iPhone will not connect to Linksys WAG54G Wi-Fi

Couple things that I see cause this





1. Outdated Router firmware, So updating it to latest software will help. Contact Linksys for Firmware assistance.

2. Changing WiFi Security. If your WiFi password is 5 to 10 characters, Switch it to WEP128 bit with a 13 character password. or WPA/WPA2 with 8 character or longer password.

Also ensure that if you are using MAC address filtering, that you add your iPhone Wireless Address into the router.

It can be found by going to Settings - General - About - Wireless Address

I have a WRT54GL that I have connected to without difficulty. It is set up as a WPA-PSK with a lengthy key. I would have to double check the firmware on it. It may not be "the most recent", but it is fairly recent.

Are you seeing the SSID? If not, go into the setup for the router and turn it on so that you can see it and connect.

Nothing on the phone can be changed to make it work unless a Software update was released to fix whatever was preventing a proper connection.



Can you connect to any WiFi networks at all? If so then it does isolate it to something with the router.



Based on what you said. You go to Settings - WiFi - You see your network, Tap on it. And Unable to Join?

So you never get a check-mark by the network name?

If you do actually get a check-mark next to your network, tap on the Blue circle. Would be interesting to see what the IP address started with.



Based on what you said when you disabled security, Did the iPhone no longer show a Padlock next to the WiFi network?


Also try changing the SSID sometimes that oddly works.

I would suggest flashing the router with the latest firmware again and then resetting everything from the factory settings. There are some occasions which I have encountered where the router would just get cantankerous, usually after a power outage. Flashing it again seemed to take care of it many times.

Try this...
Go to airplane mode.
Then go to wifi and turn wifi back on.

Sometimes if a connection for mail gets started before wifi comes up it seems to block wifi. A push account started on Edge might do this.

All the other words of wisdom I have seen:
Use channel 1 thru 6 on the router. (lower is better).
Lock the router to 810.11G.

Kiwi, did you unplug the routers power and reconnect?

Hi Kiwi,
I have the same problem as you. I got my router from snap. It's the same model number and it has been flashed to the latest firmware (my ISP confirmed that). I can connect to any other router I find and know the password for but I cannot connect to my own! There are three other computers that are connecting wirelessly to the router as well without any problems.

Fixed!!

You need to upgrade your router firmware to the latest Auzzie version 1.00.46 while in NZ we only get 1.00.23.
The upgraded firmware adds the AES algorithym which you need in order to connect the iPhone.

YAY!
