Right then, I don't know much about secure Wifi, so I've just changed my access point to not broadcast the SSID. So, how might I get my MDA Pro to learn about the SSID if it's not broadcast? Can someone please give me a "for dummies" guide to the LEAP thing as I don't have a clue
When I was broadcasting an SSID, it all worked perfectly, pretty much automatically.
I cheated, i set access point to broadcast ssid just whilst i put the JJ on it, once on i turned off ssid broadcasting.
its seemed a bit flakey when trying to add it in the leap settings page. i tried both open adn eap and then just decided it'll be quicker just to enable ssid for 2 mins.
This is hardware dependent, of course, but I set my wifi router up to only allow access from listed mac addresses. That, in addition to hiding ssid (once connected) and 128 bit wep is about enough to stop me getting the crawling heebie-jeebies.
They don't call me paranoid mike for nothing.
Just because you are paranoid, doesn't mean they *aren't* out to get you

Interesting, and I think my router will do this. How can I determine the MAC address of the MDA?
OK, the following is on a blue angel but I imagine that the principle should extend to WM05.
Firstly, get the wep setup and copy the (uppercase) key to your ppc via AS so you can broadcast your ssid with relatively few twitches D).
Start > Settings > Connections > WLAN, fire up wifi and connect to your access point - in WM2003SE this means checking a tick box (or ticking a checkbox). Once you're connected, you should be able to see the ssid, tx rate etc as well as the mac of your wifi adapter.
Additionally / alternatively, your wifi ap may tell you the macs of all connected devices. The smart person would check this first and make a note of any devices and use this as a cross-check.
HTH!
Hidding the ssid doesn't bring any security
- trust me -
...
The only way is to setup a basic WPA encryption. And you will be secure as long as you change the password on regular basis (every 1 or 2 months)
Avoid WEP encryption it's just crap and doesn't bring any security.
The SSID stuff and mac address filtering are just making you think that you are secure when you are not.
30sec to 5min max to decrypt WEP encryptions, less than 5 sec for mac address and SSID stuff.
works fine on mine and I don't broadcast ssid.
>start>settings>connections>network cards
>add new
type in your SSID as the network name
fill in the rest as per your setup
ok, there is no real security on wireless, but if we are all going to use it we may as well instigate all the security options we can. if there are 2 connections for a cruiser to access and 1 is easier than the other, I know what I would do....
WEP and above do provide security, at least if you don't want any old Johnny using your network.
So, use WEP or whatever security you have.
Hiding SSID literally just hides it. However, most hacking tools easily show the SSID anyway, so don't really on this. But, if you do hide the SSID, you have to set up the connection manually, typing in the name of the SSID and WEP key.
V
most hackers tools that show ssid will decrypt wep in less than 2min.
I was just pointing it out because
1- it's to consider when you're buying an Access Point
2- If you're using it with sensible website (bank account) and such (even to check your mail - using your credit card etc ...)
fair point...
I guess it would be unthoughtful of us to give the know how without also giving the gotchas
;-)
I have got a hidden SSID and the qtek is able to find the network after typing in the name, but it ist not able to connect.
I have already checked the MAC.
It gets the right IP but after few second it scans the network for another time and so it goes on
the WIFI state is connected. but when I try to open a webpage, eg,www.google.com, it shows error: the page cannot be found. Check the name and try again. anyone knows that? how can I fix it?
Thanks.
HELP ME
Someone can help me?!
Where are you using the wifi? Is it your home network or work/hotspot?
Go to settings then the connections tab then tap the "wireless lan" icon. Tell us what you see on that screen, then click the advanced tab and tell us what is there too. Finally click "menu" then "network cards" and tell us what is there (should be a list of available networks).
The only problem I have with my wireless is that i need to have a very strong signal to be able to receive my IP address via DHCP. Once it has it then it's OK and i can wander about but I get no address when the signal is weak ( less than 50%).
Cheers

Check that you have set the connection type to "internet" - I suspect this problem occurs because you have it set to "work".

