Hello people,
This is not the normal complaint thread about WiFi and Bluetooth issues, so please don't flame without reading.
I have managed to reproduce and NOT reproduce the WiFi speed issues when streaming data or audio thru Bluetooth, and I have found a pattern.
I'm almost sure it is a Software issue. With the Prime running WiFi and Bluetooth over the same chip/antenna it is normal to have a speed drop when using both, but not to bring WiFi speed to a crawl (300kbps tops).
So, what I'm asking for is information about the Bluetooth device you are using, if you can give me brand and specific model better, the more information I have about the device the merrier
Second, I need information about your Wifi speed with stream and without stream or at leleast if you have major speed drops or your if Prime works well.
Ill be going this weekend to Saturn or something to try top-notch super expensive Bluetooth devices and see the results.
What is the pattern you found? It might explain why some people bt/wifi works fine and others dont.

Something about the Bluetooth profile being used by the tablet when connecting to devices.
I posted some videos about my prime being able to stream HD video while listening to it through Bluetooth. And some speed tests while using my AKG 830BT headphones.
What was my surprise when using the cheaper Motorola DC800 Bluetooth receiver or headphones? The issue everyone was complaining about here, WiFi speeds of 150K... which of course is useless for anything but chatting.
Doing some research I've found out that those motorola devices use older BT versions (2.0) and one of them does not have HQ A2DP audio.
Long story made short, after testing a few of the BTdevices I own, I found out some of them cause issues while others not.
That's why I'm asking now here, users with and without issues to post their BT Device Models/Brand so I can search which BTprofiles are being used and if some of them are causing issues.

This makes sense though since it most likely is a hardware issue. A2DP is high bandwidth. The identified cause of our woes is the fact that wifi and bluetooth are on a single module. So when A2DP is being used, most of the modules time is used on bluetooth and less on wifi, thus slowing down speeds. The solution from ASUS was using RMAs to add another module so that one is dedicated to wifi and the other to bluetooth.
I could be wrong though.

It would make sense, if it wasn't backwards!
The High Quality A2DP Profile audio is the one NOT killing my WiFi speeds. Every time my Prime connects to an older device using one of the other profiles the WiFi speeds go to hell.
Both WiFi/Bluetooth being in the same Module can cause speed drops, but not completely kill WiFi Speeds.
These are my speeds when using the AKGs Headphones:
No BT stream: 24.91 Mbps.
BT Audio streaming: 18.13 Mbps.
(video and stuff here)
That speed difference IS the one caused by both running on the same chip.
Same tablet, same router, but I change the headphones and the speed wont go past 150kbps. Doesnt matter if the prime is sitting on the router.
Anyways, I'm asking the people who was complaining about the speed (and those whose Primes do work)to feed some info, it is not like I'm gonna waste others time Ill do the research and tests. Just need a bigger data pool.
Go for it. Good luck
Sony DR-BT101 (headset, not an ear piece)
I was told by Asus they have a "fix" with new hardware if I wanted to RMA my device. I just don't know how effective the "fix" is.

How bad is your WiFi loss, partial loss (normal from using WiFi/BT on same chip) or total, like going down to 150K~?
I have never measured as I just don't use the combo anymore. I know it happens, got frustrated, and use my wired ear buds after the first few weeks of owning the tablet. It does have the signal degrade though. The headset is about 2yrs old.
I can test it out when I get home. The work wifi is limited to 750kb download speeds per user.
I have a Netgear WNDR3700V1 with fibre 35/35mbit
Using the Plantronics BT300 headset the wifi drop to under 1 mbit or almost zero, YouTube buffers.
Without BT I have full speed above 30mbit at least.
The only way to "avoid buffering and dropouts" is to use a WN3000 Netgear Extender in same room where the Prime is.
This way I manage to listen to Youtube without drops.
So if the signal is still stron the loss is "not bad", but how many do have 35mbit up and down with fibre.
Those with low speed, will still have drops.
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?

hey all..
I am having some weird problems with Android devices on my company wireless network.
My company makes games for Android and Ios and we test our games a lot on a variety of devices.
For whatever reason, some of our Android devices, which range from older version Samsung Notes, right up to Galaxy S4, have trouble with wireless speeds.
I am starting to believe its Android mostly because other devices have no problems, such as laptops, Iphone 4s and above, Ipads etc.
When I say they have problems, I mean they tend to lose connectivity to the wireless network and then reconnect, or their speeds are just way too low.
Iphones for example tend to get anywhere between 15-25Mbps when I've tested them. My Laptop is able to get 50 (I realize that a laptop is not a fair comparison).. and yet some of the Android devices here, Nexus 7 tablet, Samsung Galaxy Nexus (4.2.1), get around 1-3Mbps.. Also, my personal phone, an LG Optimus G, running Cyanogen Mod, gets 3-5 Mbps on the same networks as the other devices are on.
I don't understand what could be the reason for this huge discrepancy between devices and its very perplexing. At home on my Asus router, my phone gets a constant 20Mbps always.. and that's just a single router. Here in my office we have a 12 Access Point Wireless grid which provides signal to the enter building.
I have tried many different things, from adjusting the networks to only be G type, removing encryption for testing, upgrading phone OS's and making sure they are their current version.. also adjusting the wireless options such as turning wifi off during sleep, turning off the optimize wireless switch, everything I could think of.. and yet on some devices it just crawls and I don't get why.
Has anyone come across this before? I'm racking my brain here trying to get to the bottom of this ..
Thanks for any ideas and suggestions.
How about reducing the DHCP lease time on the router?
On a much much smaller scale, I've managed to deal with some devices having issues on my home wifi by turning on static IP via the device wifi settings for the connection.

Thanks for your reply.
I will try to change lease time on one of the networks and test to see if there is any change.
One of the devices that i'm having the most trouble, I tried to join after setting a static IP and found the same issue.. disconnecting and slow speed.
this is whats so weird.. I also have a Gtab 3 and am getting 30Mbps down and 30 Up.. its blazing fast, same network, different android version.. but not disconnecting and works fine. It just doesn't make sense.
I also had an Iphone 4s user come up to me and he's having the same trouble. It will disconnect frequently, and when we run a speed test its crazy slow. Meanwhile other iphones have no problems..
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)
