   is the 2nd set better or the first

   not surI’m e how you are able to make manual entries under. My iPhone’s DCHP settings prohibit me from making manual entries as they must be automatically acquired from the router itself. That is… the router issues the IP and DNS info once the WEP password has been input.

   Hey, thanks for this tip. I have this problem with my wireless router (Linksys WRT160N) at home where a page in Safari would load only half way or not at all. Twinkle wouldn’t connect either. I’ll try this out and see what happens.

   I used the opendns service along with those DNS id’s and it appears to be working very well now. Thanks!

   Just a general tip:

   The two IPs you mentioned above: 208.67.222.222, 208.67.220.220
   come from a service called OpenDNS. I would highly recommend using these at home and go to opendns.com for more info! It’s a free service and it is absolutely amazing. You can choose different options and it can block spam, etc.

   Adam on July 16th, 2008 1:07 am:

   Thanks for the info. I saw those IPs mentioned several other places. I’m not sure where Doug found the first set, but the second set is what I had used.

   hi on January 26th, 2009 5:05 pm:

   does that work for an IP? Does it automatically save when you enter it once or do you need to enter it every time you access it.
7. rog on July 16th, 2008 2:48 am:
   

   Actually, the easiest fix for Linksys and most of the wifi AP’s is to modify the DNS entry in the iPhone to match the “Router” (default Gateway) IP Address. This is a minor DNS bug in the IP stack in the iPhone’s Mac OS. You don’t need to do this for all Linksys models. Only if you experience connection problems with the emails or Safari after you got the valid DHCP address from the AP. If you don’t have any problem browsing, you don’t need to fix it with this workaround.

   Cheers

   I have a iPhone 8gig purchased 18 months ago. I am in Indi. Everything was fine until i upgraded it to Firmware 2.0 now my iPhone doesn’t catch any Wifi signal and the battery doesn’t last for more than 8 hours ( Idle time ) if i use it, i bet only 3 hours would be the backup. I have tried a million restores and upgrades but no luck. I have noticed that there are many who has this problem. They are lucky bcos most of them got it replaced with Apple and few got brand new ones . As i live in India, no apple stores who repair 1 st generation iPhones. Recently iPhone 3g Was launched in India so, they repair only 3g. I am sure that my Wifi radio is fired

   Note: i also edited com.apple.wifi.plist but no luck
   you can ping me on Raghav_vicky23@yahoo.co.in

   Thanks in advance

   I have a question sorta related:
   I am using a airport extreme and ever week I have to reset it because I loose the ability to SSH in.
   All I have to do is unplug the airport and plug it back in it sets itself.
   I have been on with Apple support for HOURS and they sent me another airport but its the same outcome.
   I have everything plugged into my UPS unit so I dont think its related to power.
   I never loose WiFi for my network but do loose the capability to print via the airport.
   The lose of printing capabilities is what alerts me that I need to unplug my station again and reset it, of course the lack of SSH also reveal this same thing.
   Anyone else hear of this or have this happen to them???
   I would really like to get tot he bottom of this and finally get this addressed…

   Thanks

    Is this specific to the US or is it a “generic” thing that will work here in Canada also?

    OpenDNS has been around for a bit and has always worked for me when I’ve had network/DNS/can’t connect to the internet but show an iP address on my machines at home. Glad to see it finally mentioned here. Cheers!

    Hello Douglas/everyone,
    I need a bit of your help…

    I can’t connect mine to any hot spots wifi.
    No Router & DNS show up, just the IP Address & Subnet Mask shown only. Any idea what’s wrong?
    But somehow while at home I had no problem connecting to my Airport extreme BS.

    Mine is a 1st gen 1.1.4 jailbroken iphone.

    Let me repeat what has been started:

    “There was some problem with the DNS information and that you can manually change it and it would fix the problem. So here are a couple of Free Public DNS options and the instructions on how to fix it:

    1. Connect to the WiFi that is giving you the problem. You must be able to connect to it. If you can not connect then this won’t work for your problem.

    2. In your settings select WiFi and then tap the blue arrow next to the WiFi name you are connected to.

    3. Erase the DNS info and add the following exactly like this: 67.138.54.100, 207.225.209.66

    Note: In case the first two don’t work try this: 208.67.222.222, 208.67.220.220

    I also tried this and already working and it didn’t seem to effect anything. It still works fine and wasn’t any slower or faster. So give this a try and let me know how this works for you.”

