Wi-Fi! what is it? what can i use it for?

i am abit of a noob, what can i use wi-fi for?

basically its wireless LAN, wireless local area network, ie be able to connect to a computer network wirelessly to surf the internet, get emails, file transfer ans in some cases perform synchronisations.... beats the wired connections but can be a pain at times connecting to some wireless routers (access points) and even more of a pain to fix when there is a fault
At present there are 2 standards allowing fast ans faster transfer of data, b and g respectively. Some devices like the vario only supports the b (slower and older standard) whilst the other variants support both standards, as such yuo may have seen posts where people have deliberately changed ROMS (the software that operates the device) just to be able to connect to a 'g' network
Hope that helps

when i have wi-fi switch on do i pay anything?

sometimes you have to pay for it, but at most of the places its free. And it is not a GSM based service
thanks

It's free at home; I never saw the need on a phone till got a wi-fi connector. Now I listen to MP3s surf the net everything (super-fast and free). Definately worth it

wifi painfully slow...

I'm not sure if this is normal or not. I just got my Cingular 8125 and the wifi is very slow. I don't know how to measure the actual speed but for instance on my broadband connection, going to Google.com opens up in about a second. On dial up it takes about 5 seconds. However, on my phone using wifi, it takes about 20 seconds. When using wifi on my laptop, it is comparable to my broadband speeds my router is connected to.
I have pretty slow GPRS service as well and wifi is comparable.
I get the same slow speed on 802.11b as well as 802.11g networks (g network with registry hack)
Is this normal? The wifi speeds with the unit brand new out of the box was very slow. I flashed the rom and even overclocked to 240, the wifi internet is still painfully slow. I don't really find this useable. If I go to a page with images and such it can take a minute or so.
Anyone have any suggestions? Are others getting good speed on wifi. I tested by watching a streaming video and the speed shown on the bottom of windows media was 18k.
Were my expectations too high? Is there a setting I have incorrect?

Always best to be sure that you are actually using the wifi connection - Try disconnecting the gprs first before you connect to wifi. I have an issue where if I leave my gprs connection enabled all the time it takes precedence over my wifi no matter what.

Tried that but still no luck. When connected by wifi, I see the little wifi icon on the title bar. When connecting to GPRS, it shows the E and actually a pop-up saying it is connecting to GPRS. This part is actually working great. Uses wifi by default when wifi is on and GPRS is not.
I did try to disable GPRS entirely but still get the same slow results.
I also changed the wifi setting to maximize performance instead of save battery life. Didn't seem to matter.
I may experiment with Opera Mini or something to see if I can get some improved speeds.

no problems with wifi here. getting a faster connection than GPRS, even at hotspots.

I had a problem with my wifi connection in that the DHCP server giving out an incorrect address for one of the DNS servers. This made the wifi slow, because Internet Explorer kept on trying to lookup the IP of a host using the broken DNS, and then falling back to the second in the list.
You try specifying a DNS server manually to diagnose the problem.

Cingular 8125 WiFi Fix that works!
Believe it or not the support for this product from HTC, the mfgr, is great and fast! That being said, I like most users have spent days hunting for solutions to the problem and you will not find them anywhere. But here is the solution:
First you must have an unlimited account for data usage or forget your WiFi...well at least simply. Also, you must get Cingular to flip a switch for your 8125 to automatically switch from WiFi to GPRS and back depending on what is the best signal. It works great once the switch is set.
The only way I found to do this was to call support and make sure you get to the HTC support group. They will guide you quickly through getting setup but you must tell them about the switch so they call Cingular and have the switch set. For some reason Cingular, no surprise, does not seem to know about this when they sell you the plan and the phone.

Thank you so much. This sounds like the solution I'm looking for. So are you saying to call HTC support and they will contact Cingular to have the switch set on my behalf?? Or do I just call Cingular and tell them to "turn the switch on"?
I do have an unlimited GPRS for data usage.

what a crock of steaming brown stuff :x .... what exactly does wifi have to do with your telco? ... nothing. There maybe some registry entry that Cingular have set when the device ships which causes poor WiFi speeds but your GPRS data plan has nothing to do with WiFi data, unless you are talking about connecting to Cingular WiFi hotspots. The only changes needed will be on your device not within the Telco network.

before calling support, try this:
Go to comm mgr and turn off the phone. Then turn on WiFi and let it connect. Check your speed with www.2wire.com. If your speed is still slow, and another PC connected to that HotSpot isn't (test the PC with 2wire also) then your 8125 is bad.
Using the WiFi icon v.s. the "E" icon is no way to determine what wireless system you're using btw...

