hi,
here is a question for gen8 developers :
I read this answer on wifi n from Archosfans :
Archos Support wrote:
When connecting to a wireless network there is a certain connection speed
attained. The better quality signal network the higher the connection speed
possible. B < G < N when it comes to wireless network signal connection speeds.
54mbps was the max speed possible with a G-Network for wireless. N goes a lot
higher than this. Our unit is capable of connecting to an N-Network however we do
not allow a connection speed higher than 54mbps to conserve battery life. Thus if
your N-Network is broadcasting higher than that and will not allow a connection
speed of that low you won't connect
Is there any chance to get a real Wifi n by modifying the firmware?
thank you.

To the developement thing i can't say anything,
But 54 mbit is 6.75 mb per minute ;-)
this is very fast!
I use dsl 32.000 on my a101 and it worked for me.
Thank you for your answer.
I get about a real 2 Mb/s with a 54 Mbps speed with an Archos 70 it. With my laptop, I get 6 Mb/s ( around 150 Mbps). That's a huge difference !

Oh you've fast internet
Mhm i think we could change the wi-fi binarie so we can support faster internet
Buti can't do that.
Idont have experience with that..
Wow seems some people are actually getting response from archos-support i've read in one of the archosfans threads that the chipset does not support the full N speed..however with this comment of achos...
The problem with all the information on the internet is to get the right information in the right order and draw the right conclusions.
1. The chipset in the Archos is able to connect to a Wifi-N only AP
2. It has a maximum Connectionspeed of 65MBit/s
3. Archos decided to lower the maximum speed to 54MBit/s for energieoptimization
4. Because of this it doesn't connect to a AP that wants a minimum of 65MBit/s
So once and for all, Archos can connect to Wifi-N.
The hardware would be able to do 65MBit/s
Even then to get more then 2MByte/s is not likely to happen as all downloads are going to the ssd/sd and this two together ( wifi + "hd" access ) with this processor and the sorounding components wont be faster.

a quick question. after installing battery status. i notice it also shows the cpu status. currently i am running PK's excellent PK1 rom. the information i get is:
cpu = 312 mhz
battery = between 190mA to 700mA depending on what i turn on.
is this normal??
i thought we are running a 624 mhz rite? so why is it 312 mhz (or half of what the cpu speed)?
thanks for your help!!
It's a known bug in batterystatus, check their website and it's mentioned in the faq.
LOL 312 * 2 = 624 Mhz !!!
it's a dual Core CPU ????

Battery status has a maximum of showing the CPU speed and thats at 312 MHz and when u install it on devices greater then 312 MHz then it will show just 312 MHz !!!! it sfault of the software u are using !!!
ha.i c. thanks for the update. for a moment.. i was raking my mind what happend to the other 312 mhz too.
another comment.. what is the so called "normal" battery consumption? as mentioned, i am running PK's excellent PK1 rom, bluetooth 100% of the time. i use it like a phone.. a little bit of notes writing.. i am getting between 200 - 500 mA. is that normal?

"Normal" is a broad term here. It depends most on the brightness of the LCD and what hw modules you have switched on and used. It also depends on the radio ROM, some of them increase power usage quite dramatically, there are fixes available in PK2 thread if you suspect it's affecting you, although I don't think so at 200mA.
Normal for ME - ie 80% brightness, GPS on, GPRS on, GSM on, GPS software running and reading maps from HD I would expect something floating around 750-1100mA.
With max brightness the Ameo will discharge even when connected to a weak USB power, like some low-amperage car adapters. It did happen to me once.
When you say you have usage of around 200-500mA it means it's rather low, probably most modules inactive (GPS, WiFi, 3G, BT etc.) and brightness in a decent range.
Unfortunately our Athena is rather energy-hungry in real life use. I have to charge her nightly and even sometimes I'm forced to charge from car/laptop when having longer support sessions on RDP+WiFi/3G.
Then again it's just physics and arithmetics, you can't expect such a monster of a screen to run on 1mA. Not as long as you want it lit.