I am having the same problem , my signal is nearly 100%, the phone is set to internet, Belkin 54g,, authentication is 'open', WEP, the key was entered manually (26 digits ), do i use 802.1 access ?
mode is infrastructure, tx rate is auto, channel 11,, the mac and ip address is correct,, what is enroll ?
I have tried everything and it is obviously connected so why will it not load pages ?
Had the same problem myself with my XDA IIs. Only solution I could find was to turn disable the firewall on my router. No idea why that worked, and cant find a way to turn the firewall on without causing the problem again, but it did work!
got smilar problem here, some times even when i connected and browsed web say 2 mins. ago suddenly connection can not be established i have tried it with belkin 54g linksys and 3com routers all same couldnt find any solution and accepted it as it is

hello All and Gadget
Bought the XDA mini S from 02 yesterday and havent really been playing with it except installing programs, removing the 02 files and finding my way round the phone.
Anyway, having problem with getting WIFI, can anyone help?
At home, I use Wanadoo broadbrand wireless 'livebox' and here are the following details on the Mini S:
Wireless Lan> main tab> SSID - blank, mode - infrastruture, BSSID -blank, Tx rate - auto, channel - 0
Advanced tab > status, not connected to network, MAC - 00-09-2D-8D-66-BF, IP - 0.0.0.0
network cards tab> wireless tab - wanadoo - 2D9E available
network adaptors> network card connects to 'The internet'
Thanks in advance
Andy
Might be a stupid question but.....
Have you got any security on your wireless router? if so have you permitted the MAC code of your device to connect and obtain an IP address from your router?
Anthony.

Thanks for the prompt reply. Another stupid question is how do I find out if I have security on my wireless router and if i have security, how can i permit the mac code to do its stuff.
Thanks again.
Andy
Check out:
http://help.wanadoo.co.uk/resultDis...Configuration+Manager&resultType=5002#Goto155
Have you set up a WEP security key to prevent unauthorised access to your ADSL Connection? if not then you should; I think the 'LiveBox' has a default key which you have to enter to connect and obtain an IP address.
Not being familiar with this router, I cannot tell you exactly but I would expect you to have to permit a new MAC code under the 'associated devices' menu.
Sorry for being Vague.
Hope this helps. :roll:

First of all, thanks for the link. I am able to see all the details (technical) of my livebox on the wanadoo configuration page.
There is a WEP key set and having tried to enter as much info on the relevant places on the mini s, no luck.
The mini s does recognise the 'livebox' and connects to it then drops off. However, it doesnt pick up any info from the 'box' to complete the relevant wireless tabs on the mini s.
Dont know how I'm going to resolve this but thanks for your help so far.
Shame not to utilise the Mini S with my current wireless broadband connnection.
Cheers
Andy
Hi All
Thanks for the advice so far and after so many attempts I am still unable to configure the mini s to use the wireless connection at home.
Need a huge favour. Would anyone give up a few minutes of their time to go through the configuration on the phone with me.
Please PM me your contact number and when it is convienent for me to call you back.
Much appreciated.
Andy
Hi Andy,
the settings depend to some extent on whether you have an access point (router) or shared connection.
You need to know the network name SSID, (and whether it's hidden)
WEP, WPA/PSK key,
Whether (as previously stated) you have MAC address control enabled in your router
Whether you have DHCP enabled (for automatic IP address from router)
Whether you need to log on (enroll) to password protected shares.
In the mini-S wifi>Menu>Network Cards>Network Adapters tab you should set your network card to connect to The Internet and check that the adapter (SDIO WLAN etc.) is set to use auto IP (if you have DHCP) or pick your own IP address if you have a fixed range.
If you have Zone Alarm or another firewall (I surely hope so :wink make sure that the (mini-S) IP address is in the trusted zone
Lastly; if you seem to be connected but you can't get any web pages - just a page not found error, try killing bloody ActiveSync on the mini-S, sometimes when I'm browsing I suddenly can't access pages and that's what the problem turns out to be - when you stop active sync running in the background it all starts to work again.
This is assuming you have a router not a shared connection which may be slightly different.
Oh....and read the threads about 802.11b and g, if your router only allows 11g the mini-S doesn't connect (I'd find the threads and point you to them but I gotta get back to work soz)
HTH (feel free to contradict or put me straight guys

