas (oddly, 5GHz 802 11a has dropped off the specifications — probably because nobody has ever cared very much)."
The Nexus 10 features the latest 5GHz, MIMO Wi-Fi 802.11n. Its wireless performance was considerably faster than the Google Nexus 7, but not as fast as the fourth-generation iPad. On a 5GHz, high-speed corporate network using the Ookla Speedtest.net app, the Nexus 10 averaged an admirable 22.3Mbps down, while the iPad 4 hit 37Mbps down.
Dual-band Wi-Fi 802.11 b/g/n (MIMO+HT40), Bluetooth, Dual-side NFC (Android Beam)
I assume "dual-band" is what you're looking for. One article I read mentioned that it had 5GHz 802.11n. Anyway, the pcmag review -- where they ran the Ookla Speedtest.net app -- sounds like an intelligent, reliable source. I hope that's the info you're looking for.

I believe the specs were a 64-bit dual channel memory interface w
Yes it does have high memory bandwidth for a tablet or phone, but that memory bandwidth is actually just the theoretical max and furthermore is completely used up by the devices screen resolution. It may be high compared to what past devices have had, but it is still not enough for what the device should have. I believe the specs were a 64-bit dual channel memory interface with low power DDR3-800 speed memory chips. Samsung really should have gone with their incredibly cheap and high density 1333 chips since it probably wouldnt have even cost anything more.
This lack of memory bandwidth was my reason for making a thread a couple days ago on the possibility of adding RAM overclocking to kernel tunables, and possibly even RAM timing adjustments. The largest thing holding back gaming and benchmark performance will be the memory bandwidth, second worst thing will be the GPU speed
As for wifi, Ill know for sure when my device gets here in a day or two but I would suspect it will have both 2.4 and 5GHz bands. No sense having MIMO and HT40 if it doesnt even support 5GHz

That's twice the bandwidth of the fastest Tegra 3 devices. I was just looking at the GL offscreen benches, too, and the GPU seems quite capable. The hardware is there; if there are performance problems, they must be firmware or software issues -- and correctable.

Does anyone know if the Nexus 10 will benefit from a 802.11AC router, like for example the Linksys AC1750 or NetGear R6300? Is getting a 802.11 AC router worthwhile?

Not yet they are not worth it. If you do some research on AC it will double in speed and bandwidth in the next gen of AC devices. Besides it will take some time for devices to gain native AC support. Think back to when N (draft) came out and only the last year or so has really maxed the potential of N capabillities. Id wait. Just my 2 cents.
>Does anyone know if the Nexus 10 will benefit from a 802.11AC router, like for example the Linksys AC1750 or NetGear R6300? Is getting a 802.11 AC router worthwhile?
802.11ac requires hardware on both ends to potentially realize the higher speed. And even when the equipment has the label, it doesn't mean that it has the additional hardware (radios & antennas) needed to attain higher bandwidth. Nexus 10 doesn't have, nor can it be upgraded to .11ac.
Moreover, 802.11ac is not finalized, and all AC equipment are draft-based. That means brand-interoperability is low, and it's best to buy both router & adapter from the same vendor.
These said, a new 802.11ac router may confer benefits if its N portion performs better than your present router.
Suggest reading reviews of current draft-AC routers for better grasp of the pros and cons. Here's a typical review from a respected site:

Thank you very much for that reply. Just to be clear so I understand this properly; the Nexus 10 does not have a 802.11AC chipset? I'm better off getting a 802.11N router that is able to do 450x450?
I don't know about speeds, but my N10 connects to my 5ghz network and performs better there (i.e. no YouTube buffering problem) whilst performing worse on the 2.4ghz (a few disconnects here and there)
If you have a decent proximity to your router you will almost be better served using the 5ghz instead of 2.4ghz because of saturation. In my neighborhood I've had to turn my router power up considerably just get a foothold on my living area with my 2.4ghz devices. I use 5ghz instead with my n10 and the performance is awesome. If it only had less screen issues! Mechanically it is amazing.
Sent from my Nexus 4 using xda premium
My N10 has a 5ghz 40mhz band all to itself at the office, which leads to some rather nice transfer rates when I'm grabbing 720p tv show rips from the NAS.
It's the fastest device on wifi in general I've owned. Very pleased with it.
one more question:
my router does not support 5ghz, but it does support 2.4ghz and 40Mhz mode.
Will the N10 support that, too?