Ok, I tried 2wire. My laptop connected to my wifi network and clocks in at 3.2Mbps and my 8125 is showing 221 kbps. multiple tests showed 228, 205, 220). Perhaps it is unrealistic to expect similar speed as my laptop.
I turned the com manager phone back on and connected via GPRS and the speed test came back at 64.8 kbps.
So it does look like this method is working. I can live with 221 kbps.
By the way, I emailed Cingular and HTS. I got the following response from Cingular:
Thank you for contacting Data Support!
There is an additional setting that you need to enable/disable manually every time you switch between GPRS and Wi Fi, please take a look at it:

I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi.

"I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi."
No no no no no no and no.
small bus interface? for heavens sake... you have heard that there is something called a "bus" inside computers and that it is used to "transfer data" and this "bus interface" is small in the qtek so it is a viable candidate to blame slow transfers on.
no.
any memory bus designed after 1980 is capable of 200kbit transfers.
the main reason for the horrid speed of the 9100 is the stupid software design where every system call in a program gets interrupted by the os which in turn, after checking who-knows-what, in the name of "security" and "stability", and then executed. Of course this hinders performance dramaticaly without affecting stability and security a single bit: it still crashes. the difference is that it is also slow.

I'm running Xelencin's custom 2.17 ROM for T-mobile on my 8125. His ROM sets the device up to work with an 802.11 g wifi connection. I kid you not - I have measured 900 to 1200 Kbps on my wifi at home (comcast) and at work (T1). It's blazing fast.
To measure your speed, go to www.dslreports.com. Click on the lowfi version at the top of the page. Then click on speed test. Then choose either 600K or 1 MB and then let it do the test.
You may have some setting wrong.

I have an 'adhoc' wireless network (running at 11Mbs) and i stream large lossless (FLAC) audio files to my Squeezebox 3 wireless music player with no issues whatsoever.
However, the MDA can't cope at all. FLAC files play great from the MiniSD, but wifi performance is worse than terrible.
Yes, the wifi speed of the MDA is s**t.
That said, if anyone has any tips on how to increase perfomance please let me know!
Thanks.

My Wifi would not work at all when I updated my ROM but this utility fixed that and sped things up. I recommend backing up your device before executing because I have only tried this on QTEK 9100 with a beta 2.8 ROM.

Excuse me for my ignorance... But then how do you explain that the 6700 can handle 700kb wireless while 9100's usually around 220kB? The Intel proc on the 6700 seems comparable to the Omap,no?

What exactly does this cab change?

Reconfiguring DNS may make a significant improvement?
I came across your post after my own concerns with my I-mate K-Jam (Wizard) WiFi performance. My GPRS connection was at least twice as fast.
My problem was that is was taking at least 30~60 seconds to locate a web page and another 10~15 seconds to open the page. Once connected it seemed to work OK but operation via GPRS was still faster.
My K-Jam has a ROM that permits G connection and my AP is set to G only. After reading all the articles in this post (and others), I ran the 600K download at DLSreports.com. To my surprise, my download rate was actually + 500kbit/sec which lead me to believe I might have DNS issues.
I used vxUtil (http://www.cam.com/windowsce.html) to check my DNS settings. My primary DNS being picked up from my DSL modem was the DSL modems gateway address which works fine in my Toshiba laptop. My secondary DNS was my ISP's backup.
I reconfigured my DSL modems DHCP server so that the DNS servers being dished up to my K-Jam are my ISP's primary and secondary servers and I performed a soft reset.
The speed increase was substantial! Pages are located and opened within 5 seconds now making my WiFi connection useable.
This may be worth a try for others with similar issues?

Wifi sucks on touch HD

When I first bought the touch HD I was thinking how good it would be to have this phone while having wifi with the lack of 3g for tmobile in the us, but it turns out that the wifi acutally suck! I have a iPod touch 2g And the wifi works great with blazing speed. I can't seem to detect my wifi at home mean while I'm connected on my wifi with my iPod. I been very disappoint with this phone for simple fact that this phone recieves wifi poorly. Anyone can help me out with this problem would be much appreciated because despite the wifi problem I love the phone cause the 3.8 screen is so damn sexual lol.

