Wifi channels - Asus Eee Pad Transformer Prime

I am using wifi analyzer and it shows some channels are better than others. How does one change to those channels in ICS?

You don't "change the channel in ICS". You change the channel your wireless access point or wireless router is transmitting on.

You don't change the channels on the client. This is a setting on your access point. While 2.4GHz has channels 1-11, only 3 are truly usable without causing interference to everyone and everything else. These are channels 1, 6, and 11. This is due to the frequency separation and overlap of channels. When you use channel 6 for example, it bleeds over into 4,5 and 7,8.

Understood! Thanks for the replies.

[Q] Anyone have Bluetooth and Wifi working?

Does anyone have a prime that you have Bluetooth turned on and streaming, and you have wifi on and streaming (say Netflix and external speakers) and it works?
I just want to know if SOME primes have Bluetooth and wifi working at the same time.
I have a Prime with working bluetooth and wifi when on together. Last night I paired my Prime to my phone via bluetooth and transfered about 130megs of stuff over to the Prime (the only thing I have with bluetooth). While doing that I was watching a whole bunch of clips on Youtube with no problems - a mix of HD and non-HD videos.
Speedtest when both BT and Wifi on does not show a huge problem for me.
The only issue I have right now is a non-working GPS.
Humm, I just think that most people have not tried and it's a bigger issue. Mine is useless if bluetooth is on the wifi stops dead.
Mine works fine as well. Here is the link to my OP with video of Wifi/BT streaming.

I have this same exact issue. Wifi is fine, even with BT on but GPS is a no pogo go.
If I connect to a BT gps device, turn on the Bluetooth gps program after pairing, my wifi goes straight downhill and almost completely stops, even though wifi signal strength is strong.
I haven't tried other Bluetooth devices.
Mine is also working

I can stream Bt Audio to headphones while playing a file via wifi on a windows share well. However the audio is not in sync, but for me the sync if off even if I turn off the wireless radio.
Mine works together but wifi slows down drastically until I turn off the Bluetooth device.

Bluetooth & wifi

While Streaming mp3 to my big Jambox, My speedtest.net app shows speeds of 100kbs Down from 10mbs? My transformer prime has the same problem...
So no netfilx and bluetooth at the same time...

use transformer prime as a hotspot for laptop/ps3

to stream videos from windows 7 to my ps3?
not using the internet just using the prime's hotspot feature
Why do you want to use the tfp as hotspot instead of just setting up an ad-hoc connection on your windows 7 machine and connect your ps3 directly to it!
I don't understand why someone would want to use the prime as a hotspot. it as no cellular data and any device you would point to your prime could obviously hook up to what ever wireless ap your prime would have. am i missing something here?

? again, I want to stream media from my laptop on to my ps3. I notice the prime has a hotspot feature so me not being tech swavy I figured I connect the laptop to the prime and the ps3 to the prime to share media
Like I said you don't need the prime your laptop has a hotspot feature as well. Just go to the network center add a connection create an ad-hoc connection give it a name and password done. Now connect your ps3 to the network and start streaming.

[Q] [SGP311] problem with wifi and bluetooth working at the same time

Does anyone have the same issue where the wifi becomes wonky when the bluetooth is on and connected to a bluetooth keyboard.
I have the Sony Xperia Tablet Z wifi version with an Apple bluetooth Keyboard.

no fixes or anything yet? second for that link please. this is really annoying. just got my keyboard and i guess it's useless?
I have a tab z and the z handset which has been upgraded to 4.2.2 stock. Both have this issue

I am having the same issue using either a Bluetooth keyboard, mouse or sixaxis controller un my Tablet Z Wifi.
If someone is using a bluetooth keyboard/mouse without wifi problems, could they post here as well. I would like to know If every one has this issue.
This thread is about the same problem: http://forum.xda-developers.com/showthread.php?t=2346553 could the be merged?
I'm listening to internet radio over bluetooth (instead of the inbuilt speakers), have a Microsoft Wedge Bluetooth keyboard connected and am writing this at the same time.
2 Bluetooth devices at the same time plus Wifi, all working.
(Wifi channel is 9. SGP311.)

@hasenbein1966 Could you do a internet Speedtest with and without bluetooth connected, what firmware are you running, and how many wifi networks are on your channel?
My Internet is fast (30000kbps download) I am geting that speed on my tablet z. As soon as I connect my bluetooth keyboard (acctully it is the Microsoft Wedge as well) it drops to ~300kbps. So something happens to my wlan on the Tablet Z. As I am living in a Flat I do not have a channel for my self. I am sharing that channel with 2 other Wifi Networks.
If someone knows what to change on the Tablet Z please tell my, I bougth it just for working with keyboard/mouse!
Mine is SGP312 (32GB, Wifi only), firmware is 10.1.C.0.370, device is rooted, bootloader is locked

