WiFi connected,but can't browse ? * Possible Solution*

[Guest ZanderZa]

Hi guys,

I have managed to get my WiFi working the way that it is supposed to work.

After struggling for hours and days,i finally came to the conclusion that the omnia has

some kind of problem with protected WiFi networks.I therefore disabled the security features on my router

and it instantly allowed my omnia to browse the internet through my WiFi.However leaving your router unsecured is risky...

So i then enabled wireless access control on my router and added my omnia's MAC address to the list of allowed devices.

What this means is that no device with a MAC address other than the ones specified in my router setup will be able to join my WiFi network.I also set my network to hidden (Disable broadcasting of SSID),so now my omnia is connected,able to browse the net,and my WiFi is moderately secure.

So here are the steps you need to take:

1. ROUTER SETUP

1.1. Disable security on your router e.g. WEP,WPA-PSK,WPA-802.1x etc.

1.2. Disable SSID broadcasting of your WiFi in your router. (To make it hidden/more secure)

1.3. Enable wireless access control,and add all devices (by MAC address) you want to allow access to your WiFi network.

2.OMNIA SETUP

2.1. Settings > Connections > Wi-Fi

2.2. Add New...

2.3. Specify your Wi-Fi nework name & choose "Connects to: The Internet"

2.4. Select "This is a hidden network"

2.5. Next

2.6. "Authentication : OPEN"

2.7. "Data encryption: Disabled"

2.8. Next & Finish

2.9. > Network Adapters

2.9.1 Set "My network card connects to : The Internet"

Now your omnia should be able to browse the internet through Wi-Fi.

Good luck . :(

No problem at all making a WPA2 or WEP protected connection with my Linksys WRT600N router...

MAC filtering is not as secure as people think, hiding and decent encription is the best option.

I agree that encryption is more secure,but this tread is not about the best possible security for your home Wi-Fi.This thread is aimed at providing a possible solution to the internet browsing dilemma which a lot of users are experiencing.If this thread was aimed at best security...then i would have agreed that encryption is the best option.However some omnia's just don't want to work with encryption.

Therefore if anyone is experiencing this problem,they can use the method i explained at the cost of some security,like i have explained MAC filtering should be enabled & broadcasting of SSID (Hide) should be disabled,which would of course hide you network.

So to come to a point...yes it is not the most secure setup,but it fixes the problem and still offers relatively good protection.

I can also connect to my router with both WPA & WEP enabled,however i am then unable to browse the internet on my device,using both IE6 and Opera,if you are able to both connect to your router and browse the net on your mobile,then you are one of the lucky one's.I dont know why some omnia's work and others dont,but if you'll kindly take a look at this thread ( http://www.modaco.com/content/i9x0-omnia-h...rowse-internet/ ) its becomes clear that there is some kind of problem.

Yup, I'm not having any problems at all. Not only can I use Opera and PIE without issues, I can mount network shares via Resco Explorer from my PC and browse them, transfer files, Stream video from my Orb server -- anything that requires a network connection. No problems at all.

I'm sorry you and others are having problems, and I wish I knew some magic to help. I did initially have problems connecting, and just posted a thread about it -- my problem was multiple APs in my wireless network with the same SID (a completely proper and normal thing to do). The Omnia doesn't like that. Easily fixed by just creating two wireless networks with different SIDs. Annoying because both networks then need to be set up on everything using wireless, but a very functional workaround.

Oh, one more thing that might be helpful: My linksys routers have an "auto" setting for authentication which is the default (other choices are OPEN and SHARED KEY). The Omnia didn't like this either, and I could never connect with encryption with the AP set to "Auto". I could connect without encryption in that mode.

Explicity setting the authentication mode on both the AP and the Omnia (they have to match, of course) solved that problem, and I was able to connect securely with WPA2 (and WEP).

You don't want to use SHARED KEY anyway -- paradoxically, it is actually less secure than OPEN authentication. Anyway, if your router has an AUTO setting for authentication, try setting it, and your Omnia explicitly to OPEN, turn on encryption, and see if that helps.

(what's this authentication stuff all about anyway? The thumbnail answer: A Wifi connection goes through two steps to make a connection -- association, and establishing a link. After association, your Omnia will report it is "connected", even though it may not be authorized by the AP yet to transfer data. Next, there is a protocol for establishing the network connection. With an OPEN setup, this is one-way -- the client requests to connect, and the AP sets it up and basically says "OK". In the case of a SHARED KEY authentication, the AP encrypts a challenge phrase with the WEP or WPA key, sends it to the client, the client which has the same key [shared] decrypts it and sends it back plaintext. If it matches what was sent, the AP establishes a connection. The problem with the SHARED KEY approach is that both the encrypted and plaintext versions of the challenge phrase are transmitted, giving a hacker a substantial leg up on cracking your encryption key. OPEN authentication allows anyone to connect to your wireless network [absent other security measures like MAC addr filtering], but if your using secure data transmission with WEP or WPA/WPA2, it doesn't matter -- they can't do anything.

I believe that what's happening above is that the Omnia has a bug and is not handling the connection authentication request properly. When set to OPEN on the Omnia and "AUTO" on the AP the AP thinks it should be doing a SHARED KEY challenge phrase handshake, encrypts it and sends it, and the Omnia being in OPEN authentication mode ignores it and never sends back the decrypted plaintext. So, the AP never gets a response to the challenge, and never establishes a connection. Because the Omnia is associated with the AP, it looks like it's connected, but data traffic is being ignored by the AP. Explicitly setting both to the same authentication method solves the problem.)

I have had the same problem, open authentication (WEP and no encryption) works but WAP and WAP2 shows connected but with no web services, ie does not authenticate. I called Verizon who tansferred me to Samsung, went through 3 levels of support. The result was that there is a known problem with the phone in its ability to authenticate with some access points or wireless routers (apparently mine being one, the WAP54G by Linksys).

Samsung will be rolling out an update and a fix MAY be included in that update, but that is not known until the update is actually rolled out.
