iPhone is not connecting in my home's SSID!

[DangerZone]

Hello.

I have this wireless router:
Siemens ADSL SL2-141
(Firmware: 3.63w
ADSL2+ : A2pB023k.d20h
Wireless : 3.131.35.6 )

but my iphone shows every time that it can't connect in the wireless ssid.
I've tried a public one and it worked, but mine cannot connect.
Is there something I should change?

thanks

PS: encryption is 64-bit WEP

edit: I now mentioned that some times when trying to connect from the iphone, the router disconnects from the internet and kicks out my laptop from the wi-fi.

re edit:

I just disabled security and the phone logged in the wi-fi with no prob!!
Though I cant leave the network unsecured!!

I get the following options in the security page:

Wireless Security: 64-bit WEP or.....
Authentication Type: Shared key or Open System
Format: Hexadecimal digits or ASCII characters

Key1:
Key2:
Key3:
Key4:

Default Transmission Key: 1 or 2 or 3 or 4

1. Leave it unsecured, and only allow known MAC addresses to use it. It's probably better security than WEP-64.
2. See if you can upgrade the firmware for your router.
3. Can the router support WPA? it's more secure than old WEP!

Anyone of these options may help.

good luck!