I've no such issues!
Try to set wifi power options to performance. Also, Enabling G Mode (with SKTools is one of the ways) helps improve speed.

Thanks for the info but it might be the lack of range of my router cause I have been on my wifi with the phone before but I get disconnected frequently and most the time it doesn't even show up or detect it but I don't have that problem with the iPod. With iPod I seem to get wifi everywhere. I'm starting to believe the iPod is better might sell it and get a iPhone or maybe a hero but don't know if I'm willing to spend 600+ on another phone

Next time put [rant] on the title

My wifi connects well to open, WEP, and WPA connections. I tried numerous access points (at least 30), even 802.11n APs in mixed g mode. It even connects to Apple Airport (802.11g). The connection is stable both on power saving and best performance, but I think I get much better speeds on average with best performance.
Its wifi range is much better than my little HP 613 smartphone, but again worse than my notebook. I get 54Mbit connection with signal quality of about 50% at 10 meters through a wall and then it automatically finds another channel on another AP. It roams (handover) APs better than some Lenovo r61 laptops around!
But I am not satisfied with its speed (even on best performance) - it finishes copying a 700MB file on a 54 Mbit connection in 30-40 minutes using total commander and saving on storage card. That means average speed is around 300-400KB/s - laptop does the same (same AP, same file, same network settings) at 1.6-1.8 MB/s in around 7 minutes.
I also noticed that saving on storage card is slighty faster than into the main memory...

I can't seem to detect my wifi at home mean while I'm connected on my wifi with my iPod.

Hmm, are you sure that you don't compare two different situations ? Did you also try connecting to Wifi with your iPod while already being connected with your Blackstone ?
My personal experience shows me that the Touch HD seems to have a better radio than the iPhone 3G. Have you upgraded to the latest Blackstone stock ROM and radio available on the HTC website or XDA Devs ? Whether or not the radio also affects Wifi unfortunately I don't know.
Moreover, use WifiMonster to monitor the strength of the signal, it'll help you discover the best spots for using Wifi. I even receive Wifi signals from the neighbors' houses in my own house (not speaking about appartments), of course that always depends on the room !
BTW I'm pretty sure that a Hero won't solve your problem, it's the same old hardware specs as on the Blackstone.

The Wifi on my device works perfectly and i have had no issues at all with signal or quality. I have had more problems with my ipod than the HTC, are you sure its not the WIFI AP you are trying to connect to? Also are you using stock rom or custom?

I'm using the Energy ROM. I'm assume its my wifi signal its very weak and my touch hd cant seem to detect it. With my ipod i shows up and i can connect to it...will updating the radio make a difference?

I came across a startling discovery the other day regarding the Touch HD wifi. I was also having issues at home with weak wifi signal. I didn’t seem to have this problem with public access hot spots.
I have a Logitech wireless mouse connected to my computer and very rarely turn that computer off. I found that when my computer was off I would get a rock solid connection to my home wifi, but when the computer was on it would drop in and out. I narrowed it down to the wireless mouse was interfering with the Touch HD wifi connection.
I tried all different channels on my router, but as long as the Logitech mouse was plugged it I would get wifi dropouts. But as soon as I unplugged the mouse and the radio dongle, I wouldn’t have any problems with the Touch HD wifi.
I can’t comment if this is your issue, but something might be interfering in the 2.4Ghz with wifi.

Guys,
Sometimes even cordless phones, microwaves, etc will interfere with the connection.
Cheers.

As Poison Wolf correctly pointed out, other household items can interfere with the wireless frequency. Try changing the channel that's being used to transmit from your box (This will involve changing some settings on your wireless router so do some research before you fiddle around with it) I have had to do this before and can confirm it can make a massive difference.

Everybody has this problem because the card seems not capable of more speed.
But it seems nearly nobody cares.

Stron,
Hmm, interesting. The only reasoning I can think of is that perhaps there's a limiting factor in order to reduce the heat or something? I don't see why they would cap the speeds.
Cheers.

