Networking & wireless forum: issue with iPhone 3G connecting with D-Link DIR-655

I've gone through about every troubleshooting step I can think of at this point, and guess that the iPhone may just not work with the DIR-655 for some reason. I've tried shutting off wireless security completely, using WEP only, using WPA only (instead of mixed WPA and WPA2), and although the iPhones actually say they're connected (shows wi-fi bars in upper left corner), when I attempt to connect to iTunes, I still get the message that I need to be connected to a Wi-Fi in order to access iTunes. I don't know what the issue is with the DIR-655, but have successfully connected the same iPhone to every other Wi-Fi router (about 5 or 6) that I've come accross, each with varying wireless security modes. If anyone else has any suggestions, I'd love to hear them.

The issue took me a bit to find out, but I finally got it. The iPhone wasn't reading the DNS server information correctly. It was assigning the DNS the same address as the router's IP address. I still haven't figured that out, but after changing it to the router's actual DNS servers, the iPhone is getting Wi-Fi working just fine.

I really don't believe that the issue has anything to do with the router at all. I've successfully been able to log into the wireless with at least seven laptops without issue. For some reason, though, the iPhone just doesn't see the correct DNS server. Instead, it sets the DNS to the exact IP as the router itself. If laptops connect fine, I don't see how it could be an issue with the router. It could be something simple in the settings of the router, but I have such a unique setup on the router, that I hesitate so simply reset it and test that (since it would mean at least 1/2 hour or more to set it back up after the reset). It was simple enough to go into the iPhone and set the DNS permanently.

I had the same problem with the DIR-655. dlink.com.au [on 19 Sept 2008] advised me that the problem will be resolved with a firmware upgrade for the router which they plan to publish on their website within the next weeks. They confirmed that they have successfully tested two iPhones similtenously connected to the router. Give the other unspecified improvements to be rolled out with the upgrade I guess they want to make sure that the further testing they are probably undertaking guarantees a positive outcome for users. I guess compatibility issues between unrelated user products is something we learn to live with. Anyway the good news is that it will be fixed.

Cheers Ant..

PS I am a user just like you and have no connection with iPhone or dlink.

I solved my iPhone 3G wireless problem by updating the DIH-655 firmware to the latest version. Thanks for the tip!

I am using wpa2. I have a dsktop with linux....another with windoze..two laptops one with xp and one with OSX! Everybody connects and prints happily. My son and I both have iphones. He and I both connect to network. I have even printed from mine. Here is a suggetsion....its stupid and I cant explain WHY it works. I hooked up my old 615 router...let it run for a day. Then rehooked the 655. Everything worked.(I had been having some difficlties when I first got the 655. But since that "fix"..everything has been wunnerful.

One you create a WPA Personal secured zone, the iPhone will be able to connect in a secured fashion to that zone. I think the open network is conflicting with the security settings in the iPhone.
You can do that under "Advanced >> Guest Zone"
I enable zones to talk to each other, left the default "Auto" and cipher TKIP and AES
