Hi,
I have a DSL G604T WiFi router that works fine - my laptop and other laptops connect fine via WiFi.

The problem is my iPhone consistently connects and reconnects without establishing a clean connection. I see in the WiFi Netwroks screen that the 'tick' to show that WiFi is connected on my phone goes on and off and 2 second intervals.

I can connect to other WiFi networks without difficulty - and other laptops can connect to my WiFi, so I am at a loss on how to fix this.

I have googled a bit but no-one seems to have a solution.

I open this problem then to the NZ IT expert cloud-mind :)

thanks in advance
cheers

Have you done yesterday's update to iOS 4.3? There were bugs with iOS 4.2.1 which have hopefully been fixed in 4.3.

Run Apple Software Update first to make sure iTunes is up to date? (10.2)

Do you have an iPhone 3G? If so, you won't see the update in iTunes as iOS 4.3 doesn't support the 3G.

Have you reset the network settings on the iPhone?

Reset your router to 'g' from 'n'. Usually works.

HTH.

The DSL-G604T doesn't support N, so don't go looking for it.

If it did exist it would be under the DSL-G604T menu: Advanced > Wireless Performance and under Mode.

Go to that menu anyway, and if it's not selected already, select "G Only", click Apply.

Then, go to Tools > System and select Save and Reboot.

Wait until rebooted, revisit the menu listed above and check the setting stuck. The retest from your iPhone.

If there is still a problem, reset your iPhone network settings.

From the iPhone Home Screen, click on "Settings". Go > General > scroll to the bottom >"Reset", then "Reset Network Settings". After accepting the warning > Go Settings -> Wifi, see if you can see your Wifi network, attempt to connect.

The Apple support link for Reset Network Settings is here: http://support.apple.com/kb/ts1398

See what happens.

I had no end of trouble with my (Telecom supplied) G604T. Wired connections were mostly fine, but wireless connections were very problematic, to both my laptop and phone (a Nokia). This was even true a couple of feet away in the same room.

Replaced the router with a Belkin that I got a good deal on some months ago and all is now fine. Wireless is rock-solid to all devices, and I can easily stream video from the upstairs study to the downstairs living room.

Try a different router - that model is v. old and, in my experience, crappy.

@ArtooDetoo - from memory his model is wireless B/G only, so he can't flick it to n and back again.

You've had a couple of responses I see, so maybe your question has been answered. I wasn't aware that the router you have has no 'n' functonality, so I'm sorry I put you on the wrong track.

I know from experience that having a mx of 'g' and 'n' devices in my own net has proved unsatisfactory in the past, hence my original reply.

Good luck with finding a solution that works for you.

Cheers,

One reliable way to mix G and N without problems is to go with a dual-mode dual-radio router. Set up two concurrent SSIDs, run the N connections at 5GHz and the G connections at 2.4GHz, and they won't interfere with each other.

I run my video streaming over N at 5GHz, and reserve 2.4GHz for laptop web surfing (using N) and occasional use with my phone (only G capable), which seems to work fine.

Once you've set the DSL-G604T mode to "G Only" under Wireless Performance, saved and rebooted. And once you've reset your iPhone network settings, if things still arn't working check:

Dlink admin menu > Advanced > Wireless Management > look at Mac address filtering. If it's on, turn it off.

Dlink admin menu > Advanced > Wireless Performance > look at Antenna transmit power. Check it is max.

Dlink admin menu > Home > Wireless > If not using WPA security, check the WPA button and under 'PSK String String' enter the secret password all devices connecting on Wifi must know.
Then, Admin > Save & Reboot. Check to be sure the setting stuck. Go key the secret password into your iPhone. Connect.

I recommend the last point above, even if you've done it before.

hi all,
sorry - was offline over the weekend....
thanks for all the help.... really appreciate this.

however, after doing all the suggestions above (bar buying a belkin :).... its now G only, full antenna etc....

it was set to WPA, but reset it to this and put my password as the PSK String - saved and rebooted (it did not at this stage to off)....

but now the phone sees the router it fails to connect after submitting the password... :(
