WIFI Spectrum analyser, is there one?

Bit of an obscure request but any thoughts as to if it is possible to use the Wifi in a Tytn to scan for any wireless signals in the 2.4Ghz wifi band.
I already use sniffi but it only shows channelised info.. I need something that can show sigs from video senders etc in the nearby area...
If I'm trying to get a flakey router talking to a pc it would be nice to be able to see what else is around..
Any thoughts chaps...

Not possible on your tytn... it will only see IEEE 802.11 packets.
Google "wi-spy" for a cheap and nice solution, but not using your PDA

Wi Spy looks interesting, not sure if I can justify the cost at the mo' ....
Looks like I'll have to carry on just using sniffi for now as mini stumbler doesn't seem to work, well doesn't see the wireless chip/card in the Tytn and I can't seem to find anything else better..
Will think about WiSpy in the new year.... Cheers

How to improve wifi range ?

There are any tweaks to improve the range of wifi in universal ?
I have already set to maximum in wifi settings the option "optimize for perfomance"
Do you know some registry tweaks or chip hack tecnhics to improve wifi range ?
My friend nokia n80 and my laptopt as far more range than universal.
Just for comparassion the nokia was floating arround excelent and good signal , and my universal was no signal / poor signal and can not connect to internet...

It's not just you..
I think the WiFi range on my XDA IIs needs improving, but I don't know if its a hardware or firmware/software issue..
I've just "upgraded" from a Dell Axim X3 with which I used a Sandisk 256Mb+ WiFi SDIO card and my WiFi range has dropped dramatically.
So why the move?
a) WiFi SD meant swapping SD cards around all the time
b) no bluetooth on the Axim X3 that I had
c) tired of carrying a phone and PDA
I've seen mod's and upgrades on this site, but often it's unclear which devices they're suitable for... Of course, I try the WiKi for BA first..
Help please?

Well, From my experiences, the Universal's wifi range is almost as good as other wifi devices I have... as long as your wireless router is put in the right place.....
I used to have great problems with my universal's wifi connection, it's just not xxxxing stable, I mean it was connected a min ago, and then it disconnect whenever I use it, and I have to be in that very same room with the wifi router to get a stable wifi connection
Therefore, I bring it to the customer service for over 5 times, the repair guy just keep telling me everything is fine, everything is good, your wifi on your universal is PERFECT! And the dan thing is, it work perfectly for over 30 min in their office.
so I kept changing my wifi router, and another..... but then after some time, I found out all I need to do is place my wifi router indoor, Do not place it near/next to any window, but maybe put it in the middle of the apartment/house/office ....
I found out the Universal is easy to disturb by ANY interference, and place your wifi router near/next to your window will somehow do that. Once I place the wifi router "indoor" everything work just fine
try that, I am pretty sure it will work

Please let me know if it help ?

Re: Repositioning WiFi Router
Sounds like a good idea, thanks. I'd have to do some fairly major re-wiring to move my wireless unit though as it is the ADSL modem also and in an office which is not in the main house. Maybe I will have to buy a 2nd wireless unit for inside the house; I have a wired connection between the office and the house.
Strange, though. My Axim would always connect from certain rooms in the house, now by BA doesn't. Perhaps the antennae in BA's need improvement

Relation between GPS and Wifi

Is there any relationship between Wifi and GPS ???

any suggestions??

I am not quite sure what you are looking for, but the short answer is "no". Wifi is a short range wireless access method, typically 802.11g or 802.11b used to connect devices to the internet. See http://en.wikipedia.org/wiki/Wi-Fi
GPS is "Global Positioning System", a series of 24 or so satellites in orbit above the earth that provide precise timing signals that can be used to locate a received within a few meters. See http://en.wikipedia.org/wiki/Global_Positioning_System for details.
There are some applications that use the IP address of a WiFi signal to provide rather coarse location information.

Thanks for reply ....I was wondering whether A wrong GPS settings may affect Wifi CONNECTIONS as both GPS and Wifi use someform of data connections.......

You are talking about GPRS, not GPS!!!!!!!!!!
The GPRS and WiFi are on completely different frequencies.
NO, GPRS settings wouldn't effect WiFi.
However I think what you might really mean is modem settings and yes, if you don't configure the modem correctly then both WiFi and GPRS data wouldn't give you internet.

Thanks alot ....but I still mean GPS but NOT GPRS.....WHAT I am looking for is would faulty GPS SETTING LIKE PROGRAM PORT OR HARDWARE PORT AFFECT WIFI CONNECTIONS???

gps dont send anything it's a passive reciever which listen to the satelites it dont send anything back or to anywhere

Thanks alot .....

That's right, and on an airplane, the stewardesses will make you turn off a passive GPS receiver, but PDAs, PCs, phones, and some mp3 players are on generating bluetooth and WiFi signals all over the place.
Ignorance of technology... where a basic understanding should be in order.

I don't notice any difference between gprs and wifi,you can use both to go on the net,i don't bother using wifi .(risks being a butthead)

Would it be possible to modify/rig a gps antenna to boost the recieved wifi signal?

No. Completely different frequencies and totally different antenna. aGPS does speed up your gps precition though becouse it uses the mobile phone poles to calculate your location in the same way your phone would use the satellites, except much faster because it's closer and in better range. So... Phone towers can help locating you (but still doesn't help GPS) and GPS can't help WiFi or mobile connection because of different frequencies and thus different antennas.

Many problems with my GPS but never with Wifi.
Anyway, these two are totally different.

Sometimes Navigation Apps will prompt you to enable Wifi to lock in to your current location faster. It is understandable to enable it. Turning off Wifi will not hold GPS capabilities down. at all

[Q] A-500 Antenna

Does the A500 support a USB antenna--if so what do you recommend

A USB antenna, as in, a WiFi antenna?

what is a USB antena ?

Normally, it's a dongle that plugs into a USB slot. You can buy them just about anywhere and use them on just about any computer - but typically you use them when you either don't have a card installed or don't want CAT5 running around the house.
I don't know why one would want one for the tab as it has integrated WiFi.
I have a feeling he meant 3g.

Yes a WiFi antenna so I can increase the ability of the tablet to connect to weak signals.

I don't think that would be supported. WiFi dongles typically have software that has to run alongside them and there's nothing like that for our Tabs (or any Tabs for that matter). That I'm aware of, anyways.
If you're looking to get a stronger signal at home, get a WiFi booster(s) and place them around the house in areas that have poor signal - as for trying to increase signal strength in public places, you're sol.

put ddwrt on old router like linksys you're set for wifi repeater

I know this thread is old, but I did not want to start a new one. Had anyone ever seen this: roklandllc.blogspot.com/2010/10/bearextender-n3-wi-fi-usb-adapter.html ?
Apparently they had the device work, just by plugging it into a Android device called a FlyTouch 2. I wonder what it is about that device that allows it to work. I think they noted that the FT2 was running 2.1 I believe on another site.
I do not know if it would be more of a burden to have an external Wifi, but it is interesting. I am thinking of buying one if I can find it on sale next month, when we have money.

people are getting bactrack working and that has built in support for the awuso36 wifi adapter

Wifi antenna location

Ive been trying to find out which contacts in the samsung s4 are for the wifi antenna, so that i can look into attaching an external higher gain antenna. Ive seen the cable on the side called the wifi antenna cable but upon disconnecting it i didn't see a drop in wifi connectivity, can someone confirm that this is in fact part of the wifi system. When i unplugged the cable i only lost cellular connectivity. Can someone post pics or draw n a pic to show where the wifi antenna is inside the phone. Thanks