no actually it's a fault as above person said , ip posted this question in thier thread on this board and got a reply look around their thread as i can't recall the post number at moment.
but I know that it reports 100% correct on my HTC Hermes ( Vario II ) and my HTC Universal ( Mda Pro ) as well as even my really old HTC BlueAngel ( M2000 )
so it's more likely just not supporting the newer chip

Hi
After updating to FW 2.1.02 I hoped to get a n-wireless speed connection with my router (other devices connect in n speed without problem) as the changelog of the fw 2.1.02 says that n-wireless is now enabled.
But I still have a 54 Mbit speed mentionned in the connection details.
I have a dualband router. Both freqs are configured to have 300 Mbit.
The A70 doesn't see the 5 MHz network (because I think it has a 2.4 GHz chip inside).
Other devices connect to my router with n-speed on the 2.4 GHz net.
How about you? Any success after fw upgrade or still 54 Mbit connection?
Any solution for that "problem"?
(I want n-connection, when the A70 says it has a n-chip inside...)
I have the same issue !!!! i'm using a sagem fast 3304 >>300mbps
Archos when will we have wifi-N SUPPORT !!!!! And Flash support ....... ¿
Not working for me either with wireless n.
I'm only seeing 54mbit so far.
Same here.
This is the answer from a member of the R&D team of Archos:

wifi chipset supports single stream thus caps at 65MBps raw PHY rate. It has also all aggregation features of the IEEE802.11n standards that enable to save the silent periods over the air and increase throughput efficiency.

And thats exactly what my wireless router shows me as connection speed for the archos: 65 mb/s. So it's definitely a n-connection but limited to 65 MB. So there will probably never be a faster speed with that device, as the Archos guy points out that it's a hardware limtation of the chip .
One more proof that it's an error to always see 811n as synonymous to 300 MB/s.

not the fastest disk speed in the world :-/
Btw, this bad performance is the source of 90% of all "hangs" on the Prime :-( The CPU is nice and fast, but the disk sucks.

My USB stick is faster on my Laptop (but not on the ATP)
I ran some bench on mine, Stock ICS, and here's the result
With side by side comparaisons, that's how awefull the storage is....
That's pretty bad. How does this effect the usage of the tab? Is it noticeable?
Sent from my DROID2 using xda premium
It's hard to know what's causing it but there is definitely a lot of freezes in the otherwise butters smooth animations. If I'm downloading torrent in the background, the device become unusable and applications (mainly the launcher) stop responding.
Every media take much to long to load,
I also suspect big movie files to suffer from that.
Transferring files on and from a computer is a pain and often the tablet simply stop responding.
In my opinion the storage speed is the bottleneck of the Prime performance wise. It s like using a computer with a slow ass HDD versus a one with a super fast SSD.
Of course i wish someone could re-run the bench on their tablet to confirm this.

I wonder if it's just that the internal SD card is slow, or if it's poorly optimized in software? I guess we'll find out once the bootloader tool is released.
My fingers are crossed for poor software optimization!
That write speed is just too low, I'll try the benchmark on my TP tonight.
When custom roms/mods etc. arrive we will have the chance to test it under ext4,JFS and other filesystems so i believe we'll see better performance
I remember seeing early reviews on the TF201 that the internal memory is unusually slow.
Why would Asus put such a high build quality on everything but the storage speed?
I have a feeling this is not hardware related but rather software related. There is no logical explanation why the flash memory inside our devices is so much slower than the common average.
What I want to know is how much bandwidth is available for the internal storage?
For example: I purchase a 64GB SSD drive that is meant for internal 2.5" storage drives. I hook it up externally and plug it into a powered ESATA port. The max read/write speeds of the SSD are around 300mb/s but the port's max read/write speeds are only around 200mb/s.
Did Asus make some unnecessary sacrifices to make the price of the Prime reasonable? I really hope not.
On a different note:
Copying files from Windows 7 to the Prime is immensely slow.
On Mac OS X 10.7.2 (Hackintosh) copying the same file is MUCH faster.
Using AndroBench -
Seq Read 19.59 MB/s
Seq Write 4.01 MB/s
Random Read - 2.71 MB/s
Random Write - 0.25 MB/s
SQLite Insert - 14.17 TPS
SQLite Update - 16.68 TPS
SQLite Delete - 17.79 TPS
Really bad in the ranking compared to the other devices.

