Router used as a wireless adapter

If you ask the same question over and over, eventually you might get the answer you're expecting. Kids under about 4 years old do that to see which parent will give them what they want. It often works.

No. Nothing in the existing firmware feature set to suggest a client mode. I can't tell for sure, but it looks like it also doesn't support WDS, which methinks could be convinced to act as a client. I haven't tried it yet so I don't know if it will play. If you could figure out a way to get a command line, then perhaps some hidden features and config screens could be found.

The internal web server uses ASP templates, so just about everything from Linksys looks similar.

That's the problem. The open source WRT54G code uses pre-compiled linkable libraries for the Broadcom chipset. They won't work with any other chips.

The alternative firmware will appear as soon as Linksys releases source code for the device. You might wanna call or email Linksys and remind them.

Nope.

Yes but parents learn quickly to adapt and retaliate by using the following scheme:-

Mum: "You'd better ask your dad" Dad: "You'd better ask your mum"