just tried playing around with my channels...
the good news is i think i may have actually upped my speeds by changing to a different channel!
the bad news is i drop from around 3.5MB/sec with just wifi on, to under 0.03MB/sec with Bluetooth turned on and a bluetooth keyboard connected... and then it didn't even finish the speed test, it just stopped and said there was a connection error.
this is awful.
Did someone already test whether changing the WiFi to a 5 GHz channel (Bluetooth works in the 2.4 GHz band where also normally the WiFi operates) helps?
(Can't test it myself because my router doesn't support 5 GHz.)
Hi All,
This seems to be pretty common (saw someone complaining in the Transformer forums). I've noticed the same issue myself. I'm using wireless BT headphones, and the Wifi throughput drops precipitously when I'm streaming music to them. I've got a dual-band router, so I'll set up the tablet to connect to 5Ghz and let y'all know what happens.
Thanks,
John Francis
I have now measured speeds with a speedtest app.
When I only have connected my Harman Kardon Bluetooth audio receiver, the WiFi works perfectly normal and has same throughput as without Bluetooth on.
When I connect my BT keyboard, Wifi speed becomes very low (below 1 Mbit).
So, not BT in general is the culprit - it depends on the kind of device!
OK, with the tablet on 5GHz I get ~55 Mbps. On 2.4 GHz, ~21Mbps. These are Harman Kardon BT headphones.

John Francis

@jfrancis999 these rates look both ok. There shoul be no problems. Are these with audio streaming to the Headphones? If you have a Bluetooth keyboard, mouse or gamepad (playstation 3 controller) could you maybe test with one of these connected an 5GHz?
@all if we make a list of all working and not working devices we can maybe find what they have in common an what is the problem.
Not Woking:
Microsoft Wedge Mobile Keyboard, BT Profile HID, BT Version and Class unkown
Playstation 3 dualshock3 controller, BT Profile HID, BT Version and Class unkown
Whit these devices connected Wifi speed drops to under 1Mbit/s
Does any one have a BT Keyboard and while it is connected to the tablet z Wifi speed does not drop under 1Mbit/s?
@someone having good understanding of android and bluetooth: is there a way, I can force the tablet to reduce trassmitting power to class 2 or 3? I want to test if that makes any difference but I do not know how.
It's really strange, since a simple keyboard should need much less bandwidth than transmitting audio over BT, so one would expect the Wifi drop with the audio device, not with the keyboard...
I just have a Motorola Keyboard & Mouse combo pack... I'm not seeing any model number on it, but it's definitely Motorola. Totally kills wifi speed when either one or both are connected. So you can add that to the list.
Hi All,
With the tablet connected to 5GHz I get the following speeds:
* Playstation 3 controller disconnected: 58Mbps down/30Mbps up
* Playstation 3 controller connected: 42Mbps down/12Mbps up
With the tablet connected to 2.4GHz I get the following speeds:
* Playstation 3 controller disconnected: 4Mbps down/30Mbps up (not sure what's up with the download speed)
* Playstation 3 controller connected: 103Kbps down/52Kbps up (OUCH!)
Regards,
John Francis
@jfrancis999 Thanks for your tests!
I will be in my office on Monday. There I will try a 5GHz wifi as well. If that works well, we have at least a workaround. Still, I hope there is a fix for this problem, but untill then we could bypass that problem.
I will post the results here on monday.
I am still looking for someone who can tell me, how to reduce the transmission power of bluetooth on android!?
after a week, sony support finally wrote me back. they said it sounds like a software problem and i should use the PC Companion software to do a software repair. anyone else tried this yet? also if i do this, is there any way to backup EVERYTHING, including my widget setup, icon placement, folders, settings... all of it...
Bah, they simply have no clue.
Like the dudes on the official Sony support forum, this support guy just gave some random halfway "fitting sounding" answer, like a Windows support guy who says: "Restart Windows"...
I wouldn`t use this "PC Companion" crap, honestly.

[Q] Is 40MHz bandwidth supported with 2.4GHz Wifi n on GT-i9300

Hi all,
I've found this old thread about 150Mbps on GS3 http://forum.xda-developers.com/showthread.php?t=1815929
So I confirm that I'm able to connect at 150mbps with my GT-i9300 (international version) by using a wifi n router at 5Ghz.
To be able to reach 150Mbps, I must enable 40MHz bandwidth. It is what is expected because the GS3 supports only one antenna stream (no MIMO support).
With this link, I can download files from my NAS at 5-6MB/s (Mega Bytes per second) that is satisfying me.
The only issue is that due to 5GHz, wifi connection is limited to a small area (it doesn't work well through walls).
Because there is no other wifi spot in channels 1 to 9 (only other spots far enough and both 20MHz in channel 11), I've enables the 40MHz in 2.4GHz carrier on my router. Using my (old) nettop, I've enabled 40MHz support on the only 2.4GHz carrier supported, and I cansee connection link at 150Mbps (my old nettop have one stream too). I've also checked on another fix PC that supports MIMO (2 antennas) and 2.4GHz only that I can reach 300Mbps with 40MHz bandwidth. So I confirm that both are supporting 40MHz bandwidth with 2.4GHz carrier.
So, now my question is:
- why I can not enable 40MHz support at 2.4GHz on my Galaxy S3 ?
Is there a hardware limitation on bandwidth configuration on the RF chip (not the baseband, but RF where antenna is connected) ?
Is it only a software limitation due to android support that doesn't enable "auto 20/40" bandwidth on 2.4GHz ?
is there a mysterious and unknown configuration setting somewhere to enable the 40MHz on 2.4GHz ?
I confirm that 40MHz is supported at least with 5GHz carrier (you must first enable "auto 20/40" on your router and well choose your channels).
Why it is not enable at 2.4GHz ?
Maybe is there another alternative ROM that supports that ?
Thanks a lot
I have the same question for SGS4.
Have you managed to find out anything?