    Believe me, I have searched everywhere for a solution for the Iphone wifi problems, Im convinced it is a software issue, theres too much people having this problem, in many cases it begun with software update or a iphone restore after without it everything was working OK. And about the solution proposed in this article let me tell you this is te only advice that worked for me, I have only been testing it for about 20 minutes, but I was able to connect to wifi all the atempts. My question is, why couldnt apple realease a memo saying whats the solution for this problem, I couldnt even register to the apple website to post a comment on this. I tried everything before, even claiming warranty without success (excesive burocracy and greed from tech representatives) I hope once for all this solves all my Iphone Wifi’s problems. Thank you indeed.

    Hi,

    i’m using iphone 3G 16gb. previously i’m using ver 2.1and turbosim. i’m having problem with the wifi. This happened when my wifi was abruptly disconnect while i was downloading an application from apple store. it leave a hollow application button. since then the wifi can only detect the network but unable to connect to any wifi network either the open network or secured wep or wpa.

    With the latest release of the jailbreak of 2.2 i managed to jailbreak my i phone, hoping the wifi will fix itself but to no avail. The yellowsn0w is install using the iphone pc suite(i was told). I obviously paid for this service. The guy who does this told me he can’t fix the wifi too.

    is the wifi fix in yr website is only for 2g iphone? I would really appreciate if you have a solution for this problem or at least lead me to a solution.

    I’m living in abu dhabi and bought the phone here from a third party shop.

    Hello All:

    I have had this problem for three months. I tried everything listed on this page-still nothing. Changed routers-still didn’t work. Change from WEP,WPA,WPA2,back and forth, etc.-still nothing. Went to the Apple store-they tested it-said “it’s fine, it connects to our network open and with WPA, WEP, etc. We restored the software.” I went home-SAME PROBLEM. I knew it was the device the whole time because everybody else I know that has the same device, software, etc.-WORKS. So I went back to Apple-told them the whole story-again. They tried to turn me away-AGAIN. So…I read the “Genius” the riot act in the nicest way possible…and guess what-he warranty exchanged the device and IT WORKS FLAWLESSLY NOW. ***Apple has become harder and harder to deal with as time goes on, I am a data consultant in the wireless industry, and explained the issues to the Apple rep in terms he understood…but it didn’t matter. The only way I could get him to warranty the device was through verbal force…so go to Apple and use your words!

    I hv an official unlocked 3G for almost 2months now. Running Firmware 2.2 with jailbreak. However, the WiFi + Bluetooth has stopped working since a week ago. I can’t detect any SSID on WiFi listing even when I use WiFiFoFum & WiFiTrak to scan at home and at places with known WiFi service.

    I’ve tried resetting network and even performed factory restore with no success. Also tried reading up on several forum/support/discussion and discovered this problem is quite common but all does not provide any solution.

    Everything else works perfectly and phone reception is usually optimum level. An inspection on the camera + headphone rings and chrome bazel, which Apple claim are the antennas, are perfectly intact as the phone has never been dropped or subjected to any physical abuse.

    Have I missed out anything or can anyone please provide a solution?

    Thank you for the great information.

    I thought my wifi was dead on my 2G running 3.1, but after I entered in the second set of numbers: 208.67.222.222, 208.67.220.220 Everything worked great for about 5 minutes. Then stopped working. If I use the first set of numbers: 67.138.54.100, 207.225.209.66 I get a solid wifi connection, stays on for a long time, but no with connection to the internet.

    Should the iPhone have the sam IP as my AirPort Extreme?

    This sucks, because everything was working perfectly and one night wifi just stopped working defaulting to EDGE.

    Hi guys. I used to have the 2g iPhone and I had excellent wifi connection at home. Just recently I bought the iPhone 3gs and upgraded to firmware 3.1 Now, however, my iPhone rarely detects a wifi connection at my home (even when it does connect, it is for a minute or so and it is bad and then it goes back to my AT&T 3g network). Can anyone please help me out here and what I can do to fix this… It would mean so much. Thank you.