Well, I wanted to test Bonnie++ also on a USB stick on the ATP, but somehow it took insanely long, so I canceled that. I also suspect it to be a S/W problem, which gives hope for it to be fixed in an update.
I've not got my Prime with me to perform the tests, but having seen the results posted in here, I have to say that my SGS2 absolutely *smokes* the Prime in terms of I/O throughput. Very disappointing, I think that this thread needs to be brought to the attention of Asus.

I get the feeling they knew about this before launch.
Are there any hacks, settings, or drivers that can be adjusted in either the os, or bt stack, or wifi drivers to help reduce the repeating key/mouse stutter that seems to be common in KitKat when on wifi simultaneously? Keyboard pro is a help but it is still very hard to use the bt peripherals effectively whilenthey are jumping all around the screen......
I have heard this is only an issue on 2.4 GHz networks, is that true?
The wifi and Bluetooth are on the same chip. They don't like to run at the same time! It's a hardware issue, not software that no manufacturer seems to care about. Every Android device I have used has issues when using both at the same time. For example, Bluetooth headphones for watching youtube videos means the wifi cuts out every few minutes. A possible solution would be a cheap usb Bluetooth dongle via USB otg.
Use 5 GHz Wifi, then the problem should be solved.

My gateway router only offers 2.4ghz. Do most home network devices, ie: Tv, blueray, printers, all support 5 GHz or is that only on new or special devices?
A router which has 5 Ghz WiFi always also has 2.4 Ghz because indeed only some devices support 5 Ghz, so a router with only 5 Ghz would be very limited in usage.
Hi there
I'm trying to achieve the best bandwidth over wifi which i need for local file transfer, but strangely enough my Redmi note 4x (Mido) can't get any higher than 150 Mbps link speed over wifi.
My router Asus rt-ac3100 can handle way more than that.
Looking at SD625 specs reveal that the SOC can peak up to 364Mbps.
I used a bunch of 7.1 and 8.1 ROMs but they all have the same results
So i'm wondering what is the limiting factor, and if there is anything to bypass it
The phone's WiFi chipset only supports N bands. It's a/b/g/n only. Though you'd think it'd connect a bit higher, since N allows for 600Mbps. My laptop is stuck with an Intel a/b/g/n card and I get a link speed of 240 to 270Mbps when connected via 5 Ghz.
How far away is your router? My router is in my room, where I am right now with all my devices. Though the link speed on my Note 4 is still capped to 150Mbps. Strange. Don't know if it's a fixed hardware limit or something else. I previously checked on MIUI and now on LOS 15.1. Both show the same 150Mbps link speed.
My LeEco x722 (SD820, 802.11ac WiFi) got 866Mbps easily. I also had another Snapdragon 625 phone, but with AC WiFi. It too got a pretty high link speed of around 600Mbps. I think the issue is that the wireless chipset in the Note 4 is very poor.

The router is in the same room as i am with no obstacles between.
I found (at gsmarena.com) that Mido only support up to wifi N (no AC) even though the SoC support AC standard, probably due to the implantation of cheap radio hardware, and because most phones optimized for efficiency it run only on a single radio band that is why 150Mbit and not the 300/600mb advertised even for wifi N standard.
The news left me disappointed, for a top midrange phone not to support AC, i guess something to consider in my next phone
The twin brother of mido the Mi A1 which is literally a Redmi note 4x play edition support AC wifi. Moreover the Mediatec version (nickel) also support AC wifi, so why xiaomi left the redmi note 4x without?
The more i dive the more i feel betrayal.

I believe it is a driver from the firmware and/or kernel that doesn't allow full speed N or AC to work. I have looked into most of the software and cannot find what is stopping it.
Try wired connection by buying usb adapter maybe? Have you tried flashing latest dev firmware along with rom that might help.

Wired connection is not an option for a phone. I tried both stable and dev firmware with a bunch of roms and it is always the same 150 Mbit link.
Gsmarena listed the phone as Wi-Fi 802.11 a/b/g/n enabled device. So it it official, no AC for mido
