Long-time troller, first-time poster.
I'm a network engineer, so I know a thing or two about WiFi and what not but this has got me scratching my head.
For the life of me I can't get my Nook tablet to connect a speeds greater than 54Mbps via WiFi. I've got my Galaxy tab next to the thing and it's connecting at 65Mbps.
It's not an issue of frequency I actually disabled 5GHz spectrum on my AP to check. The AP is a Cisco 1142 dual radio 802.11a/b/g/n WAP. But I've also tried with a Cisco/Linksys e1000, and a netgear what-cha-call-it at a friend's house. No dice on WiFi speeds above 54Mbps
Even my Xperia play connects at 802.11n 2.4GHz speeds.
I'm running 1.4.0 Rooted if that helps. Plenty of reboots to kill a cow if anyone thinks that's the problem.
I'm thinking that B&N have the nook locked to 802.11g speeds.
What do you all think?
Something is up with the wifi for sure. If you google nook tablet wifi problems, you get a ton of hits. I could get my nook tablet to connect to my router but could not get the internet to work on the tablet. After rebooting the router and the nook several times, changing several router settings and doing everything under the son, I finally changed my security from the N to the G only setting ( Dont really remember which is was) and this fixed it. Keep in mind my android phone, my wifes blackberry, my playstation 3, my friends mac book and my in laws ipad have had 0 problems connecting to my router. I think its safe to say its the nook tablet.
Yeah I've seen the issues with the WiFi on Google and even here on XDA, but everybody seems to be having issues with not connecting, or connections get muddled up and they have to reboot their nook.
I'm still thinking Barnes & Nobel deliberately throttled the WiFi to support only 54Mbps max. Although I have no clue as to why they would do that.
yea i think they capped all the hardware cuz even the sound is low but when rooting and using a android media player its way louder
Hmm... I wonder where items like connection speed, and volume would have their parameters kept. I wonder if with Root one could edit them?

Tweaks can be done i think.
Where to look? : system/build.prop and system/etc/
In light of all the recent wifi issues with the Asus Transformer Prime. I got thinking.. Would it be possible for the prime to theoretically use a USB wifi dongle as the receiver through the keyboard dock?
Obviously android since gingerbread has had USB hosting and the ability to use mice, keyboards, game controllers and other devices, but how about a USB wireless networking adapter?
Thoughts?
Interesting thought and I have no idea... For average use wifi suffices but might be a nice option when going to a place where wifi is crap (like vacation house or something).
Iwas thinking the samething. The question is would there be driver issues with the USB device?
Not quite yet
If you are simply talking about a Wireless N Wifi dongle, there would be little gain, While not the best, a properly functioning Prime gets reasonable WiFi performance. Witness mine, which I regularly see 15-20 Mbit downloads speeds, so not great, but certainly acceptable.
If insetad you want a 3G wireless stick, at the present this is not an option. Honeycomb and even ICS do not provide support for these natively, though a rooted device I believe can be made to work with 1 or 2 3G sticks. When talking 3G, the best move is just root your phone and tether to that, but watch to 300 Mb game downloads folks. AT&T will make your head spin with the $ if you go over the measly 2 Gb plan (I was grandfathered in on an "Unlimited' data plan, and lost it... no biggie, they still bust you if you repeatedly use high bandwidth.
Good evening
I was wondering if there is any other thoughts on using a USB WiFi dongle with the prime. The reason I ask is that I note several retailers are starting to get stock in the UK and I am on the verge of purchasing.
The only issue I have is the WiFi range issue as I work on an offshore oil rig which has a WiFi network and I can currently use this within my cabin on a night with my net book to surf the net. However as there are a fair few partitions and a good distance etc between the WiFi router and the cabins, I don't think the Primes WiFi range would be sufficient (based on others posting issues when they are trying to pass through a few walls).
If a USB WiFi dongle could be made to work i would buy a prime tomorrow, otherwise I think I am going to stick with the net book for a while longer and wait for another model / manufacturer with Tegra 3 (I really don't want to follow the crowd and get an Apple!)
Many thanks!
Chris
Should knlw what that could be a good idea. THERES a guy in developement thread named Saturnde. He has made a thread called new or added drivers or something. He compiled a list of new drivers into a zip file for support of new USB devices that aren't normally supported by prime. He said if you want drivers for a particular device tl let him know. He will need name of device n model number or something. Won't hurt to run it past him and see if its feasible or possible. Let us know how it goes.

Can you syggest a wifi dongle that i can use in an android tablet (my tablet's wifi is "broken")
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.

WHAT!? I thought it had miracast?! Or is it just that Android 4.2 supports it? I'm totally confused now..

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.

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?

I've been experiencing problems with WiFi direct screen share connections too, like Miracast protocol

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.
