Hi-
I've had a 4G touch for about 8 days and have not been able to use my home wifi network. The phone shows that I am connected to my home wifi but when I try to download content the app just clocks and eventually times out with an error message like "not connected".

The 3G network works fine. Everything else works fine except my home wifi. On the phone - in Settings | Wireless and network | Wi-Fi settings under Wi-Fi settings in Wi-Fi I see "connected to mywifi" and under Wi-Fi networks mywifi network is displayed and it says "Connected".

Here are the steps I've tried:
-Called Sprint tech support. Recommended I try connecting to a public wifi or the wifi at my local Sprint store.
-Was able to connect to a public wifi
-Was able to connect to the Sprint store wifi.
-Called Sprint tech support again but they will not help since I can connect to other wifi networks.
-Returned to Sprint store and they reset the phone (volume up button and power button simultaneously).
-Still not able to connect to home wifi.
-Returned to Sprint store and replaced the device with a new phone, same model.
-Still not able to connec to home wifi.

Here is my home setup:
-Linksys E3200 router.
-SSID broadcast disabled, WPA2/WPA Mixed security
-MAC wireless filter enabled
-Router address: 10.10.10.1
-Max users: 50
-Static DNS set
-Channel width/channel: auto
-Guest access account available

I have 2 laptops, nook tablet, 2 ipod touch's, 1 iphone, and a wii all working with my home wifi network - no issues.

Here is what I've tried at home:
-Power cycled cable modem and router
-Rebooted router using router web page
-Enabled SSID broadcast
-Disabled MAC filtering
-Tried connecting to guest account

Nothing worked. If you have any ideas on what else I try it would be greatly appreciated. Please - don't make me get an iPhone!

 

Yes - still have stock software. Current firmware version is 1.0.01 build 3 Apr 21, 2011. There is a new firmware version.Do you recommend upgrading?

 

From Linksys tech support: "Since the other devices are working fine, that means the router is working properly. It is not recommended to upgrade the firmware if it's working fine. It may corrupt the device if everything is okay."

 

Yes - is shows my router and even allows me to connect. However, when I try to download something it just times out.

 

Solved!
It had nothing to do with the phone, router or sprint. The problem was the openDNS DNS servers I had configured in my router. For some reason the phone could not find those servers. We configured the router to use the mediacom DNS server and viola! it worked. All is good.
To continue to use the openDNS DNS servers in my home network and use wifi on my phone would be to specify a static IP on my phone and specific non-openDNS DNS servers (e.g. google or mediacom's DNS servers).
I think this is an issue with openDNS and I will be contacting them.
Thanks all for your feedback.

 

My linksys router has a section where you can specify static DNS. These are servers that translate Google to an actual ip address, like 74.125.225.14. If your device can't talk to a DNS server, it will never find any web sites or other locations on the internet. For whatever reason, my phone could not find the DNS servers specified in my router configuration. When I specified different DNS servers, my phone started working.
I would recommend calling tech support for your home router or find your favorite local computer geek who might be able to help you. I was lucky enough to a neighbor that works for Cisco who helped me figure it out. Good luck!
