How I fixed my iPhone 2wire WiFi problems.

Question

Was having problems with my iPhone I got 2 weeks ago not being able to use the At&t 2wire 2701 router I got when I bought my phone. It would see and even say it connected to the router but when I would try to get on the internet or iTunes it would go back to the Egde network. I have been reading the topics on here and saw that alot of people are having the same problem. I was able to get it working. So thought it would be nice to let you all know how, maybe it might help some of you.
1. forget the router address on your iPhone if you have it set up.
2. go into the router at http://gateway.2wire.net
3. click the "Home Network" button at the top (will ask for your password) you will see everything that is connected to the router.
4. click on "wireless settings"
5. might want to change the name of your network but thats up to you. The defualt channel is 1 so try changing to something else. Mine is at 8
6. go down to the "wireless security" change to the "wpa2-psk"
7. use a custom phrase password, they are harder to crack and I have read work better with iPhones
8. go down to the bottom section to "additional setting" my setting are as followed
Wireless mode 802.11b/g
DTIM period 1
Max connection rate 54mbps
Power setting 10
9. go the the bottom and press "Save"
10. go to "advanced setting"
11. go to the first section "Private Network" you are probably set you the default 192.168.XXXX change it to 172.16.xxx. Since this is the default means alot of people are probably using it so might be causing problems. <note by Host, not necessary, see Nathan's note below>
12. go to the bottom and press "Save"
13. exit browser and unplug the router for 1 min. Talked to a guy from 2wire and he said this sometimes helps when you change setting to reboot the router for the changes to becomes enforced by the router.
14. go into setting > Wi-Fi on your iPhone and then choose your network and enter your password.
Lets hope when you connect this time you stay connected. If this helps you please let me know. Anyway hope this helps

THANKS!!! I got my phone for Christmas and have worked for 2 full days trying to get it to say connected to my 2wire. I called Apple support and they had me reset, restore and finally go to the Apple store to exchange my phone. I kept telling them I had read that this was a common problem but they seemed unfamiliar. When I got to the store, it logged on easily to their wireless network so I was told it wasn't the phone but probably something with my 2wire. They said maybe it wasn't compatible with the iphone. I came home and have worked another couple of hours when I found your post. IT WORKS LIKE A CHARM!!! Thanks again.