I had the same problem with my Linksys WRT54G before. I upgraded the firmware (dowloaded from Linksys website) of my WRT54G and the problem solved.
New to the board (Just got my Cingular 8125) Having the same problem.
I get an IP addressfrom my router, it shows I am connected on my network settings, but still can't pull up any pages. It has never worked since I got it (only 3 days though) Someone please help us.
If >Connection Manager>Settings>WiFi Settings shows you have an IP address and are connected (Advanced :Status) then check your firewall settings and try stopping ActiveSync, always seems to do the trick for me
Also check out this post, could this be your problem?

@ cozzykim
I have shut down my zone alarm and don't have firewall enabled on my linksys WRV54G. ActivesSync is also closed. Still no luck
I will try to update my ROM it is not far fetched that cingular Jerry rigged the WiFi. I hope ther is a class action suit coming soon.

I have a MDA PRO
Rom Version: 1.12.42 wwe
Radio : 1.08.00
Protocol: 42.41.P8
Ext rom: 1.12.126 WWE
What I want to do: I am trying to connect to the internet using pocket internet explorer using my wifi network at home and not GPRS.
The problem: I go to 'Settings' >>"connections" tab >> 'Network Cards'>> "wirelss" tab
It displays my wifi connection and it says "available" so I {tap and hold} and select 'connect'. It then states that it is 'connecting' but it doesnt connect and reverts back to saying that my network is "available'.
What am I doing wrong? Do I have to set up something on my pc? Any additional settings on my Universal that i should initiate?
I tried searching the forum with no luck in finding someone with the same problem. Is there a thread with a guide that can help me out. Thanks for your time.
soft reset the phone
then no need to go into settings
on today screen (main screen) touch the "G" at the top
it will ask you if you want to activate wifi
select
it should connect automatically
I have exactly the same problem with my M5000.
Can anyone help?
Are your home wireless networks protected (eg WEP or WPA) ? If so - and I would hope so - then are you using the applicable WEP/WPA settings and key when trying to connect ?
Worth also trying to set the IP address manually on the PDA, see if this helps ?
For me, the first thing to do when experiencing wireless probs is to temporarily disable any encryption and see if it works then.....and then re-enable, carefully inputting key etc.

What happened there ! :roll:
On the Blue Angel, it was simple - you just set up a new connection, enter the PSK, connect and off you go!
On the Universal, however, I'm having no joy. I've set up the WEP and PSK stuff and the PDA can connect to the network, but when I try and open IE it opens up GPRS. Also, PC Anywhere only works via USB - again, it won't connect via WiFi. I'm sure it's just a case of adjusting some settings but I don't know which ones!
Wifi Connection Problems
Hi I'm experiencing exactly the same problems trying to connect.
I have a Wanadoo Livebox and my xda exec.
I've tried with my connection both unsecured and with 128bit wep encryption using the correct wep key....I still get connecting, followed by available, repeated continuously?
I have the xda set to connect to "the internet" and the authentication to "open". Key index is 1.
Can anyone help?
Thanks

I just checked (with my Blue Angel) that the router and everything else is working and I'm happy to say it all is.
I set up the new connection on the BA from scratch - WPA-PSK enabled, nice long PSK, and I'm using TKIP. Network connects to: The Internet.
This allows me to remote up to the PC via PC Anywhere, and allows me to connect to the 'Net for free via the WiFi router.
When I duplicate the settings on the Universal, neither of the above works. What am I doing wrong?
Help!
You haven't got mac address filtering enabled on your router, and have forgotten to add your Universal's mac address to the list, have you?
Cheers,
Steve.
No, it's disabled.
hehe i had this problem tonight and was going to post up.
Has your router got MAC-control or anything on it? My SSID is not set to broadcast so I put the settings in manually.
I deleted the settings, and put them in manually again a few times, making sure I had the encryption stuff set correctly.
Eventually it connected and now seems to be working fine.