What if it is capable of connecting at 54 Mbit, but can actually do only 11 Mbit? Nice trick. I hope it is just a bad idea.

can i use with a 802.11N router

hi all i have read that the htc hd2 with a reg edit can run wireless N but is this true, can i use with with a 802.11N router, or will it only work with a 802.11G router,
i need to know as i plan to buy a long range router for work so i can stream DI.FM radio to my htc from my pc and the distance is around 50meter so i want to buy the bets possible router so i can listen to the radio glitch free
info on work network:-
1) 6mb speed via a cable
2) approx 50meters from where i walk / work

It might work at 802.11N standard, but unless your broadband speed is greater than 54Mbs then you'll have nothing to gain. Your router should be backwards compatible to allow 802.11G connection which the HD2 definitely supports, this should be good for speeds up to 54Mbs dependant upon your connection quality.

You'd still get the benefit of greater range, which would in turn mean you'd get a stronger connection. Even a really strong wifi connection on my PS3 only gives me about 700KB/s, despite being on a 20Mb connection (which I can use fully on my wired PC).
I do think, however, that 50m is somewhat optimistic, despite the claims of how good the signal should be (I believe it claims to do 250m outdoors!)
I'd love to try this myself, but don't have a wireless-N router, so can't. I'd be very interested to hear how you get on with this.

Works with ~700kb/s*
I was sending data between laptop and phone with wifi only.

well im going to take my THOMSON TG585v7 i have for my home internet to work i got it with my bethere internet, for free of the provider so im going to try it and see what i get with this,
i have no idea how good this router is though
http://www.thomsonbroadbandpartner.com/dsl-modems-gateways/products/product-detail.php?id=161
it says Typical Indoor coverage: 60m

î use a BELKIN N1 http://www.belkin.com/pressroom/releases/uploads/07_11_07N1Vision.html
and my HD2 has no problems connecting

how far indoors do you get a signal

router is downstairs and even when i'm upstairs i still get signal

Same. Got a Linksys WRT610N. With N-band enabled, not only is the signal strength better, but surfing the net and leeching YouTube vids just flies even though the Internet connection itself is only 12Mbps.

ok all ive decided to buy this for my work to send a N signal to my phone
http://www.scan.co.uk/Products/Edim...multi-function-wireless-access-point-repeater
my broadband speed is only 6mb at work but i just need the range so i hope this will get me at least 50meters walking distance lol.

Seems to only have 2 (small) antenna's though.
My Asus WL500W has 3 antenna's and has a great signal; whole house and garden covered.
http://www.asus.com/product.aspx?P_ID=nrsjewu78wdDXMOA
Running DD-WRT this beauty does it's job very well.
You could, if the signal is not strong enough or has to get through walls, consider getting a directional antenna to hook up to your router.
This will greatly increase the range.

[Q] Epic 4g and PDAnet.

I have successfully tethered my epic to my computer and can download at about 40kbps from the device. (Even 3g in my area is poor)
Now that is not really that important to most people but considering my max download speed with my DSL is 130kbps it makes a huge difference.
Now hypothetically with both DSL and PDAnet connected I should be achieving somewhere around 160kbps.
I am using Vista and both connections are active and show up in the Network Manager but It doesn't seem I can "combine" the bandwidth of the two. I have tried "Merging" the connections and also "Bridging" them.
For example I'm downloading a steam game right now. Its at a steady 128kbps I can look at the status of each of the connections and it doesn't seem I'm pulling anything from the phone. But when I disconnect the DSL I can pull 40 from the phone.
I know its slim pickins on both ends but any extra bandwidth I can get will help. Why can't I combine the bandwidth of the two successfully?
By the way, this is my first post here. I got my epic about a month ago and have been lurking ever since. I look forward to hanging around here more and thanks for any suggestions in advance.

You are going to need to share that connection via wifi to a wireless adapter hooked into a dual wan wireless router with your dsl hooked into the other wan input.
While hooked up you will most likely have to disable dhcp and somehow manually configure the ip's on both connection to the router with load balancing enabled.
In my opinion this is hardly worth any of the trouble and alot harder than what I think you would be willing to want to deal with in the long run.
I would consider possible upgrading your dsl a little faster and just consider your cell connection a convenience for when you need it elsewhere other than home.

Yeah doesn't sound worth it...
1.5mb DSL is the highest available connection here which is what I have.
I've been complaining for 3 years about it heh..
Thanks man..
