Hello,
Regarding dual-band Samsung Galaxy Tabs correctly operating on 5Ghz/40mhz...
Is anyone seeing 150mbit (or better) with their Galaxy Tab using 5Ghz at 40Mhz?
Only respond if you have a galaxy tab, and you know that you are using 5ghz. Also please quickly review ALL of the following relevant information before attempting to respond to the above questions;
According to the following search info the galaxy tab supports 5ghz dual-band wireless-n, and the overcome rom v1.6.4 supports 5ghz wireless-n also.
"Dual Band Wi-Fi"
http://www.google.com/search?hl=&cat=&meta=&num=&ie=utf-8&q=galaxy+tab+5ghz
"WiFi-N on the 5ghz band now works"
http://www.google.com/search?hl=&cat=&meta=&num=&ie=utf-8&q=galaxy+tab+overcome+rom+5ghz
Additional info:
I am using a Linksys e3000 (dual band) router, and can connect at 300mbit stable link-speed (file transfer speeds are 15MegaBYTE/sec average) using a Linksy AE1000 USB adapter (with any pc or notebook) which I purchased to resolve similar (speed/streaming/transfer) issues with the onboard single-band 2.4ghz wireless-n adapter in another device I was working on.
I have both 2Ghz and 5Ghz networks and devices completley seperated. 5ghz is operating at 40Mhz (specifically wireless-n) only (automatic channel) and 2.4ghz operating at 20Mhz (wireless-g only) with a specified channel that is not being used by any neighbors.
I do not have any issues with connection, stability, or speed/transfers with any other N or G devices...
I can connect to the 5ghz (wireless-N only) network with the galaxy tab although it is not very stable. Speed fluctuates btwn 11mbit and 65mbit, and is pretty much bunk for video streaming (standard xvids or mkvs) via smb/cifs using MoboPlayer (and others).
Both video formats (xvid & mkv) play fine locally via (8GB class4) sdcard upto 720p. 1080p mkv (using ext2/ext3 on a second partition on the external sd) are completely unwatchable on (16GB class2) sdcard. For that reason and the flakey 5ghz wireless-N speed which effects the (unwatchable) playback/streaming of even small 30 minute fast-motion (action and/or animated) xvids almost makes me want to return the TAB.
I am running Overcome 1.6.4 rom+kernel (froyo) and have no issues other than the battery life seems to deteriorate rather quickly (and it seems to generate more heat) while using 5ghz for long periods.
Has anyone here successfully connected at 150mbit (stable) or better (using 5ghz) with their Galaxy Tab (P1000) yet? And if so, was there anything extra that you needed to do to accomplish that speed and/or stability with this device?
Please review all of the above before answering, thanks.
bump. Anyone?
Couple of questions for you first.
1- How are you measuring your speed?
2 - You do realize that SMB/CIFS sharing is not the ideal way to stream video? Thereis much more overhead in you bandwidth versus say using a streaming server (ie Plex) or using a DLNA player/server to stream.
3 - The MKVs that you're streaming, are they all 720 or are some 1080? Do some have DTS? Both the 1080 and the DTS will cause playback issues streaming as both need alot of work done to be processed correctly by the device.
For streaming video I have found, after much testing, that anything that has DTS or is high bitrate HD content will cause thetab to stutter. I find that remuxing to an MP4 with AAC 2 channel audio and your streaming problems will disappear even using SMB.
Think of it this way, we don't have 1080 resolution nor surround sound, why even strain the device to process it. I use a Plex setup with an AppleTV using dual band N with a G signal as well and never have issues even over 3G. My router is a Linksys E3000 with Bell Fibe 25 down with 7 up VDSL internet connection.
Lemme know how you make out.