Ad Hoc?
Ok, I've tried every possible combination possible and nothing is helping. So my next question to get around this problem>>>>>>>>>>>>>>>>>>>>>>>>>
Can I use my pc as a ad-hoc and us it as my gateway for my Universal?
I have a pc in the office down the hall with the actually wireless router, I have a pc in my room that is accessing the wireless router from the office.
Please let 'US' know if you have tried ad hoc or if you find the right settings to connect to the main wireless router.
Thank you
I am on my wifi network typing this, and my settings show 802.1x network access control not having a tick and network adapter connected to Work......on my iPaq hx4700 before, I used these same settings as they seemed to work well, although it ran WM2003SE not WM5.....
All this said, however, but I was lucky in that my MDA Pro connected to my wifi network at the first attempt - except not with as strong a signal as the iPaq had.....
Wifi Settings
Can anyone who has connected okay, let us have their full settings, so that we can try them?
Is your Router set 802.11g only?
You need to set the router to accept 802.11b and 802.11g.
If your router will only output at 54g, you could try the hack to switch the universal to 54g. I am yet to try this so I don't know if it works.
My MDA Pro connected straight out of the box once I set the ssid and encryption.
Hope this helps

I've been on the phone talking to 3rd line support at Orange.
Basically, the guy is totally flummoxed!
After trying to talk me through the setup from memory, it seems as though a whole menu of WiFi settings has disappeared from the phone - specifically, the ones that we need! This being the case, he's going to get hold of an M5000 tomorrow and will then bell me back so we can go through the whole process together, both of us using an M5000.
One thought that did occur to me was this: I've only just (like, 3 days ago!) upgraded to the M5000 and I've taken on some kind of free Internet access scheme with my tariff. Could it be that the settings for that (that are sent by Orange in a data SMS) have knackered the WiFi setup?
I'm considering a hard reset with a soft reset before the .CAB files install but will at least wait until tomorrow.
I'll keep you all posted....
hi guys, any help you can give is realy apreciated,
ive never used wifi before on my exec or in a home network so treat me as a beginer. ive got a pci wifi network card and i am trying to set it up so i can use my mda pro when i am at home. my computer is currently connected to my housemates wired network which is a simple set up

like i said nothing fancy, i installed the network card which went fine and bridged my network connections together as advised by my large local computer retailer. my computer asked me to provide a name and network key so i did. my pc is now connected to my mda pro.
and in the wifi it displays

i cant get any internet based app to work and i am asumeing its due to the settings, any help is gonna be soooo apreciated
i dont want to subscribe to wifi in the city if i cant get it working in my own home lol
any one think this might be a network problem ?
ive posted a few questions on network forums but no reply yet
i am lost
:?
From the info that you have given, it looks like your universal is getting an incorrect ip address. What you need to do is check what your desktop ip address and gateway is. Then give your universal and ip in the same range as the desktop ip and also add the gateway to your device. It should wotk this way !
The best option would be to get a wireless access point instead of the wireless network card and set things up like this.
....bb modem......
...........|..............
........router........
..../......|......\.............
my...access......his......
pc......point.......pc......
The wireless access point plugges directly into the router rather than connecting through your PC.
If you don't fancy the above setup then you could use internet connection sharing. You'll need to remove the bridge between your network cards and ensure that the router,your PC and friends PC's isn't using 192.168.0.x IP addresses.
Then you can select ICS (tick the allow other computers to access internet...) on your network card's (one to the router) advanced properties and select your wireless NIC as your home network connection.
I hope this isn't too heavy I've resisted the temptation to start talking about subnets, NAT, DHCP and all the other networking terms.
Hi Guys & Gals,
I have a brand new HTC Touch Diamond 2, on O2 network - this is an untouched device, all i have done is booted it up and sync'd it with my PC,
I have tried to connect the device to to wireless networks now with no luck.
1. My home connection - security enabled WPA-PSK password protected, The phone can see the network, i type in my network key - i also checked the password on my router setup. The little spinning circle comes up and try's to connect with no luck. It will then keep trying for as long as the wireless is on
2. Home connection again with no encription - again the same thing
3. Work connection WEP secured, type in the key, same thing again.
Has anyone encountered these sorts of problems before in the past - if so how do i fix it so i can connect wirelessly.
Cheers Guys
JdeRonde
Doubt if this is an issue with the phone more likely to be a setup of the wireless.
What router do you use?
Do you have MAC Filtering enabled?
Do you use your router as a DHCP server?
Are there any error messages displayed on the phone?
When it doesnt connect and you tap the notification area (top bar to the right of START) do you have any messages there?

