I'm thinking loosely of getting a network adapter for my PS2, and I'm wondering how I can use my wireless network seeing as it only has AFAIK ethernet ports. Would I have to route it through the PC, or can I magically use 802.11g from PS2 directly with some gizmo?
You'll need a WiFi/ethernet bridge. This is a device that turns a normal ethernet port into a WiFi connection (externally, you connect the ethernet port from the device you want to bridge into an ethernet port on the bridge itself and from there it leaves as WiFi through the antenna).
I assume you mean you have a PS 2 with no netwroking and the network adapter you are talking about is a cable ethernet one. So, you'd need to do something like this:
PS 2 <-> Network Adaptor <-> WiFi Bridge <~~~~WiFi~~~~> WiFi Access Point or Ad Hoc Network
Once you have the Network adapter installed you'll be able to assign an IP to it. This IP is then translated or bridged into a WiFi IP by the WiFi bridge. You will probably have to use a PC to configure the bridge as the PS 2 doesn't have a Web browser to access its configuration system.
Here are some links to suitable products (RJ 45 Ethernet to WiFi)
Linksys WGA54G (not to be confused with WAG54G)
Netgear ME101 (WiFi B, not G)
D-Link GameFuel DGL-3420 (WiFi A & G)
Quick notes on WiFi:
1. WiFi G (or 802.11G) is backwards compatible with B (802.11b). Therefore, it is recommended you buy G equipment as it offers 54mbps transfer rates over 11mbps of B.
2. WiFi standard A is totally different and is not compatible with either B or G. It offers the same speed of G, but uses a higher frequency in a band with less interference. It has slightly shorter range, but lack of interference may negate this in favor of A in real world usage.
3. The GameFuel brdige listed above is therefore a good choice as it covers A, B, & G standards. This leaves your options open at the other end of the WiFi network.
4. Look carefully at what security options you need for your network so you don't end up buying a bridge that cannot use WPA, for example, forcing you to disable this for the entire network to get your PS 2 online.