Good question: or better, what is the max connection rate on each band?
Does it have 2 or three antennas and support 40MHz mode on both?
Wil check tonight with my ASUS N66U (2*450) and let you know.
Cheers
From the updated Anandtech N4 review:
http://www.anandtech.com/show/6440/google-nexus-4-review/4
"...at present there really aren’t any Miracast standardized receivers. I tried a Netgear model which was pre-certification but couldn’t get the Nexus 4 to attach, although I’m told Netgear will update the NTV300SL to support Miracast by mid-December. I’d expect that the rest of their lineup will be ready around then.
"Until we have Miracast sinks everywhere there’s really no way for me to test how this works on the Nexus 4. The Nexus 10 doesn’t include Miracast support, I’m guessing because of memory bandwidth reasons possibly involved in scaling and encoding 2560x1600."
As far as I know, only Netgear PTV3000 is pre-certified. Has anyone tried with that?

Correct
No Miracast in N7 3G (or plain N7) either:
http://arstechnica.com/gadgets/2012/11/googles-nexus-7-gets-a-fresh-coat-of-paint-for-the-holidays/
"Android 4.2 on the Nexus 7 has no major surprises: all of the features we mentioned in our review are here, with the exception of Miracast (which is only supported on the Nexus 4 for the time being) and the new camera features (which are present if you install a third-party camera launcher for the front-facing camera). Multiuser support and lock screen widgets, two features that weren't ready in time for our main review, are also here, but we'll be examining them more closely in a separate article."
Miracast will be available after the update. Which happen last night. Now all you need is a receiver to do the handshaking. The netgear one would do and after it is on you wireless network you would just stream to it like you would a windows media extender. By 2013, so early next year tvs once they start calling them smart tvs :cyclops: will have this feature built into it. Here we come google tv. wouldnt that be sweet to have a nexus 60 inch tv?? or bigger.
n4, n7, n10, ntv, n60 maybe?? i see it happening.
Just to be clear to any readers out there, whether or not there will be Miracast support for the Nexus 10 is unknown and anyone stating otherwise is speculating. What is known is that there will be Miracast for the Nexus 4, but no official reports from google have come out for the Nexus 10.
The hardware support for wireless display looks to be there
http://forum.xda-developers.com/showpost.php?p=34038283&postcount=19
Copied from Exynos 5250 thread -
"Came across this while researching Exynos 5250. Looks like the hardware is very capable to handle the WQXGA resolution with memory bandwidth and power to spare. This white paper also mentions the support for 1080p 60fps wireless display. So I hope Miracast will be reality as well, just Google needs to step up and utilize the hardware to its full potential. Its an interesting read none the less..

Here's another piece of evidence to support that it's coming to the Nexus 10 (found this from another forum). On Google's Nexus 10 Support page it mentions Miracast. Scroll down to the Wifi-Direct section:

I phoned Google Tech Support this morning and asked if the Nexus 10 would have Miracast functionality "out of the box".
Tech guy couldn't answer for sure and promised to respond back to me later via email.
5 hours later, amazingly (to me anyway), I received an email back from him stating that he got clarification on this question and that, yes, Miracast is good to go "out of the box" on the Nexus 10.
I still won't believe it until someone with a unit confirms it.
Miracast is basically just a superset of WiFi Direct, doesn't require any additional hardware on the broadcast device...if it can use WiFi Direct, it can do Miracast with the proper software.
So I'm not worried about it being on the N10, if the software isn't there just yet, it will come.
http://en.wikipedia.org/wiki/Miracast
Yeah, I had called them and asked them too. He had no idea what Miracast was and so I explained it to him. He said he'll have to ask his supervisors and put me on hold. He came back and said "Yeah, you can stream and watch movies on your tv from your tablet and stuff." I said, "Yeah, but specifically Miracast...Does the Nexus 10 support Miracast?" He then said that's more of a hardware question and I'd need to call Asus. Asus huh? Interesting. Are they taking Samsung support calls now. I just ended it there knowing I wasn't going to get anywhere.

