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 can I extend my home internet network?


Yes you can connect the LAN ports with a network cable from your 3G router to one of your old router LAN ports
Before connecting the 2nd router:
Check it does not have a conflicting IP.
Check it is in the same subnet
ie if 3G router is 192.168.0.1
Set old router to 192.168.0.10
subnet mask 255.255.255.0
gateway is 192.168.0.1
DNS 192.168.0.1

Set DHCP off on 2nd router.
Set WIFI to Same SSID, same password and authentication
ensure it is on a different channel though.(not automatic on either)

Finally just to make sure remove any WAN settings from your router, any old ADSL config etc so that it doesnt think it is a gateway.

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.

Dns error eventhough wifi connection is excellent


You will need to set your wireless connection to a static IP adress.

Try 192.168.1.67 (if linksys router, if others try 0 rather than 1) The last three digits on this line can be anywhere from 2 to 255. They must not match any other device on the network, including the router.
subnet mask 255.255.255.0
default gateway needs to be the routers IP. 192.168.1.1 (if linksys router. If others try 192.168.0.1, or 192.168.1.2)
and the DNS also needs to be the same as the routers IP. See above. ^

Goodluck!

When trying to connect my iphone 3g to the wireless router i am getting the error message unable to join the network USR5461 even though I am using the correct password. what do i need to do to correct...


I wonder if your router is set to perform MAC address filtering. If so, you have to either find the MAC address of the iPhone's wireless card and add it to your router's appropriate list, or set your router to not filter by MAC addresses.
Just my 2 cents... Carlos

I want to connect my Iphone to my wireless network..can I do that When I try to go on line with my Iphone it sees my local network but will not accept the password I have a wrt160n broadband cisco router


Hi there,

First of all you will have to configure your router to accept the iPhone. To do this you will need to go in to the router in your browser window and add your new device, it will ask you for your MAC number which can be found under the back cover of your iPhone or in your WIFI settings.

Then you will need to configure your router to either automatically assign an IP Address or use an allocated IP Address and use the same setting on your iPhone. Also, you will need to configure your router to either assign a DNS Server automatically or to use an allocated DNS Server and once again you will need to use the same settings on your iPhone.

Your IP Address is crucial in oreder for your iPhone to connect to your wireless network. Your DNS Server is crucial in order for your iPhone to access the internet through your wireless network.

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?

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.
