I connect Galaxy Note to my 802.11n AP
But the connection speed only 65mbps
My desktop PC connection speed is 270~300mbps
Why Galaxy Note Wifi speed is so slow?

You need to understand how 802.11n works. To achieve 300mbps speed, you will need 2-3 spatial antennas which can be found on modern laptops with Intel Wifi chipset (such as 6300). Our galaxy note has only one antenna (should be 1 for each radio band (a/n, b/g/n), but it is "N" compatible. So your speed is actually pretty good on a single antenna.
Unfortunately this is a case of the manufacturer misleading it's customers (tbh I would say out right lying to us).
As the above poster mentioned the note is compatible with N, however it can not support N speeds, as far as I have seen all phones that claim 802.11n are actually limited to 65mbps. So really are not 802.11n at all, rather just a little faster than 802.11g.
Although having said that unless you are transferring huge files across the network, streaming multiple FullHD streams at the same time, 65mbps is going to be sufficient.
its really misleading, i got upset when found out, also i have the impression that the battery drains faster on n without giving me any faster speed than on bg, maybe one day someone builds a phone with real fast wifi

For further detail on this issue I found this post helpful
I have the same issue with a Galaxy Tab 10.1
does anyone know if it is the same reason ?
how many antennas has is and what should be the max link speed ?
I have a wireless N router, and with my desktop (that's connected via wifi, I have 2, one wifi and one RJ45) I get 300 megs (connection speed) and when I connect via FTP From my phone to my desktop to download files or sync files, I get about 2.7 megs. I'm right next to the router (about 8 feet, clear sight) and the desktop to which I'm syncing is connected via LAN.
I also have this question about what need is for that on a phone. I can view HD videos from Youtube though my slow ADSL and the normal WiFi. You only need 1 - 1.5 Mbps for that.
Even if you were streaming 1080p with 5.1 channel sound, you don't need 100 Mbps.

I'm trying to find a way to use my Iphone 4 data plan (3G) on my Samsung Galaxy Tab 10.1 (Wi-Fi Only) through the USB cable/adapter but no luck so far.
I'm currently using the ROM Task Rom 9.0 on the tablet so Ad-Hoc is enable and I've been able to tether to the Iphone through Wi-Fi, however it drains my phone's battery pretty quickly.
I do have the Samsung USB adapter but when the Iphone is connected to the GT it only allows me to copy photos. It doesn't recognize the USB tethering.
Does anyone have any tip or advise???
I guess the same procedure could be applied to any cellphone regardless of the OS.

Note that this is the ORIGINAL 7" Tab section - you might have better luck in the 10.1 Tab section.
Other than that can't help sorry
I hadn't noticed sorry.
Thanks anyway.
Currently been using my Nexus with my GSII and bluetooth tethering for internet access, thinking that bluetooth being lower powered, short range, its probly less demanding on the phones battery.
Does this still apply to modern devices with combined radios?
Also has anyone found a widget to connect/reconnect to a paired bluetooth device?
I think the nexus is going to deep sleep, and closes the connection to the phone. But it doesn't bring it back when it wakes...which means its Settings>Bluetooth>Click on Phone...which is 2 clicks too many!

just got it set up, it works great! Thanks for this, I was using Wi-fi tether the other day, killed all 3 of my batteries
I've been using WiFi tether at work; are you guys saying that using Bluetooth tether is less cumbersome on the battery?
I've been trying bluetooth tether all day today.
I have GSM Galaxy Nexus running official 4.1.1
Nexus 7, on 4.1.1 also.
I get them bluetooth paired up and bluetooth tethered via the Galaxy Nexus' cell data.
It works for like a minute then after that, they would disconnect (unpair from bluetooth).
Been doing this all day long every time I try.
Also the 2 are only 3ft away.
Any Ideas?
EDIT: Just saw this URL from another post.. guess it's a bug: http://code.google.com/p/android/issues/detail?id=22369

Same setup, and same issue.
On a side note is there a way to use NFC to automatically pair the two devices via Bluetooth? I'd like to just touch them together and voila they are paired?

Just to pair normally? No.
But if you beam a picture, it auto turns on the bt, pairs, sends the picture, then turns off bt. The two devices does not have to be paired up beforehand either.
Google did show off new feature of NFC/BT at Google I/O during the sessions.
They showed off headphones and speakers that when you touch your JB device to the headphone/speaker, it auto pairs and audio starts playing.
So yes it's possible to auto pair devices, but those other devices need to support it.
This is a known bug with the galaxy nexus phone. It will kill BT tether when the phone goes into sleep.
Download an app called wake lock from the play store and set a partial wake lock and the problem will go away.
Your battery drain will be slightly higher though.

So far it seems to be, which it should as Bluetooth is a short range low powered protocol.
I wasn't sure that with the modern design in phones, when the radio's are all one chip, if the power saving would still apply.

