I entered the details manually, ssid, set it to hidden, entered the 128bit wep key, found the mac of the phone and added it to the ACL on the router (3com office connect, forget which model).
Hiding the SSID is often a major cause of wireless LAN connection problems, especially when connections drop and you can re-establish.
Thing is, hiding the SSID is one of those internet security myths. WLAN was never designed to work without it, it doesn't actually make your wireless LAN secure at all, and can cause more problems than it's worth. It's like hiding the entrance to your house. A thief will still find the house if determined, but is it worth it when the postman and legitimate visitors won't be able to find your house either? Sure, whilst it may stop the casual thief, so would just simply locking your doors, just like having any kind of encryption enabled.
Technically, it's fairly easy to snoop and get the SSID as it's broadcast in plain text whenever anyone makes a connection anyway.
Far better security is to use WPA or WPA2 security. The 128bit WEP key is better than a weaker one, but still crackable. Whilst WPA is also crackable it's very hard to crack, and the best security is achieved by just simply picking a very long key as this simply makes it impractical to crack (as it would take hundreds, if not thousands of years).
Oh, and the MAC ACL on the router isn't really secure either. Though it does help, again it's easy enough to snoop and easy to spoof also. However unlike SSID hiding, it does no harm really. Arguably it stops accidental connections by an oblivious neighbour auto-connecting, but then so would enabling encryption anyway.

I had "no gateway reply" kind of errors when I was using a wireless hotspot in the US in a hotel. This was on an open network with no WEP/WPA security (has a login page though). I put it down to shoddy coverage though despite claims of WLAN in every hotel room, as the signal would drop every few seconds. Though it may also have been down to a congested network. They must have had a lot of access points around, but still you could be talking about a lot of devices trying to connect over a limited number of channels.
I never have that kind of problem at home, and also got a connection fine on a T-Mobile hotspot at a Starbucks, and another coffee shop hotspot (the latter was free 😃).