I just got a Linksys E3000, and I can't seem to get my Galaxy Tab to see the network at 5 GHz at all.
The E3000 is simultaneous dual band, and it's connecting fine to the 2.4 GHz network.
Did you have to do anything to get it to just connect?
Hey slimdizzy, thanks for responding to a question with a question.
If you pay more attention to the post you might notice at least one of your questions was already answered prior to your reply.
Correct me if i am wrong but the overhead in CIFS/SMB is minimal/insignificant in respect to my request/questions.
There is also no need to implement other technologies (client/sever software) to accomplish the task of streaming using pre-existing technlogy that has been used for numerous years over much less powerful (or capable) hardware or infrastructure.
The question is NOT concerning what technolgy to use, but rather what connection (and link) speeds people are getting over 5ghz Wireless-N, with this specific device, so if you cannot answer the question there is really no need to respond.
Thank you.
Again unrelated to my request/questions. (manekineko),
You might want to read the original post again more thoroughly.
See the second paragraph after "additional info" in the first post. Also notice I mentioned a rom/kernel that supports 5GHZ Wireless-N specifically.
Bump from the dead.
commenter, were you able to find a solution to this problem?
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.

What I am trying to figure out is if I can use my Droid Bionic as the internet source to my router, using the usb tether option.
I am trying to provide a stronger signal to other devices in my house, and to have a private network that will work my printer, satellte tv, etc.
Is this possible?
Not that i know of unless using the wireless tether and using your router to jump the signal.. if tour router supports it.
Sent from my DROID BIONIC using XDA App
Wireless signal repeating is a part of the 802.11n spec. If you have a wireless-N router there should be a firmware option to enable it.
Maybe USB tethering to a PC is the solution. The steps required after that might get complex, but in short your goal is to bridge that connection to your standard ethernet adapter on the PC.
Plug the ethernet from your PC into the router. Put this in place of where your modem typically connects and you should be only a few networking tutorials away from a configuration that works.
USB tethering isn't supported on your router most likely, or any router for that matter. That's why you are going to have to put a PC running Vista+ or Ubuntu 10+ (others may work) for interfacing the connection to a standard ethernet cable.
If a repeater is all you need this won't be useful for you.
Personally, I intend to configure my network to use the 4G connection's superior upload rate, as my ISP at home provides 3Mbps upload while 4G gets 10Mbps.
Using modified firmware on the router will make many things possible. You may want to check out DD-WRT (what I'm currently using) or Tomato.
Do you want both WAN connections (ISP and 4G) to be available to your network?
Sorry if I'm confusing anyone. =)

Just the 4g.
I currently use the wireless tether option, which provides me 4g internet access for all devices in my house, but I do not have much latitude as far as distance ( the further away the device is from the phone, quality of service declines).
I know that I can USB tether the phone using pda-connect, which works rather well. I just want to use my wireless printer without a lot hassle, and have 1 network that is complete.
Dan
USB.. Not without additional hardware people have already mentioned.
Your router can pick up the WiFi tether from you phone and use it. I have this setup at home with my LinkSys WRT54G. Its called "repeater" mode. I'm not saying it can do it with the stock firmware, but it can thanks to the DD-WRT firmware I loaded onto it. Just google DD-WRT. Many older routers can install it freely. They started charging registrations for some newer routers. That's why I bought a used WRT54G off e-bay for $20 bucks, since I didn't have a router anyways

I would agree with the previous setup also.
But really, there's no better router than a book and an old dusty PC.
I want to do exactly this.
Currently, I have limited functionality with an old cradlepoint router. The router works fine with PC's and mac's but not the iPad. I narrowed the problem down to the MTU setting which cannot be adjusted on the router or the iPad.
I was thinking about purchasing one of those sapido routers, but I'm not sure if it supports the bionic. The price is right though.
Any update on this thread?
Hey again gang,
So, I did it... I purchased a sapido router from amazon... this one to be exact:
http://www.amazon.com/Sapido-GR-173...OY/ref=sr_1_11?ie=UTF8&qid=1327437644&sr=8-11
I received the router yesterday and connected it to my phone and it works beautifully... better and faster than any other internet service provider we have out here (Time Warner, Local telcom, clearwire, etc...). Just to let all of you know too, I have the 901 ROM installed on my phone, so no more disconnects. I was watching veetle all night and not one hickup.
All I did to get everything to work was go into settings, Wireless & networks, Tetehring & Mobile Hotspot and check USB tethering. The router finds the connection instantly and the green light comes on indicating that we have internet!!
Ethernet and wireless work great to my desktop and laptop. I did try it out with my iPad. The connection to the iPad mostly works, but it does take forever to get some pages. To remedy this, if you do get the router, change the MTU settings from 1492 to 1400 and then everything works beautifully to an iPad.
Best of luck to all of you who decide to use your phone as the main source of internet to your home through the usage of the outstanding sapido router!
Thanks.
Howdy,
Same here. I went with the Sapido RB-1733 from Amazon. Works fine as a regular router, and I can plug my Bionic into the USB port and charge it while its using the tether option. Much better at having a full size router spreading your wifi around the house, besides wired networked stuff.
later...
Purchased gr-1733, but can not get it to work properly. Please tell me the settings you used to get this working. I am using verizon bionic with 4g.

