Connecting to WiFi network-bizarre

Question

Hi, I work on a college campus with a protected network. I can connect to the wireless on my laptop, but it's hit or miss on my iPhone. I have to go through some pretty elaborate steps in order for it to work some of the time...
First, my iPhone hardly ever recognizes/remembers the network name even though I've previously connected to the internet successfully. I have to type in the network name almost every time my phone goes to sleep. Secondly, I have to change the password setting from "WEP password" to "WEP hex or ASCII" even though it is a WEP password. Furthermore, sometimes when I connect successfully to the network (there's a check beside network name), my phone still uses Edge. I've even been able to connect to the internet without typing in a password at all! I just type in the network name, select no security, and click join until it lets me join as if it's given in and let me join by virtue of my persistence...
There is no one thing I do that works 100% of the time. However, this is what I do that enables me to connect 80% of the time.
1) manually type in network name
2) type security code
3) click join a few times, unable to join
4) select no security then join
5) iphone connects, but still can't use wifi
6) choose forget network
7) choose network again and type in security code
8) voila, the internet via wifi
What the deuce is going on here? Why do I have to take such bizarre and elaborate steps to join a wireless network? I don't have this problem at home, though the one at home is an open network.
Other than this one problem, I am enjoying my iPhone immensely.

Answer 1

Just wanted to give an update to my old post.
I was having trouble connecting to a network that was password protected. After having downloaded the new software update I can now join my wireless network at work. Before my phone hardly ever remembered the network name or password let alone even find the network name. I had to manually type it in every time and hope to be connected.
Now everything works very smoothly. After the update I typed in the network name and password once, and my phone remembers it every time without my having to manually type it in. I've even put my phone to sleep several times to see if it would pick up the network again. Works every time now. I hope the recent update has done likewise for others with the same problem.
Cheers.