My understanding is that while the capability might be there if Wifi-Direct is there, it still doesn't mean that it will be Miracast certified and thus might not be supported by Android.

FWIW, I have a Galaxy Nexus running Jelly Bean 4.1.1, which supports Wi-Fi Direct. I also have a Netgear PTV3000 WiDi/Miracast capable adapter. My phone sees the adapter, but there is no mirroring to a display.

No, just sharing that a WiDi/Miracast capable adapter recognized a Wi-Fi Direct device, a substantiation of Croak's earlier post.
I'm now of the belief that the reason we haven't heard something official from Google is because the Nexus 10 has been submitted for Miracast Certification but is still under review. Makes complete sense. They can't say it supports Miracast until it passes Miracast Certification. They don't want to say it doesn't because they think they'll ultimately get the certification. So for now they just stay silent. Whereas the Nexus 4 has already completed Miracast Certification so that one they could officially announce. Perhaps the same reason they've been silent on the Nexus 7, which being that it has a Tegra 3 in it and Nvidia says Tegra 3's have built in support for Miracast and are working towards certification, should mean that theoretically it is capable.

That actually makes a ton of sense. I also read somewhere that Netgear is working on updating the software on its PushTV3000 to support the Nexus devices that have Wifi Direct/Miracast. They hope to have that done by next week, apparently.
I recently purchased a M8S PRO as my android tv box. I upgrade [purchased it] specifically because it supports 5ghz and i thought the wifi would perform better.
However whether Im streaming with the browser or even playing movies off my nas i have latency issues
I believe this is due to the internal wifi chip because i also have a nvidia shield tablet which has none of these issues even if i put it in the same location as the M8S PRO
Should I buy a range extender or a new wifi dongle for it (like this one)?
Does Android support more then one wifi adapter? Will i be able to disable the internal one?
Or should i try a custom rom (i dont see how this will help but maybe im wrong about it being a hardware issue)?
Try various configuration in your router, you can try 20 or 40 mhz bandwidth, maybe disable legacy modes and use AC only, I had issues before with 5Ghz when legacy modes were enabled like A B or G. let me know, as I just purchased this box and im still waiting for it. , also you can check the 2.4GHz band.
regards.
screw these dam things
as far as i can tell the wifi chip in this thing sucks
i put the dam thing right next to the router and its still horrible
topping out at 400-500 kb/s on lan transfers over a minimum presence 5ghz wifi
sorry for late reponse, i was loading lede onto my router and trying other things to fix the issues i have with this device playing items across the lan (via samba)
Hey there!
Ever since the official Android 10 update I'm experiencing interrupts in my wifi connection whenever I put my tablet away for a few minutes. I'd guess that's probably some new feature for battery saving, at least it's called "sleep mode" on my OnePlus 5T, but I haven't found anything similar on my tablet yet. The patch notes for the Android 10 update also don't mention anything wifi or battery related as far as I can tell....
It's not my wifi since my phone and my bf's phone all work as usual.
Any ideas or anyone experiencing the same issue? Already checked dev options in the settings, but couldn't see anything related. Maybe I missed some settings somewhere?

Yup! I did a couple of things though, so I don't really know which of them actually helped fixing the issue, or if it's even required to do all.
- I got 2.4 GHz and 5 GHz wifi. They shared the same name, which made my tab switch between them often. I renamed both wifis so they don't share the exact same name (fun fact, they're now called Pizza 2.4 and Pizza 5). My tab is now only using the 5 GHz one, the 2.4 one now is only for devices that don't support 5 GHz (like my New Nintendo 3DS XL or my printer), because I live in an area where many people are, and the more wifi channels are occupied, the messier (and more prone to interferences) it gets. 5 GHz has a smaller range but is also stronger, which is perfect for my small flat. On 2.4 there's way more interferences because it has more range.
- In my router's settings, I've set the tablet's IP to static, because I've read somewhere that this might help.
Can't tell if both steps are required, you might just wanna try out one first if you don't necessarily want a static intern IP for example.
My tablet also used to take ages to find my wifi, which is now fixed for some reason. On my OnePlus 5T it still takes very long to find my 5 GHz wifi, although it also has a static IP. But both devices won't disconnect randomly anymore.