I too had problems with WIFI. My home work network was visible but it would immediately drop or not be able to connect. A few days later it started working flawlessly and I have no idea what changed.
I am sure you have tried a soft reset but just in case...
Tony
I have a NetGear DG(Some Number) v4 ADSL wireless router, which i have set up and works for all of my other devices (ie. Laptops, PS3). With a simple encription key.
I get no messages etc, all it sais is that its 'not connected' and there are no new notificatons
It then persists in trying to connect again and again, when it cant connect for a while, it then comes up with 'new network connections found' in the notificatins area.
I have switched the power mode to best performance with no luck.
I have tried on 2 different networks now. including with all encription off. WEP and WPA-PSK - This is driving me nutz cuz i love the phone, i just want to use it to browse the web without paying out the nose for it.
DHCP server is dynamic from my ISP.
I have contacted HTC now about the issue, but im going to feel so stupid if it turns out to be somthing simple like a setting on the phone somewhere.
But thanks for the reply
Have you checked you arn't using MAC filtering?
Log-in to your router and check under Wireless settings > Wireless Station Access List.
While you are on your wireless setting page check what Encryption your using for WPA-PSK? TKIP? (The wrong encryption chosen will cause you not to be able to connect)
Ok maybe telling you how to suck eggs but on your phone:
Settings > Communication > Wifi
Select Advanced at the bottom right.
Select Change Network
Click Add new...
Type in the name of your network (The SSID also found under wireless settings, Case sensitive)
Select Connects to: The Internet
Leave the other two boxes unticked.
Click next.
Select the correct Authentication - WPA-PSK is different to WPA2-PSK. You will probably be using WPA-PSK.
Select the correct Encryption (Propably TKIP)
And type in your Network Key
Click Next and Finish.
How does this fair and what are the results of checking info on wireless setting page?
Im at work at the moment trying to connect to the WEP connection,
This connection most deffinatly does not have mac filtering on it, just asked the network tech.
Okies.....
Changed the network key to.... Shared key and it works
so i am guessing that it must be somthing to do with my setup at home..
Cheers guys
Cool.
Just match up the Authentication / Encryption / SSID and Network Key from the router to your phone setup and you should be fine.
HTC TD2 Wifi issues
Hi
There's some discussion around the web about this problem of encrypted wifi connectivity: a few things to note
1] the TD2 is _very_ sensitive to the power settings applied to the wifi chipset.
The default power saving settings are only likely to work if all other on-board devices - bluetooth, HSDPA, GPS [and maybe even the screen] are either off or in low power mode: the general recommendation seems to be that one adjusts the wifi device power to be "best performance" if one wants to guarantee connections.
2] several people have reported that both the wifi device [card] and the settings for the particular wifi lan [SSID] to which you are attempting to connect should both be configured for "Work" rather than "The Internet".
3] these secured/encrypted connection failures are not about the WiFi access point or router: I've personally tested with several different makes and models of Router and Access Point [3com, Cisco, Enterasys, Netgear, DLink, Belkin etc] - both on my own and on client networks where I have complete control of security, and have also methodically tested every single combination of TD2 setting for WEP and all variants of WPA. In each case my TD2 has failed to make a valid encrypted connection.
The same device will happily connect to "open" unencrypted access points and routers.
Other models of HTC device, such as the Tytyn II and Touch Pro work fine on the same access points and routers: so we can be pretty sure that this is specifically a TD2 issue.
Conversations with HTC's European Tech Support on this issue have not been helpful to date, but they HAVE pushed the issue further up the line, so there's a chance that we'll see a resolution.