I want to tell everybody purchasing routers that support USB built in: your existing network equipment (router) or any old, unused PC can do this for you free.
In fact, there are so many ways to share your 4G throughout your home I won't explain them in-depth unless there are specific questions.
Routers: many routers (Linksys, Buffalo, Belkin, NetGear, ASUS, and many more) contain hardware capable of running open-source firmware. My network contains many flashed routers: Linksys E4200 v1, Linksys E2000, Buffalo WHT-HP-54G, and Belkin F7D7301 v1. These models are all compatible with modified firmware. But keep reading...
ALL YOU NEED IS A USB PORT on your router. The firmwares (assuming your router is compatible) take care of the rest. Be warned, there are ways to brick your routers if you don't read the wiki/forum threads properly. In my opinion, these are much easier to flash than phones.
The DD-WRT supported devices list will let you know if you have a box *already compatible* with DD-WRT. Otherwise, use this reference to shop around for a router with at least:
8 MB flash
1 USB port (you can expand with a powered USB hub)
Support for optware (any Broadcomm router will work!)
This isn't very easy to find but almost any Linksys router has a broadcomm, for example. I can provide reference for any of you that might have questions.
Your router needs writeable space to keep a couple kernel modules that may/may not be built in to the particular DD-WRT flavour/build. Basically, this is something dependent on a per-router basis.
If you have something listed on the supported devices list, I will be happy to provide some reference on whether or not you will be able to do this.
USING A[N OLD] COMPUTER:
Get a linux distribution of your choice (I'll provide links on request)
Enable USB tether on your phone while plugged into a high-speed port.
Configure the connection to route out of your standard Ethernet adapter.
Plug your existing router's WAN/Internet port into the linux computer's Ethernet port.
And from here you troubleshoot. And I can try to help.
I will probably write something up on how to do this on my website once I get things running. For now, I'll subscribe to the thread and take questions here. I'd also like to point out there are many other creative ways somebody can do this. Just keep asking.
Good luck keeping your battery from draining faster than it can charge; I sincerely mean that. WiFi Tether can be killer if using it as a shared connection.

FXMech,
So i've had a Linksys E4200 for some time and after reading your instructions have flashed dd-wrt onto my router. There are a lot of neat features now available but i'm not sure how to get the router to use my phone at an internet source. I'm using a motorola usb data cable and have easy tether set to share my internet and when i plug it into my router i get nothing. any help with this would be appreciated.

