Iphone Wifi question?

I dont know if you are having the same issue as i did when i connected to my wifi, but my issue was due to the network key (pword). You must type the pword using the correct upper/lower case combination. When i typed mine I realised it was all in lower case so wasnt being recognised. The arrow key when typing in to your iphone must be "lit" for upper case. Once i did this it connected fine. Hope this helps.
