[Q] Galaxy Tab (P1000) Wireless-N Speeds at 5ghz... (What are your results?)

[commenter]

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"

"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?
