Question about Apple iPhone Smartphone

IPhone not seeing DNS or Router on certain WiFi systems.

My iPhone 3G v.2.2 is unable to connect to certain WiFi networks even though it sees the net and I enter valid PW. My co-worker is able to connect with same hardware/software. I notice that his phone sees the DNS and router numbers and mine doesn't. Presume this is the problem.

Fix =restore ispw 3G firmware that is earlier your present one, from someone like iclarified. try a few untill the wifi connects online.
you can search net to see how to restore to earlier firmware using itunes.
when wifi, hopefully works, update to latest firmware .
I assume your phone is a import, australia, hong kong? not from your current country.
even if it does nt work no harm should be done.
good luck

How to Fix iPhone 6/6 Plus Show WiFi Problems


"Anyone experiencing really slow WiFi on their new iPhone 6 Plus? Mine is super slow. When I switch off WiFi, LTE works perfectly and very snappy. I didn't have any issues with my 5s and not having issues with my iPad Air. I doubt it's an iOS 8 issue because the 5s and iPad Air are running iOS 8. WiFi also works fine on my 13" MacBook Pro Retina. It's not a router issue. Any ideas??" asked by Mikef91 on the Apple's office discussions.

As one of the leading wholesale cell phone parts supplier online, DBXStore find some solution for you to fix the show wifi problem on your iphone 6/ 6 plus.
Greyed-out, slow or no Wi-Fi signal at all are among the top three biggest Wi-Fi headaches. Even though the iPhone 6 and iPhone 6 Plus came with iOS 8, Wi-Fi problems are still not completely avoidable. Before searching for solutions to Wi-Fi related problems, always update your device to the newest version of iOS. If that doesn't work, then it is time to dig deeper.


1. Reset Network Settings

Settings > General > Reset > Reset Network Settings.
This is a solution suggested by Apple Service. Resetting your network settings including Bluetooth pairing records, Wi-Fi passwords, VPNs, and APN settings; which flushes cache and clears DHCP settings and other networking related information.
2. Disable Wifi Network Services
Settings > Privacy > Location Services > System Services.

This only relates to your location being used for network and not the Wi-Fi itself.

3. Switch DNS To Google

Often times, if your ISPs DNS servers are having problems, you can switch to Google DNS by going to Settings > Wi-Fi then tap the "i" icon next to your router, scroll down to DNS and tap the numbers, then enter "8.8.8.8". Restart your device and check if it works.

4. Change The Routers Broadcasting Band

Change the routers Wi-Fi broadcast from an N network to a G network, or from 2.4GHz to 5GHz - this depends on your individual router hardware.

5. Factory Reset

Settings > General > Reset > Erase all Content and Settings > Erase iPhone.

Last but not least, restore your iPhone and set it up as a new device.

Other tricks like placing the iPhone 6/6 Plus in a refrigerator, freezer it for 15 minutes, or the opposite using a hair dryer to heat up the device might also be of help.

However, if all these software related tricks don't help, it could possibly be a hardware problem with the Wi-Fi antenna. Then the only fix is to replace your antenna with a new Wi-Fi antenna replacement. Here are links to the parts and tutorial guides' for reference.

How to connect an iPhone to the Internet


Connecting your iPhone to the internet is an easy process. You just simply use any application on your iPhone which uses internet service.

Your iPhone can either use WiFi or Cellular for internet access.

- A WiFi network is simply a wireless network. You can find them at coffee shops, libraries or even at your house if you a router setup for wireless access.

- Cellular data networks allow Internet connectivity over the cellular network. Check your carrier's network coverage in your area for availability.

When you use an application on your iPhone that requires internet service it will either connect to the last WiFi network used, or if that network is not available it will list all available networks in range. You can simply tap on the network you wish to join and it will connect. If the network requires a password it will show a lock icon. If no Wifi networks are available your iPhone will connect over the cellular data network and fees may apply.


To see all the Wi-Fi networks in range, from the Home screen choose Settings > Wi-Fi. Tap a network to join it.

When i select my Linksys WiFi connection on my Iphone I still has the "E" edge symbol on my Status bar even though wifi is selected.


You can tell iPhone is connected to the Internet over a cellular data network if you see ht1695_utms_onb.png,ht1695_3b.jpg or ht1695_gprs_onb.png in the status bar at the top of the screen.

Do you have problems connecting to any other wireless network with your iPhone?

Have you tried using the forget this network option on your iPhone for your wireless network followed by trying to connect to the network again, and/or using the reset network settings option on your iPhone which erases all previously saved wi-fi connections that you have successfully connected to with your iPhone?
Let me know....

Internet on iphone 3g??


Simply go to Settings > Wifi. If Wifi is off, turn it on. You'll see a list of available networks when you're in a hotspot. You can also have iphone tell you when you're near hotspots by turning on "Ask to Join Networks." You won't be able to use the internet when you're not in a wifi hotspot.

IPhone Wi-Fi only works when it's really close to my home's router...


Sounds like there is a problem with the WiFi card in your phone, take it back to an Apple store, all Apple stores have a WiFi open network so you can show a Mac Specialist the problem, my thinking is if it doesn't connect at home then it wont connect to there network. If your phone doesn't work in the store ask to speak to the manager or assistant manager, be persistent and insistent if your iPhone is not hacked they will change it but you have to fight your corner.

No data over WPA2 WiFi


A few things to try if havent all ready. Make sure your other wifi devices can connect to internet in this network. Toggle airplane mode 15 seconds. go to Settings -> General -> Reset -> Reset All Settings. In wifi settings join other network and manually enter SSID and wpa2 password, rather than trying to connect automatically. Turn ask to join networks off if you have to. Make sure the Wifi symbol is next to AT&T on top of phone. Open safari. If you are able to connect to router but not internet in safari. Check your Dns settings on iphone, if iphone is not resolving dns, make sure your router is configured properly.
