Interesting question...

Alright... here's my situation. I own a mobile business and bring a laptop with me on my route every day. I'd like to set it up so that I can print my invoices from my computer.
I bought the Lexmark Z418 with wireless capability.
Here's the problem: I currently just tether my connection (via bluetooth) from the kaiser for occasional web browsing; howver, I don't have a wireless network set up (no need when simply tethering). BUT I have to have a wireless network established in order to be able to print to this printer.
Should I:
A) Buy a wireless router and route my tether from the Kaiser to the Laptop to the Router and finally.... into a wireless signal (HAHA)
B) ????????? Help. Please? Any suggestions or ideas would be sincerely appreciated!
;-)

on my
can hardwire connect the laptop to the printer?
I forget the name but there is a programv that simulates a "virtual network"

It does come with a USB connection but that pretty much defeats the purpose the way that I have everything set up in my vehicle. :-( I have to do it temporarily for now and it's a pain in the neck.

if you can't make a virtual network perhaps your going to have to keep it hardwired you could get a long cable and run it realy nicely ie under the seat along the frame so itss not so noticeable
why is wireless so important? by the way

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

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.
Sent from my GT-P1000 using XDA Premium App

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?

[Q] wifi antenna external?

was wondering if there was some kind of external wifi antenna that maybe uses the usb/mini usb. most of the ones in the local electronic stores are for windows plat forms and im pretty sure wont work.

Probably not because they would require drivers.

Smart repeater

Doesn't phyically connect to your tab, but, if your looking to extend your range/reception in your house you could use an amped Wireless Smart repeater http://www.ampedwireless.com/products/sr300.html. I actually chose the access point version http://www.ampedwireless.com/family/accesspoints.html for my house to improve the wireless signal on the second floor. Works great.
The difference between the access point & repeater is the a/p requires a phyical connection to the network & the repeater doesn't. Max throughput on a/p is 300mbps & repeater is 150mbps (since it has to transmit wirelessly to your existing router & wireless clients).

thanks, i definately didnt want to have anything hangin off my tablet, kinda defeats the purpose, i like the repeater, ill check it out

Cheap mode: any router that supports DD-WRT - just put it into 'bridge' mode.
Fancy: the new Cradlepoint CTR35 can work as wifi repeaters as well as a hotspot

[Q]Wifi speed can't reach 802.11n

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.

chrome tab over wifi

So my PC is connected to my router by Ethernet cable. I can cast my chrome tabs and watch video play smooth with no issues. If i use my laptop that has similar specs as my pc and i connect via wifi, video will play very choppy on my tv. I have even tried it right next to my router to ensure the highest speed. A friend of mine is having the same issue with his computer which is also connected over wifi. Even at the lowest video settings its still choppy. Is this a known issue with trying to cast your tab over wifi or am I missing something?

I'm guess that if your router is not an "N" router (802.11n), it's probably having a hard time taking the stream from your laptop then sending it back to the Chromecast (I could be wrong). I have an N rounter and can stream wirelesly from my desktop to the chromecast with little to no stutter.
Also, make sure your chromecast has a good wifi signal. I had to use the included HDMI extender to give mine a little extra boost in signal.

Instead of telling us it's similar specs, what are the actual specs?

Yes my router is a "N". I have a Cisco E4200V2 which is a pretty good router.

Is your tab configuration a little low? Try another tab one more time,if still choppy,that is not issue of tab but TV.

My chromecast doesn't move and it has enough wifi signal to stream when using the ethernet connected computer so it should have the wifi signal. How would it be the tv? It works fine with my desktop.

Wireless connection will always be less reliable than a wired connection. I also doubt that your laptop has the same specs as your desktop in reality. Also, keep in mind that the tab/screen casting feature is still under development and not entirely reliable.

Yea i am hoping that when it comes out of beta it will be better over wifi. my pc (6 years old) is has a core 2 quad and it runs perfectly. My friend has a less than 1 year old mac that is quad core and has the issue over wifi. Theirs no way his 1 year old mac is not strong enough to support chromecast. I was ready to say "oh well it doesn't work over wifi smoothly" however it seems some people on here are claiming it should.

Even with good N router, you still need to setup right
For example use only G and N mix better yet N only
Set router to use 40MHz instead of 20Mhz
Use WPA2 AES for security instead of something else
There are tons of optimization that you can do to the network.
Best way is to hack your router firmware and replace it with DDWrt
There is a large community full of people over at DDWrt that know their wireless stuff.
I have a D link router cheap but hack with DDWrt and I am streaming ok
