All of the settings are correct. what i have on the keypad for caps is a grey background with a fully black arrow. for lower case, it is a grey background with a black outline arrow. there is no caps lock facility at all even though caps lock is is enabled. however, bizarrely what appears to be a caps shift is behaving, in so far as recognition is concerned, as caps lock. i can assure you that in respect of the wi-fi router, caps shift and caps lock are very different (confirmed by the lady at sky who supplied the router). the router is case sensitive, and evidently caps lock and shift are different. it is the same on the laptop, using caps lock gives the message that the passkey is wrong. i have upgraded all the softwear on the ipad and i have a nasty feeling that this might be hardware at fault. usually i dont use capitals to need to have caps lock but for passwords it is important. however, the nice lady at sky has enabled me to change the passkey for the router to use numbers instead of capital letters, so at least i can now connect the ipad. the problem arises if i have problems connecting, which i sometimes do, and have to reset the router. this then takes it back to factory settings and i would have to start all over again.
