[Q] Forcing lower wifi connection link speed ? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I'm currently getting dreadful wifi stability on my SK17i Mini Pro while connected to my work PEAP wifi hotspot.
I've been poking around and I've noticed that the Mini Pro appears to always connect with a 54Mbps link speed and doesn't reduce it when the connection proves unreliable (by comparison my HTC Evo 3D is using a 19Mbps connection to exactly the same AP and is pretty much rock steady).
So I'm wondering if there's an easy way to force the Mini Pro to use a lower link speed (without altering the AP's settings, which I have no control over) ?

Samsung Smartview with 3g?

I like streaming TV (ES7005) to my SGS2 inside my home network but I'd love to be able to do it elsewhere too, for example with 3g connection or friend's wifi.
With OS Monitor (from market) I managed to find out that at least while streaming the connection is made to ports 55000 and 55001, but even if I portforward these to my TV I can't make a connectiong with 3g.
Is there any network wizard here that could make it work or at least explain why it wouldn't work without wifi connection?

Phone Tether for TouchPad

Want to use your phone's 3/4G data connection with the TouchPad? Having come over from the Nook Color tablet forum, I've tested the Nook Color Bluetooth Tether app on the TouchPad with 20120712 CM9 nightly, and it works. This app, available for free in Google Playstore, allows you to share your phone's data connection by pairing your TP with your phone. Nice when you don't have free wifi. Get it here:
Nook Color Bluetooth Tether
youre likely gonna miss out on some speed using bluetooth tethering for anything above 3g. For the bandwidth and latency, it all depends which version of Bluetooth both your phone and your tablet support, and what kind of network connection you're tethering. Your connection speed will only be as fast as the fastest standard supprted by both devices. more than likely that'll be bluetooth 2.0, and if you're lucky both will support EDR profile. that will max out at 3mbps. Sticking with wifi would be your best bet for 3.5g and up for sure.
thanks for the info

[Q] Is there a way to change network adapter speed and duplex on android?

Hello, i have one old aliuminium ethernet cable, when i connect laptop and router using this cable I have to change network adapter speed to 10mbps full duplex. When it's on auto (or any other setting) i get "cable unpluged" message. But I want to connect router with android tv box (geniatech m1 atv1000), but magic doen't happen. Actualy it's not quite a router it's a cheap chineese wifi repeater , and it doesn't have allmost any settings, so i'm wondering is there a way to change androids network adapter speed and duplex?
I cannot change the cable, because it's betonated inside of the wall..

[Q] Force 802.11g instead of 802.11n

Hi all,
I need to thether my 3G connection with my satellite linux-based receiver but I have some problems with the built-in wifi module (n standard).
Probably the drivers are not well developed but I experience some random lags (for example I ping it 2ms then 650ms the 45ms etc...) also with my linksys router.
I had to switch to 802.11g only in the router's option to have the receiver working properly.
But now I have the same problem with my S3: the receiver connects @ 150Mbps (so 802.11n) during the tether with the same random lags...
Can I select a lower max speed (a different standard, 802.11g in this case) in the Galaxy S3 (also with external tethering software, the phone is rooted)?
Can I set it for the whole wifi section (I think that also the tethering will go at that speed)?
Thank you very much for the support!
Same problem here
I have this very same problem with my SGS3. My older laptop can't use SGS3 tethering because it lacks 802.11.n. I would really love to know of a way to force 802.11.g tethering on my S3. I'm not capable to root my phone, so it has to be some setting or app.
Is there anyone that knows how to do this?

[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.

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.