Try turning off your WiFi before pairing....I think that worked for me
Are you guys using that PDAnet and FoxFi setup in order to pair the devices? Thats the only way I can bt pair my galaxy nexus and nexus 7 together.
mmm, nope its native feature in the Resurection Remix rom I'm using on my GSII
Not having any luck installing PDANet 3.5 on the Nexus 7, any ideas?
Got FoxFi installed on my HTC Desire and ticked Bluetooth DUN. Can pair it to tablet but tablet doesn't get any Internet access, so need PDANet installed for that I think.
Edit: PDANet 2.20 on the market was installable, bluetooth tethering working ok now. Really old version though...
Further edit: Looks like it is "PDANet Tablet" version I'm using, hence the confusion. 2.20 appears to be the latest one.
Just tested BT tethering on my N7 with my SGS2 (which was using wifi at the time). Worked perfectly. I did a quick speedtest and got 750kbps down and 1500kbps up (weird wifi...). I was shocked I would get such good speeds over BT. Anyway, I like this option better then a wifi hotspot. First, it's easier to setup. Second, it (apparently) uses less power. And third, it will allow me to access some special hotspots I might not get on my tablet. For example, with AT&T, they give you free hotspot access at some locations with their devices. I wouldn't be able to use my tablet there directly, but could daisy chain through the phone. Coolbeans.
Bluetoothkeepalive works to keep the bluetooth connection for bluetooth tethering. Just trying it out and hasn't dropped yet over about 15 minutes.
OK a little help please. First off nothing is rooted.
I have installed pdanet and fifox on my HTC sensation. I can connect the Bluetooth from my nexus 7 to the sensation but I can't get internet access. I checked the setting in the Nexus "Use for internet access" but still nothing.
What else should I try?
Thanks for your help

Go on the tablet, into Bluetooth, and you should see your phone in there, click on it. It'll then say connected. You'll get internet access.
I have now noticed that the bluetooth connection does drop after a minute or so, which can be a little annoying.
I'll try bluetoothkeepalive.
Another good app to get is Bluetooth Auto Tethering, it keeps tethering as an option on every time your phone boots, no extra interaction on the phone to enable tethering every time. Just enable/disable the connection from the tablet to automatically turn tethering on/off on your phone!

You might try going to Settings - More - Tethering & portable hotspot - check wi-fi hotspot and configure

You are right about that, I got stuck on doing that yesterday. As for the general discussion about bluetooth tethering vs. wifi tether. I tried it out today and I can say its much better on the battery life, but the speed is pretty low. I keep doing a speed test on my phone and couldn't get over 1.48 Mbps, then tried wifi tether and was easily getting over 5Mbps.
I have a D-Link DHD-131 Mainstage WiDi adapter, supporting Miracast because it runs WiDi 3.5 firmware (correct me if this is not correct). I can find the device, but when I try to connect the D-Link says that it has found a device that wants to connect and after a few seconds the message disappears. The Xperia on the other hand is just patiently counting down from 120 seconds to 0 and except that does nothing.
Are there any people that use Screen Mirroring? If so: did it work with your adapter? What brand adapter are you using?

I have tried connecting to a Samsung AllShare Cast Hub, which may not be 100% MiraCast compatible, but according to some video on YouTube it also works with the LG Optimus G Dual (also a 1080p phone)
I found the following issues:
Connection is 'successful' but screen remains black and no sound is transmitted
On one occasions I somehow managed to hear my phone's sound through my TV - haven't managed to do so since
WiFi is disabled (indicated by a pop-up message) as soon as screen mirroring is activated, and re-enabled after the screen mirroring connection is closed!!!
The first 2 items may be compatibility issues, but the third one surprised me and is probably a limitation in the Xperia Z. While the Galaxy S3 can have WiDi and WiFi active at the same time, the Xperia Z apparently cannot
Edit: note that in order to connect to the dongle, I had to press a button on it first. Before pressing the button, I would just keep seeing the same countdown timer you describe here. Maybe that helps somehow?

Hmm... My WiDi adapter had no buttons at all, only a reset-button. I tried resetting and pairing, but that didn't help. Thanks anyway for your reply, at least I'm not the only one having problems using the Xperia Z's Screen Mirroring function with 3rd party adapters... I wonder if there are any combinations of adapter/XZ that do work...
So on my phone s7 edge I play a game over my WiFi, i turn off the WiFi on my phone use the same WiFi for my tablet and play the same game but get crazy lag anyone tell me why or know how to fix it
My Galaxy tablet defaults to 2.4 GHz wifi - maybe that's the problem?
I have to turn wifi off then on again for it to connect at 5 GHz.
But the Xperia Z2 defaults to 5 GHz wifi for some reason - I dunno why the Galaxy Tablet won't auto-connect at 5..