Some advice on how to get Android USB tethering to work on dd-wrt would be much appreciated.
Using a Linksys E3000 - DD-WRT Build 19519 installed
JFFS2 Enabled
usbnet.ko, cdc_ether.ko and rndis_host.ko installed
Now stuck at this point.
Thanks in advance
Nice before I even read this I was doing usb teather to my computer. Then I would hook my router up to my computers ethernet port to outers internet port. I have windows 7 so I did network bridge and the router had internet. To bad you need the computer but other than that wifi on router is grwat. Lan is also great. I play xbox live from this setup.
Hehe, I was just going to find some reference on the Ubuntu equivalent of "Connection Sharing," and landed back here forgetting completely about how I've helped motivate this search result.
Here's the deal - I was wrong about a few of my previous posts, I am too lazy to retract and edit out the stupidity,
I have since discovered a fundamental flaw in my logic - "USB tether" is NOT equal to "USB modem" - don't ask me why. However, I can say I know the limitations now.
Bad news: All USB-capable routers supporting TomatoUSB ( http://tomatousb.org ) or DD-WRT ( http://dd-wrt.com/wiki [the main site is useless for regular people, stick to the wiki & forums] ) will not allow this. I have just confirmed in the DD-WRT Kong Mod build for the Linksys E4200 won't do it. To cut to the chase, this build included what I suspected to be the additional modules usually needed. Turns out, those modules are for USB modems, which is a separate type of subscription service, not to mention an additional Dongle to buy. I suppose it's useful for some.
I like to skate by on the cheap, so I won't be able to speak to these (awesome sounding) routers previous people bought. For those of us still wanting to have fancy internet sharing (non-phone-WiFi), you will have your answers revealed. Just not this post. I am not ready to tear down some of my excess equipment and get it rigged up quite yet.
I will be working with Windows 7 and Windows Server 2008 R2 machines at a later date. I anticipate no problems with either, and from my estimation the gist of what's required has already been talked about in this thread.
However, as the resident dork-in-charge of my home office - my specific interest lies in "multiple WAN" on my router. There are 2 reasons to do this. Redundancy or[and?] load-balancing. My new gateway since my last posts in the topic has switched from the E4200 over to an installation of Zentyal 3.0 ( http://zentyal.org ). Zentyal 3.0 is based on Ubuntu Server 12.04 LTS, so I suspect it is possible to tether.
I anticipate a lot of people might stumble here searching The Google. I figure I might as well write this out in a organized, thorough way. More to come as I make room in my brains to type out a relatively coherent tutorial for both OSes.
Sorry guys, 2 people flashed routers per my speculation. If I find any solid info in the future I'll check back.

I'd love the feature to use my usb ethernet adapter as the main connection for chromecast as it'd help with local streaming and maybe eliminate wireless latency issues
Well, it's been said there is HEC support to get HDMI Ethernet channel. Unfortunately, after a full afternoon of searching, you can't just make a cable. It's a separate protocol and you'd need a chip to translate the RJ 45 into HEC.
Not only that, I seriously doubt those chips are available to purchase in quantities less than 1000
Sent from my Nexus 7 using Tapatalk
Yeah HEC seems a bit overkill...
USB Ethernet adapter seems slightly more accessible, though only certain chipsets would be supported, and that's assuming there's enough RAM/storage and USB OTG doesn't dumb-down the USB connection any.
For example, my Toshiba Thrive (AT100) has support for a certain vendor's USB Ethernet adapter built into the stock ROM. Very convenient to maximum network bandwidth when I'm using it as a secondary display via iDisplay.
Well, dddtg and I were having the conversation yesterday and it seems the eth0 is supposed to be for HEC

as mentioned, me and tchebb believe the chromecast has built in support for HEC networking, as not only does the hardware support it, but a ethernet interface is active on each chromecast with a unique MAC address. We currently do not have the hardware to test it, so it can not be confirmed at this time.
As for USB Ethernet support with a OTG cable, at this time it is not possible. A few things would be required first for it to work:
Enable the USB Interface in the Stock OS with a custom kernel
have the proper driver compiled and added to the kernel, or loaded as a module
Make sure that all binaries in the chromecast could utilize the wired interface
The first part would not be too bad, but the issue is on part 2 and 3. There are many different manufacturers for USB Ethernet Adapters, and to compile and add every single one of their drivers would take loads of space and time.
As for part 3, all of googles binaries, while most open source, require propitiatory binaries that only Marvell can hand out, and as we don't have them if any of the applications are directly linked to the wired interface, there is no way we could easily force them to use a wired interface.
So tl;dr is it possible? yes. Is it easy or worth the work? not really. It would be best to just use HEC if its enabled.
Marvell?? Oh god

Well if a full HEC support was realized it could allow the Chromecast to serve as the Internet connection for all other Network aware devices that are HEC compliant in the home Entertainment system....
OR (and much more likely) Would allow Chromecast to use a wired connection from one of the other devices in the Home Entertainment system as it's primary Network access point.
The goal of HEC is suppose to be that only one device in the HDMI chain actually needs to be connected to the Net, The rest would all connect via HDMI instead.
But if you ask me it's probably a pipe dream to ever see it reach it's intended goal.
